BCB Filter Element 21FC1421-160x800/6

The fine filter element of the online coalescing and separating oil filter device can filter out impurities in the oil. The filter material: glass fiber filter material, deep-seated dirt, high filtration efficiency.

Due to frictional resistance and viscous resistance, part of the sound energy is converted into heat energy and lost, achieving the effect of silencing. The resistive series muffler has a good noise reduction effect on the noise in the middle and high frequency range. Generally, materials with sound absorption coefficient α>0.2 are called sound-absorbing materials. Sound-absorbing materials are not only necessary materials for sound absorption and noise reduction, but also indispensable for the manufacture of sound insulation covers, resistive mufflers or impedance composite mufflers. Porous sound-absorbing materials have better sound-absorbing effects and are widely used sound-absorbing materials. It is divided into three types: fiber type, foam type and particle type.

Fiber-type porous sound-absorbing materials include glass fiber, mineral wool, felt, glycoside fiber, wood wool board and so on. Foam-type sound-absorbing materials include polyurethane foam and so on. Granular sound-absorbing materials include expanded perlite and microporous sound-absorbing bricks. The design principle of the resistive series muffler is: when sound waves enter the muffler, it will cause the air and fiber in the porous material in the resistive muffler to vibrate due to frictional resistance and viscous resistance.
