Fans - Industrial Exhaust Fans: Wheel Types

Industrial Exhaust Fan Wheels: There are four basic wheel types available with N. R. Murphy exhaust fans: EH for heavy duty material handling; EM-1 and EH-1 for light duty material handling; and EA-1 for air handling. Each wheel design has different characteristics for different applications.

The following descriptions should help you choose the proper wheel for your needs. If you have any questions or problems, please contact our fan experts for advice.

Heavy Material Handling - Wheel EH:

This open wheel is designed for most industrial material handling requirements. It is accurately fabricated from extra heavy steel plate to withstand severe shock and abrasion in high material volume applications.

Typical applications would be for handling air containing small wood blocks, knots, silage, (paper trim incorporating a nose cone into the design) or similar materials.

The EHL wheel, of the same design as the EH-1, is constructed for standard industrial material handling requirements.

Wheel EM-1

Material Handling - Wheel EM-1:

This wheel is similar to the open design EH, but has a back plate to prevent long, fibrous or stringy materials like wood shavings from wrapping around the blades. Wheel EM-1 with slightly higher efficiency than the EH design is widely used for sawdust chips or similar material. The back plate and individual blade supports add extra rigidity and strength to the wheel.

Air Handling - Wheel EA-1:

This open wheel is designed for most industrial material handling requirements. It is accurately fabricated from extra heavy steel plate to withstand severe shock and abrasion in high material volume applications.

The air handling wheel EA-1 is ideal for the efficient handling of relatively clean air. It features a backward inclined, radial tipped design with a coned shroud and back plate for added rigidity and strength. The air flow is guided by this controlled inlet clearance. Wheel EA-1 has the highest efficiency of our four wheel designs.

This wheel is used extensively for pulling air through filters or separators. It should not be used for handling materials.
