What is the effective filtration area of filter?

For many filters, the filter material has a filtration effect. The total area of the filter media exposed to the flow of liquid or air, that is usable for filtration is an effective filtration area. A wider or larger filtration area has a larger surface for fluid filtration. The larger the effective filtration area, the more dust it can hold, longer service time. Increasing the effective filtration area is a significant means to extend the serving time of filters. According to the experience: for the filter in the same structure and filtration area, double the area and the filter will last about three times as long. If the effective area is larger, the initial resistance will be reduced and the energy consumption of the system will also be reduced. Of course, the possibility of increasing the effective filtration area is considered according to the specific structure and field conditions of the filter.

The wind speed also will affect the use of the filter. In any situation, the lower the wind speed, the better-using effectiveness of the filter. The diffusion of small particle size dust (Brownian motion) is obvious. With low wind speed, the airflow will stay in the filter material for a longer time, and the dust will have more chances to collide with obstacles, so the filtration efficiency will be high. According to the experience, for high efficient particulate air (HEPA) filter, If the wind speed is reduced by half, the dust transmittance will decrease by nearly an order of magnitude; if the wind speed is doubled, the transmittance will increase by an order of magnitude.

High wind speed means great resistance. If the service life of the filter is based on the final resistance and the wind speed is high, the service life of the filter is short. The filter can capture any form of particulate matter, including liquid droplets. The filter produces resistance to the airflow and has a flow equalizing effect. However, the filter cannot be used as a water baffle, a muffler, or a wind baffle at any time. In particular, for the inlet filter of gas turbines and large centrifugal air compressors, it may not be allowed to stop when replacing the filter elements. If there is no special muffler device, the working environment in the filter room will be very harsh.

If there is no special muffler device, the working environment in the filter room will be very harsh. For large mechanical silencers such as air compressors, you can choose a silencer. For example, the Hengko pneumatic silencer is easy to install and maintain. There are multiple models and multiple materials to choose from. It is mainly used to reduce the output pressure of compressed gas, thereby reducing gas discharge Noise. Not only air compressors but also fans, vacuum pumps, throttle valves, pneumatic motors, pneumatic equipment and other environments where noise reduction is required.
