The ILHT range of direct drive in-line fans is designed to withstand the extract of air streams (only air stream within fan enclosure) of 400°C for a minimum period of two hours. All models are supplied with the motor located out of the air stream mounted on the external face of the casing.

All models are certified for 400°C/2hr for the purpose of extracting hot smoke in the case of a fire. The ILHT series of centrifugal in-line fans offers a truly flexible solution to installation whereby the configuration of both the inlet and discharge ports can be changed by simply altering the positioning of casing side panels.
