Full or semi-automatic injection machine for producing round, square or rectangular air filters with polyurethane foam
Generally, less dense open cell foam is used for filtration because it has a less rigid structure that holds up more over time but closed-cell foams can be used for specific applications. The best air filter foams will meet the High-efficiency particulate air (HEPA) performance standards.Ordibehesht 20, 1400 AP
The foam pad that is attached to the air filter is called a pre-filter and it's there as an added layer of protection for the filters of vehicles that are driven in severe conditions.
OIL THE FILTER. Air filter oil prevents water, mud, dust and sand from going into the engine by maintaining impurities on the air filter. A well-greased filter ensures more power and longer engine life!
