High efficiency air filter wind speed, rated air flow, resistance, efficiency must be in the test stand around the frame does not leak, the tightness must be strict, otherwise it will affect the accuracy of the test data and authenticity. The air resistance of the filter under the rated air flow is the initial resistance. […]

First of all in the production process at the same time, not according to the customer’s order requirements to do, is a deception, more serious is the impact of the entire ventilation system air volume, is also a direct cause of return. Medium efficiency PP material is required for large air flow, low resistance of […]

The dimensions of the air filter are allowed as follows: * End: longer than 500mm, the deviation is 0, -2mm; * Depth: Deviation of depth dimension is + 1.6mm, 0; * Diagonal: the diagonal difference between each end of the filter, when the diagonal is greater than 700mm, the tolerance is less than or equal […]

For the choice of media should note the following points: A, effective area, that is, the use of filter paper area, the capacity of dust on the large, small resistance. The use of life on the long, of course, also increased the cost of response; fiber diameter, the finer, cut blocking effect, a corresponding increase […]

A standard ventilation system to be tight, the connection of the sealing can be used soap bubble test, the same a standard test stand frame to maintain airtight, otherwise it will affect the filter resistance, rated air volume, wind speed, into the air filter The resistance of the air duct, the supply air volume of […]

The sodium flame method is to measure the efficiency of the high efficiency filter by detecting the number of sodium chloride droplets before and after the filter with a dust particle counter. Oil mist method is: the oil mist aerosol through the measured filter, using the turbidity method to measure the oil mist concentration before […]

The air / cargo shower room can remove the dust attached to the surface of people and articles, reduce the amount of dust brought into the clean air, and also play a function of both chamber to prevent dirty air from entering the door to ensure clean room with clean air conditioning system To achieve […]

As the glass fiber paper unique brittleness, so in the use and installation of the first to consider not touching sharp objects and repeated rubbing, followed by glass fiber paper in use should be as little as possible contact with water or other corrosive liquids, so as not to affect its normal use . Requirements […]

To increase indoor ventilation to improve cleanliness According to customer requirements (initial resistance, surface wind speed, rated air flow) and other related data to determine the filter width, height, depth, etc., can not change the size of the existing outlet, the number , Can increase the filter thickness, for example: 610 * 610 * 120 […]
