Asia-Pacific sales impedance composite muffler micro-perforated muffler complete range to meet customer needs muffler T701-6 Impedance complex muffler The muffler is one of the standard pipe muffler, in order to change the wooden frame deformation affecting the quality problems, the company re-designed steel structure absorption between the sound chip and the inner tube and the outer tube cross section consists of an expansion chamber, a rectangular enclosure, the IF and high frequency has a larger muffler, can be used to reduce air-conditioning and ventilation systems, the low pressure turbine noise. Ventilation air volume 2000-6000m3 / h, for no corrosive effect on metal surfaces and dust-free applications, such as a corrosive effect on metal surfaces can also special order, but it should be noted when ordering. WX-type micro-perforated muffler WX-type micro-perforated muffler is a wideband noise suppression means an all-metal structure is assembled from stainless steel plate, galvanized sheet or aluminum mechanical punching of micro-perforated panels together. As a result of different rates and different perforated rear chamber double orifice, so have a good muffling effect in a wide range of audio, has been tested and proven, this muffler (L = 1.8 m) at low frequencies, elimination the volume of 12-26db, when the IF, muffler amount 20-25db (wind speed at 10-15m / s when). The muffler resistance loss is very small. Tested in wind speed 9-11m / s, the resistance loss for 7-29Pa. YZBX type split plate muffler muffler split a plate belonging resistive muffler pipes, ventilation pipes are mainly used silencers, but also can be used in the air conditioner. Split plate muffler effective length of each section of 900mm, the room is adjusted according to the needs and characteristics of the sound spectrum needs and the amount of wind, air duct section 2-3 choice, the choice of the return air duct section 1-2, the best results. Far away from the fan outlet muffler, avoid high-speed airflow, preferably located in the duct end, the suspension should be added in isolation measures to prevent the transmission of solid noise. YKZF Expansionary impedance composite muffler ★ order to focus on resistive and muffler bit, so the range from low frequency to high frequency noise have been better controlled, the use of mutation within the muffler pipe cross-section, the role of the expansion chamber and outside the chamber to Both forms of muffling structure together, they constitute a broad frequency muffler. ★ We combine engineering practice for T701-6 type made further improvements, in order to change the wooden frame deformation affecting the quality, the company re-design of galvanized steel structure, rectangular enclosure, flange galvanized improve handling and mechanical punching product corrosion resistance and connection efficiency. Applies to 4-72,9-16,9-26 fan outlet muffler. ★ has a large muffler for high-frequency effects, can be used to reduce air conditioning and ventilation systems, the low pressure turbine noise. Ventilation air volume 2000-6000m3 / h, the wind speed is generally 6-8m / s is appropriate, should not exceed 8m / s. Muffler low frequency of 10-15dB / m, IF for 15-25aB / m, the high frequency of 25-30dB / m.
