Air flow through the filter area of the actual known as the “effective filtration area.” In addition to a small number of inefficient filters, the effective filter area is often the windward side of the filter several times, several times, sometimes up to one hundred times.
Air flow through the filter area of the actual known as the “effective filtration area.” In addition to a small number of inefficient filters, the effective filter area is often the windward side of the filter several times, several times, sometimes up to one hundred times.
Most of the captured dust is concentrated on the windward side of the filter material. Effective filter in the filter area is large, can accommodate more dust, the filter on the long life.
Effective area, through the wind speed per unit area is low, the resistance of the filter is small.
Increasing the effective filtration area is the most significant means of extending the filter’s service life.
Experience shows that for the same structure, the same filter media, when the final resistance to determine: filter area increased by 50%, the filter life will be extended by 70% to 80%; doubled, the filter life Is about 3 times the original.
