Dual-Cylinder Air Compressor for CAT C-15 3406E C-16 with Precise Mounting Holes and Built-in Pressure Relief Valve

For 175-6779 1756779 Air COMPRESSOR CAT C-15 3456 3406E C-16 Excavator engine parts

Specification

Description

Part number 175-6779 dual-cylinder air compressor, compatible with diesel engines of C-15, 3456, 3406E, C-16 engineering excavators, serving as the core air supply component for vehicle air brakes and pneumatic control systems. The product features split cast steel cylinder body matched with aluminum alloy valve cover, integrated pressure relief valve, standard threaded air inlet/outlet ports and precise flange mounting holes. Protective plugs are pre-installed for dust and moisture prevention. All pipeline holes and installation dimensions match target engines precisely, supporting direct replacement of old compressors to meet long-term pneumatic supply needs of heavy construction machinery.

Advantage

Precise Matching: Flange mounting holes, air ports and transmission connection dimensions fully follow matched specs for plug-and-play installation without modification.
Stable Dual-Cylinder Air Supply: Dual-piston design delivers fast air charging under heavy loads to guarantee steady air supply for braking system.
Heavy-duty Housing: High-strength cast iron main body resists vibration, oil corrosion, cracking and leakage under high-temperature and bumpy construction conditions.
Built-in Pressure Protection: Equipped with pressure relief valve to release excess pressure automatically, preventing pipe burst and component overload damage.
Superior Sealing: Wear-resistant piston rings and valve plates maintain great air tightness and reduce air leakage during long operation.
Complete Shipping Protection: All ports sealed with plastic plugs to block dust and moisture, avoiding jamming and rust during transportation and storage.

Performance

Efficient Air Output: Reciprocating dual-cylinder design builds working pressure rapidly at idle and high RPM to ensure reliable response of brakes and pneumatic devices.
Adjustable Pressure Control: Factory-calibrated relief valve keeps air pressure within safe range, balancing air supply efficiency and equipment safety.
High-temperature Resistance: Heat sink ribs on cylinder improve heat dissipation for continuous heavy-duty work, avoiding overheating and premature seal aging.
Anti-vibration Stability: Reinforced internal components prevent loose valve plates and air leakage under long-term bumpy operation of construction machines.
Wide Compatibility: Fits multiple excavator diesel engine models including C-15, 3456, 3406E and C-16, suitable for various heavy construction vehicles.
Low-power Consumption: Precisely machined piston and cylinder minimize friction resistance, without adding extra burden to engine operation.
