High Temperature Fans

Frequently asked questions

What temperature can these fans handle?

All the fans in this range are rated for extract air up to 120°C. Check the product page for the exact rating, duty and any limits on continuous running at high temperature.

Can I use these for commercial kitchen extract?

Yes, they are built for it: insulated, double skinned box casings, motors positioned for hot air duty and access for cleaning. The Slim Qube keeps its motor outside the airstream, away from grease and heat. Kitchen extract systems also need grease filtration at the canopy and regular duct cleaning. See also our commercial kitchen extractor fans.

AC or EC motor?

AC fans are lower cost and are speed controlled with an inverter or a stepped controller. EC fans use less energy, run quieter at reduced speed and are fully variable through a 0-10V signal or potentiometer. Use the buttons above the products to filter by motor.

Single phase or three phase?

The KBT 160 and the single phase Qube EC models run from a standard 230V supply. The Slim Qube and the larger Qube models are three phase. The Slim Qube three phase AC models can be run from a single phase supply through a suitable Eltadrive inverter. Check the supply available before choosing.

Are high temperature fans the same as smoke extract fans?

No. A high temperature rating means the fan can run continuously with hot air. Smoke extract fans are tested and certified to run at much higher temperatures for a set time in a fire, which these fans are not. Do not use them for a smoke control system.

How do I size a high temperature fan?

Size from the airflow the canopy or process needs and the resistance of the ductwork, filters and any attenuation. Send us the canopy size or airflow, the duct layout and the supply available, and we will select a fan.
