AC Centrifugal Fans / Blowers

Centrifugal Fans / Blowers

Centrifugal blowers move air by means of the centrifugal force generated by rotating a cylindrical runner on which blades have been arranged. Centrifugal blowers have a small outlet, which concentrates air in a single direction and are therefore suitable for local cooling. They also create large static pressure, making them optimal for cooling equipment through which air cannot flow easily and for airflow through ducts.

Centrifugal Fan / Blower

Cooling with High Static Pressure

The high static pressure of centrifugal blowers makes them suitable for cooling used together with thick filters that are subject to significant pressure losses.

High Static Pressure

Air-Blow Cooling or Drying

Centrifugal blowers offering high static pressures are suitable for the air-blow cooling of work pieces following a heat treatment.

Fan Kits Available

Various accessories will help you improve the safety and utility of fans. We recommend our fan kits, which combine the fan and necessary accessories in a convenient package.

Example:

Thermostat Available for Energy Saving

Thermostats (sold separately) make it possible for fans to operate only when cooling is necessary. Thermostats provide energy-saving by automatically stopping fans for example, at night, when the amount of heat generation declines following the load rate's decline in equipment, or in winter, when the ambient temperature drops and forced cooling is not necessary.

Thermostat

Thermostats automatically perform ON/OFF fan control in accordance with the temperature fluctuation inside the equipment. It helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.

Mounting Brackets

Mounting bracket using the motor case of the centrifugal blower.

Fan Size	Model
1.97 in. (50 mm)	PAS2B
2.36 in. (60 mm)	PAS2B
3.15 in. (80 mm)	PAS4B
3.94 in. (100 mm)	PAS4B
4.72 in. (120 mm)	PAS6A
6.30 in. (160 mm)	PAS5A

Finger Guards

Finger guards prevent fingers or foreign objects from entering the fan. Finger guards are mounted to the fan frame using bolts.

3.94 in. (100 mm)	FGB10
4.72 in. (120 mm)	FGB12

Filters

When using a fan to cool machinery, dust may accumulate inside the machinery after long periods of operation. Depending on the parts involved, this could cause a malfunction. These filters prevent dust from entering the device, keeping the air inside the machinery dust free.
