The specialized engineers of BMC, using advanced software and technical experts, using the latest technologies, produce BMC air filters. An F1 filter must be very light, made from the best raw materials and improve performance. For this reason, only woven alloys with epoxy coating are used to protect against gasoline fumes and oxidation due to air humidity. The filtering material consists of a special cotton gauze soaked in low viscosity oil to provide the best possible air permeability. Advanced Technology BMC's technical staff has developed a specific production system based on soft rubber casting, which produces the familiar red BMC filters. They are made in a single piece without welded joints at the corners, thus avoiding the risk of breakage. This system, called "Full Molding," comes from R&D in F1 and is important for the technical and quality characteristics of BMC air filters.
