SOUND ATTENUATORS
Aircoustics ARSA/ ACSA/ARPL/ARBSA are the range of sound attenuators designed for Rectangular/ Circular/ Pack less/ Bend type respectively. The product has been developed to meet today’s high requirements for sound attenuation and is especially suitable for use in duct systems. Aircoustics have optimized the sound attenuators with regards to the acoustic properties of the sound- attenuating materials/ thickness & length of the splitters plus width of the slots and cleanability. Aircoustics can always offer the best sound attenuation and lowest pressure drop** according to customer requirements.
Circular attenuators are available with and without pod design.
The splitters are aerodynamically shaped for least pressure drop effect on airflow. Hygienic silencers are available with specification complying to VDI 6022. Inspection hatch can be requested if needed. Optional slip & drive connections, mounting feet and drainage plug can be requested.
RANGE/ SERIES
ARSA
- ARSA- SRL certified rectangular attenuators:
- Low pressure drops due to tapered splitter.
- It reduces inherent sound generation in the system due to lower air velocities and pressure setting.
- Good Aerodynamics characteristics
- Washable surface
- Sound absorbing material can resist high velocities which is covered with perforated sheet
ACSA, ACSA-P, ACSA-1
- ACSA– SRL certified Circular Attenuators without Pod.
- ACSA-P Available with center Pod for extra high attenuation.
- ACSA-1 is with flanged connections and are drilled with threaded for metric screws.
- Fire resistant insulation is E30 standard.
- WIDE range and high attenuation
- Aerodynamic shaped center body
- Connection diameter from 100 to 2000 mm and available with rubber seals.
- VERY low pressure drop**
- Sound absorbing material can resist high velocities which is covered with perforated sheet
ARPL
- ARPL– Pack less attenuators
- Fibrous acoustic material out of the air stream.
- Easy to Sanitize. Suitable for corrosive areas.
- Low-pressure drop-in med velocity i.e., 2000 fpm or less. For low or high velocity systems** please contact our sales office for design.
ARBSA
- ARBSA- SRL certified Bend type attenuators
- Low pressure drops due to tapered splitter
- It reduces inherent sound generation in the system due to lower air velocities and pressure setting
- Aerodynamically shaped splitters
MATERIAL
- Standard manufacturing is in GI sheet; however, special material and design available in Aluminum module and stainless steel.
