Primary Efficiency Pleated Sheet Air Filter
Product features
Primary Effect Sheet Filter is widely used in the field of air purification. Its structure is cleverly designed, consisting of several Primary Effect Sheet Filter material arranged in parallel, in the shape of a shutter, which gives it a large windward area and can effectively improve the air handling capacity.
The filter material is mostly non-woven or glass fibre, which is low-cost and easy to replace, and can efficiently intercept large particles of pollutants above 5 microns, such as dust, hair and pollen. In the ventilation and air-conditioning system, it is the first line of defence to prevent large particles from entering the air-conditioning unit, reducing wear and tear of the equipment, prolonging its service life and reducing energy consumption. In the electronic plant, it can pre-filter most of the dust, reduce the burden for the subsequent fine filtration, and guarantee the high cleanliness of the production environment of electronic products. In schools, shopping malls and other densely populated places, the sheet primary filter can continuously purify the fresh air, reduce pollutants and microorganisms, and create a healthy and comfortable space.
Product Characteristics
1.Inexpensive, light weight, good versatility, reduce operating costs.
2.The outer frame is made of aluminium or galvanised frame, and the filter material is made of high-quality polyester synthetic fibre with diamond-shaped mesh folding.
3.Compact structure, commonly used in the first stage filtration of ventilation system.
4.It is also suitable for air-conditioning and ventilation systems that only need one stage of filtration.

Applications
1.Pre-filtration of air-conditioning and ventilation systems to avoid the accumulation of dust and contamination inside the system.
2.Pre-filtration of large air compressors
3.Centralised ventilation and air-conditioning systems for clean rooms and return air filtration, to extend the service life of high-efficiency filters at the back stage.
4.Pre-filtration of general industrial plant ventilation systems to achieve general clean air requirements.
