The compressor continuously pumps air into the vehicle’s air reservoirs where it is stored and used for service brakes, parking brakes, and other air-powered components. When the compressor operates correctly, the braking system maintains stable air pressure and dependable response during vehicle operation.\u003c\/p\u003e \u003cp\u003eThe TF-400 design is known for its compact size and reliable airflow output. This particular configuration is commonly used on vehicles equipped with a \u003cstrong\u003ebelt-driven compressor system\u003c\/strong\u003e and a \u003cstrong\u003ewater-cooled housing\u003c\/strong\u003e. These compressors are often found on heavy trucks, vocational vehicles, and older fleet equipment where a small but dependable air supply compressor is required.\u003c\/p\u003e \u003ch3\u003eTF-400 Compressor Construction\u003c\/h3\u003e \u003cp\u003eThe TF-400 compressor operates using a \u003cstrong\u003etwo-cylinder reciprocating piston mechanism\u003c\/strong\u003e that compresses air during each piston stroke. The design uses a single-stage compression cycle which allows the compressor to deliver consistent airflow with relatively low horsepower demand from the engine.\u003c\/p\u003e \u003cp\u003eAt a typical operating speed of \u003cstrong\u003e1250 RPM\u003c\/strong\u003e, the compressor produces approximately \u003cstrong\u003e7.25 cubic feet of compressed air per minute\u003c\/strong\u003e. This airflow output allows the system to recharge air reservoirs following brake applications and maintain system pressure under normal driving conditions.\u003c\/p\u003e \u003cp\u003eThe compressor is driven by a pulley connected to the engine through a belt system. Internal moving components are lubricated through the engine’s oil supply while the compressor housing uses a \u003cstrong\u003ewater-cooled design\u003c\/strong\u003e to help regulate operating temperatures during continuous duty operation.\u003c\/p\u003e \u003cp\u003eTo maintain correct system pressure, the compressor works together with the vehicle’s governor and unloading mechanism. When air pressure reaches the upper limit of the system, the compressor unloads and temporarily stops compressing air. As pressure drops during braking, the compressor resumes pumping to restore the air supply.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul style=\"font-size: 14px; line-height: 1.7; margin-left: 18px;\"\u003e \u003cli\u003e\u003cstrong\u003eDirect replacement for Bendix TF-400 compressors\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003eCompact \u003cstrong\u003etwo-cylinder reciprocating piston compressor\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003eBelt-driven pulley configuration\u003c\/li\u003e \u003cli\u003eApproximately \u003cstrong\u003e7.25 CFM airflow output at 1250 RPM\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003eWater-cooled compressor housing\u003c\/li\u003e \u003cli\u003e4-hole base mount design\u003c\/li\u003e \u003cli\u003eLeft-side air inlet and outlet configuration (viewed from rear)\u003c\/li\u003e \u003cli\u003eDesigned for heavy truck and commercial vehicle air brake systems\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eIn stock and ready to ship from Ace Motor Parts\u003c\/strong\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e \u003ctable style=\"border-collapse: collapse; width: 100%; font-size: 14px;\" border=\"1\" cellpadding=\"10\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e227400X\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eCompressor Model\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eTF-400\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eDrive Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003ePulley Driven (Belt Drive)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMounting Style\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e4-Hole Base Mount\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eCylinders\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e2\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eBore\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e2.0625 in\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eStroke\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e1.5 in\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAir Output\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e7.25 CFM @ 1250 RPM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e3000 RPM (Water Cooled)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eHorsepower Requirement\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e1.2 HP @ 1250 RPM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eCooling\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eWater Cooled\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMinimum Unload Pressure\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e60 PSI\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaximum Inlet Temperature\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e250°F\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaximum Discharge Temperature\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e400°F\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAir Inlet Port\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eLeft (Viewed from Rear)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAir Outlet Port\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eLeft (Viewed from Rear)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eDischarge Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eFlange\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eOil Capacity\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e0.53 qt\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e31 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch3\u003eTypical Applications\u003c\/h3\u003e \u003cp\u003eThe \u003cstrong\u003e227400X TF-400 compressor\u003c\/strong\u003e is commonly installed in commercial vehicles equipped with belt-driven air compressors and water-cooled systems.
