The nitrogen machine equipment supplies monotonic primary air to the single-tuned filter of the air filter. The compressed air coming out of the compressor is not simple. This is because the air compressor itself has a rich oil, tighten the operation, there must be a certain smooth oil and compressed air mixed. Other natural gas itself is rich in some solid particles and water, when the direct use of this non-gas purification circuit in the pneumatic circuit, it will bring some shortcomings, pneumatic, pneumatic component damage, service life reduction components, reduced production capacity, and even composition.

The compressed air from the air source generally contains excessive water vapor and oil droplets, and also contains some solid impurities, such as rust, pipe sealant and sand particles, etc. These impurities will damage the sealing ring of the piston to a certain extent, and block the small exhaust holes on the components, which will shorten the service life of the components, and even lose the original function. The main function of the air filter is the separation of liquid water and liquid oil droplets in these compressed air, and the filtration of dust and some solid impurities in the air, but it will not remove water and oil in the gas phase.

The secondary air filtration process of the nitrogen machine equipment passes through the second filter - cotton fiber net. The direction and rotation of the air flow in the cotton fiber rope or adjacent air is changed, this cotton fiber rope, supported by stainless steel mesh, eddy currents, at the moment the air speeds up several times, when the tornado vortex center is the same, under vacuum conditions. Therefore, in the monotonous filter list the air filter does not remove water droplets is paired with the gas machine without any adverse effects. And remove the liquid droplets of impurities.

The structure of the air filter is from the compressed air flowing into the inlet to the guide plate, which is evenly distributed with the helical teeth of the fan blade, so that the compressed air flowing is forced to rotate along the tangential direction of the helical teeth, so that the liquid water, liquid oil and some large impurities mixed in the air will be separated under the powerful centrifugal force. It hits the wall and flows to the bottom of the glass. The compressed air that has been removed from the liquid water and liquid oil is filtered through a filter to remove the tiny solid particles, and then the clean compressed air is exported from the outlet. The umbrella-shaped water baffle will divide the water cup into two parts, and the lower part is not a pressure static zone, which can prevent the high-speed rotating air from sucking up the water and oil at the bottom of the cup. Finally, the water and oil gathered at the bottom of the cup will be discharged through the drainage. Remember that the air filter must be mounted downward in the vertical cup.

A monotone filter (stainless steel mesh) that condenses or lists the head elements within the air promotes the direction of the water and air to change. This change causes individual water droplets to bond to each other and collect in the condenser. The droplets gradually grow larger, large dust and other gravitational effects combine into a central storage room with water. Rich sewage along the movable bottom, through the active drainage valve drainage pool clean; A lot of water (about 95% of water) goes through the discharge process.

On the basis of this air monotone filtering principle, it can be obtained without impurities, oil droplets and droplets of compressed air clean and monotonous, nitrogen machine equipment repair machine and prevent freezing problems.
