however, depending on the conditions of use (e.g. long pipes) it
may be necessary to further reduce noise at the ends of the
piping. In such cases, insert this auxiliary pipe silencer midway
along the pipe, or at the end.

Air-flow resistance
●Cautions for maintenance and checking of air filters
(1) Clogging of air filters differs with conditions of use.
Check periodically.
(2) When cleaning and replacing the element, remove it to
ensure that dust and particles do not fall into the ring
blower. Remove dust and particles which have
collected inside.
(3) If the element contains water, air-flow resistance will
increase, with a consequent drop in efficiency, and its
strength will deteriorate. Take care to ensure that
moisture and water droplets do not enter the element.
(4) The element is a consumable, and spares should be
kept available if conditions of use are bad.

Cautions for trial manufacture
(1) If welding the cooling air opening silencer into the main unit,
attach the sound insulation after welding to prevent damage
to it.
(2) Minimize all holes and gaps outside the cooling air path (e.g.
cooling air opening).
(3) Ensure that sound insulation is at least 20 mm thick. Thin
sound insulation reduces effectiveness.
Remarks

(4) Ensure that the inside dimensions of the box are sufficient. If
the dimensions are too small, the cooling effect, and
sound-absorption, will be reduced. When fitting thick sound
insulation, the internal dimensions of the box must be
increased accordingly.
(5) The D3 dimension above assumes an SGP pipe connection.
Ensure that dimensions are adjusted accordingly if other
piping is used.
(6) Shape and position of wiring holes are determined by the

Characteristic curves
(1) Characteristic curves in this catalog are in accordance with JIS B 8330 and Z8762, and show an air volume-static pressure
characteristic at an intake air density of 101kPa (at 20℃). Variation in air volume at intake is ±10% from the resistance curve.
(2) Solid line characteristic curves indicate that continuous operation is possible. This range of use extends up to cut-off pressure for
intake operation, and to near the cut-off pressure for discharge operation. When used in high-pressure discharge operation, care
is required to ensure that the range of use is not exceeded. A bypass hole may be required in the pipe when used at the cut-off
pressure.
Bypass holes for discharge operation
Always ensure that a bypass hole is provided
in the pipe for safety reasons, when using near
the cut-off pressure in discharge operation.
Refer to the table at right (VFZ Series) for
bypass hole diameter.

Parallel operation
Parallel operation with two or more units is possible (see below).
Discharge parallel operation
Intake parallel operation
When blowers are operated in parallel, pressure characteristics remain unchanged, and airflow increases by the number of units (see below).
Since airflow increases, the load on the blower also increases, and the usable range is displaced on the graph.
Care is required to ensure that operation does not exceed the usable range.

Model selection
These blower characteristics vary considerably depending on piping conditions. Losses due to pipe length
and joints are greater than initially apparent, and piping should therefore be designed for minimum
length, and minimum number of curves (e.g. elbows), joins, and valves. Pipe diameter should be as close
to the blower discharge diameter as possible. A number of model selection examples are provided below.

Environment
Do not use in, or transport through, locations where corrosive liquids (alkali acids, acids) and gases

Dust etc.
Avoid use in locations where dust and lint etc. are present.
If such locations cannot be avoided, fit a filter to ensure that the material does not enter the blower.
(Periodically remove dust etc. adhering to the blower.)
Ventilation
Always select a location with good ventilation. Do not use in closed rooms or cases.
Peripheral area
Install in a spacious area to facilitate checks and maintenance.
Vibration
Install the blower in a manner which ensures that it is free from external vibration.
If such vibration cannot be avoided, implement anti-vibration measures to ensure that the vibration is not
transmitted to the blower.

Inverter operation
Operating frequency is between 5 Hz (rotating) and 60 Hz.
Do not operate at more than 60 Hz under any circumstances.
Furthermore, resonance is possible depending on the blower installation conditions. Ensure that the resonance point is avoided in operation.
Frequency of use
Frequent use may have a negative affect on the motor, and may result
in motor burnout. Ensure that the duration of operation is in accordance
with the guidelines in the table at right. A method of switching valves
etc. (with continuous operation) is recommended if this duration is to be
exceeded. Furthermore, when operating in forward and reverse, ensure
that operation in the new direction is started only after a complete stop.

Cleanliness
These blowers are manufactured for general industrial use, and discharge air is not in accordance with cleanliness classes.
Please note that in applications in which adherence of foreign matter is not permitted, or when a high cleanliness class is required, it will be
necessary to fit filters etc.
Range of use
Emblem
As the airflow through the ring blower is reduced, internal temperature increases, and
care is required to ensure that the range of use does not exceed the characteristic curves.
Furthermore, when using VFZ50 and 60 types in intake fully closed applications, always
ensure that the emblem on the unit (top of intermediate bracket) is removed before
installation.
Operation without removing the emblem may result in deterioration of the motor
insulation and burnout.
