Piston Air and Gas Compressors

Piston Air and Gas Compressors — Powerful Equipment for Manufacturing and Industry

Piston compressors remain one of the most popular types of compressor equipment in the world due to their reliability, efficiency and versatility of application. If you are looking for where to buy a piston compressor for production, workshop or industrial enterprise, our catalog offers a wide selection of piston air compressors and piston gas compressors from leading world manufacturers.

Industrial piston compressors are used in all industries — from small auto workshops to powerful oil refineries. Their main advantage is the ability to create high pressure with a relatively simple design and affordable maintenance cost.

Operating Principle of Piston Compressors

A piston compressor operates on the displacement principle: the piston, moving in the cylinder, compresses gas or air to the required pressure. This mechanism ensures efficient compression of the working medium and allows achieving pressures unavailable to other types of compressors.

Main Components of a Piston Compressor

• Cylinder-piston group — the main working unit where compression occurs
• Crankshaft — converts the rotary motion of the motor into the reciprocating motion of the piston
• Valve system — suction and discharge valves control gas flow
• Lubrication system — ensures longevity of moving parts
• Cooling system — removes heat generated during compression
• Receiver — accumulates compressed air and smooths pulsations

Types of Piston Compressors

By Number of Compression Stages

Single-Stage Piston Compressors

A single-stage compressor compresses air or gas in one piston stroke. Such units are optimal for pressures up to 8-10 bar and are characterized by simple design and low cost. Ideally suited for small productions, garages and workshops.

Two-Stage Piston Compressors

A two-stage compressor provides compression in two stages with intermediate cooling. This allows achieving pressure up to 40 bar with higher efficiency and less heating. Two-stage piston compressors are the standard for industrial applications.

Multi-Stage High Pressure Compressors

High pressure compressors with three or more compression stages create pressure up to 400 bar and higher. Used for filling cylinders, in the oil and gas industry and special technological processes.

By Lubrication Type

Oil-Lubricated Piston Compressors

Traditional oil-lubricated compressors use oil to lubricate the cylinder-piston group. They are characterized by high reliability, long service life and lower cost. Suitable for most industrial applications where a small oil content in compressed air is acceptable.

Oil-Free Piston Compressors

An oil-free piston compressor does not use oil in the compression chamber, which guarantees absolutely clean air at the outlet. Indispensable for food industry, pharmaceuticals, medicine and electronics, where air quality is critical.

By Type of Working Medium

Air Piston Compressors

Piston air compressors are the most common type, designed for compressing atmospheric air. Used to power pneumatic tools, automation systems, painting and other applications.

Gas Piston Compressors

Piston gas compressors are designed for compressing various gases: natural gas, nitrogen, hydrogen, oxygen, carbon dioxide and others. They have a special design taking into account the properties of the specific gas.

Advantages of Piston Compressors

High Efficiency Under Variable Load

Piston compressors maintain high efficiency even at partial load, making them ideal for productions with variable air consumption.

Ability to Create High Pressure

Unlike screw compressors, piston units are capable of providing pressure from 8 to 400+ bar, which is necessary for many technological processes.

Simple Design and Maintenance

The design of a piston compressor is well studied and refined over the years. Spare parts for piston compressors are available and inexpensive, and repairs can be performed on site.

Wide Range of Capacity

From small household models to powerful industrial units — piston compressors are produced in a wide range of capacity from 0.1 to 500+ m³/min.

Affordable Price

The piston compressor price is usually lower than a similar capacity screw compressor, making them attractive for small and medium businesses.

Application Areas of Piston Compressors

Industry and Manufacturing

Industrial piston compressors are used at machine-building plants, metalworking enterprises, in woodworking and other industries to power pneumatic tools and automated systems.

Oil and Gas Industry

Piston gas compressors are the main equipment for compression, transportation and processing of natural gas, associated petroleum gas and other hydrocarbons.

Chemical Industry

Special gas compressors are used for compressing various chemical gases in synthesis processes and production of chemical products.

Food Industry

Oil-free piston compressors provide clean air for packaging, bulk product transportation, aeration and other processes.

Medicine and Pharmaceuticals

For the production of medicines and medical equipment, oil-free compressors with air of the highest purity are used.

Auto Services and Service Stations

Piston air compressors are standard equipment for every auto workshop for powering pneumatic tools, tire fitting and painting.

Technical Specifications of Piston Compressors

When choosing a piston compressor, pay attention to key parameters:

• Capacity — volume of air or gas produced per unit of time (l/min, m³/h)
• Working pressure — maximum outlet pressure (bar, MPa, atm)
• Motor power — determines energy consumption and capacity (kW)
• Receiver volume — affects pressure stability and operating mode (l)
• Number of stages — determines maximum pressure and efficiency
• Drive type — electric, diesel, gasoline
• Design — stationary or mobile

How to Properly Choose a Piston Compressor

Determine the Need for Compressed Air

Calculate the total air consumption of all consumers taking into account the simultaneity factor and a reserve of 20-30% for development.

Determine the Required Pressure

Consider the requirements of the most demanding consumer and pressure losses in pipelines. For most pneumatic tools, 6-8 bar is sufficient.

Choose the Type of Compressor

For pressures up to 10 bar, a single-stage compressor is suitable, for higher pressures — a two-stage or multi-stage one. If air purity is required, choose an oil-free compressor.

Piston Compressor Maintenance

Regular maintenance ensures reliable operation and long service life of your piston compressor:

• Oil change — every 500-1000 operating hours
• Air filter replacement — every 1000-2000 hours
• Valve check — every 2000-4000 hours
• Piston ring replacement — when capacity decreases
• Bearing check — when extraneous noises appear
