Oil compressors

Oil-filled compressors are advanced pneumatic devices that use oil for lubricating, cooling, and sealing their moving components during the air compression process. By incorporating oil into the compression system, oil-filled compressors offer exceptional durability and the ability to achieve high working pressures, making them an ideal choice for professional and industrial applications that require a reliable source of compressed air.

Where Are Oil-Filled Compressors Used?

Automotive and mechanical workshops are a primary area of oil-filled compressor usage. These devices are perfect for powering impact wrenches, paint guns, pneumatic lifts, and cleaning systems. The stable air pressure provided by oil-filled compressors ensures efficient operation of all pneumatic tools.

In industrial and manufacturing facilities, oil-filled compressors are essential for powering assembly lines, packaging machines, industrial robots, and pneumatic control systems. Oil-injected screw compressors perform particularly well in heavy industries that require consistent high air pressure for many hours each day.

Construction and renovation companies use oil-filled compressors to drive pneumatic hammers, rotary drills, plastering guns, and other construction tools. The robustness of oil-filled compressors makes them ideal for harsh job site conditions.

Oil-filled compressors are also employed in car washes, paint shops, and tire service centres, supplying air for cleaning and drying systems, as well as specialized tools that require continuous access to compressed air.

Oil-filled compressors in welding power pneumatic tools used for joint preparation and post-weld processing (grinders, sandblasters, hammers), facilitate cleaning of slag and spatter, and support ventilation, fume extraction, and, if needed, welders’ breathing apparatuses. This improves weld quality and workplace safety.

Why Choose Oil-Filled Compressors?

Exceptional durability and lifespan are key advantages of oil-filled compressors. Oil effectively lubricates all moving parts, such as pistons, bearings, and rotors, significantly reducing friction and wear. As a result, oil-filled compressors have a much longer service life compared to oil-free units, providing better return on investment.

Higher efficiency and the ability to achieve greater pressures stem from the sealing properties of the oil, which prevent air leakage from the compression chamber. This allows oil-filled compressors to operate more effectively and reach technical parameters unavailable to oil-free alternatives.

Effective cooling provided by oil dissipates heat generated during compression, contributing to stable operation. This is particularly important for prolonged, intensive industrial use.

Cost-effectiveness – oil-filled compressors, especially piston models, are generally less expensive to purchase than comparable oil-free units, making them an attractive option for start-ups or businesses expanding their machinery.

How to Properly Service an Oil-Filled Compressor

Proper maintenance of oil-filled compressors requires regular oil and filter changes according to the manufacturer’s recommendations, typically every few hundred hours of operation. Daily draining of condensate from the tank and periodic checks of oil levels and the tightness of all connections are also necessary to ensure optimal performance and longevity.

Types of Oil-Filled Compressors Available

Piston oil-filled compressors are the most popular and versatile type. Air is compressed by the motion of a piston within a cylinder. Available in single-stage and two-stage versions, they offer different pressure ranges and are ideal for workshops and smaller industrial facilities.

Oil-injected screw compressors use two rotating screw rotors to compress air. Oil injected into the compression chamber provides lubrication, cooling, and sealing. These compressors offer continuous operation, high efficiency, and relatively low noise, making them preferred in industrial applications requiring a steady flow of compressed air.

Oil-filled vane compressors operate with a rotating rotor fitted with sliding vanes that move along the cylinder’s inner surface. Oil is critical for lubricating and sealing the vanes, ensuring efficient compression. These units are valued for durability, quiet operation, and the ability to perform under challenging conditions.

Oil-filled compressors are also available in various power configurations – single-phase 230V for smaller workshops and three-phase 400V for industrial applications requiring higher power and efficiency.
