Screw Compressors Supplier in Udaipur: Choosing the Right Model

If you run a factory, workshop or processing unit in Rajasthan, compressed air is probably one of the most important utilities you pay for. Choosing the right machine, and the right screw compressors supplier in Udaipur, affects your energy bill, your uptime and your maintenance costs for years. This guide explains how oil-injected screw compressors work and how to pick the right model for your plant.

How an oil-injected screw compressor works

Inside the machine, two meshing rotors squeeze air continuously as they turn. Oil is injected into the compression chamber to seal the small gaps between the rotors, absorb heat and lubricate the bearings. The oil is then separated from the air before the air leaves the package. Because the oil cools the compression process, an oil injected rotary screw compressor can run for long hours, which is why it is the standard choice for textile, cement, mining, engineering and general manufacturing plants.

Four things to check before you buy

  • Air demand and pressure: Size the compressor on your real consumption and the pressure your tools need, and leave some room for future growth.
  • Load pattern: If your air use rises and falls through the shift, a variable speed drive (VSD) model adjusts motor speed to match demand instead of running unloaded.
  • Drive type: Gear-driven machines suit continuous heavy-duty work. Belt-driven machines are a practical option for smaller workshops.
  • Air quality: Oil-injected machines leave a small trace of oil in the air, so pair them with the right dryer and filters. If your product cannot tolerate any oil, consider oil-free air compressors.

The Atlas Copco oil-lubricated range

N B Mercantile supplies the Atlas Copco oil-lubricated range. These are the main series:

  • Automan oil-lubricated piston compressor: for small or intermittent loads, with motor power from 1.5 kW to 8.1 kW.
  • G and Gx belt-driven screw compressors: for smaller workshops, from 2.2 kW to 22 kW, with working pressure from 7.4 to 13 bar(e).
  • GA gear-driven screw compressors: for continuous duty, from 15 kW to 90 kW, at 7 to 13 bar(e).
  • GA VSD+ variable speed series: for varying demand, from 7 kW to 250 kW, at 7.5 to 13 bar(e).

You can browse the full Atlas Copco range, including dryers, filters and nitrogen generators.

Why local support matters

A compressor is only as reliable as the service behind it. Oil, oil filter, air filter and separator element all need replacing at the intervals the manufacturer recommends, and a good supplier helps you plan this. N B Mercantile has served industrial customers since 1996 and has offices in Udaipur, Jaipur, Jodhpur, Bhilwara, Bhiwadi and Vadodara. The team helps with model selection, installation guidance and after-sales service for customers across Rajasthan and Gujarat, including Kota.

Frequently asked questions

Oil-injected or oil-free: which should I choose?

Oil-injected compressors suit most general industrial uses. Oil-free machines are preferred where the air touches food, medicines or other sensitive products.

When does a VSD compressor make sense?

When your air demand changes during the shift. A VSD slows the motor when less air is needed, which can reduce 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?

Capacity, working pressure, motor power, drive type and accessories such as dryers and filters. Installation and piping also add to the project cost.

What Is a Dry Rotary Vane Vacuum Pump and How Does It Work?

In many industrial setups, air removal plays a quiet but important role. When pressure drops inside a chamber, processes begin to behave differently. A Dry Rotary Vane Vacuum Pump handles this task without using oil inside the compression chamber, which changes how maintenance and performance are managed over time. In most cases, industries that deal with clean processes prefer such pumps because contamination risk stays low. NB Mercantile has been supplying these systems to various sectors where controlled vacuum conditions matter more than raw power. Internal Working Mechanism Inside the pump, a rotor sits slightly off-center. As it rotates, vanes slide in and out, creating pockets of space. These pockets trap air and move it along the chamber until it exits through the outlet. This movement may seem simple, but the absence of oil changes the internal dynamics. Friction and sealing depend more on precision engineering rather than lubrication. Over time, this design tends to reduce i...

Top Industrial Machinery Suppliers in India for Reliable & Advanced Solutions

Across manufacturing hubs and process plants, dependable machinery shapes daily operations. Production targets, safety standards, and maintenance schedules often depend on the efficiency of suppliers who understand industrial demands at ground level. When companies search for Industrial Machinery Suppliers in India , they usually look beyond product catalogues. They look for technical clarity, steady supply chains, and long-term service access. Changing Industrial Expectations in India Industrial development across sectors such as cement, textiles, mining, and food processing has increased the demand for specialised equipment. Many facilities now operate in tighter production cycles compared to earlier years. Downtime that once seemed manageable now directly affects cost planning and delivery commitments. In such situations, Industrial Machinery Suppliers in India are expected to provide more than equipment dispatch. They must assist with selection guidance, maintenance coordination, ...

Practical Guide For Efficient Industrial Compressed Air Systems Today

  Compressed air plays a major role in Indian factories, workshops, and processing plants. Machines, tools, and automation lines depend on a stable air source to maintain productivity. When air pressure drops or equipment fails, operations slow down and costs rise. Choosing the right compressor technology therefore becomes a business decision rather than a simple purchase, especially for growing industrial environments. Understanding The Working Method Of Screw Technology Among available options, the Oil Injected Screw Compressor has become a common choice because of its continuous duty design. Inside the system, two rotors mesh together and compress air smoothly without heavy pulsation. Oil is injected to cool, seal, and lubricate the chamber, reducing friction and heat. This results in consistent airflow, longer component life, and dependable performance. Many production facilities prefer an Oil Injected Screw Compressor when they need steady air for long hours. Unlike piston ma...
