Standard Construction
Housing
Slip-Fit Duct Connection (QEI-I/II & QEID)
Tubular housings are constructed of welded steel to
eliminate air leakage. Integral straightening vanes are
constructed from steel and welded into place.
Inlets and outlets are designed with extended collars
for slip-fit duct connections as standard. QEI-L is
flanged as standard. Companion flanges can be
ordered for slip fit connections.
Wheel – Mixed Flow
Adjustable Motor Bases (Belt Drive)
Fabricated wheels are constructed from steel. The
blade profiles are angled and contoured for the most
efficient and quiet performance.
Rigid, heavy-gauge steel motor bases are welded to
the fan housing and include heavy-duty adjustment
screws for belt tensioning.
Bearings (Belt Drive)
Extended Lube Lines
Standard bearings are premium air handling quality,
grease lubricated, self-aligning, ball or roller type.
Bearings are selected with a basic rating fatigue life
L10 per ABMA standards, in excess of 80,000 hours
(L50 at 400,000 hours) at the maximum operating
speed for the QEI-I/II and QEI-L in the horizontal
position. The QEI-L bearings are selected with a
basic rating fatigue life L10 in excess of 50,000 hours
(L50 at 250,000 hours) in vertical position.
Belt drive units have nylon lubrication lines with
grease fittings that allow bearing lubrication without
disassembling the fan. Grease fittings are mounted
on the outside of the fan housing. Direct drive
units have extended lubrication lines for the motor
bearings, if required. Smaller frame sized motors are
typically sealed and not lubricatable.
Permatector™ Coating
Bolted Access Door
Greenheck’s Permatector coating is a thermosetting
polyester urethane, electrostatically applied to
provide uniform thickness and a clean appearance.
Permatector coatings also provide excellent
corrosion characteristics for general applications,
both indoor and outdoor. For corrosive environments
(ie. coastal), see page 9 for information on our zincrich basecoat technology.
A bolted access door provides an opening through
the fan housing for cleaning or visual inspection of
the wheel. A hinged access door is available as an
accessory.
Belt Guard (Belt Drive)
A totally enclosed belt guard provides protection
from rotating pulleys and belts. Belt guards meet
OSHA Standards.

Value Added Features
Quality Assurance Test
Before shipment, all Greenheck mixed flow fans are tested at the design speed after final assembly.
QEI-L fans are checked for amp draw and the levels are recorded. QEI-I/II and QEID fans are
subjected to a complete vibration analysis. The maximum allowable vibration on a QEI-I/II at the fan
bearings is 0.15 in/sec. peak velocity for the specified RPM. QEID maximum vibration is 0.08 in/sec.
peak velocity on the fan housing for the specified RPM. A record
of the vibration test result is available upon request.
By performing the vibration test, we are able to provide more than
wheel balancing, it is also a diagnostic tool for finding potential
problems. A defective bearing or motor, bent shaft or misaligned
sheaves may cause excessive vibration. A
complete vibration test will uncover
these problems before the fan leaves
the factory.
Electrostatic Powder Coatings
Powder coatings offer a uniform, durable and high-quality finish.
Standard powder coating is a one-coat process applied over
a phosphatized surface that generally meets or exceeds the
corrosion resistance of a comparable wet paint.
Greenheck offers a number
of in-house coatings applied
via “electrostatic powder.” The
standard coating, Permatector™,
is excellent for indoor or outdoor
applications and is resistance to
many common chemicals. Consult
Greenheck’s Product Application
Guide, Performance Coatings for
Ventilation Products, for a complete
listing of coatings and a relative
resistance chart. For corrosive environments (i.e. coastal), see page 9
for information on our zinc-rich basecoat technology.
Maintenance / Serviceable Construction Advantages
The following value added features are incorporated into the design to allow for quick and
easy field service.
QEI-L and QEI service advantages:
• Bearing lubrication is performed through extended grease fittings located on the
outside of the fan housing.
• The entire shaft and bearing assembly can be removed as a single assembly from
the inlet end of the fan housing.
• An adjustable motor base is provided for tightening the fan belts.
QEID service advantages:
• Extended lubrication lines are provided for motor bearing requiring lubrication.
Smaller frame motors use sealed bearings and are permanently lubricated.

Inlet and Outlet Sound Power Levels
All Greenheck mixed flow fans have AMCA licensed sound power levels for both the
fan inlet and outlet.
Application and installation determines which sound power reading (inlet, outlet,
or both) is critical. The differences between the generated sound from the inlet and
outlet are important and noticeable. AMCA licensed inlet and outlet sound power
data provides complete sound information to select a fan based on the acoustical
requirements. For additional information on sound, refer to page 6.
Greenheck’s Sound Lab
Field Rotatable Housing / Compact Size
The QEI-L and QEI are designed to accommodate changing fan
mounting positions and motor orientation in the field. Mounting
fixtures are securely bolted to the fan casing and can be relocated
to reposition how the fan is installed or the position the motor is
oriented. Flexibility in a motor’s location is important for easier
access and can determine where the unit will fit. Last minute
design changes or unexpected obstacles during installation are
no longer a problem.
Greenheck’s mixed flow fans were designed for compact size.
Keeping size to a minimum is important when fitting into tight
spaces like mechanical rooms or air handlers.
Slip-Fit Duct Connections
The inlet and outlet ends of the QEI-I/II and QEID are designed to
accept “slip-fit” connections. Often companion flanges are bolted
to a fan’s inlet/outlet flange to provide a slip-fit connection for a
flexible sleeve, as with the QEI-L. This extra step is now eliminated
by directly attaching the flexible sleeve to the duct and fan. This
saves time and money in the installation process.
It is recommended to use a flexible sleeve connection instead of a
rigid duct connection.

Design & Performance
Mixed Flow: Axial/Centrifugal Hybrid
Centrifugal
Static Pressure
A mixed flow wheel is a hybrid between an axial propeller and a
centrifugal wheel. The result is a design that combines the best axial
and centrifugal properties: highly efficient air movement, increased
pressure capabilities, extremely low sound levels, and a steep fan
performance curve. To further enhance the fan’s performance,
straightening vanes are incorporated in the housing. These serve
to convert swirling airflow into a straight axial flow with a resulting
static pressure rise and energy savings.

Sound and Efficiency
Sound power levels and fan efficiency are two very important factors when selecting a fan. There is a noticeable
difference between impeller types. The table and chart below compare the sound power (LwA) and the static
efficiency of the belt-driven mixed flow fan wheel versus tubular centrifugal and vane axial inline fans. Over a
wide range of operating points, the mixed flow fan provides the quietest and most efficient selection.

The sound quality of the belt-driven mixed flow fan line is
as beneficial to low sound design as is the reduced overall
sound power. The sound chart compares units of similar
outer tube diameters at an operating point of 20,000 cfm with
1.5 inches wg of static pressure (Ps). Tubular centrifugals
(green) have dominant tones in the 63 Hz through 250 Hz
octave bands, while vane axials (red) have more mid to high
frequency sound. The mixed flow fan (blue) does not have a
dominant tone. A bystander would hear a more bland sound
that is quieter than a tubular centrifugal or vane axial.
Wheel Characteristics
Belt Drive: Fan Class
Class I and II fans have different wheel designs with different performance characteristics.
Class I mixed flow wheels are optimized for performances involving low pressures and high volumes. Class II
wheels are designed for a steeper fan curve with higher pressure capabilities. This is illustrated in the graph
with the two different class wheels plotted at identical fan RPMs.
When selecting a mixed flow fan, it cannot be assumed that moving into a Class II fan will produce the same
results as a Class I mixed flow fans. Model QEI-L utilizes a Class I wheel.
Static Pressure
Class II
Class I
CFM
Direct Drive: Percent Wheel Width
Direct drive mixed flow fans are optimized for performance requirements by the use of partial width wheels. This
is necessary because the fan RPM is commonly fixed and identical to the motor RPM. A reduction in the width
of the wheel (or the air passage) results in reduced airflow capacity and a steeper fan curve. This is similar to
the effect of a reduced pitch in a direct drive vane axial fan. QEID wheels are available in 5% increments from
50 - 100% wheel width.
Static Pressure
QEID fans can be used in conjunction with variable frequency drives (VFD’s) for variable air volume (VAV)
systems. In these applications, the wheel width is optimized to ensure efficient operation and stable
performance throughout the turndown range. VFD’s are also used for final system balancing and to reduce the
airflow when building requirements are reduced. In this case, the fan and wheel width are selected using the
final design CFM and static pressure.

Sound Power versus Sound Pressure
The sound values displayed on the performance pages are in terms of inlet sound power (LWi A) and outlet sound
power (LWo A). These values are the acoustic power radiating from the inlet and outlet of the fan, respectively.
Sound pressure, expressed as dBA, is the acoustic pressure at a point in space which can be measured with a
microphone or can be heard. To convert sound power (LwA) into sound pressure (dBA), the following corrections
are applied for a hemispherical free field.

Optional Features
Sure-Aire™
The Sure-Aire™ flow monitoring system measures fan
flow within a 3% accuracy. Unlike traditional flow probes
mounted in the fan venturi that create a system effect
hindering fan performance, Sure-Aire™ does not interfere
with airflow and will not impact the fan’s air or sound
performance. This option is available on all mixed flow fan
models and ships completely assembled from our factory.
An electronics package with pressure transmitter and
digital read out is available with the Sure-Aire™ system. The
electronic kits are available for 50 or 60 Hz power supplies
upplies
and provide either a 4-20 mA or 2-10 VCD output that
at can
be tied into the building’s automation system.
Sound Sensitive Areas
Sound Vault Housing - Radiated Sound Enclosure
The sound vault housing is an excellent product for fans that will be positioned adjacent to an occupied work
space or in sound critical applications. It locks in radiated sound from the fan casing, motor and drives, and
minimizes vibration transmission. Standard construction includes an acoustically lined housing, integral spring
isolators, and internal flexible connections at the fan’s inlet and outlet to effectively isolate the fan from the
system. Vertical or horizontal mounting configurations are available.
Why use a Sound Vault?
• Sound power attenuation levels determined by
sound intensity tests on actual units
• Ships fully assembled with fan
• Internal isolation to limit breakout noise
• Access panels for inspection of fan and motor
• Bearing lubrication lines extended to outside of
enclosure
• Formed mounting rails with prepunched holes
for easy installation
• Available on both QEI-I and QEID through
size 27 fans

Optional Two-coat
Paint System
In 1972, Greenheck took the lead as the first commercial and industrial fan manufacturer to introduce
electrostatic powder coatings. Today, Greenheck continues to lead by being the first to offer a superior zinc-rich
powder basecoat and powder coating finish.
This zinc-rich basecoat technology is used extensively outside the HVAC industry to protect bridge beams,
automotive components and other heavy-gauge steel products. Now, this advanced technology is available on
Greenheck welded steel products.
Greenheck’s coating process starts with a minimum of five wash stages to treat all components prior to
painting. Cleaner parts result in better coating adhesion and durability. We then use an advanced two-coat
powder application method that includes a basecoat of zinc-rich powder and a topcoat of Greenheck’s
Permatector™ or Hi-Pro Polyester. The combination of these two topcoats over the zinc-rich basecoat results
in the two-coatings, Perma-Z and Hi-Pro-Z. These oven-cured coatings provide superior corrosion resistance
along with a tough, uniform finish to combat the most extreme conditions.
Zinc Advantage
When compared to a traditional single coat
application, the benefits of the two-coat
system include:
One Coat Process
Topcoat
• An automatic powder coat application
that produces uniform coverage and
unmatched paint quality.
• A double coat thickness that provides
superior durability and protection from
air and water.

(70% zinc)
Topcoat
• A zinc-rich basecoat that includes
an epoxy component that provides
additional corrosion protection.
• A zinc-rich basecoat that provides

The protection offered by the zinc-rich basecoats in
Perma-Z and Hi-Pro-Z result in extraordinary corrosion
resistance. Test data demonstrates our two-coat paint
system offers three (Perma-Z) and four (Hi-Pro-Z) times
the corrosion resistance of other coatings commonly
available within the fan industry. See table for salt spray
life for various coatings.
Coating fans with Perma-Z or Hi-Pro-Z has reduced our
customers annual paint maintenance costs by three to
four times!

High Efficiencies = Lower Operating Costs
Example of Annual Operating Cost Savings
For a system performance requirement of 25,000 cfm at 2.5 inches of static pressure (wg) the corresponding
operating power requirements are 13.97 Bhp with a QEI-I size 36 and 19.8 Bhp for a size 36 tubular centrifugal fan.
Formulas:
- Kilowatt-Hours = (Operating Power (Bhp) x 0.746 x Hours of Operation) / Motor Efficiency
- Operating Cost = Kilowatt-Hours x Power Cost per kW hour
Assumptions:
- Cost of electricity is $0.09 per kilowatt hour
- 3,120 annual hours of operation (12 hours per day, five days a week, 52 weeks a year)
- 93.0% motor efficiency (equal to NEMA Premium minimum efficiency for 15 and 20 hp, ODP, 1725 rpm motor)
Tubular Centrifugal Fan
QEI-I - Mixed Flow Fan
kW-Hours = (19.8 Bhp x 0.746 x 3120) / 0.93 = 49,554
kW-Hours = (13.97 Bhp x 0.746 x 3120) / 0.93 = 34,963
Operating Cost = 49,554 x $0.09 = $4,460
Operating Cost = 34,963 x $0.09 = $3,147
Annual Operating Cost Savings = $4,460 - $3,147 = $1,313

Roof Upblast & Spark Resistant
Construction
Roof Upblast
Models QEI-I/II sizes 9 through 54 and model QEID
sizes 12 through 54, are available in roof upblast
configuration. The roof upblast configuration is ideal
for exhausting contaminants away from a building to
prevent roof damage and re-entrainment of exhaust
air. Both QEI-I/II roof upblast models have the high
temperature UL rating and can be used for emergency
smoke exhaust applications.
Standard construction includes a fully-welded heavygauge curb cap to eliminate leaks, a butterfly damper
section for backflow prevention, and a windband
section to protect the butterfly dampers from debris. A
complete line of roof curbs is available for mounting to
a roof deck.

shaft and bearings. Welded steel vanes
shall straighten the flow of air from the fan
discharge.
All QEI-L and QEI-I/II units up through size
27 shall incorporate a universal mounting
system that allows the fan to be mounted in
either vertical or horizontal configurations
and field rotation of the motor position in
90 degree increments. Bearing life shall not
be reduced below specified level in different
configurations. QEI-I/II units size 30 and
larger shall allow for field rotation of motor
positions. Units shall accommodate base
mount or ceiling hung mounting without
structural modifications to the fan.
The wheel shall be of the mixed flow type.
Wheels shall have a wheel cone, spherical
back plate and single thickness cambered
blades. Wheels shall be statically and
dynamically balanced to balance grade
G6.3 per ANSI S2.19. The wheel cone and
fan inlet cone shall be carefully matched
and shall have precise running tolerances
for maximum performance and operating
efficiency.
Each assembled fan shall be test run at
the factory at the specified fan RPM. The
maximum allowable fan vibration shall be
0.15 in/sec. peak velocity, filter-in for
QEI-I/II with signatures taken on each
bearing in three planes; horizontal, vertical,
and axial. Maximum vibration of 0.08 in/sec.
peak velocity, filter-in for QEID in a single
plane on the fan housing. This report shall
be provided at no charge to the customer
upon request.
