Safety Extra Low Voltage (SELV)

Designed for areas where a fan has to be fitted over or within zone 1 in a room containing a fixed bath or shower according to IEE wiring regulations (BS 7671), the VA100 SELV fan can be safely installed within the spray area. The fan is rated IPX7. Control is by mains safety isolating IP44 transformer unit with SELV output, which is sited away from any source of spray and out of reach of a person using a fixed bath or shower.

Vent-Axia SELV units have been independently tested in accordance with UK and European Safety Extra Low Voltage (SELV) and product requirements, and have as a result been granted BEAB approval based on CENELEC harmonised standards.

Models

Panel Model
For discharging into ventilation shafts. It can also be used with up to 3 metres of rigid ducting. Performance 75m³/h, FID sound level 31dB(A).

Window Model
The VA100 window kit is designed to fit VA100 units in windows and fixing surfaces up to 40mm thick. The four spacers supplied are placed on the inside of the glass to give minimum exterior projection.

Wall Model
The VA100 wall kit is a rigid telescopic wall sleeve for wall thicknesses from 255-360mm thick plus an outside grille set. For thinner walls the sleeves can be cut to fit.

Best Practice

Sensors and auto mode controllers save energy by only switching the ventilation units on when needed and when the room is occupied.

To meet IEE Regulations timer models should be isolated using a 3 pole isolator.

Typical Specification

Supply and install a VA100 SELV (Safety Extra Low Voltage) axial fan suitable for mounting in panels, walls or windows, with a thermally operated backdraught switch (SVL, SVXT, SVXH models), removable grille and fan running light.

When installed the fan should comply with the 16th Edition of IEE Regulations (BS7671, 2001) and on site guide for safety extra low voltage (SELV) operation. The transformer should be safety isolating to BS EN 60742. The fan should be rated to IPX7. The fan and controller should be BEAB approved.

The fan performance should meet the Building Regulation (Document F) requirements at 15 litres a second for bathrooms, and 6 l/s for toilets (15 minute timer overrun model for internal WC’s). The motor should be manufactured with self aligning sleeve bearings and be fitted with Standard Thermal Overload Protection (S.T.O.P.). The motor should be insulated to Class B and designed to operate on SELV 12v/1/50Hz.
