BA-DSF-1, BA-DSF 2
Central air conditioning and ventilating systems. It can beused as a pre-filter in high efficiency system.
Filter media is a continuous glass fiber bonded together with athermo-setting resin. The "Graded Weave" produces a relatively open face with a progressive denser media towards theleaving face. The less dense portion at the front providesgreater dust holding capacity for the larger particles and thedenser portion at the back gives higher efficiency for the finerparticles. The frame is constructed using heavy gauge highwet-strength fiber board (chip board) Channel with metal support grid (Cap scrap)
