They generate compressed air that is stored in onboard reservoirs and used to activate service brakes, parking brakes, and other air-powered vehicle systems. Without a properly operating compressor, the vehicle cannot maintain the air pressure required for safe braking performance.\u003c\/p\u003e \u003cp\u003eThe TF-400 compressor series was designed for applications where a reliable air supply is needed but available mounting space may be limited. Its compact construction and efficient pumping design make it suitable for trucks and equipment that use a belt-driven compressor system.\u003c\/p\u003e \u003ch3\u003eTF-400 Compressor Design\u003c\/h3\u003e \u003cp\u003eThe TF-400 is engineered as a \u003cstrong\u003esingle-cylinder reciprocating compressor\u003c\/strong\u003e that operates through a single-stage compression cycle. As the piston moves through its stroke, air is drawn into the cylinder, compressed, and discharged into the vehicle’s air system.\u003c\/p\u003e \u003cp\u003eAt standard operating speeds, the compressor produces approximately \u003cstrong\u003e7.25 cubic feet of air per minute at 1250 RPM\u003c\/strong\u003e. This airflow capacity is sufficient to maintain the compressed air supply required by many medium-duty and commercial vehicle braking systems.\u003c\/p\u003e \u003cp\u003eThe compressor is driven by a pulley connected to the engine through a belt system. Engine oil lubricates internal components, helping reduce friction and maintain durability during continuous operation. The compressor housing is designed to dissipate heat through air cooling while maintaining stable performance under demanding operating conditions.\u003c\/p\u003e \u003cp\u003eThe air compressor works with the vehicle’s governor and unloading mechanism to maintain proper air pressure within the brake system reservoirs. When system pressure reaches the upper limit, the compressor unloads. Once pressure drops again during braking, the compressor resumes pumping to restore air pressure.\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\u003esingle-cylinder reciprocating compressor design\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003ePulley-driven compressor for belt drive installations\u003c\/li\u003e \u003cli\u003eApproximately \u003cstrong\u003e7.25 CFM airflow output at 1250 RPM\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003eAir cooled compressor housing\u003c\/li\u003e \u003cli\u003e4-hole base mount configuration\u003c\/li\u003e \u003cli\u003eLeft-side air inlet and outlet orientation (viewed from rear)\u003c\/li\u003e \u003cli\u003eDesigned for medium and heavy-duty commercial truck 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\u003e227406X\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\u003eCompressor Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eSingle Cylinder, Single Stage\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eDrive Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003ePulley Driven\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\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\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\u003eMaximum Speed\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e3000 RPM (Water Cooled) \/ 2400 RPM (Air 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\u003eAir 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\u003e29 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch3\u003eTypical Applications\u003c\/h3\u003e \u003cp\u003eThe \u003cstrong\u003e227406X TF-400 compressor\u003c\/strong\u003e is commonly used in medium-duty and heavy-duty commercial vehicles equipped with belt-driven air brake compressors.
