FAQ

What is the function of a compressor unloader kit?
The unloader kit manages the unloading phase of the air compressor, allowing it to stop pumping air once the required system pressure is reached, preventing over-pressurization.
Which systems is this kit compatible with?
This kit is designed to be compatible with Knorr-Bremse and Perkins systems used in heavy commercial vehicle applications.
How can I tell if my unloader kit needs replacement?
Symptoms of a faulty unloader include difficulty maintaining steady air pressure or a continuous running compressor that fails to unload properly.
What materials are used in these kits?
These kits are manufactured using high-strength components designed to endure the harsh operating conditions of heavy-duty pneumatic systems.
What are the OE reference numbers of this part?
2400 020 310 directly replaces Knorr-Bremse OE number LK4959S4. It also replaces Perkins OE number 2488A302S4.
