Precision filters (also called safety filters), the shell of the cylinder is generally made of stainless steel, and the inside uses tubular filter elements such as PP meltblown, wire fired, pleated, titanium filters, activated carbon filters, etc. increase. As filter elements for different filter media, the design process selects different filter elements to meet wastewater quality requirements. It is used for solid-liquid separation of various suspensions, high environmental requirements, and chemical filtration with high filtration accuracy. It has a wide range of applications and is suitable for medical, food, chemical industry, environmental protection, water treatment and other industrial fields.
2. Equipment performance

(2) Small filtration resistance, large flux, strong pollution interception ability and long service life;
(3) The filter element material has high cleanliness and no pollution to the filter medium;
(4) Resistance to acid, alkali and other chemical solvents;
(5) High strength, high temperature resistance, and the filter element is not easily deformed;
(6) Low price, low operating cost, easy to clean, and replaceable filter element.

Precision filters use multiple layers of different filter media, such as borosilicate fiber layers, glass fiber layers, activated carbon fiber layers, multi-layer non-woven fabric layers, and stainless steel mesh layers, to achieve high-precision filtration quality. This is the only way to achieve quality air free of oil and contaminants.
The C main line filter removes a large amount of liquid and solid particles of 3 μm or larger, and achieves a low residual oil content of only 5 ppm with a small amount of water, dust, and oil mist. Used as general protection after the rear air compressor cooler and before other filters. It functions as a pretreatment device before the cold dryer.
T-air line filters filter out liquid and solid particles down to 1 μm in size, achieve residual oil content as low as 0.5 ppm, and contain traces of moisture, dust, and oil mist. Used for preprocessing before the A-level filter. Air quality can be further improved after cold dryers and suction dryers.
The ultra-efficient oil removal filter filters 0.01μm liquid and solid particles, achieves a minimum residual oil content of only 0.001ppm, and removes almost all water, dust and oil. It acts as a protection before use in H-class filters and suction dryers and ensures that the air is oil-free after refrigeration dryers.
The H activated carbon micro oil mist filter removes small oil mists as small as 0.01 μm and hydrocarbons for the lowest residual oil content of only 0.003 ppm. It does not contain water, dust, or oil, and is tasteless and odorless. Serves as a final filter for some units that need to use high quality, high quality air, such as: B. Food industry, breathing, aseptic packaging, etc.
Fourth, the role of precision filters:
A precision filter is often installed after the pressure filter to remove particulates in the liquid.
