Backwards Inclined Plastic Fan

The BI-Series Backward Inclined Centrifugal Fan is a hard-wearing industrial fan ideally suited to light or medium-duty applications.

BI-Series Plastic Fans

Our extract fans are designed and manufactured at our Manchester-based factory, where our highly skilled plastic fabricators deliver high-quality products at competitive prices.

Bifurcated Fan Configuratiton

The angle and number of blades in a bifurcated fan will depend on the duty point of the fan. Our expert team of sales engineers can advise which impeller configuration will most efficiently achieve the required volume and pressure for your application.

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

The materials of construction for each fan are chosen according to the fan’s application and the requirement for resistance to chemical attack. We’ll ask you to provide full details at tender stage.

FAQs

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.
