Fans - PVEs range of impulse fan casings are manufactured from 3mm mild steel, roll formed and automatically welded. Our special jointing arrangement means that no flanges are required to fix attenuators ensuring a lower profile unit and greater traffic freedom within the car park.

Impellers - PVE impulse fans are all fitted with adjustable pitch impellers of true aerofoil shape. Blades are manufactured from high quality pressure die cast aluminium alloy (LM6). All impeller blades are factory set to ensure optimum aerodynamic performance and assembled impellers have blades locked and pinned as an extra safeguard under high temperature conditions.

Motors - For ease of maintenance and easy replacement worldwide PVE use totally enclosed metric frame motors to IP 55. Standard high temperature motors designed and tested for the specific application. Our motors are designed especially for use under normal day-to-day ventilation and will if required run continually in this mode switching to smoke clearance mode when conditions within the parking facility dictate for use at 200°C or 300°C for set length of times.

Motors are of cast iron frame construction with windings of class H insulation. Temperature resistant flying leads are brought out of the casing and connected prior to testing and despatch to a high temperature isolator featuring a lockable On / Off feature.
