Recently, a customer ask us for help that his vacuum pump did not meet the standard vacuum degree after installing an intake assembly. However, after removing the intake assembly, the vacuum pump could reach the required vacuum degree again. In fact, this is not an individual case. I believe that many vacuum pump users also have encountered this situation. So, what is the reason for this?
Since the vacuum pump can operate normally after removing the intake filter, it indicates that the problem is with the filter. There are three possible reasons why the filter may affect the vacuum degree.
Firstly, poor sealing of the intake filter or of the connection. To verify it, just remove the filter element from the filter and run the vacuum pump. Then, if the vacuum degree still cannot meet the standard, it indicates that this is indeed caused by poor sealing. If the components at the connection are intact and tightly connected, it is caused by poor sealing performance of the filter.
Secondly, small size of the intake filter. that there was an error in the selection of the vacuum pump filter. The size of the filter should be selected according to the actual pumping speed of the vacuum pump. If the filter is small, the filtering area will also be small, which will naturally affect the pumping speed and vacuum degree.
Thirdly, high precision of the filter cartridge. High accuracy means high resistance, which would affect pumping speed. The precision of filter cartridges made of different materials varies. The precision also should be selected according to the actual pumping speed. And materials need to be selected according to working conditions, the precision of filter cartridges made of the same material also has different specifications to choose
