The Primary Efficiency Box Filter (RVFT-BF) is a durable and reliable air filtration solution designed for commercial and industrial HVAC systems. Constructed with a sturdy frame (cardboard, aluminum, or galvanized steel) and high-quality filter media such as non-woven fabric, polyester, or blended cotton, it ensures effective removal of dust and airborne particles. With an efficiency range of 30–35%, it is ideal for primary filtration in ventilation, air-conditioning systems, and cleanroom applications, operating efficiently under temperatures up to 70°C and humidity up to 90% RH.
Frame: Cardboard frame, Extruded aluminum frame, Galvanized steel frame
Filter media: Non-woven fabric (Polyester), Blended cotton
Face net: Spot-welded mesh, Expanded mesh
Efficiency: 30–35%
