LP 4974 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide consistent air pressure for critical pneumatic systems in heavy commercial vehicles. Designed with a focus on durability, the unit features a robust construction that ensures reliable operation under high-stress conditions. The integration of a water-cooled system and a specialized valve plate allows for efficient thermal management during continuous operation.

LP 4974 is the OE equivalent of the KNORR-BREMSE LP 4974 twin cylinder air compressor used in KNORR-BREMSE systems. This component is precision-engineered to meet exact technical specifications, ensuring seamless integration within the vehicle's pneumatic circuit. The design includes an M26x1,5 air outlet port and an M22x1,5 air unloader port to maintain stable pressure delivery.

For workshop technicians, this component offers ease of installation and high compatibility with existing heavy commercial vehicle architectures. The unit features a Ø88.00 cylinder bore and a 50 mm stroke to achieve a 608cm³ swept volume. Regular maintenance of the cooling lines and inspection of the M16x1,5 water ports are recommended to ensure long-term performance and prevent system overheating in the field.
