What Is An Air Filter？

High quality air filter refers to the air filter device, generally used in clean workshop, clean workshop, laboratory and clean room, or used in electronic, mechanical and communication equipment dustproof. There are primary effect filter, medium effect filter, high efficiency filter and sub-high efficiency and other models. Various models have different standards and performance.
In pneumatic technology, high quality air filter, pressure relief valve and oil mist device called pneumatic three. In order to obtain a variety of functions, these three air source processing components are often assembled together in sequence, which is called pneumatic triconnector. Used for air source purification, filtration, decompression and lubrication.
An effective air filter is a device that captures dust from gas-solid two-phase flow through porous filter materials and enables gas purification. It sends the air with low dust content into the room after purification, so as to ensure the technological requirements of clean rooms and the air cleanliness in general air conditioning rooms.

The installation sequence of the three parts is high quality air filter, pressure relief valve and oil mist device according to the inlet direction. The three parts are indispensable air source devices in most pneumatic systems, installed near the gas equipment, is the last guarantee of compressed air quality, its design and installation, in addition to ensuring the quality of the three parts themselves, but also consider saving space, convenient operation and installation, can be arbitrarily combined and other factors.
The compressed air coming out of the air source contains excessive water vapor and oil droplets, as well as solid impurities, such as rust, sand, pipe sealant, etc., which will damage the piston sealing ring, plug the small exhaust holes on the components, shorten the service life of the components or make them ineffective. The role of effective air filter is to separate liquid water and liquid oil droplets in compressed air, and filter out dust and solid impurities in the air, but can not remove gaseous water and oil.

High quality air filter is to obtain clean air that can meet the standard. General ventilation filter is to capture and adsorb dust particles of different particle sizes in the air, so as to improve air quality. Chemical filter can mainly adsorb odor in addition to dust adsorption, which is usually used in bio-pharmaceutical, hospital, airport terminal, human settlement environment and other places. The effective air filter for general ventilation is widely used, microelectronics industry, painting industry, food and beverage industry and so on. In other words, the filter is only a means to achieve the goal of cleanliness.
