Related knowledge about vacuum pump filters

Vacuum pump filters refers specifically to the filter element in a vacuum pump and is a professional term in the filtration industry. Nowadays, vacuum pump filters are mainly used in oil filtration, air filtration, water filtration and other filtration industries. Vacuum pump filters prevent small particles and contaminants from entering the pump unit, or from getting exhausted into the atmosphere.When the fluid or gas enters the filter element with a certain specification of filter screen, its impurities are blocked, and the clean flow flows out through the filter element to achieve Clean filtering effect.

Advantage of vacuum pump filters

It has good compatibility and is suitable for filtering organic solvents such as strong acids and alkalis. It is not easily corroded, and its filtration area is very large, allowing deep filtration. This product can also effectively purify the air. It can filter out the smallest impurity particles to protect the engine. This also extends the service life of the machinery. At the same time, the sound volume of this device is also very low, which can effectively reduce the noise when inhaling air, and it also has good fuel-saving performance, which can save 10% of fuel, saving you a certain amount of expenses. At the same time, because of the special properties of its material selection, the vacuum pump exhaust filter has a stronger ability and its service life is also increased.

Vacuum pump filters maintenance knowledge

When refueling construction machinery, the refueling tool for the vacuum pump filters used by the construction machinery must be kept clean. Never remove the filter to speed up refueling. Workers should wear work clothes and clean gloves to prevent fiber impurities and solid impurities from falling into the oil.

Types of vacuum filters

1. Air intake filter: Effectively preventing the suction of solid particles and fine ash into the vacuum pump is achievable. Reduce mechanical wear and improve operational reliability. It can effectively protect system components while extending the service life of the pump.

2. Exhaust filter: Taking into account exhaust resistance, dust holding capacity and oil and gas separation performance, the three requirements must achieve the best balance.Differentiate separation purposes by utilizing diverse materials in both internal and external locations.

3. Oil filter: Mainstream filter used for lubricating oil filtration of imported vacuum pumps to extend the service life of the oil, installed in the oil circuit.

How to use and maintain imported vacuum pump filters

replace vacuum filter

1. Loosen the knob-type bolt to separate the filter housing from the head. Be careful not to lose the rubber seal and fiber gasket.

2. Carefully remove the spring and felt gasket, and then remove the paper core.

3. Use a brush to remove dust and foreign matter from the creases of the filter element, then lay it flat with your hands and pat it gently to make the remaining dust fall. Wipe off the dust on the inner wall of the housing and the dust on the fiber pad.

4.Reinstall the cleaned or new filter element in the reverse order of disassembly.

The importance of regular replacement of vacuum pump filters

Many users ignore the impact of working conditions on the life of the filter element. Application manufacturers under good working conditions may only replace the filter element after one year or even two years, but application manufacturers under poor working conditions will also ignore the replacement of filter elements. However, neglecting to replace the filter element for an extended period not only diminishes the oil fume filtration effectiveness but also hampers the vacuum pump’s performance.Failure to replace vacuum filter  for a long time will lead to increased fuel consumption, reduced filtering effect, and increased environmental burden.To ensure effective filtration, uphold vacuum pump performance, and minimize costs, it is advisable to regularly replace the vacuum filter based on the prevailing working conditions.
