Heavy Duty H-Series

Our Durafan H-Series Heavy Duty fan range is ideally suited for medium to heavy duty applications due to its deep vane forward curved design. 

Our H-Series centrifugal fans are suited for medium to heavy duty applications due to their deep vane forward curved design.

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.

A sales engineer is always on hand to discuss your requirements and provide a full technical specification and quotation – just get in touch and tell us your application. We can advise and ensure you have the correct system for your project.

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 the requirement for resistance to chemical attack. We’ll ask you to provide full details at tender stage. Contact us to discuss your project at any point.


APMG Plastics also designs, manufactures and installs an extensive range of ductwork and vent fittings to complement our range of corrosion resistant extract fans. All pipework is manufactured to meet HVAC DW/154 Specification for Plastics Ductwork, which is the premier specification for PVC and PP-S ducting.
