What are the types of nylon mesh filter?
(1) The structure and characteristics of the plate primary filter:
The main components of the plate-type primary filter are filter cloth, iron mesh and outer frame. The filter cloth of the plate-type primary air filter is generally a high-flux and low-resistance chemical fiber cloth, and the outer frame is generally a paper, galvanized iron frame, stainless steel, aluminum alloy, etc.
The characteristics of the plate primary filter mainly include the following aspects:
1.) Compared with ordinary glass fiber mesh or artificial fiber filter, the plate-type primary air filter has better filtering effect, larger dust capture and longer service life.
2.) The iron mesh of the plate primary filter can protect the filter material from being damaged, and effectively prevent the filter material from being deformed due to pressure.
3.) The filtration efficiency of the plate primary filter for particles ≥ 5.0 μm is between 40% and 60%.
(2) The use of the plate primary filter:
The plate type primary filter is usually used in the coarse filtration system of ordinary air conditioners, nylon mesh plate filter type, or can be used as a coarse filter screen for factory exhaust gas and processing dust collection. In addition, it is used in the electronics industry, pharmaceutical industry, semiconductor industry and other industries also have a wide range of applications.
Brief introduction of cardboard filter:
The filter material of the cardboard filter is packed into the high-strength cardboard in a folded form, and the windward area is increased. The dust particles in the inflowing air are effectively blocked between pleats and pleats by the filter material. Clean air flows out evenly from the other side, so the airflow through the filter is smooth and even. Nylon mesh pre air filter manufacturing company depending on the filter material, the particle size it blocks varies from 0.5μm to 5μm, and the filtration efficiency is also different.
The filter material of cardboard filter is non-woven fabric, fluffy glass fiber felt, plastic mesh or wire mesh. The most commonly used are non-woven fabrics and glass fibers. The efficiency can reach the initial effect or the middle effect.
Plate type mesh pre-filter
The plate-type mesh pre-filter is used in the pre-filtration of general air conditioning and ventilation systems to avoid dust accumulation in the system; pre-filtration of large air compressors; centralized ventilation and air-conditioning systems and return air filtration in clean rooms, extending the filter life of the latter stage. Service life; the ventilation system of general industrial workshops can meet the general cleanliness requirements of the air.
1.) High dust holding capacity
2.) Low resistance
3.) The plate filter adopts a lightweight plate structure, nylon mesh plate filter performance, polyester synthetic fiber, low initial resistance, good fire resistance
4.) Efficiency: G3, G4 (EN779)
Using plate aluminum alloy frame, with ABS plastic corners or aluminum alloy corners, the structure is stable.
The polyester fiber filter material covered with net makes the product have lower resistance and greater dust holding capacity.
1.) Pre-filtration of general air conditioning and ventilation systems to avoid dust pollution inside the system.
2.) Pre-filtration of large air compressors.
3.) Centralized ventilation and air conditioning system and return air filtration in the clean room to prolong the service life of the rear filter.
4.) Pre-filtration of the ventilation system of general industrial plants to meet the general cleaning requirements of the air.
