3/4″ NPT Pneumatic Air Exhaust Muffler Silencer for Desiccant Air Dryer

Description

The XY-07 air exhaust muffler has wide application for noise reduction in a variety of equipments, such as air compressors, desiccant dryers, vacuum pumps, pneumatic diaphragm pumps, etc. The air dryer muffler uses unique materials and structure. It has a good noise reduction effect. Besides the resistance is small. The exhaust flow is large.So Air muffler silencers are ideal spare parts for compressed air dryers.

The technical specification of air muffler silencer:

The features of compressed air dryer silencer:

1. Firstly, the upper and lower end caps use aluminum alloy. In the middle is the galvanized mesh. Therefore, it is durable and not easy to rust.

2. Secondly, the inner white part is sound-absorbing cotton, and the red part is sound-proof paper. The multilayer glass fiber cotton has a compact structure. So the noise reduction effect is more significant than that of PP cotton.

3. Thirdly, the threaded port of air exhaust muffler has a built-in gasket, which has a good sealing effect.

4. In addition, the air muffler silencer uses a thick spring. Then it has better shock absorption effect.

5. Finally, the air dryer muffler has ultra-low back pressure and high noise reduction effect, and large displacement. The sound attenuation reaches more than 30dBA.

How dose air exhaust muffler work?

Its working principle is to reduce noise by reducing exhaust speed and flow. Because high pressure or compressed air can release potential energy and kinetic energy in a much larger space than the exhaust port. In addition, sound energy is converted into heat energy through sound-absorbing materials. So as to achieve the effect of noise reduction.

This product is a new type of exhaust air muffler silencer. The main material is ultra-fine sound-absorbing glass wool. It has good sound absorption frequency and high temperature resistance. Through the air dryer muffler, it can reduce the noise by more than 30 decibels.

Why need the air dryer muffler?

The desiccant dryer is a commonly used compressed air drying equipment. During the alternate regeneration process of the two adsorption towers of the dryer, it exhausts air to the outside. At the same time, it will produce high-decibel noise during the exhaust process. This will affect the factory working environment. So it needs the air exhaust muffler silencer.

The regeneration air has a certain pressure when it is discharged. Moreover, the exhaust speed is fast, which will cause air vibration and produce strong exhaust noise. Generally, it can reach 80～110dB. According to relevant regulations, when the exhaust noise is greater than 75dB, it needs noise reduction measures.

FAQ

Q1: How to maintain the air muffler silencer?

A1: In the compressed air dryer, due to the large amount of dust and moisture in the regeneration exhaust gas, condensation water will accumulate. So it can easily cause the air dryer muffler to be blocked. Therefore, the working conditions of air exhaust muffler are very harsh. It is a fragile part in the desiccant air dryer.

Once the air muffler silencer is blocked, the regeneration exhaust gas will lose its discharge channel. So it will make the internal pressure of the dryer continue to rise. Then the regeneration process will not proceed. In severe cases, it can also cause the air dryer muffler to burst. Therefore, the air muffler is the focus of the daily maintenance of the desiccant dryer.

Q2: Why the air dryer muffler keeps exhausting?

A2: This problem has nothing to do with air muffler silencer. The main reason is that the solenoid valve or control valve of Tower A or Tower B is out of order. Then it needs to repair or replace the valves.

Q3: Why does the air exhaust muffler of the adsorption dryer emit water?

A3: In fact, this is a normal phenomenon. Desiccant air dryers generally have two towers. One is for drying and the other is for regeneration. They switch each other. Regeneration means that a part of the dried air enters the regeneration tower to absorb the moisture inside. Then discharge the water from the air muffler silencer through the control of the solenoid valve.

These water is the moisture in the compressed air. After the water is absorbed by the desiccant beads, they are discharged from the air exhaust muffler.

Q4: What specifications of the muffler do you have?

A4: In addition to 3/4″ silencers, we also have sizes, such as 1/2″, 1, 1 1/4″, 1 1/2″, 2″, etc. And besides the normal pressure air dryer silencer, we can also customize high pressure air exhaust muffler.
