aptavent 4” Extractor Fans - comply with Building Regulation F1:1995

Vysal’s 4” extractor fans are probably the best performing fans available in the market today and offer outstanding value for money. They have been independently tested by Nemko for safety and by BSRIA for performance.

Aptavent fans were designed to meet the exacting requirements of the professional installer. The 4" extractor fans are of solid robust construction to facilitate quick and easy installation with no damage on site. No fiddly parts to deal with or lose. The 165 x 165 mm face plate provides plenty of space to get secure screw fixings into the wall without breaking through into the duct channel. The large 10 Amp terminal block allows easy access whilst making connections and accepts cables up to 2.5mm².

For the end user, the high efficiency six-bladed impeller provided class leading air movement in virtual silence. Independent performance testing by BSRIA confirmed that the only noise whilst running is attributable to the sound of air movement. The balanced motor and impeller ensure no vibration or rattles during operation.
