when used to remove particulate buildup from the clean air plenum
• No manual handling of dust - dust flows directly into the collector’s
hopper, eliminating the need to remove the bags for cleanup
• Easy installation - simply attach the Vacutrans to the discharge hose
and connect air
• Virtually maintenance free - there are no moving parts to lubricate
or wear out
Portable - can be easily moved between compartments or collectors
• Uses the compressed air you have - operates in the 150-200 CFM (4.2m3/
min–5.7m3/min) range at 100 psi (6.90 bars)

Clean-On-Demand Baghouse Control Systems
CLARCOR Industrial Air offers a full line of baghouse control systems designed
to achieve maximum ventilation and collection efficiency. Clean-On-Demand
controls monitor the differential pressure across the filter bags. The user sets
the high and low differential pressure set points (generally 1/2” w.c. (12.7­mm
w.c.) apart), whereby cleaning will start and stop. By operating the baghouse
at a stable and optimum differential pressure, you are not over-or undercleaning the filter bags.
Benefits of Clean-On-Demand Controls
•Maintains optimum dustcake for filtration efficiency
•Helps protect bag fabric from blinding and bleed-through
for better airflow and less emissions
•Less flex cycles on the filter bag for increased filter bag life
•Maintains stable ventilation at the process with no pickup of
extra material caused by over ventilation or back puffing caused
by under ventilation
• Helps lower compressed air consumption and operating costs
Standard Clean-On-Demand Controller
•Solid-state construction
•Digital input of pulse time, pulse duration, number of valves
•Low profile Photohelic gauge with high and low differential pressure
set points
•NEMA 4 (IP66) enclosure
Differential Pressure Transmitter
Installation of timers can enhance
baghouse performance.
The CLARCOR Industrial Air Differential Pressure Transmitter includes a
Magnehelic gauge with 4-20 mA output housed in a NEMA 4X enclosure. The
Magnehelic gauge gives local differential pressure indication, while the 4-20 mA
output gives continuous remote indication of differential pressure.

products and services.
Bag-to-cage fit is critical for proper performance and collection efficiency.
Maximize Filter Bag Life
The type of cage you buy will affect the life of your filter bags. Cages should
be designed to optimize filter performance and promote longer bag life. Poorly
manufactured cages allow over-flexing of the fabric, abrasion, holes, and
eventually lead to filter failure.
Avoid crimped or scalloped bottom pans, tapered or bowed cages, and cages
that have wires welded on the outside of collars or pans.
The CLARCOR Industrial Air Cage Difference
CLARCOR Industrial Air manufactures cages for use in most baghouses. Properly
designed cages serve as critical baghouse components for optimum bag
performance and durability. Our cages are constructed of the following materials:
• Low carbon steel (bright basic wire)
• Type 316 stainless steel
• Type 304 stainless steel
• Other specialty materials
• Galvanized low carbon steel
Cage top
We also offer rigid wire cages with all bottom pans welded to the inside.
Our cages offer the following benefits:
• Rounded edges on top collars and bottom pans - The top collars and
bottom pans are stamped from durable 20 gauge steel, with rounded edges
to reduce abrasion.
• Consistent spacing of rings and wires - The stringer wires in our cages
are placed perpendicular to rings and consistently spaced so that the cage
diameter is the same from top to bottom. This will promote a proper
bag-to-cage fit.
Wires welded on the inside of collars and pans - The top collar and
bottom pan are attached with the wires welded on the inside, helping
to avoid premature bag failure.
Precision welding and polishing - Rings between the stringer wires are
welded and polished to reduce burrs and sharp edges. We also use a weld
bead at the top and bottom of the cage, allowing a point of contact weld that
is much stronger than welding directly to the roll flange or pan.

BHA Visolite Leak Detection
One of the brightest leak detection products available for baghouses — we invented it!
Locate Leaks in Your Baghouse Quickly and Easily
The BHA Visolite Leak Detection System reduces the time plant personnel spend
identifying tears, holes, and bad seals in bags. BHA Visolite is a lightweight fluorescent
powder that is injected into the baghouse. The powder follows the path of least
resistance, accumulating around the source of leakage, whether it is a weak area in the
filter media or a bad seal. A black light is then used to pinpoint the exact location of air
leakage and its severity.
BHA Visolite glows
under the light to
reveal air leaks in
the baghouse.
BHA Visolite Powder-Usage
To determine the quantity of tracer compound needed to run one BHA Visolite test,
follow these guidelines:
•For every 1,000 ft2 (93 m2) of filter cloth, one pound of Visolite is needed.
To calculate filter cloth area in your system use the following formula:
Total Cloth Area, ft2 (m2) = (Bag Diameter (in or mm)
x 3.14 x Bag Length (in or mm))
x Total # of Bags
•If filter cloth square footage per compartment or baghouse is known,
divide by 1,000 to obtain the number of pounds of BHA Visolite powder to use.
The powder quantity may vary depending on the length of ductwork
between the fan and baghouse.
Three Colors for a Variety of Industries
BHA Visolite is available in four different colors and incorporates a varying particle size
distribution to minimize fabric bleedthrough. Straight pigment is also available for specific
applications. It is important to choose the appropriate color for your specific application:
• Pink - all industries
• Orange - all industries except those where iron oxide is present
•Green - aluminum, cement, and utility industries; good contrasting color for pink
and orange
BHA Visolite Leak Detection Inspection Lights
CLARCOR Industrial Air offers a variety of black lights to use with the BHA Visolite leak
detection powder. Lights that are designed
for use in pulse-jet, reverse air and shaker
baghouses. Selections include powerful,
rechargeable, high intensity UV-A inspection
black lights with state-of-the-art, ultra-hi-flux
technology available. Cordless, rechargeable
and powerful with long life.
BHA Neutralite Powder
Creates a more efficient and porous dustcake.
The Importance of Building a Protective Dustcake
For a baghouse to operate efficiently, the fabric filters must capture and
release particulate during the cleaning cycle. The effectiveness of this process depends on the
development of the dustcake (initial control layer of dust) that protects the fabric interstices. A
variety of particle sizes and shapes are needed to produce an efficient and porous dustcake.
Particles that are similar shapes and sizes will form a very dense dustcake that
restricts airflow.
BHA Neutralite vs. Other Precoats/Conditioning Agents
BHA Neutralite consists of microscopic particles that vary dramatically in shape, while most
other precoats only have one particle size. Neutralite is also lighter than lime and flyash and
will not fall off the bags during cleaning. Don’t throw money down the hopper by using precoats
that don’t work properly in a baghouse application.
Fly Ash
Diatomaceous Earth
• Alkaline by nature
•Presence of sulfur can
form gypsum, leading
to plugging or blinding of
filter bag
•Similar particle size
creates dense,
compact dustcake
• Generally abrasive
•Varying pH from highly
acidic to very basic
•May require pretreatment
to alter hazardous
material makeup
•Material is heavy and
often falls off bag
•Typically used for wet
filtration applications
•Introduces moisture and
hydrocarbons into the
gas stream
•Moisture binds the
diatomaceous earth to the filter
surface causing permanent
blinding and loss of airflow
•No detectable free silica
content for a safer work
•Light density aluminum
silicate powder
•Varied particle size to
prevent blinding of filters
•Works in a variety of
•Absorbs hydrocarbons,
moisture, and sparks
(BHA Neutralite SR)
•Proven to help lower DP,
increase airflow, and lower
BHA Neutralite SR (Spark Retardant)
If your op­er­a­tion has the potential for hot sparks in the gas stream entering the
baghouse, BHA Neu­tralite SR Powder can help protect your collector. It offers
the same benefits as regular Neu­tralite pow­der, plus it:
•Provides­a protective barrier between the fabric and sparks in the gas stream
•Helps extinguish sparks before they damage the bag
•Absorbs up to 300% its weight in moisture and 250% its weight
in oil and hydrocarbons to help prevent filter bag damage
Independent testing by the Southern Research
Institute showed that BHA Neutralite increased
collection efficiency dramatically, while operating at a differential
pressure 3 to 4 times lower than operation without an
initial dustcake of BHA Neutralite.
By injecting an initial dustcake of BHA Neutralite
powder, the fabric is protected from the particulate,
while still allowing airflow to pass through the
dustcake. The result is lower differential pressures
and higher col­lec­tion efficiency.
Protection for your filter investment. When you buy new filters, buy new clamps.
CLARCOR Industrial Air Clamps are Designed to
Protect Your Filter Bags and Make Installation Easy
Our clamps increase bag life by decreasing leakage and abrasion.
Each clamp is designed specifically to ensure bag sealing and make filter
installation simple. We offer a variety of designs and sizes engineered
to meet your particular needs. They can be used with raw
edge, cord, hem, or sleeve constructed bags and some
pleated filter elements. There are several
reasons why clamps can fail:
• Reuse of old clamps
Our dust collector experts recommend replacing clamps each
time you change out your filter elements.
Worm Gear/
Latch Combination Clamp
• Designed with a worm gear connection for tightening upon installation
• Designed with a latch assembly for quick removal
• Constructed of 300 series stainless steel and has a 9/16-inch (1.43 cm) band width
Quick Release Clamp

on the clamp as it is tightened
Provides proper support to filter bags.
Tensioning is Critical to Reverse Air Baghouse Operation
Improper tensioning is one of the main causes of bag failure in reverse air
baghouses. Excessive tensioning causes harmful stress on the fabric yarns
and sewing threads and also prohibits movement necessary for dustcake
release. We have developed many tensioning assemblies to best fit your
application. The assemblies are available in chrome silicon steel for
moderately elevated temperatures or 17-7 PH stainless steel for high
temperature applications.
Conical Spring
Unlike a linear spring, which compresses equal amounts for equal
pounds of load applied to it, the conical spring becomes harder to
compress as heavier loads are applied. In this manner, it acts as a
shock absorber, preventing the fabric from total collapse while under
the reverse air cycle. It also reduces any “popping” effect on the bags
when returning to service. This spring is used in the I-Bolt and Double
Draw Bar Assembly and the Pre-Loaded Rod and Draw
Bar Assembly.
I-Bolt Assemblies
I-Bolt and Double Draw Bar Assembly Features and Benefits
• Hitch-pin design allows for ease of maintenance when re-tensioning
•Easy adjustment and installation reduces labor that is normally associated
with threaded bolt assemblies
•Provides the necessary tensioning to maintain proper collection efficiency
• Prevents bag-to-bag abrasion
•Features a patented cup washer centering the spring on the bolt, which
resists spring buckling and abrasion
•Provides non-linear compressibility, supporting both the bag and dustcake,
allowing fabric the necessary movement to clean while preventing bag collapse
•Provides the required pre-load and travel for proper tensioning
Tensionor Suspension System
Our Tensionor Suspension System adjusts the filter bag/cap
assembly to the proper tension, providing the following benefits:
•Prevents abrasion caused by improperly tensioned bags that droop
into thimble
• Easily installed in shaker or reverse air without the use of hand tools
•Helps reduce fan horsepower requirements due to lower pressure
across the filters
•Increases filter bag life by minimizing flex fatigue and abrasion at bottom of filter
Tensionor Suspension System
AC Tensioning Tool System
The AC Tensioning Tool System is a precision tensioning device used with our I-bolt
and double drawbar tensioning assemblies providing accurate, consistent bag
tension significantly faster than conventional methods.

Door Seal/Access Doors
Help prevent outside air from leaking into the system.
Avoid Corrosion, Emissions, and Production Loss by
Keeping Access Doors Sealed Properly
A door seal is one of the most overlooked issues in dust collector maintenance.
If your doors are not sealed properly, many problems can occur within
your system, including:
• Corrosion of doors and walls
• Fugitive emissions
• Production losses
• Maintenance problems
• Reduction of airflow across filters due to condensation and blinding
CLARCOR Industrial Air has developed a variety of door seals to prevent leakage
of outside air into your air pollution control (APC) equipment.
Helpful Maintenance Tips
• Replace old door seal
• Make sure the door is not warped and seals tightly
• Avoid repeated opening of access doors, which often moves the seal

Keep Differential Pressure in Check with Pressure
Measurement Gauges
High differential pressure in the baghouse can cause damage to filter bags,
decrease airflow in your baghouse, and increase operating costs. You can monitor
differential pressure with one of our pressure measurement gauges, and even allow
your collector to clean on demand!
Magnehelic* Gauge for Continuous Pressure Measurement
The Magnehelic gauge is used to measure the differential pressure between the
clean gas side and the dirty gas side of the baghouse, which is the bag’s resistance
to the airflow. A sudden drop in pressure denotes a leak in the system. A sudden
or sharp rise in pressure denotes that the filter bags are becoming blinded or “caked”
with particulate. The Magnehelic gauge is the best indicator of your baghouse’s
current operating status, and offers critical information when troubleshooting.
Photohelic Gauge to Incorporate Clean on Demand
The Photohelic gauge is a Magnehelic gauge with the capability to allow a collector
to clean on demand. In addition to measuring differential pressure between the
clean and dirty sides, the Photohelic gauge allows you to set high and low pressure
points. When the actual differential pressure reaches the high point, a relay signals
the pulse system to activate cleaning. While cleaning, the differential pressure will
fall to the low pressure point and a relay signals the pulse system to stop cleaning.
Surge Valve Provides Fast and Easy Cleanout of Gauge Lines
The Surge Valve is a three-way valve that allows fast and easy cleanout of
Magnehelic and Photohelic lines without disconnecting the lines to manually clean.
A surge valve can eliminate
plugged lines.
The ball valve is designed to protect the gauges from breaking under high pressure
cleaning. The benefits of the surge valve include:
•Simple to operate – close the valve and a push of a button cleans the
entire line in seconds, making it a fast, easy way to keep the lines clean.
• Can be connected to a timer for automatic cleaning.
• Withstands temperature ranges from 32° F (0° C) to 200° F (93° C).
•Heavy duty construction makes it suitable for service up to 150 psi
(10.34 bar) pressure.
Diaphragm Valve
Auto Purge Valves Help Prevent Corrosion and
Agglomeration in the Baghouse
The CLARCOR Industrial Air automatic purge valves are designed
to help eliminate water buildup in the compressed air header of a
pulse-jet system. Without the purge, water from the compressed air
can enter the baghouse and cause corrosion to filter bags
and an agglomerated, hard-to-clean dustcake. The valve is
installed at the bottom of the air header assembly and is
connected to a pulse valve. When the pulse valve fires, the
valve opens the purge valve discharge port on the air header
assembly, removing excess moisture.
