Oil-Free Air Compressor with Manual / Automatic Drain Valve
HSN Code: 84144090
The Chromgate Oil-Free Air Compressor is designed to provide a clean, reliable, and oil-free compressed-air supply for laboratory, analytical, pharmaceutical, research, medical, and compatible industrial applications where contamination from lubricating oil is undesirable.
The compressor is available in Diaphragm-Type and Piston-Type configurations to suit different airflow, pressure, and application requirements. As no lubricating oil is used in the compression chamber, the system helps minimize the risk of oil contamination in the delivered compressed air and connected analytical instruments.
The compressor is supplied complete with an air receiver tank, safety relief valve, pressure gauge, automatic pressure switch, manual / automatic condensate drain valve, non-return valve, air intake filter, delivery piping, outlet valve, and required standard fittings for safe and reliable operation.
Different motor capacities and receiver tank sizes are available to suit specific instrument requirements and operating conditions.

Selection & Customization:-
The appropriate compressor configuration can be selected according to the required airflow, working pressure, receiver capacity, motor rating, duty cycle, instrument air consumption, electrical supply, acceptable noise level, drain arrangement, and specific application requirements.
For analytical instruments such as AAS and Flame Photometers, the compressor should be selected according to the instrument manufacturer’s recommended compressed-air pressure and airflow requirements.
Note: Compressor type, motor capacity, airflow, receiver capacity, working pressure, dimensions, weight, noise level, electrical supply, outlet connection, and other technical parameters may vary according to the selected model and configuration.
