Direct Answer
Using an 8 bar or 10 bar compressor for an application that requires only 2.2 bar to 5.0 bar wastes energy through unnecessary over-compression. A low-pressure compressor is engineered specifically for this pressure band, delivering higher volume (FAD) per kilowatt. AirSpace Machinery configures the AirStream series for textile processing, pneumatic conveying, wastewater aeration and industrial blowing.
Why Match Pressure Instead of Over-Compressing?
- Eliminate over-compression waste — dropping working pressure from 8 bar to 3.5 bar can reduce specific energy consumption by up to 25–30%.
- Higher FAD output per kW — larger air ends optimized for high volume at lower pressure bands.
- PMV / VSD variable speed control — matches output to demand fluctuations.
- 55°C high-ambient rating — designed for demanding industrial environments.
Technical Planning Range — AirStream Low-Pressure Series
| Model Range | Power (HP / kW) | Working Pressure | Indicative FAD | Application Focus |
|---|---|---|---|---|
| AS-LP-30 | 30 HP / 22 kW | 2.2–5.0 bar | 4.5–6.0 m³/min | Textile / Pneumatic conveying |
| AS-LP-50 | 50 HP / 37 kW | 2.2–5.0 bar | 8.0–10.5 m³/min | Wastewater aeration / Conveying |
| AS-LP-75 | 75 HP / 55 kW | 2.2–5.0 bar | 12.0–15.5 m³/min | Textile air-jet looms / Industrial blow |
| AS-LP-100 | 100 HP / 75 kW | 2.2–5.0 bar | 17.0–21.0 m³/min | Large-scale pneumatic transport |
| AS-LP-150+ | 150+ HP / 110+ kW | 2.2–5.0 bar | 25.0+ m³/min | Heavy industrial process air |
FAD should be compared at the stated operating pressure under a consistent test method such as ISO 1217. Final dimensions, weight, voltage, frequency and configuration to be confirmed via RFQ.
Target Applications
- Textile air-jet weaving and yarn texturing

- Cement and chemical material handling
- High-volume industrial blow-off and washing
FAQ for Procurement Engineers
Why use a low-pressure compressor instead of throttling a standard 8 bar unit?
Throttling or regulating down an 8 bar compressor still requires the motor to compress air to 8 bar first, wasting significant electrical energy. A low-pressure compressor compresses air only to the required 2.2–5.0 bar band, saving substantial operating power.
What pressure range does the AirStream series cover?
The AirStream series is optimized for working pressures between 2.2 bar and 5.0 bar. For higher pressures, refer to our standard PMV or 16 bar laser series.
What is the delivery lead time?
Factory-direct delivery is typically planned within 7–35 days, depending on configuration, testing, documentation and production scheduling.
Where can I download technical specifications?
Technical manuals, spec sheets and energy reports are available in our Downloads Center.
⚡ Is Your Factory Bleeding Cash?
Most fixed-speed compressors waste $3,600/year in "Unload Tax." Test your waste level in 30 seconds.
