Vent-Axia ATQ fans feature a 50mm acoustic lined sound controlled housing rated Class 'O'. The housing is designed to be as compact as possible for concealed false ceiling applications. Manufactured in galvanised sheet metal, with integral anchorage points to allow the fan to be suspended at any angle, via drop rods or anti vibration mounts, ensuring a quick and easy solution to installation. The access panel is easily removed for inspection using the four quick release catches provided. Individual gravity operated shutters prevent air from passing through the unit during shut down periods.
Acoustic Twin fans are also available, finished with optional C.R.P (Chlorinated Rubber Paint), ensuring the unit is fully weatherproofed and suitable for external mounting. All weatherproofed units are manufactured to order. Note the standard product codes are suffixed with ‘WP’ eg ATQ100-12CWP.
Ten models are available in sizes 100, 125, 150, 160, 200, 250, 315, 400 and 500, providing air volumes from 0.057m³/s to 1.40m³/s (205m³/h to 5040m³/h) at free air. Designed for pressures up to 550 Pa.
At the heart of the range is a proven 230V/1/50Hz external rotor motor and forward curved galvanised impeller assembly. 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).
The size 500 utilizes an internal rotor motor with Class B insulation (from - 15°C to +40°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.
An IP54 Terminal Box is supplied with all models with 20mm cable gland entry.
