LP4992 SP2 KNORR-BREMSE Twin Cylinder Air Compressor

This heavy-duty air compressor is a vital component within the pneumatic braking system, designed to ensure consistent air pressure for heavy commercial vehicle operations. The unit features a robust twin cylinder configuration with a water-cooling system to maintain optimal operating temperatures under demanding conditions.

The LP4992 SP2 is the OE equivalent of the KNORR-BREMSE LP4992 SP2 air compressor used in professional commercial vehicle systems. This high-strength component is engineered to meet strict technical requirements, featuring a cylinder bore of Ø88.00 and a 50 mm stroke to provide reliable performance. It is fully compatible with KNORR-BREMSE hardware and specialized technical specifications including an M26x1,5 air outlet and M16x1,5 water ports.

Maintenance of the air compressor system is crucial for workshop technicians to ensure long-term reliability. Technicians should monitor the water inlet and outlet connections (M16x1,5) and the air unloader port (M22x1,5) during routine inspections. Ensuring the integrity of the water-cooled valve plate and the through drive mechanism helps prevent system pressure drops and maintains efficient pneumatic delivery.

For precise installation, verify the compatibility of the M26x1,5 outlet and the Ø29 inlet port with your existing setup. This part is designed for high-load environments where durability and precision are essential for fleet safety.
