In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign and Materials\u003c\/strong\u003e\u003cbr\u003eQualified engineers using advanced software and expert technicians using the latest technologies produce BMC air filters. An F1 filter must be very light, must be made of the best raw materials and must improve performance. For this reason we use only alloy mesh with epoxy coating to ensure protection from petrol fumes and from oxidization due to the humidity of the air. The filtering material is composed of a special cotton gauze soaked with low-viscosity oil to give you the best air permeability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdvanced Technology\u003c\/strong\u003e\u003cbr\u003eBMC technical staff has developed a particular production system based on soft rubber moulding which produces the familiar BMC red filters. They are made in one single piece with no welded joints in the corners, thus avoiding breaking risks.
