1. Product Characteristics

Muffler is a kind of main equipment which can prevent and control aerodynamic noise by blocking sound transmission and allowing airflow to pass through. The muffler series produced by our factory is suitable for the exhaust and exhaust noise elimination of boiler steam, heating furnace and baking furnace during start-up. It is also suitable for other gases (such as air superheated steam, saturated steam, nitrogen, oxygen, superfluous gas of air compressor, fan, etc.) to enter and exhaust noise reduction. The product has been proved by the users that the noise elimination effect is good and the noise reduction amount can reach more than 30dB (A), which fully conforms to the national hygienic standard of Industrial Enterprise Noise.

Description:

(1)The rated discharge flow of this series of mufflers is designed according to 1.3 Mpa. If the exhaust steam pressure is 0.8 Mp, the muffler should be selected one step larger than the discharge pipe diameter, and the exhaust steam pressure is 2.0 Mpa, and the muffler should be selected one step larger than the discharge pipe diameter.

(2) The silencing capacity of this series of mufflers can reach 35 dB (A).

(3) The standard of nozzle flange for muffler in this series is HG20592-1997, PN2.5.
