Product overview

Benefit from Adekom’s oil free screw blower design, now enhanced for biogas and RNG use.

Adapted from our core air-series technology, the KGF Series provides 100 % Class 0 certified, oil-free operation—ensuring contamination-free biomethane processing in treatment plants, CHP units, and gas injection systems.

At Adekom, we back our innovation with over 100 installations worldwide.

Our KGF blowers combine interior permanent magnet motor and VSD technology for continuous, flexible, and highly efficient operation. Ideal for low-pressure biogas applications, they deliver gas purity, reliability, and optimized energy performance at minimal cost.

Why Choose KGF for Biogas?

Product Features
State-of-the-art Oil-free Biogas Screw Blower Gas-end
  • Featuring a dry-type twin-screw oil-free gas-end, this unit ensures 100% oil-free compression—ideal for biogas and sensitive applications.
  • Advanced aerospace-grade coating reduces rotor clearance, enhancing efficiency and durability.
  • Proprietary rotor profile minimizes fluid dynamic losses, delivering up to 30% energy savings compared to traditional Roots blowers.
  • Direct-drive configuration eliminates belt-related maintenance and improves system reliability.
  • A precision-engineered gearbox optimizes rotor and motor speeds, enhancing stability and productivity.With a maximum pressure of up to 200kPa, it surpasses the 80kPa limit of conventional Roots blowers, enabling broader application coverage.


High-Efficiency Explosion-Proof VSD Motor
  • Rated IP55 for superior protection and enhanced environmental adaptability.
  • Certified explosion-proof by CSA and UL standards.
  • Equipped with premium-efficiency motors from globally recognized brands such as WEG or TECO, ensuring high energy savings and reliable performance.


High-Efficiency Inlet Filtration System
  • The stainless steel inlet separator tank integrates inertial separation and a 5-micron inlet filter element to effectively remove liquid water and  contaminants—greatly enhancing the reliability of the oil-free biogas gas-end.
  • Extended service life and longer maintenance intervals.
  • Automatic zero-loss condensate drainage system included.


Stainless Steel Discharge Silencer
  • Equipped with a stainless steel discharge silencer as standard, significantly reducing operating noise levels.
