Electric Screw Air Compressor

At the heart of this electric screw air compressor sits a mature screw airend chosen for precision rotors, heavy bearings and quiet, continuous duty. The screw airend comes from an established brand, with precisely machined rotors that keep vibration and air pulsation low over years of daily shifts. The load-bearing bearings are imported heavy-duty types rated for a service life above 80,000 hours, which is the figure that matters most to plants running multi-shift schedules, and the shaft seal uses a double-lip structure that keeps oil leakage close to zero around the drive end. An efficient air-oil separation element lowers oil carry-over at the outlet, and a microcomputer control system automates loading, unloading, fault protection and alarms so the station can run unattended. Because the unit is electric rather than diesel, there is no fuel tank, no exhaust stack and no engine service schedule, which keeps the machine room clean and lowers daily running cost at sites with stable grid power. The whole package is compact, which saves plant floor space, simplifies foundation work, and keeps routine service points within easy reach. The range spans 6.5 to 86 cubic meters per minute at 8 to 13 bar with 45 to 450 kW, matching general manufacturing plants as well as heavier process demands. The technical reason buyers choose this platform is reliability built into the rotating group: long bearing life, a sealed drive end and clean separated air are what separate a proper screw station from cheaper belt-driven alternatives, while the compact skid keeps the machine easy to place in existing workshops. For overseas buyers, the mature control logic and generic service points also mean local technicians can maintain the machine without specialized factory support.

Each unit goes through 100% inspection before it leaves the plant, including a 24-hour continuous run test, pressure stability test, sealing test, vibration test and noise test. We accept third-party inspection and supply a full test report and certificate with the machine. For a buyer, this means the unit arrives already proven on the test bench, not only checked visually.

Applications

 

General manufacturing and metal processing. The screw airend delivers continuous pulsation-free air that machining and assembly lines need, and the 80,000-hour bearing rating supports multi-shift operation.

Chemical, pharmaceutical and food plants. The efficient oil separation element keeps outlet air clean, and unattended control fits continuous process air supply.

Textile, electronics and power metallurgy sites. Compact footprint and stable pressure suit dense plant layouts where floor space and air quality both matter.

Customization

 

We configure voltage and frequency to your grid, choose the pressure and flow tier to your air load, and adjust the outlet connection, control panel language, canopy color and OEM branding. Structural customization is supported from your drawings or prototype.

All units are packed for export on wooden pallets with plastic foam cushioning to protect the canopy, cooler and control panel during sea freight. We support EXW, FOB, CIF and DDP terms. Payment is 30% advance before production and 70% balance before shipment. Standard units are delivered in 40 days, while customized units take about 60 days.
