BI-Series Backward Inclined Centrifugal Fan

Our extract fans are designed and manufactured at our Manchester-based factory. From here our highly skilled team of plastic fabricators delivers high quality products at competitive prices.


We offer a range of 11 standard sizes of high efficiency backward inclined centrifugal extract fans.

Fan Casing – Fan casing manufactured from polypropylene or PVC and glass fibre reinforcement for higher pressure applications.

Impeller – Backward inclined centrifugal fabricated from polypropylene.

Pedestal – Standard rolled steel sections with hot dipped galvanised finish | Motors – IEC standard motors to IP55 which can be upgraded to suit the 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.

Our BI-Series backward inclined centrifugal fan range has proved to be a popular international fume extraction solution. We can apply a GRP (glass fibre reinforced plastic) coating to our fans for even greater resilience. Read our case study here.

We match the materials of construction for each fan according to its application and 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 designs, manufactures and installs an extensive range of ductwork and vent fittings. We fabricate these in-house to complement our ranges of corrosion resistant extract fans. We manufacture our pipework to meet HVAC DW/154 Specification for Plastics Ductwork. This is the premier specification for PVC and PP-S ducting.
