SONIC – SEMI SERIES MUFFLER

SMI series unit are an absorptive type muffler are use to achieve moderate acoustics performance and where a very minimum back pressure allowed, since they are designed with straight trough bore. Muffler can be applied on all gas exhaust applications.

SONIC – SMC SERIES MUFFLER

SMC series are a combine performance of absorptive and reactive muffler (super critical muffler). These multi – chambers muffler will provide us with the highest attenuation of noise at all frequency, and give more than 30 dBA overall reduction. Muffler can be applied on all gas exhaust applications, where acousic and air flow require maximum insertionloss performance and high pressure application.

Muffler construction

All series of mufflers are manufactured from high quality carbon steel plate (SS400) and provide with a good welding technique, to ensure the product meets with the most demanding installation. Material infill for absorbing and covered wth heavy duty perporated steel sheet.

We also manufacture large size to meet your requirement.

Sonic Rectangular Duct Silencer

Sonic duct silencer (sound attenuator) provide predictable attenuation and known airflow pressure loss characteristic. The silencer is used to control the passage of noise along ventilation ducts and openings. Typical application includes building plant room (AHU, Generator room, etc), theatres, radio and television studios.

All units are rigidly constructed and consist of a galvanized sheet metal casing, containing a series of centre and side splitters (to reduce noise flanking) Acoustic splitters have a radiused nose (semicircular nose) or trigonal nose fairing to give a bellmouth entry to all airways resulting a low pressure drop and regeneration noise.
