Vent-Axia promotes the strong, silent type
Discreet and quiet ventilation — Vent-Axia’s Centrif Plus.
Vent-Axia’s Centrif Plus range of ventilation fans meet the requirements of Part F of the Building Regulations with low sound levels. The larger Centrif 250 models have sound levels of 40 dB(A) at high speed down to 25 dB(A). They have the same grille-free fascia as the Solo Plus range and are available with timer and humidistat options and 2-speed, pull-cord or remote-switch operation. All Centrif Plus models have trickle-speed running as standard. A telescopic wall-fitting kit slides into a 115 mm-diameter core-cut hole. Ceiling installations are ducted either through a soffit outlet or to a roof cowl assembly. Electrical protection is to IP44.
