Oil Injected Rotary Screw Compressor in India – Atlas Copco Range from N B Mercantile

An oil injected rotary screw compressor is the workhorse of most Indian factories. Two meshing rotors compress the air continuously, while oil injected into the compression chamber seals the gaps between the rotors, carries away heat and lubricates the bearings. The oil is then separated from the air before it leaves the package. Because of this, an oil flooded screw compressor runs cooler, delivers a steady flow and is built for long duty cycles in mining, cement, textile and general process plants.

As exclusive channel partner for Atlas Copco in Rajasthan, N B Mercantile supplies the full oil-lubricated range shown above – from the Automan piston compressor for small and intermittent loads to the GA, G and Gx screw series and the GA VSD+ variable speed models.

How to choose the right oil screw compressor

  • Air demand and pressure: size the machine on your actual consumption and the working pressure your tools and processes need, with some margin for future expansion.
  • Load profile: if your demand varies through the day, a variable speed (VSD) model adjusts motor speed to match it and avoids the energy lost in fixed-speed load/unload cycles.
  • Drive type: gear-driven GA units suit continuous heavy-duty work, while belt-driven G and Gx units are a practical choice for smaller workshops.
  • Air quality: an oil injected air compressor leaves a small trace of oil in the air, so add the right dryer and filters. If your product cannot tolerate any oil, look at our oil-free air compressors instead.

Oil Injected Screw Compressor FAQs

What is the difference between an oil injected and an oil-free screw compressor?

In an oil injected screw compressor, oil is fed into the compression chamber to seal, cool and lubricate, and is separated from the air afterwards, leaving a small residual trace. An oil-free compressor keeps oil out of the compression chamber entirely. Oil injected units suit most general industrial uses; oil-free units are preferred where air touches food, medicines or sensitive products.

When should I choose a VSD screw compressor over a fixed-speed model?

A VSD (variable speed drive) compressor such as the GA VSD+ series is worth considering when your air demand changes through the shift. It slows the motor down when less air is needed instead of running unloaded, which usually cuts energy use. If your plant draws a steady, near-full load all day, a fixed-speed machine can be a sensible choice.

What decides the price of an oil injected rotary screw compressor?

The main factors are capacity (air flow), working pressure, motor power, fixed or variable speed drive, gear or belt drive, and accessories such as an integrated dryer or filters. Installation and piping also add to the project cost. Share your requirement with N B Mercantile and we will suggest a suitable model and send a quote.

What routine maintenance does an oil flooded screw compressor need?

Regular checks of oil level, drain points and filter condition are needed, along with periodic replacement of compressor oil, oil filter, air intake filter and oil separator element as per the running hours in the manufacturer's schedule. Keeping the cooler clean and the room well ventilated also helps the compressor run efficiently and last longer.
