Technical Advantages 


  • Class 0 Oil-Free Technology

        Our advanced labyrinth and screw seal assembly ensures a completely oil-free compression chamber,meeting                    Class 0 standards for true oil-free air.


  • Exceptional Energy Efficiency

    Designed with adiabatic compression,our oil-free screw blower achieves over 75%totalefficiency,offering 20-35% greater energy savings compared to traditional Roots blowers.It delivers higher discharge pressure with reduced pressure pulsation,ensuring stable  performance.


  • Low Noise Operation


        Engineered for low aerodynamic noise,our blower features a smooth output and optimized inlet and discharge                  design to minimize air flow fluctuations,offering a quieter alternative to traditional blowers.


  • Intelligent Control

    Equipped with an intelligent PLC control system that supports remote operation and multiple languages,it provides a user-friendly interface for greater convenience and operational efficiency.


  • Cost-Effective  Performance

    With an optimized structural design and stable operation,our blower requires no foundation,reducing installation costs and maximizing long-term value for customers.


Typical Applications 


1. Sewage treatment Industry 

  • Aeration: They are used in aeration basins to supply oxygen to aerobic bacteria, which break down organic pollutants in wastewater. Their high efficiency makes them the preferred choice over traditional Roots blowers for modern plants seeking to drastically reduce energy consumption.

  • Other Uses: Tank agitation, filter backwashing, and gas boosting (e.g., for biogas).


2. Food and Beverage Industry

  • Bottling & Canning: Used for purging bottles and cans immediately before filling to ensure they are clean and dry.

  • Fermentation & Mixing: Providing air for oxidation and fermentation processes (e.g., in yogurt production and beer brewing) without risk of oil carryover.


3. Pharmaceutical and Biotechnology Industry 

  • Fermentation/Bioreactors: Crucial for supplying sterile, oil-free air to large-scale bioreactors for growing cultures that produce antibiotics, vaccines, and enzymes.

  • Process Air: Used in fluid bed dryers, tablet coating, and other processes where air contacts product.

  • Material Handling: Conveying active pharmaceutical ingredients (APIs) and other powders.


4.Power & Energy Sector

  • Landfill Gas/Biogas Recovery: Extracting and compressing methane gas from landfills or anaerobic digesters for use in power generation or injection into gas grids.

  • Combustion Air Supplying: Providing air for combustion in waste-to-energy plants.
