Oil-injected screw compressors are manufactured from AISI 4340 forged steel with 58-62 HRC surface hardness. Male and female rotors feature a 4+6 asymmetric profile machined to 0.001 mm accuracy. Capacity ranges from 18.5 to 355 kW, delivering 3 to 65 cubic meters per minute. Nominal working pressure is 7 to 15 bar with maximum output pressure of 20 bar. The oil injection system operates at 0.7 to 1.2 liters per second flow rate. Discharge air temperature stabilizes within 10°C above ambient. These compressors achieve 94% volumetric efficiency and 65% isothermal efficiency. An intelligent PID controller maintains specific energy consumption below 0.12 kW per cubic meter.
The rotary mechanism operates at a fixed 11:1 compression ratio and 2970 RPM speed. The two-stage cooling system includes oil-water and oil-air heat exchangers. A triple-layer oil separator with 99.97% efficiency reduces oil content to 3 ppm. An intelligent piston-type capacity regulator responds within 0.8 seconds. Sound pressure level at 1 meter ranges between 68 to 72 decibels. The complete package includes a soft starter drive and a 5-micron particle filter. Mechanically balanced design allows installation on basic foundations. The design service life is 80,000 hours with full component reparability.You can order and buy Oil-Inject Rotary Screw Compressors from Iran by contacting us through whatsaap and email.

Operating Principles and Maintenance of Screw Compressors
The working principle of a screw compressor is based on compressing air in the space between two helical rotors male and female. These rotors, by rotating simultaneously and intermeshing, reduce the air volume and increase pressure. Injected oil during the process provides lubrication, cooling, and sealing. For maintenance, daily checks of oil level, operating temperature, and system pressure are essential. The intake air filter should be replaced every 2000 hours to prevent particle ingress. The oil filter and oil separator must be replaced according to the manufacturers instructions typically every 4000 to 8000 hours. The cooling system radiator and fan should be cleaned of dust monthly. Leak tests and control valve servicing should be performed quarterly. Periodic oil analysis is recommended for early wear detection. Logging operating hours and services in a logbook is critical for preventive maintenance planning. Adhering to these points maximizes the devices efficiency and service life.
