Precision filter (also known as security filter ), the shell of the cylinder is generally made of stainless steel, and the interior uses PP melt blown, wire-fired, folded, titanium filter, activated carbon filter and other tubular filter elements as filter elements. According to different filter media and The design process selects different filter elements to meet the requirements of effluent water quality. With the continuous development of the filtration industry, more and more industries and companies have used precision filters, and more and more companies have joined the precision filter industry.
Product Categories
According to the different process water requirements of various industries and the different raw water quality, the whole process water processor can be customized to meet the water standard.
Precision filter process
The precision filter is equipped with a precision filter element. The filter element generally adopts an external pressure type. The water passes through the small micropores of the filter element and enters the center tube of the filter element. The micropores trap small impurities in the water. The precision of the market filter element is 100um, 50um, 30um, 20um, 10um, 5um, 1um, 0.45um, 0.22um, 0.1um.
Common filter types and characteristics
1. Melt blown filter element, features: low price, pore size is generally above 3um, large market usage.
2. Features of the wire wound filter element: low price, the pore size is generally above 3um, and it can be reused after cleaning.
3. Features of the folded filter element: high precision and high cost, generally used in the subsequent treatment of pure water.
Application occasion

Pharmaceutical and biological engineering industries: infusion (LVP and SVP) pharmaceutical water, biological products plasma serum, various pharmaceutical intermediates, pharmaceutical raw materials, solvent filtration, CIP filtration, fermentation tank air intake and exhaust gas sterilization filtration.
6. Automobile manufacturing industry: electrophoresis paint, topcoat, ultrafiltration water, pre-treatment liquid, spray water for the whole vehicle, coolant for manufacturing engine crankshaft, industrial gas for spray painting and gas purification in spray booth.
7. Electronics and electroplating industry: liquid crystal display, photoetching machine, optical disc, copper foil, integrated circuit and other microelectronics and electronic products manufacturing process of various chemicals and treatment, electroplating solution, process gas purification and gas filtration in the purification room.
8. Food, beverage and wine industry: process purification and aseptic manufacturing of food additives such as wine, rice wine, white wine, beer, fruit wine, sake, juice, tea beverage, soy milk, dairy products, bottled water, edible oil, vinegar, monosodium glutamate, etc. deal with.
Precautions for precision filter
1. The filters are combined and configured according to the principle of "first coarse and then fine", and the order cannot be reversed.
2. The actual flow, pressure and temperature of the compressed air passing through the filter cannot exceed the value specified on the nameplate.
3. When installing, pay attention to distinguish the inlet and outlet positions of the filter.
4. The filter is installed vertically. Leave a certain height above the ground for easy replacement of the filter element.
5. The filtering effect is obviously deteriorated or the pressure difference exceeds 0.07MPa, the filter element should be replaced
6. The inlet temperature of the filter does not exceed 66°C.
