The many different types of Fan Silencers used in industries and other ventilating applications are a major contributor to the noise issues, not only affecting worker health and safety but also environmental regulations.

The fans may be used individually as stand-alone applications or as components of equipment such as for example air handling units and dust collectors. Fans, which are mechanical rotating equipment, are a common source of noise in industries

Fans in industries usually become a source of significant noise problem leading the requirement of silencers.PK Engineering Fan Silencer will address this by

  • Regulating air flow by reducing loss of pressure in the silencer
  • Managing restrictions in space
  • Help attain environmental regulations for noise and health, safety requirements for industries
  • Using high quality components ensuring their durability

Fan Inlet Silencers & Fan Outlet Silencers

The Fan Inlet Silencers and the Fan Outlet Silencers are engineered to meet your exact noise reduction needs, with heavy gauge steel being used for industrial Fan Silencers and lighter gauges use for commercial Fan Silencers. Each Fan Silencers is engineered precisely for accuracy in their loss of pressure and velocity of airflow

Fan Silencers Applications

Generally Fan Silencers are used for Steel & Power plants, Chemical plants, Petrochemical refineries & Oil & Gas Plants with following applications

  • Forced draft Fan
  • Induced draft fan
  • Primary Air Fan
  • Secondary Air Fan
  • Axial Fans
  • Centrifugal type Fans

Input design Data Required

  • Air Flow Rate (Actual CMH)
  • Temperature (°C)
  • Maximum allowable pressure drop (mmwc)
  • Inlet / discharge Connection size of the Fan (Inches/ mm )
  • Existing noise frequency spectrum ( 63 Hz to 8 KHz) as per the table

Measured / predicted Noise level if available

Freq(HZ) 63 125 250 500 1K 2K 4K 8K Overall
Suction Noise SPL dB
