At Workplace Saftey Management we are suppliers and installers of roof extraction ventilation fans for industrial applications.


Features & Benefits


Quality assurance

All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.

Tested to the very latest standards

WSM Roof units are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance)  meaning accurate, up to date information on performance and noise data that can be relied upon.


WSM Roof units are designed to be suitable for either curb or purlin mounting and can be mounted on flat or inclined roofs with a maximum pitch angle of 35°.

Design appeal

WSM Roof units are supplied as standard in goose wing grey, with the option of any other RAL colour to comply with the overall design, profile and colour scheme for a building.

Time Saving

Drop in silencers can be supplied which reduces installation time by fitting the silencers into the roof space rather than the ductwork – Less labour, less time and cost.

Ease of wiring

The electrical connection to the motor is made by an IP55 terminal box fitted to a 550mm flying lead from the units inlet side.


Motors have sealed for life bearings.

So if you're looking for someone to install your roof extraction fan, look no further call us on 0116 2742336 to find out more.
