Why vacuum pumps need to regularly replace filter elements

vacuum pump

The main reason why vacuum pumps need to regularly replace filter elements is to prevent performance degradation and contamination.


Over time, these impurities accumulate on the filter element, causing its efficiency to gradually decrease, which will cause a decrease in the pumping effect of the vacuum pump and also increase energy consumption. In addition, impurities on the filter element may also enter other parts of the vacuum pump, causing damage and contamination. Therefore, in order to maintain good operating conditions of the vacuum pump and reduce maintenance costs, it is necessary to periodically replace filter elements.

Here are some common industrial filter cartridge brands and their representative models:

  • Pall Corporation (Pall): GHP Series, HP Series, LP Series, RP Series, HC Series, AC Series, etc.
  • Hydac (Hydac): DH Series, SD Series, SH Series, ST Series, ZD Series, HB Series, SF Series, etc.
  • Donaldson (Donaldson): DC Series, DD Series, DF Series, DG Series, DL Series, DM Series, DP Series, etc.
  • Parker Hannifin (Parker Hannifin): E3 Series, D2 Series, D1 Series, C2 Series, B1 Series, A2 Series, etc.
  • Mahle (Mahle): KA Series, KJ Series, KK Series, KL Series, KM Series, KN Series, etc.

These are just some examples of common industrial filter cartridge brands and their representative models. Each brand has many other models available to choose from. The specific model chosen depends on the specific requirements and conditions of the application, such as working pressure, flow rate, medium type, filtration accuracy, etc.
