Air Compressor Price in India: What Decides It and How to Compare Quotes
There is no single price for an air compressor. Six things decide the quote: motor size, screw or piston, working pressure, fixed speed or VFD, single- or two-stage, and what comes in the package. Over ten years the electricity usually costs far more than the machine, so compare quotes on air delivered per kW, not on price alone. Karan Micro Industries quotes every machine to the buyer's air demand, within 24 hours on business days.
What decides the price
Two quotes for a “20 HP compressor” can describe very different machines. These six things explain most of the difference.
| Factor | How it moves the price, and what to decide |
|---|---|
| Motor size (HP / kW) | A bigger motor costs more and gives more air, but how much air depends on pressure: the 20 HP KCS-20 gives 80 CFM at 8 bar and 50 CFM at 16 bar. Decide: Size on CFM at your working pressure, not on HP. The size calculator does it. |
| Screw or piston | A screw compressor usually costs more to buy for the same air, but it is built to run all day. Under about 4–5 loaded hours a day, a piston compressor is usually cheaper to own. Decide: Count your daily running hours (screw vs piston guide). |
| Working pressure | Higher pressure gives less air from the same motor and needs a different build: 16 bar for laser cutting, 30–70 bar for PET blowing. Each extra bar costs about 7% more energy (ELGi). Decide: Quote the pressure your machines need at the point of use, plus line losses, not the highest you can get. |
| Fixed speed or VFD | Every KCS model comes in both. The VFD version adds a variable frequency drive, so it costs more; it saves power when demand rises and falls, and little on a machine at full load all day. Decide: Look at how much your air demand changes through the shift. |
| Single- or two-stage screw | A two-stage screw costs more but compresses in two steps: the 75 HP KST-75 gives 446 CFM at 8 bar against 357 CFM for the single-stage KCS-75, about 25% more air from the same 55 kW motor. Decide: Price both on long running hours; Karan builds two-stage screws from 50 to 120 HP. |
| What the package includes | An air receiver, a refrigerated dryer, line filters, delivery, installation and commissioning all change the total. Decide: Ask for every item to be listed on the quote. |
The cost that is bigger than the price
In the US Department of Energy's example, a 75 HP compressor on two shifts spends about 76% of its ten-year cost on electricity, against 12% for the machine and 12% for maintenance. A 20 HP screw such as the KCS-20 draws about 16.3 kW at full load and uses about 130 units in an 8-hour shift. A machine that delivers the same air from fewer kW can earn back a higher price through the electricity bill. Put your own tariff and hours into the electricity cost calculator.
How to compare two quotations
- The same pressure. Compare air delivery at the working pressure you need; a figure quoted at a lower pressure looks bigger.
- Free air delivery, not displacement. FAD is the air you actually get; piston displacement is the cylinder's swept volume and is always higher. Karan's two-stage KC 742, for example, sweeps 17.32 CFM and delivers 13.83 CFM FAD (product table).
- kW per 100 CFM. Divide the power drawn by the CFM at your pressure; lower is better (Design World). The KCS-20 works out at about 20.4 kW per 100 CFM at 8 bar.
- What is included. Receiver size in litres, dryer, filters, delivery, installation, commissioning and GST. Karan invoices compressors under HSN code 8414 and shows the GST rate on the quote.
- Delivery, warranty and service. Karan usually delivers reciprocating compressors in 5–7 days and screw compressors in 10–14 days (sometimes longer). The warranty is usually 1 year, with the terms for each product in the quote, and Karan's own engineers install and service in Ahmedabad, Vadodara, Anand, Mehsana, Palanpur, Surat, Ankleshwar and Bharuch.
Typical packages Karan quotes
- Fabrication workshop, 2–3 hours a day: a two-stage piston compressor with its receiver, such as the KC 715T (15 HP, 51 CFM FAD).
- Textile or plastic unit, 16–24 hours a day: a KCS screw compressor with a refrigerated dryer, line filters and receiver, such as the KCS-25 (25 HP, 108 CFM at 8 bar).
- PET bottle line: a screw for 7 bar plant air, plus a KBC booster (to 35 bar) or a high-pressure compressor (to 70 bar) for blowing, with coalescing and activated-carbon line filters to reduce oil carryover.
- Fibre laser up to about 8 kW: a KCS-20 or KCS-30 at 16 bar with a dryer and fine filters (laser cutting guide).
What to send for an accurate quote
The air flow in CFM (or the list of machines it must run), the working pressure in bar, daily running hours, fixed-speed or VFD preference, and the city of installation. Karan replies with a recommended model and a quote within 24 hours on business days.

Ask our engineers01What is the price of an air compressor in India?
There is no single price: Karan Micro Industries quotes each machine because the price depends on motor size, working pressure, screw or piston, fixed speed or VFD, and whether the receiver, dryer, filters and installation are included. Send your CFM (or machine list), pressure, daily hours and city for a quote within 24 hours on business days.
02Why does a VFD screw compressor cost more?
A VFD model adds a variable frequency drive that changes the motor speed to follow air demand, so it costs more than the fixed-speed version. It earns that back where demand rises and falls through the shift; on a machine at full load all day it saves little. Every Karan Micro Industries KCS screw model comes in both versions.
03Is a screw compressor more expensive than a piston compressor?
Usually it costs more to buy for the same air, but it can cost less to own. Under about 4–5 loaded hours a day a piston compressor is usually the cheaper choice; beyond that a screw wins, because electricity is about 76% of a compressor's ten-year cost (US Department of Energy). Karan Micro Industries builds both.
04Does the price include the air receiver and dryer?
It depends on the quote, so check that every item is listed. Karan Micro Industries quotes the compressor alone or as a package with an air receiver fabricated in its own works, a refrigerated dryer and line filters, plus delivery and installation.
05How do I compare two compressor quotations?
Compare free air delivery (CFM) at the same working pressure, the kW per 100 CFM, and exactly what is included: receiver litres, dryer, filters, delivery, installation and GST. Each extra bar costs about 7% more energy (ELGi), so a machine set higher than you need costs more to run. Karan Micro Industries lists every item on its quote.
