A Pre-Filter is a component in a filtration system that functions to filter large particles before the main filtration process is carried out.

​

This Pre-Filter is usually used in various applications, such as water purification system, air ventilation system, and other industrial devices, to reduce the load on the main filter and extend its service life. The Pre-Filter helps remoce coarse dirt such as sand, dust, leaves, and fibers so that the next filtration process can work more efficiently and effectively.
