Use application
Gust Blowers are suitable for handling air and other non-flammable, non-corrosive, and non-explosive gasses.
The product is designed to withstand continuous operation; however, please note that in cases where the
application involves frequent and repeated interruption during operation, or high ambient temperatures, the
temperature may reach the allowable maximum temperature. Please contact us for further details. Remove
solids and impurities to keep them from entering the Gust Blower.
Intake and compression pressures
When using the Blower near a closed area, the temperature will rise due to motor overload and heat
compression. Install a pressure-regulating valve on the intake side or discharge side, or make a
bypass hole to release air.
Temperature
The allowable maximum ambient temperature and gas temperature at the intake is 40°C.
The temperature of the casing will be very high during operation. Be careful not to touch the casing;
otherwise, you may suffer burns.
Installation
Gust Blowers can be installed in any axial direction; however, be careful not to install the product in a
direction that prevents its cooling effect. Keep the air grating and opening clean. Direction of air flow
is shown with an arrow.
When installing Gust Blower close to a wall, the minimum clearance between the wall and Gust Blower
should be:
U2S-40T/70T/150: 20 mm
U2S-220/750:
30 mm
The Blower is equipped with a built-in silencer to reduce flow noise during operation. To further
reduce the noise generated when taking in or discharging free gases, install a silencer (option). Do not
attach components to the Gust Blower that conduct or radiate noise (e.g. thin wall, metal plate). If
necessary, install a sound absorbing layer in the middle. The piping should be arranged so that it will
not cause stress deformation of the Blower.
Wiring
Make sure to turn off the power before starting the wiring work.
Wiring of the Blower should be performed by a qualified electrical contractor. The power supply voltage
and frequency should be equal to the nameplate values. Refer to Figure 1 and arrange and connect the three
leads attached in the terminal box according to the power supply voltage and frequency to be used.
