Transcription

1 NEW Acoustic In-Line Fans (ACQ) Acoustically treated housing, Class O rated, sandwich construction selected for maximum noise absorption Motors protected to IP44 Motor insulation Class B Maximum operating temperature 5 C Standard Thermal Overload Protection Aluzinc construction for internal or external mounting as standard All models speed controllable Manufacture controlled to BS EN 1S 91 Performance tested to ISO 581 The ACQ 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 at any angle, via drop rods or anti vibration mounts, ensuring a quick and easy solution to installation of the in-line acoustic fans. The access panel is easily removed for inspection. The full range of Acoustic fans manufactured from Aluzinc and as such are suitable for both internal and external mounting as standard. Ten models are available in sizes 1, 125, 15, 16, 2, 25, 315, 4 and 5, providing air volumes from.75m 3 /s to 1.69m 3 /s (27m 3 /h to 5,792 m 3 /h) at free air. Designed for pressures up to 55 Pa. Sound and Performance Tested to ISO581. Published db(a) figures are free field sound pressure levels at 3m with spherical propagation at a reference level of 2 x 1 5 Pa (2 micro-pascal). The inlet, outlet and breakout sound power level spectra figures are db with a reference of 1 12 Watts (1 pico-watt). Electrical The ACQ range is supplied with motors wound to suit a 23V/1ph/5Hz supply capacitor start and run. Quality Assurance Design and manufacture is in accordance with BS EN ISO 91. Motors At the heart of the range is a proven external rotor motor and backward curved impeller selected for low noise and high efficiency impeller assembly specially selected for its performance. The assembly is dynamically balanced to ISO 194. Motors are rated to IP44 according to BS EN Ball bearings are greased for life and allow the fan to run at any angle. Insulation is Class B (from -15 C to +5 C). All Acoustic fans are suitable for speed control with either an Electronic or Auto Transformer. An Auto Transformer is recommended to ensure minimum noise levels during speed control so eliminating any possibility of motor harmonic noise. Terminal Box An IP54 Terminal Box is supplied with all models with 2mm cable gland entry. 312
