Leak testing method for high efficiency filters

The Pao aerosol is sent to the upstream end of the hepa filter to be tested as a dust source. When the aerosol mixture is uniform, that is, the concentration value of the upstream is stable, the aeros

High efficiency filter maintenance skills

Maintenance of hepa filter is a very important problem, then how to maintain the hepa filter? First, let's take a look at hepa filters: hepa filters are mainly used to capture particles of dust and su

A method to capture a leak in the mid-effect filter specification

The way to capture a leak in the mid-effect filter specification is to first select a leaky air filter and then determine the location of the leak. Leak detection can be done by scanning with a laser

The effect of primary filter screen on the filtration of hepa filter in appli...

The primary filter is suitable for primary filtration of air conditioning system. It is mainly used to filter dust particles above 5 meters. The primary filter is made of imported polyester fiber filt

Moisture is the main cause of high efficiency filter bag clogging

Due to the advantages of high efficiency filter: small volume, simple operation, energy saving, high efficiency, bag filter widely used in various industries, but the use of the process will be blocke

Check that the intake and exhaust pipes are installed before using the hepa f...

Before using the hepa filter test, we first check whether the intake and exhaust pipes are installed. The inlet and outlet tubes are then fixed in grooves, making it difficult for the inlet and outlet

Principle of medium effect filter filtration

To intercept dust particles in the air and move with the flow of air in inertial motion or random Brownian motion or under the action of some field force. When particles move and bump into other objec

Application and characteristics of medium effect filter

Medium effect filter belongs to F series filter in air filter. F series medium effect air filters are divided into bag type and non-bag type, bag type includes F5, F6, F7, F8, F9, non-bag type include

Primary filters need to be replaced and cleaned

If the filter material used in the primary filter is air filter cotton, the primary filter is cleaned and replaced after a period of time so that the primary filter can always be used. Maintain good f

Cleaning instructions for primary filter

Primary filter is applicable to the primary filter of air conditioning system. It is mainly used to filter dust particles above 5 meters. There are three types of primary filter: plate type, folding t
