Vehicle and equipment filters cleanse air and fluid to improve performance and protect components from contaminants. Engine air filters prevent airborne contaminants from entering a vehicle's combustion chamber. Cabin air filters remove dust, pollen, and smog from a vehicle's heating and air conditioning system to prevent pollutants from entering the driver and passenger area. Crankcase ventilation (CCV) filters reduce diesel engine emissions (blow-by) from venting into the atmosphere. Vehicle coolant filters remove wear particles and corrosive deposits from coolant fluids to improve the performance of engine cooling systems. DEF filters remove contaminants from diesel exhaust fluid to improve the performance of Selective Catalytic Reduction (SCR) systems. Vehicle fuel filters prevent rust, sediment, and water from entering the fuel lines and clogging the pressurized components of a fuel injection system and reducing fuel's lubricity. Vehicle and equipment hydraulic filters cleanse fluid to improve the performance of moving components in high pressure hydraulic systems. Oil filters remove sediment, water, and other contaminants from oil to prevent wear on the engine's moving parts and ensure effective lubrication. Power steering filters cleanse sediment, water, and other contaminants from the fluid that lubricates and drives the hydraulic connection between the steering wheel and the front wheels of a vehicle. Transmission filters remove contaminants to prevent wear on moving parts and ensure effective lubrication in a transmission system.
