Ingersoll Rand Compressor R75

Replace No-loss condensate drain service module

Service Minimum pressure check valve (MPCV) service kit

The minimum pressure check valve (MPCV) shall be frequently tested and regularly maintained. Remove it from the compressor for testing. If operating conditions are particularly severe, the frequency of testing and maintenance shall be increased accordingly.

The user shall establish the frequency of such tests as it is influenced by such factors as the severity of the operating environment. For R30-37, the MPCV is installed as part of combination block.

The minimum pressure check valve (MPCV) should be tested and recalibrated in accordance with any national or local codes that may exist. If no code exists, Ingersoll Rand recommends that the valve is recalibrated at intervals of one year by a licensed contractor or qualified service personnel.

Sign off on the compressor maintenance

Ensure the compressor is electrically isolated for at least 15 minutes before commencing any maintenance work.

Remove the panels from the compressor.

Using a clean dry cloth, remove dust from the surface of the motor cowl and ensure all ventilation slots are free of obstructions.

Sign off on the motor cowl cleaning

Air compressor operating temperatures will be higher than normal if the external passages between the fins of the cooler cores become restricted with foreign material. Regular cleaning of the cooler surfaces will support the reliable operation of the air compressor system, improve the life of the compressor coolant and improve overall compressor efficiency.

When performed frequently as determined by site conditions and airborne contamination, more significant cleaning or replacement may not be necessary.

2. Isolate the compressor from the system.

3. Press the emergency stop to vent the separator tank and airend.

Fixed speed compressors can take more than two minutes to fully de-pressurize once stopped.

4. Ensure that the main power disconnect switch is locked off and tagged.

For any required lifting of air compressor parts or required tools, always use the proper certified lifting equipment, and employ sound working principles.

The flexible hoses that carry coolant through the cooling system may become brittle with age and will require replacement. Replace them as needed or every four years.

1. Depending on the location of the hose, it may contain compressor coolant. It is recommended to drain the coolant into a clean container. Cover the container to prevent contamination. If the coolant is contaminated, replace with new coolant.

3. Install the new hose and refill the compressor with coolant.

4. Start the compressor, check for leaks and check coolant level. Refill as necessary.

1. Check the retaining cap for dirt and debris and wipe clean.

2. Unclip the retaining cap and withdraw the old element.

3. Fit the new element and refit the retaining cap.

Replace - Coolant filter element

1. Remove drain plug from bottom of filter housing and drain coolant.

3. Remove the element from the housing.

4. Place the old element in a sealed bag and dispose of in a safe way.
