Heavy Duty Plastic Fan

From our extensive range of plastic fans, our H-Series Heavy Duty plastic fans are best suited for medium to heavy-duty applications.

Manufactured by our time-served plastic fabricators in our Manchester factory they provide an excellent extraction solution for the industrial sector. These centrifugal fans offer a multitude of rotational discharge angles to accommodate more intricate duct systems and allow improved system flow.


The H-series centrifugal fans are available as a compact direct drive arrangement, controlled via an inverter for energy saving, or the optional vee belt drive version.

Manufactured from polypropylene as standard, additional stiffening and glass fibre reinforcement can be added to handle higher fan speeds and system resistance.


The H-series centrifugal heavy duty fan range is available in 10 standard sizes.

  • Fan Casing – Fabricated from polypropylene as standard, also available in PVC for special applications. Glass fibre reinforcement can be added to the fan case for higher pressure applications.
  • Impeller – Forward curved multivane, fabricated from polypropylene as standard, also available in PVC for special applications.
  • Pedestal – Standard rolled steel sections with hot dipped galvanised finish.
  • Motors – IEC standard motors to IP55 which can be upgraded to suit any specification.
  • Bearings – SKF or equal, double row, self aligning ball
  • Drives – Fenner or equal
  • Fixings – Stainless steel throughout.
  • Anti-vibration mountings – AVA or equal, rubber in aluminium with option of spring mounts
  • Drive Arrangement – Standard V belt or direct driven.

The materials of construction are chosen according to their application and resistance to chemical attack. We’ll ask you to provide full details at tender stage. 


Please see below the most common question regarding our plastic fans. Contact our friendly team if you can’t find the answer you need.

Are single phase motors suitable for plastic fan operation?

We do not offer single-phase motors for our plastic fans. This is for the following reasons:

  • Single-phase motors must operate above 75% of full load current to limit the excess power dissipating as heat. This heat causes the motor to burn out.  
  • Because the design and actual duties achieved following installation are seldom the same, we use our experience in air movement to mitigate any potential problems by sizing fan motors at the top end of their capability. We base our calculations on the fan duty specified by the client.
  • Short intermittent use of a single-phase motor may be acceptable as the heat rise within the motor would be limited, and the unit would cool down between periods of use. However, we do not recommend or supply this type of motor for any fan applications.

Should a single-phase motor still be requested, we would require this to be free-issued for us to fit. We would be unable to provide a warranty on the fan unit due to the potential issues that may be experienced.

APMG will always recommend three-phase motors controlled using a single-phase input/three-phase output inverter.
