Designed to allow watertight penetrations of metal roofs where products such as tube mounted fans are to be installed. Manufactured from EPDM rubber with aluminium inserts, the flashings are simple and quick to install.

Extension tubes are used in conjunction with Dektite Roof Flashing to allow roof mounting of circular fans and cowls (RCR Series Fans, MAD Cowls).
Manufactured from galvanised sheet steel with crimped ends and locating ridges for easy connection to fans and cowls. Tubes can easily be joined to accommodate steeper roof pitch angles. Powder coat colours are available as an option when ordering.

The VA series of speed controllers offers a comparatively low cost option for varying the flow, power consumption and sound levels of single phase fans with a current rating of up to 10 amps. Speed control ranges from 100% down to approximately 30%.
Notes
VA speed controllers are recommended for external rotor motor fans to ensure adequate cooling under speed control conditions. They should not be used to speed control fans with conventional foot or flange mount single phase motors other than models designated as being speed controllable. Refer to the wiring diagram packaged with the controller for specific instructions relating to installation. PSC (Permanent Split Capacitor) motors can be installed with three wire configuration to help minimise motor hum.
When more than one fan is to be controlled, the fans should be of the same type and capacity with the combined full load current not exceeding 85% of the controller FLC rating.

Run on timers are wired with a permanent active feed allowing the fan plugged into the unit to continue running for a pre-determined time period after the wall switch has been turned off. Ideal for use in toilets and bathrooms where continued extract ventilation after leaving the room is a practical solution.
