HVAC Rectangular Sound Attenuators Machine
HVAC Sound Attenuators | Noise Reduction for HVAC Duct Systems ...
The sound attenuators are designed to combat noise problems. All fans/impellers used in air conditioning system produce noise, relevant to the amount of work they do to move the air, much of the noise is generated by the fluctuations of radiated pressure and these pressure waves are distributed approximately equally in all directions, causing “duct born noise “and break out”.
The HVAC Rectangular Sound Attenuators by our roll former is just the Noise Reduction Solution for HVAC Duct Systems.
The sound attenuators have been tested for dynamic insertion loss, pressure drop and self-generated noise in accordance with ASTM Standard E477 test standards.
Various sizes rectangular sound attenuators can be produced by machine, after simple adjustment, by hand wheel or servo motor control, to match most any size of duct in the present world market.
Technology specification - HVAC Rectangular Sound Attenuators Production Line
The Rectangular sound attenuators Casing production Line is designed according to 0.5-0..8mm thickness GI Steel normally. The whole Damper making machine is consisted of uncoiler,, leveler and hydraulic press, strip feeding table, roll form machine, hydraulic cutter, run out table, hydraulic system, electrical control system, etc.
Technology process is as following
Coil unwinding → sheet guiding → leveling → punching holes moulds→ cold forming→ cut to length → receiving Frame → hand folded into a frame

HVAC Rectangular Silencer Sound Attenuators
Ventilation Silencers is a device that uses air absorption, reflection, interference and other principles to reduce airflow noise in ventilation and air conditioning systems. Resistive sound absorption and noise reduction effect with good effect on medium and high frequency broadband characteristics. According to the different principles of noise elimination, it can be divided into resistive, resistant, resonant and composite.
