What is the working principle of primary, intermediate and high efficiency air filters?

2022-07-28 Page view : 8 views

Air filter: It is a device that traps dust from the gas-solid two-phase flow by the action of porous filter material and purifies the gas. It purifies the air with low dust content and sends it into the room to ensure the process requirements of clean rooms and the air cleanliness in general air-conditioned rooms.

SFFILTECH air filters are air filtration devices, generally used in clean rooms, clean plants, laboratories and clean rooms, or for dust control of electronic machinery and communication equipment, etc. SFFILTECH 10 Best air filters are available in primary, intermediate, high efficiency and sub-high efficiency models. Various models are available with different standards and efficiency of use.

In pneumatic technology, air filters, pressure reducing valves and oil mist collectors are called the three major pneumatic components. To get a variety of functions often these three air source processing components are assembled together in order, called pneumatic triplets. It is used to purify and filter the air source, reduce pressure and provide lubrication.

The installation order of the three major components is air filter, pressure reducing valve, oil mist in order of air inlet direction. The three parts are indispensable air source devices in most pneumatic systems, installed near the air-using equipment, is the final guarantee of compressed air quality, its design and installation, in addition to ensuring the quality of the three parts themselves, but also consider space-saving, easy to operate and install, can be arbitrarily combined and other factors.

How the filter filters the air

General air purification equipment filtering air is roughly divided into the following methods and steps.

1、Multiple filters; prevent dust and germs in the air from entering the room multiple activated carbon filters effectively intercept dust and germs, filter the air and ensure that the air entering the room is clean.

2、titanium oxide to kill poison; degradation of indoor air pollution of formaldehyde, benzene and other organic toxic gases, nanoscale titanium dioxide activated by ultraviolet light, to filter the air to effectively degrade the air of formaldehyde, benzene and other organic toxic gases radioactive pollution.

3、anion oxygenation; increase the oxygen in the indoor air to the right amount and keep the content stable, anion generator to indoor air oxygenation, to ensure that the air into the home to maintain a sufficient amount of oxygen, vibrant, to strengthen the filtered air.

4、PTC ceramic heating; heating indoor air to a comfortable temperature PTC ceramic heater to the winter into the new indoor air for auxiliary preheating, appropriate to increase the temperature of the room, thus filtering air, so that the home warm and comfortable.

5、ultraviolet sterilization; strong to kill the air in the epidemic virus bacteria, ultraviolet light source with strong to kill the air in the epidemic virus bacteria, so that people away from the source of infection, to filter the air and care for the health of the whole family. The filter is an indispensable device on the pipeline for transporting medium, usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level valve or other equipment to eliminate the impurities in the medium to protect the normal use of the valve and equipment. When the fluid enters the filter cartridge with certain specifications, the impurities are blocked, and the clean filtrate is discharged from the filter outlet.

SFILTECH believes that significant progress has now been made in filter performance, the most important of which is the removal of the divider, i.e. the development of seperate-free filters. The spacerless filter not only eliminates the risk of damage to the filter media by the spacer, but also effectively increases the filter area, improves the overshake efficiency, and reduces the airflow resistance, thus reducing energy consumption. In addition, the air filter has made great progress in high temperature resistance, corrosion resistance, as well as waterproof and anti-bacteria, to meet some special needs.
