Pre-Filters and Air Intake Filters
As the initial phase for your filtration system, pre-filters and air intake filters can set the stage for the quality of the entire paint filtration process. These filters are designed to filter the large airborne particulate which accumulate on fans and coils and prematurely clog final and ceiling diffusion filtration systems. Listed below are A.J.Dralle's entire line of pre-filters and air intake filters. For filters specific to your industry, click aerospace, industrial, or automotive.
