Fans & Blowers

Backward Curve Fans

189 189 ESI

Backward Curve Exhaust Fan Design

We manufacture Backward Curve fans for a custom pneumatic system in Ontario. Our Backward Curve exhaust fan design meets the highest standards.

  • 4000 to 150 000 cfm
  • 18” to 98” wheel diameter
  • Up to 30” of water

The MacDonald Steel Backward Curve (BC) fan casing is manufactured from reinforced heavy plate construction.

The BC fan is a high efficiency exhauster, using 25% less power than conventional exhauster designs. The BC’s efficiency is derived mainly from its unique impeller. Its dimensions and backward curved blades have been purposefully designed to operate in the flow and pressure ranges required by dust collection systems.

The BC fan remains efficient over a wide range, making it insensitive to most system fluctuations or modifications. These combined factors often result in a smaller BC fan to do the same job.

Another advantage is the BC’s low sound levels. The casing and optional inlet box has been tuned to reduce sound levels by at least 29 dB versus other exhausters delivering the same performance.

Hogger Type Fans

600 600 ESI

Hogger Type Fans for Custom Pneumatic System

We manufacture Hogger Type fans for a custom pneumatic system. Our Hogger Type industrial box fans meet the highest standards.

Features

  • 1500 to 67,000 cfm
  • 19″ to 73″ wheel diameter
  • Up to 30″ of water

The MacDonald Steel Hogger Type exhauster fans are made of heavy plate construction and are manufactured to our high quality standards. The entire fan case is made from 3/16″ thick HRS. In addition, exhausters No. 14 through 25 have 3/8″ T1 steel blades, while No. 29 and larger exhausters have 1/2″ T1 steel blades. This T1 steel has long been noted for its extreme toughness and abrasive resistance.

The exhauster blade/rotor is statically and dynamically balanced to operate smoothly throughout the rated speed range. There are two SKF pillow block adaptor mounting bearings. These pillow blocks are mounted on an especially heavy pedestal, which is an integral part of the exhauster.

The exhausters are equipped with safety guards and automatic motor bases when supplied as a package in a complete system. The exhausters are driven through a V-belt drive by an electric motor.

Air Type Fans for Custom Pneumatic System

We manufacture Air Type fans for a custom pneumatic system. Our Air Type industrial box fans meet the highest standards.

Features of Air Type Industrial Box Fans

  • 4000 to 100,000 cfm
  • 19” to 90” wheel diameter
  • Up to 30” of water

The MacDonald Steel Air type exhauster fan is manufactured of heavy plate construction. The entire fan case is of thick HRS plate and the exhauster blades are made of mild steel.
The scroll can be rotated at 22 1/2° increments to allow us to position the fan outlet in the direction necessary to suit the application.

The backward inclined high efficiency exhauster blade/rotor is statically and dynamically balanced to operate smoothly throughout the rated speed range. The fan is supplied with two SKF pillow block adapter mounted bearings and Dodge taper lock bushings.

Our exhausters are supplied with a high efficiency motor, motor base, drive sheaves, belts and safety guards when purchased as a fan package in a complete dust collection system. Our exhausters also come standard with a cleanout/access door in the scroll.
