An oil-free compressor produces oil-free compressed air, which is achieved through dry volumetric or dynamic air compression without contact with oil.
Scope of application of oil-free compressors
Clean, oil-free compressed air (ISO 8573-1 class 0) is in demand by many companies operating in the medical, pharmaceutical, instrumentation, chemical and food industries. Many technological processes in these industries do not allow lubricants to enter the compressed air that comes into contact with the products being manufactured.
Oil-free reciprocating compressor
This type of equipment can be divided into 2 types: small, low-capacity reciprocating (diaphragm) compressors, which are mainly used in dentistry, for airbrushing and water aeration, and high-performance industrial oil-free units.
Oil-free reciprocating compressors DALGAKIRAN Pet Master are designed for the production of polymer products, they are capable of delivering from 3.6 to 23m3 of compressed air per minute at a pressure of up to 40 bar. The casing of this equipment is water-cooled, the moving parts of the mechanism are not cooled, so they are made with high precision from durable metal.
Oil-free screw compressor
Oil-free rotary screw compressors are the most common in the industry due to their wide range of capacities (3 – 50m3/min), high energy efficiency and relatively short payback periods. Due to their design features and efficient cooling system, this type of equipment can operate around the clock, producing clean compressed air with a pressure of 7-10 bar(n).
The principle of operation of an oil-free screw compressor, like its oil-filled counterparts, is to compress air using two coaxially rotating rotors (screws) that do not touch each other. The difference is the use of a “dry” compression chamber without lubrication of the rotors. This feature requires more precise machining of the compressor’s moving parts during its production. In addition, a standard oil-free screw unit is capable of compressing air up to 5 bar, which is why two-stage machines are most often used. These differences determine the higher cost of such equipment. Therefore, when selecting compressor equipment, you need to decide how critical it is to obtain compressed air with zero oil content. Or it will be enough to use less expensive oil-filled machines with a comprehensive compressed air treatment and purification system.
The DALGAKIRAN product catalog includes a series of oil-free screw compressors of the EAGLE series. They are energy-efficient, compact, have a wide range of capacities (3.4 – 50.1m3/min at 7.5/8/10 bar) and are equipped with frequency converters.
Oil-free scroll compressor
The principle of operation of the device is based on the interaction of two spirals – eccentrically moving and static, while the spirals do not touch each other. The process of air suction, compression and exhaust occurs due to the movement of air flow from the periphery of the spiral to its center, to the high pressure zone. This design offers a number of advantages:
a small number of moving parts and virtually no friction reduces vibration and thus noise during operation;
The spiral block has a compact size.
The disadvantages include the relatively high cost of the equipment – the scroll unit requires minimal tolerances in its production. It can be said that this is the most technologically advanced type among small capacity compressors.
DALGAKIRAN manufactures oil-free scroll compressors of the DS series with a capacity of 0.15 to 3.4m3/min and an operating pressure of 8 and 10 bar. DS series scroll compressors are widely used in the pharmaceutical, medical, electronics and food industries.
Centrifugal compressor (turbocharger)
This type of compressor refers to high-performance machines for dynamic compression of air and other gases. This is the most technologically advanced and complex type of compressor equipment. Turbocompressors are characterized by high performance (from 20 to 2200m3/min), a wide pressure range (2-16 bar(n) – standard models) and are used in industries that require a constant supply of large amounts of compressed air.
The main advantages of centrifugal compressors:
high performance and energy efficiency;
complete absence of vibrations;
production of oil-free compressed air;
compact size;
stable pressure, no pulsations;
high reliability and exceptional workmanship (at the 6 Sigma level);
minimal maintenance;
the possibility of continuous operation for a long time.
The purpose of oil-free compressors
The principle of operation of oil-free compressors, as the name implies, is the absence of lubrication in the compressor chambers. This ensures the production of compressed air of the highest purity, which is critical in many industries. The most common applications for oil-free compressors are in the food, pharmaceutical, electronics and medical industries. Dalgakiran is a manufacturer of this equipment, so we offer the highest quality oil-free compressors at very competitive prices.

Technical characteristics
The technical specifications of oil-free compressors can vary depending on the model and operating principle. The main parameters to pay attention to include:
Capacity. Measured in liters per minute (l/min) or cubic meters per hour (m³/h), it determines the amount of compressed air that the compressor can produce.
Pressure. The maximum operating pressure that the equipment can provide. Measured in bars or megapascals (MPa).
Power. It is measured in kilowatts (kW) and determines how much electricity the device consumes.
Noise level. It is measured in decibels (dB) and is an important parameter, especially for medical and laboratory environments.
