Used air compressors for sale in Hyderabad

Why buy a used compressor from a yard rather than a listing?

A second-hand compressor bought from an online listing is a photograph and a promise. What you cannot see is the hour meter that was reset, the airend that whines under load, the separator that has been passing oil for a year, or the engine that starts well cold and loses power hot. You find those things out in your first month, at your cost.

A used compressor from a working yard is different in three ways. It has been run under load by people who service these machines every day. The parts that were replaced are listed, and the parts that were left alone are stated. And the same service engineers who prepared it are the ones who will attend it in your plant afterwards, so there is no gap between the seller and the service.

What is usually available

Stock changes week to week, because machines come in from fleet renewals, project closures and part exchanges. Rather than a list that is out of date the day it is published, this is the shape of what passes through the yard:

If you need a specific class – say a 400 cfm, 150 psig diesel unit, or a 50 hp electric screw – send it to us; machines in that class come up regularly and we will tell you when one is ready.

Used, serviced or refurbished: What you are actually buying

These words are used loosely elsewhere. Here they mean specific things.

• Used (as-is): a machine sold in the condition we received it, after a running inspection. You get the inspection report, you know what you are buying, and the price reflects it. No warranty.
• Serviced: a used machine on which the routine items – filters, oil, separator, belts – have been renewed and the machine run-tested.
• Refurbished: a machine that has been partly or wholly rebuilt: airend or engine attended where needed, coolers cleaned, valves and sensors replaced, control checked, then load-tested. These carry the six-month warranty.

The full definitions, what the inspection covers and what the warranty excludes are on the used and refurbished compressors page.

The six-month warranty, in plain words

Refurbished compressors are warranted for six months from the delivery or invoice date, and the warranty covers the whole compressor, not a short list of parts. It does not cover consumables (filters, oil, belts), damage from misuse or the wrong oil, work done by others during the warranty period, or accident and site damage. If the machine fails for a reason the warranty covers, our service engineers attend it; that is the point of buying from the people who service the machine.

How we match a used machine to your work

A used machine is a good buy only when it fits the duty. Before we quote, we ask four things: the pressure your tools or process need, the air they consume together, how many hours a day the machine will run, and where it will stand (dust, heat, ventilation, power supply). A workshop that runs a compressor twenty minutes in every hour can use an older piston machine happily; a plant that runs it twenty hours a day should be looking at a refurbished screw machine with an airend history, or a new one. We will say which, even when the answer is “buy new” or “hire for six months first”.

Seeing the machine

You are welcome to see and hear a machine run at the yard in Tarnaka before you buy, 7 days a week, 8:30 am to 8:30 pm. Bring the nameplate photo of the machine it is replacing, or the tool list, and a service engineer will go through the choice with you.

Part exchange and buying your old machine

We also buy used compressors and take machines in part exchange against a used, refurbished or new unit. Send the make, model, serial number, hour reading and a few photographs, and we will give you an indication before any inspection.

After the sale

Delivery and positioning can be arranged across Hyderabad and Secunderabad, the rest of Telangana and Andhra Pradesh, and by transport across India. Commissioning, the first service, an AMC and spares all come from the same team. The machine’s file – inspection, parts replaced, test readings – stays with us, so future service starts from a known history.

What the inspection actually covers

A used compressor is only as good as the questions asked of it before the sale. Every machine that comes into the yard goes through the same running inspection, and the report you receive follows the same order, so two machines can be compared line by line.

The report states which items passed, which were put right, and which were left as found. That last column is where an as-is machine differs from a refurbished one, and it is written down so there is no argument later.

What “refurbished” means mechanically

Refurbishment is not repainting. Depending on what the inspection found, a refurbished machine will have had some or all of the following: airend bearings and seals renewed or the airend exchanged; separator vessel opened, element and gaskets replaced and the scavenge line cleared; inlet and minimum-pressure valves rebuilt with kits; thermostatic element and oil cooler core cleaned or replaced; all filters, oil and belts renewed; sensors proved against a reference gauge; contactors and overloads checked and reset to the motor plate; on a diesel unit, injectors, filters, coolant, belts and hoses attended and the engine run to temperature under load. The machine is then run under load, the readings recorded, and the sheet goes into the file that follows the machine. Because the same technicians will service it afterwards, nobody has an incentive to hide anything.

Choosing between used, refurbished and new: The arithmetic

The right choice depends on three numbers: how many hours a day the machine runs, how much it costs when it stops, and how long you need it. A rough guide that holds for most buyers:

• Under about 4 hours a day, or intermittent use (garage, tyre shop, small fabrication): a used or serviced piston machine on a receiver is the economical choice; the duty is light enough that age matters little if the valves and rings are sound.
• One or two shifts, production depends on it: a refurbished screw compressor with a documented airend history and the six-month warranty, or a new machine if the price gap is small at the size you need.
• Three shifts, or air quality matters (food, pharma, paint, instruments): usually a new machine; the energy cost over the life of a 24-hour machine dwarfs the purchase price, and a newer, more efficient airend pays for itself.
• A project with a known end date: hire rather than buy; the hire or buy guide and the rental versus ownership calculator make the comparison.

Ask the service engineer to run the numbers for your case. He will show the purchase price, the expected service cost over two years, and the energy cost at your tariff, for each option side by side.

Buying a used compressor for Indian site conditions

Machines that have worked in Telangana and Andhra Pradesh carry the marks of it: cooler cores packed with dust, canopy foam eaten by heat, hoses hardened by summers at 45 °C on open sites. None of this condemns a machine, but it changes what to look for. A used portable unit for borewell work should have a recent cooler clean and a thermostatic valve that opens correctly, or it will trip on the first hot afternoon at depth. A used electric screw machine for a factory should be checked for the voltage it was running on; machines that have lived with a weak supply often have motor and contactor damage that only shows under full load. These are the checks our technicians make because they are the faults they get called to fix.

A worked example

A fabrication unit in the Jeedimetla industrial area runs plasma cutting, grinders and a small paint booth for about ten hours a day. Its demand works out at roughly 60 cfm at 7 bar with short peaks when the booth gun and the grinders run together. A new 15 hp screw compressor is one answer. A refurbished 15–20 hp screw machine with a renewed separator, serviced airend and the six-month warranty, paired with a cleaned receiver and a refrigerated dryer for the paint, is the other. The refurbished option costs less to buy, runs on the same power, and carries a known history; for a ten-hour day it is the sensible choice, and that is what we would recommend. For a 24-hour plant with the same demand the answer flips to new, because the energy saving of a modern airend over three shifts outweighs the purchase saving within a few years.

Questions to ask any seller of a used compressor

Whether you buy from us or elsewhere, ask these and expect written answers: What is the serial number and is the hour meter original? What was replaced, and what was inspected and left? Was the machine run under load, and what were the discharge temperature and the pressure rise time? What oil is in it now? What is the warranty, from which date, and what does it exclude? Who will service it after the sale, and how far away are they? A seller who cannot answer these is selling a photograph.

What happens after you decide

Once you choose a machine, we confirm the specification, the inspection report and the warranty terms in writing, arrange transport and positioning, and a service engineer commissions the machine on your site: electrical connection checked, pressure set, dryer and drains proved, operators shown the daily checks. The first service after installation is scheduled from that day, and the machine’s file – inspection, refurbishment sheet, test readings, commissioning notes – stays with us so that every later visit starts from a known history.

Frequently asked questions

Do you have small second-hand compressors, 1–5 hp, for a garage?

Yes, piston compressors on receivers in that range pass through regularly. Tell us the tools you run and we will say whether a used unit or a new one makes more sense at that size.

Can I buy a used compressor and have it delivered outside Hyderabad?

Yes. We supply across India by transport; service support is strongest across Telangana and Andhra Pradesh and within about 300 km of Hyderabad.

Is there a warranty on an as-is used machine?

No. As-is machines come with an inspection report and are priced accordingly. Refurbished machines carry the six-month warranty.

What if the used machine is not right for my work?

That is what the pre-sale questions are for. If the duty does not suit any used machine we have, we will say so and offer hire or a new machine instead.

Do you buy used compressors?

Yes, outright or in part exchange. Send the details and photos first.

Can I get a used compressor with a dryer and receiver as a set?

Yes. Many buyers replace the whole installation; we match a cleaned receiver and a serviced or new dryer to the machine so the air at the tool is dry.

Can I hire first and buy later?

Yes. Some buyers hire a machine of the class they are considering for a month to prove the duty, then buy a used, refurbished or new unit with the hire counted against it by agreement.

Will you take my old compressor in exchange?

Yes, in part exchange against any used, refurbished or new machine, after inspection.

What paperwork comes with a used machine?

The inspection report, the refurbishment sheet where applicable, the test readings, the invoice with the warranty terms, and the manual where we have it.
