CPM Series 3-7.5 HP

An oil-lubricated rotary screw air compressor requires regular checks of the compressor oil, air filter, oil filter and air-oil separator, along with inspection of drains, coolers and other service components. Compressor oil should be kept at the correct level and replaced according to the prescribed service interval. Chicago Pneumatic recommends following the model-specific maintenance schedule and using approved compressor lubricants and replacement parts to maintain efficiency, reliability and service life.

A 7.5 HP screw compressor is well suited to workshops and small businesses that require a steady supply of compressed air throughout the working day. Typical applications include tyre shops, automotive service centres, vehicle body shops, paint shops and dealerships, as well as pneumatic tools and other workshop equipment. The correct compressor size should ultimately be selected according to the combined airflow, operating pressure and duty requirements of the equipment being supplied.

Oil-lubricated rotary screw compressors provide smooth, continuous compressed air with low vibration and noise, making them well suited to sustained workshop and industrial use. The oil lubricates, cools and seals the rotary screw element, supporting efficient compression and long component life. Compared with many piston compressors, a rotary screw compressor can provide more stable air pressure, quieter operation and efficient performance during prolonged use. Appropriate filtration should be used where very clean compressed air is required.

The price of a 5 HP Chicago Pneumatic air compressor in India depends on its exact specification and installation requirements. Key factors include compressor capacity and working pressure, base-mounted or tank-mounted configuration, receiver size, whether an integrated dryer and filters are included, and any additional air-treatment equipment required. Installation, electrical work, piping, freight and service or maintenance packages can also affect the total project cost.

A CPM screw compressor is generally better suited to workshops with regular or sustained compressed-air demand. Rotary screw technology provides a steady, low-pulsation air supply and typically operates with less noise and vibration than a conventional piston compressor. Piston compressors remain practical for lower or intermittent air demand, but the CPM range is designed for businesses such as tyre shops, maintenance workshops, body shops and automotive dealerships where compressed air is used repeatedly throughout the day.

An air dryer is recommended when moisture in the compressed air could affect tools, equipment, paint finishes or the compressed-air network. Chicago Pneumatic offers the CPM as a compact complete solution with options including a receiver, dryer and filtration. A dryer lowers the dew point of the compressed air and helps reduce condensation downstream. The required air-treatment setup depends on the application and the level of compressed-air quality required.

Choose the compressor according to required airflow and working pressure rather than horsepower alone. Calculate the air consumption of equipment that may operate at the same time, determine the pressure required at the point of use, and allow reasonable capacity for pressure losses and future demand. A 3 HP unit may suit lighter requirements, while 5 HP and 7.5 HP models provide greater capacity for workshops operating more pneumatic equipment or experiencing longer periods of continuous demand. ATCORP can help size the CPM system for your application.

Yes. Rotary screw compressors are commonly used in automotive body and paint shops because they provide a stable, continuous air supply. However, spray-painting applications require properly treated compressed air. Moisture, particles and oil aerosols can affect paint quality, so the compressor should be paired with suitable drying and filtration equipment. Chicago Pneumatic offers dryers and coalescing filters that can be selected according to the required compressed-air quality.
