Believe that everyone has been bothered to the questions about the noise of pall filter for a long time, here attached the reasons for your reference as follows:

Pall filter has a certain use fixed number of years, and its efficiency will drop if beyond it’s life limitation. Besides, even lead to the loss of production seriously if there is something wrong with it ,especially on the filtration equipment. As we know that the hydraulic oil filter should be cleaned or replaced frequently if we want to guarantee the normal work of the engine . Otherwise the pall filter will produce noise once be blocked. while that noise is how to produce on earth? Filter will be blocked if Hydraulic oil are dirty and when the filter is in a state of congestion, it will make pressure of inside and outside large. Once the oil level have changed, it would be easy to make the air into the tubing and spread to squeeze in pump due to the different pressure, then it will produce aerodynamic noise.

The root cause of the problems have been found, then we can deal with them easily. Which  the simplest way is to replace a new pall filter. The filter should be keep maintenance work ,often to pall filter do some cleaning  if the economy does not allow  replacement regularly so that there was not many impurities in the filter.

However, general paper filter cannot be cleaned well, because paper filter belong to deep filtration materials. So there is no effect of cleaning.  Filter will be flatten if the filter is not  timely replaced once it reached life limitation, then cause the pollution of system.
