KRSA Single Stage Low-Pressure

KRSA Single Stage Low-Pressure - An Unrivalled Category Champion

KRSA Single Stage Low-Pressure compressors are purpose-built. Serving industries (such as Textile, Cement, Glass, Flue-Gas Desulfurization, and Pneumatic Conveying), they have set a high bar.

As compared to the conventional standard 7-bar compressors that waste energy when run at 2–5 bar, KRSA Low Pressure Compressors are made with a patented low compression ratio. This helps match your exact pressure needs...delivering optimal performance with very low energy loss.

KRSA Key Advantages Of Single-Stage Low-Pressure

Beautifully suited for low-pressure applications in diverse industries

Eliminating unnecessary compression, it helps offer the same FAD with 20–50% less power consumption.

Cost-Saving Operation: Dramatically lowers electricity bills while maintaining consistent output.

Sustainable Performance: Reduces your carbon footprint through energy-optimised engineering.

Double the Airflow & Faster ROI With KRSP Premium Single Stage Air Compressor


  • A regular screw compressor with a 132 kW motor at 7 bar gives you around 850 CFM.
  • Drop the pressure to 3 bar with a Kaishan Low Pressure model, and suddenly you’re getting around 1550 CFM.
  • Result? Same motor, nearly twice the air.
  • That boost means lower energy cost per unit of air and, in many cases, your compressor pays for itself in under a year.

KRSA Single-Stage Air Compressor Created for Low-Pressure Power

  • The KRSA Premium Single Stage Air Compressor is expertly engineered for industries where low-pressure performance is critical.
  • Its inspiring low compression ratio helps offer specific power, reducing energy consumption all the while maximising airflow.
  • The oversized separator tank also lowers oil carryover, providing cleaner air and longer equipment life.
  • Oversized separator tanks keep oil carryover to a minimum. This highly helps protect downstream equipment and improves product quality.
  • Every component is optimised for low-pressure operation, from the 5:6 screw profile to direct flow inlet valves.
  • Single-pass oil and aftercoolers make heat dissipation stable & consistent.
  • Comes with a 316 stainless steel control tubing, guarded components, and shrouded electrical hardware.
  • Direct drive transmission with premium energy-efficient motors. Also available with Permanent Magnet Motor technology!

Switch to KRSA Single Stage Low-Pressure.

  • In many plants, only about half the compressed air produced is actually used.
  • The rest is lost...almost 20% to artificial demand from over-pressurising, 20% to system losses like leaks and pressure drops, and 10% to poor practices (like using high-pressure air for simple tasks). That adds expensive energy bills and just wasted capacity.
  • The KRSA Single Stage Low-Pressure compressor helps fix this. Built for true low-pressure operation, it matches your plant needs at 2–5 bar and cuts needless compression.
  • Oversized separator tanks keep oil carryover to a minimum. This highly helps protect downstream equipment and improves product quality.
  • KRSA can deliver the same airflow with 20–50% less power, reduce artificial demand, and lower leakage losses.

Why Choose KRSA Single-Stage Low-Pressure Compressors

  • 5/6 lobe configuration with oversized rotors boosts air throughput, reduces specific power consumption, and enables slower operating speeds for enhanced durability.
  • The increased number of lobes minimises pressure differences between chambers, lowering leakage losses and improving efficiency.
  • Multiple rotor contact points reduce vibration and noise, while larger discharge ports lower air velocity and pressure losses. This results in better efficacy.
  • Amp up efficiency, extend equipment life & lower your costs, all with our KRSA Single Stage Low-Pressure Systems
  • Made with a low compression ratio to match your exact pressure needs. With this you get your desired outcome...optimal performance and minimal energy loss!
  • Perfectly suited for low-pressure applications in diverse industrial sectors.
  • Maximises efficiency by eliminating unnecessary compression, delivering the same FAD with 20–50% less power consumption.
  • Dramatically lowers electricity bills while maintaining consistent output.
  • Reduces your carbon footprint through energy-optimised engineering.
