Features & Benefits
All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.
Tested to the very latest standards
SSF units are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance) at Elta Fans own test facility, meaning accurate, up to date information on performance and noise data that can be relied upon.
SSF 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°.
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.
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.
