Partition of the partition board, sealant, filter and other related parts of the role?

Corrugated aluminum paper separator can accurately maintain the distance between the folding layer, the smallest resistance, the maximum use of filter. In the corrosive environment, can be plated with ethylene partition. The edges of the baffles are folded to prevent damage to the media, and the thin baffles can have more folds, thereby increasing the […]

Air filter air velocity, rated air volume, initial resistance, efficiency, and other related parameters in the test process how to detect?

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. […]

In the assembly process misuse of the filter paper, that is, the effect filter (HV type) PP paper mistakenly used as a high-efficiency filter glass paper, this will cause serious consequences?

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 […]

In the production of filters at the same time, for the choice of media to pay attention to what the problem?

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 […]

What is oil mist and sodium flame method?

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 […]
