Air Compressors
When the compressor stops, every air tool, cylinder and pneumatic valve on site stops with it, which is why most plants treat compressed air as a utility rather than a machine. Air compressors convert electrical power into stored air at typically 7 to 13 bar, from receiver-mounted piston units serving a workshop bay to rotary screw sets feeding a factory ring main. Machinery Masters lists new and used compressors from verified sellers, with Atlas Copco, Ingersoll Rand, Kaeser, Hydrovane and CompAir machines regularly in stock alongside compact oil-free and low-noise units for point-of-use duties. You contact each seller directly, and qualifying listings carry financing.

Air Compressors Product Types
Compressors divide by how they make the air and how continuously they can make it. These are the main types in the live listings.
Rotary screw compressors
The standard for continuous industrial duty, running at full output all shift without resting. Listings such as Kaeser, CompAir and Atlas Copco sets span roughly 5 to 30 kW and beyond, with belt or direct drive and onboard controllers.
Rotary vane compressors
Compact, quiet machines suited to steady medium demand, with Hydrovane and Mattei units a regular presence. Slow rotational speeds give long service lives, and many are sold as combined compressor and dryer packages.
Piston and receiver-mounted compressors
Reciprocating compressors mounted on their own receiver, from Clarke and ABAC workshop machines upward. Best for intermittent demand such as garage bays and maintenance shops, where the receiver covers the bursts.
Oil-free and low-noise compressors
Machines that put no lubricant into the airstream, from quiet Jun-Air and Bambi cabinet units for staffed areas to Atlas Copco oil-free screw sets for processes that specify ISO 8573-1 Class 0 air.
Compressor and dryer packages
Combined sets that deliver dry air from a single footprint, pairing the compressor with an integrated refrigerant dryer and filtration. A practical route to clean air where plant room space is tight.

Porquê escolher a Machinery Masters
Apenas vendedores verificados
Cada vendedor é verificado antes de qualquer anúncio ser publicado. A Machinery Masters também revê a exatidão dos anúncios, para que os compradores possam investir com confiança em maquinaria de elevado valor.
Alcance global
Os anúncios provêm de vendedores de toda a Europa, da América do Norte e de outros locais. Esse alcance alarga as opções para além de qualquer rede regional de revendedores e é muitas vezes a única forma de encontrar modelos descontinuados em bom estado.
Opções de financiamento flexíveis
Os anúncios elegíveis dispõem de financiamento através de parceiros. As condições são apresentadas diretamente nas páginas de produto elegíveis, repartindo o custo em vez de esgotar o fundo de maneio de uma só vez.
Contacto direto com o vendedor
Não há nenhum intermediário entre o comprador e o vendedor. Pergunte pelo histórico de manutenção, combine inspeções e negocie diretamente com a pessoa que realmente conhece a máquina.
Applications and Uses
Compressor demand follows the shape of the work: continuous production wants screw machines, intermittent trades want receivers and pistons. Four settings dominate.
Factory ring mains
Screw compressors in the plant room feed distribution pipework serving actuation, tooling and blow-off across the site. Sites often run a duty machine with a used standby set to cover service windows and failures.
Vehicle workshops and garages
Receiver-mounted piston compressors power impact wrenches, tyre equipment and spray guns. Duty cycle is the number that matters, because a piston machine run continuously beyond its rating fails early.
Maintenance and fabrication shops
Vane and small screw compressors supply grinders, nibblers and plasma cutters at steady medium flow. A compressor and dryer package keeps moisture out of plasma torches and air tools.
Quiet duties near staffed areas
Low-noise cabinet compressors serve test benches, control rooms and instrument air points where a standard machine would be intrusive. Oil-free designs also remove lubricant carryover from sensitive processes.
Benefits from Machinery Masters
Compressors are bought both as planned plant and as urgent replacements, and a deep live market serves both situations.
01
Every compressor technology in one place
Screw, vane, piston and oil-free machines sit in a single category, so when more than one technology could do your duty you compare them directly rather than visiting a dealer per type.
02
Utility plant at second-life prices
An industrial compressor with a documented service history delivers the same bar and flow as it did new, and the saving against list price often funds the dryer and installation.
03
History confirmed before you commit
Hours run, airend overhauls and service records come straight from the verified seller through the listing, so condition is established before money or downtime is at stake.
Frequently Asked Questions sobre Air Compressors
Add the air consumption of each tool in cfm or litres per second, weight it by how much of the time each tool actually runs, and add around thirty percent margin for leaks and future kit. Compare that figure against the machine's free air delivery, not its displacement or motor power. Sellers can confirm the FAD rating on request.
Piston compressors suit intermittent workshop demand and cost least, but need rest time each hour. Screw compressors run at one hundred percent duty and suit production plants. Vane machines sit between the two, quiet and long-lived at steady medium flow. Map your demand pattern over a shift before choosing, not just the peak figure.
Only if the process specifies it. Spray finishing, instrumentation, electronics and breathing air duties typically call for ISO 8573-1 Class 0 or tight oil limits; general workshop and production air does not, because filtration downstream of a lubricated machine handles most requirements. Check your most demanding application's specification before paying the oil-free premium.
Read the hours meter and ask for service records, since the airend on a screw machine and the pump on a piston machine are the costly parts. Run the machine if possible, listen for bearing noise, and look for oil carryover at the outlet. Confirm the motor plate matches your supply before arranging transport.
Small piston and cabinet units commonly run on a 230 V single phase supply, while screw and vane machines above a few kilowatts need 400 V three phase, often with a dedicated breaker sized for the starting current. Ask the seller for the motor plate details so your electrician can prepare the supply before delivery.
