Industrial Screw Air Compressor Suitable for Workshop

After supplying over 800 industrial screw compressors to small and medium workshops across Europe and Southeast Asia, we know what matters: steady air pressure, low downtime, and energy savings you can measure.

Our 7.5kW direct‑drive screw air compressor is designed for workshops with 3-6 pneumatic workstations - auto repair shops, metal fabrication units, woodworking shops, or small assembly lines. In a real automotive workshop in Poland, replacing an old 11kW piston unit with this 7.5kW screw compressor cut electricity bills by 31% (verified by the owner's utility records) while delivering consistent 8 bar pressure even during peak hours.

Every unit is dynamically tested for 4 hours under full load before leaving our factory - we provide test reports with your serial number. That's the level of transparency we bring to every compressor.

From a technical standpoint, the direct‑driven configuration eliminates belt loss (typically 5‑8% efficiency drop) and reduces maintenance points. The motor and screw air end share the same shaft, resulting in mechanical efficiency above 96% at rated load.

Our air‑cooled system is specifically calibrated for workshop ambient temperatures from ‑5°C to +45°C. The 3600 rpm motor fan ensures adequate heat dissipation even during continuous 80% duty cycle operation. Combined with a large fin‑type oil cooler, the discharge air temperature stays within 15°C of ambient - critical for moisture control in downstream pneumatic tools.

The capacity range (0.3-1.15 m³/min) is achieved via an inverter‑ready design (or integrated variable frequency drive - please confirm model). This allows the compressor to match air supply to actual demand, reducing unloaded power consumption by up to 70% compared to fixed‑speed units. All performance data is measured according to ISO 1217 (Annex C) - the international standard for compressor performance testing.

Powers 3-4 lifts, impact wrenches, tire inflators, and a small spray gun. The 8 bar pressure is ideal for most European car lifts. With an optional refrigerated air dryer (dew point ≤3°C), you get clean, dry air for painting - no water spots.

Runs grinders, small shot blasting machines, and pneumatic clamps. The direct‑drive design delivers instant torque for short‑cycle operations. One of our clients in Vietnam uses this model to support 6 welding stations - pressure never drops below 7.5 bar.

Powers brad nailers, sanders, and dust collection valves. The oil‑injected screw design with a high‑efficiency separator keeps oil carryover ≤3 ppm - safe for finished wood surfaces.

Continuous 8‑hour shifts for pneumatic actuators, label applicators, and bag sealers. The integrated controller allows remote start/stop and fault alerts via a smartphone app (optional IoT module).

The range indicates a variable frequency drive (VFD) model. At 8 bar, the compressor can deliver from 0.3 m³/min (minimum stable speed) up to 1.15 m³/min (rated speed). If you need a fixed‑speed version (constant 1.15 m³/min on/off), we offer that as a lower‑cost option - just ask.

A simple rule: each pneumatic tool consumes roughly 0.2-0.4 m³/min under continuous use. For 3-4 tools used simultaneously, 1.15 m³/min is comfortable. For 5-6 tools, we recommend the 11kW model. Send us your tool list and duty cycle - we'll size it for free (no obligation).

Direct drive has no energy loss from belts (higher efficiency), lower noise, and no belt replacement. The only trade‑off is a slightly higher initial cost. For 8 bar applications, direct drive is the preferred choice for workshops that run daily.

Every 2000 operating hours (roughly every 6 months for a single‑shift workshop):
- Change air filter, oil filter, and oil separator.
- Top up screw air end oil (2.8L total). We supply a complete maintenance kit with every unit, including an illustrated manual. First‑year maintenance cost is <50.

The 120 kg weight listed is for the air end + motor + cooler only. We recommend pairing it with a 200L or 300L vertical receiver tank (ASME or CE certified). Tank is available as a package - let us know your space and local code requirements.

24 months on the complete unit, 36 months on the screw air end (parts only). Labor and remote technical support are included for the first 12 months. We keep a spare parts warehouse in Poland and Singapore for fast dispatch.

Yes - we offer custom voltage options: 220V/3Ph/60Hz, 415V/3Ph/50Hz, and 440V/3Ph/60Hz. Please specify your local supply when ordering.
