Both the Xpelair PX9 & Xpelair PX12 are reversible making them ideal for ducted input systems in the hospitality industry. On PX9 & PX12 units a positive plug and socket assembly provides a means of isolation for service access without the safety risk of accidental disconnection. PX9 & PX12 models feature totally enclosed external rotor motors providing constant volume outputs, even in gusty external conditions. Pre-balanced sickle bladed impellers eliminate fan judder and ensure quiet trouble free operation. Sealed for life maintenance free bearings ensure suitability for running at any angle. Running costs are impressively low, and when not in use the silent electro-thermal shutter cassette closes silently against backdraughts. And cleaning has never been easier. The housing, shutter cassette and impeller are all removed in seconds.Ordering is straight-forward: simply check which model is most suited to your requirements.For assistance please call our sales office on 01304 215 575
