Rochester's FP Series fine dust filter is recognized worldwide as the most proven and reliable high technology air filter on the market. Our mini-pleat V-Bank technology has proven to be cost effective and highly efficient in removing a wide variety of contaminants from the air stream in industrial, medical, office and original equipment applications. The FP's unique mini-pleat V-Bank design incorporates 193 square feet of high efficiency media within a 24"x24"x12" (nominal) rigid frame, significantly more than most other high efficiency filters on the market. The extended media surface creates a very low resistance to air flow. The low pressure drop results in lower energy costs and a longer filter life. The FP's rigid design allows it to withstand many unfavorable conditions especially variable air volume (VAV) systems. The FP's unique, inherently stable filter design distributes air evenly across the filter. It allows for large variations in air flow and pressure drop without affecting filter performance and efficiency. The FP performance is not affected by repeated fan shutdowns or changes in air flow velocities. Its rated at continuous air flow rates of 3000 cfm. The FP is designed to handle nearly all types of unusual circumstances: 100% relative humidity, turbulent air flow, intermittent exposure to water, repeated fan shutdown, desert and marine installations.
