Description

What does a twin cylinder compressor do?

This twin cylinder compressor is a critical component of the pneumatic air brake system, ensuring consistent pressure delivery for heavy commercial vehicle braking performance. Built with high-strength components, it manages air compression through a precise 85.00 mm bore and 62 mm stroke to maintain stable system pressure.

Compatibility with Volvo FM12 engines

It is compatible with the vehicle's cooling system via water-cooled ports (M16x1.5) and features a 704cm³ swept volume for efficient air production. The assembly includes an integrated ESS feature and a water-cooled valve plate to manage thermal loads during continuous operation.

Installation and maintenance

For workshop technicians, correct installation is vital to ensure proper air flow through the M26x1.5 outlet and M35 air inlet port. Always verify that the drive gear and mounting flange align with the existing engine configuration before installation to prevent system mismatch.

System integration guidance

When replacing an old unit, ensure the water inlet and outlet connections are secure to prevent leaks in the cooling circuit. Consult your authorized distributor to ensure all mounting specifications are met.
