SDDF 30 filters consists of a filter head with a screw-in filter bowl. Standard filter is without bypass valve. 

The function of the hydraulic filter is to filter out various impurities in the hydraulic system. The main sources are mechanical impurities that remain in the hydraulic system after cleaning, such as rust, welding slag, iron filings, paint and cotton yarn, etc., external impurities entering the hydraulic system, such as through the oil filler entrance and dust entering at the scraper seal, metal powder generated by relative wear and movement, colloid, asphaltene, carbon residue, etc. due to oxidative deterioration of the oil.
