Air Compressors Spare Parts

Air Compressors Spare Parts

Air Filters: essential for keeping dust and contaminants from entering the compressor, ensuring clean air output and protecting internal components.
Oil Filters: used in lubricated compressors to remove impurities from the oil, ensuring smooth operation.
Pressure Switches: regulate the pressure inside the compressor by controlling the start and stop of the motor.
Check Valves: prevent the backflow of air, ensuring the air flows in the correct direction during compression.
Gaskets: provide a seal between different parts of the compressor, preventing air or oil leaks.
Belts: transfer power from the motor to the compressor pump in belt-driven models.
Oil Separators: separate oil from the compressed air, especially important in rotary screw compressors.

Engine and Genset Parts

Engine and Genset Parts

Filters: filter the air entering the genset engine to prevent dust and particles from damaging internal components.
Oil Filters: keep the oil clean by filtering out impurities, ensuring proper lubrication of engine components.
Fuel Filters: filter out dirt from the fuel to prevent damage to the fuel system and maintain engine efficiency.
Regulators: regulate and stabilize the output voltage during genset operation. ity from the rotor to the stator.
Pistons: main moving components that travel up and down inside the cylinder, converting heat energy from combustion.
Piston Rings: seal the gap between the piston and cylinder wall to prevent gas leaks.
Spark Plugs: ignite the fuel-air mixture in gasoline engines.
Fuel Injectors: spray fuel into the combustion chamber in diesel engines.
Head Gaskets: seal the combustion chamber and prevent coolant or oil from leaking between the engine block and cylinder.
