The entire process of cleaning parts normally consists of three essential steps: washing, rinsing and drying. The purpose of the parts cleaning process, which is essentially a closed loop system, is to continuously regenerate and reuse the wash and rinse tank fluids.

Why do we need filtration in part cleaning operation?

The issue with maintaining a part cleaning system is that when the items being cleaned are transferred from tank to tank being sprayed or dipped, particles, oils, and surfactants are continuously being introduced into the wash and rinse solutions.

The chemistry of the parts cleaning solutions will change over time as a result of these pollutants and industrial waste, making it more difficult for the solutions to successfully clean the parts and hence meet cleanliness requirements.

These contaminants also have a big effect on the fluid treatment equipment, which is utilized to keep the hardness, pH, and other important water chemistry needs at the right levels.

Most parts washers utilize filtering technology to enhance the parts’ cleanliness and the process’ cost-effectiveness.

It’s essential to choose the right filtration technology if you want to cut down on scrap, rework, nozzle plugging and rejected components. Filtration will also shorten the overall lifespan of the wash and rinse fluids, lower labor costs, and cut disposal expenses.

What types of filters should be used?

Based on the different characteristics of the part cleaning system stage, we need to choose an appropriate filter for different phases.

The desired level of cleanliness (often determined by how or where the part will be used) determines the appropriate filtration method.

There are several stations in the cleaning procedure, each with its own fluid tank. A wash stage or stages are followed by a rinse stage or stages. Finer filtering is needed for each wash or rinses stage that follows.

  • Significant manufacturing waste must be removed from the wash water during the initial wash phases. In the same way, it is best to remove the debris along with the filter when removing it from the housing. As a result, there is less need to clean the filter housing while changing filters.
  • The primary rinse and secondary wash stations are made to increase the level of filtration. The best filters for this application are absolute-rated filters. The targeted particles will be removed from the wash and rinse water as a result.
  • It is crucial that the wash and rinse quality is not impacted by these restrictions, which could also be imposed by temperature and chemical compatibility.
  • Part cleanliness will be determined by the final rinse station, and a part can only be as clean as the rinse solution. The filter must therefore offer the highest quality while remaining reasonably priced.


Adding a filtration system to your parts cleaning system can significantly improve your productivity, prolong the fluid’s lifetime and reduce the labour and disposal costs.

Choosing the right filer for different wash phases is also important, according to the different characteristics of the cleaning process.
