1. Product description

Wkr-50/100 silencing elbow is a national standard product. Suitable for air conditioning and ventilation system with limited pipe length and limited installation of straight pipe muffler. The thickness of sound absorption layer of the silencing elbow is 50 mm and 100mm respectively. WKR50≥10dB(A),WKR100≥12dB(A).

Muffler elbow is the elbow lined with sound absorbing material, which has a significant attenuation effect on sound waves. Insert an Angle muffler elbow into the rectangular section pipe and lay sound absorbing gaskets on both sides of the elbow. The length is 2 to 4lz (lz is the characteristic width of the pipe section). Then the insertion loss at high frequency is 10dB higher than that of the liner straight pipe of the same length. The so-called high frequency, that is, the frequency above the pipeline cutoff frequency. Generally installed in the feed, return air port position.
