ATQ40014D – Acoustic Twin Fan – 400mm – Vent Axia
Vent-Axia ATQ fans feature an acoustic foam of dual density sandwich construction specially selected for maximum sound absorption and quiet operation. The housing is designed to be as compact as possible for concealed false ceiling applications. Manufactured in Aluzinc sheet metal, with integral anchorage points to allow the fan to be suspended horizontally via drop rods or anti vibration mounts, ensuring a quick and easy solution to installation. The access panel is easily removed for inspection. Individual gravity operated shutters prevent air from passing through the unit during shut down periods.
The full range of acoustic fans are manufactured from Aluzinc and as such are suitable for both internal and external mounting as standard.
Ten models are available in sizes 100, 125, 150, 160, 200, 250, 315, and 400, providing air volumes from 0.08m3/s to 1.27m3/s (288m3/h to 4572m3/h) at free air. Designed for pressures up to 550 Pa.
Motors
At the heart of the range is a proven external rotor motor and high efficiency backward curved impeller specially selected for its performance. The assembly is dynamically balanced to ISO 1940. Motors are rated to IP44 according to BS EN 60529. Ball bearings are greased for life and allow the fan to run at any angle. Insulation is Class ‘B’ (from -15°C to +50°C).
All Acoustic fans are suitable for speed control, an Auto Transformer is recommended to ensure minimum noise levels during speed control so eliminating any possibility of motor harmonic noise.
Auto-changeover control is available from the Trackmaster range of controls providing auto changeover control on fan failure and duty sharing options. All controls provide BMS operation via volt free contacts and the option for remote indication.
