Oil-injected / oil-lubricated rotary screw
Permanent magnet VSD and two-stage PM VSD screw air compressors for plant and process air, plus fixed-speed and application packages. Sized by pressure, free air delivery, and duty cycle—not by OEM brand pages.
Typical ranges
- Custom Build screw assembly focus: 7.5–75 kW (wider plant packages available on inquiry)
- Broader oil-lubricated screw lines commonly span ~7.5–132 kW; two-stage lines extend higher (e.g. tens to hundreds of kW) for large plant rooms
- Discharge pressure bands: plant air ~7–10 bar; low-pressure textile/process packages; medium/high-pressure variants on request
Typical configurations
- Fixed-speed screw with receiver for stable base load
- Permanent-magnet VSD screw for variable demand and energy saving
- Two-stage PM VSD screw when specific power and energy cost dominate
- Low-pressure screw packages for textile and process air
- Integrated / all-in-one packages (compressor with treatment skid) where floor space is limited

When should I choose PM VSD over fixed speed?
Permanent-magnet VSD suits variable demand and part-load plants where energy savings justify the drive. Fixed speed remains a strong fit for steady base load with a receiver and clear duty profile.
What does two-stage oil-injected screw offer?
Two-stage compression typically improves specific power versus a comparable single-stage machine at the same delivery pressure—useful when energy cost dominates lifecycle cost.
Can low-pressure packages serve textile or process air?
Yes. Low-pressure screw packages are commonly specified for textile and certain process duties where high discharge pressure is not required.
Do you publish OEM brand pages?
No. EntryAir works in category language and routes qualified inquiries. Brand introductions, if any, happen privately after fit is clear.
