EVEREST Blowers Compressors based on Positive Displacement Rotary Air Blower principle, have been specially developed for pumping of Biogas. These are generally used in biogas lines to boost the gas pressure to meet the burner input demand. These are generally vertical flow type in construction, i.e. suction top & discharge at bottom, so as to prevent any accumulation of corrosive matter inside the casing. Since they operate in closed loop, suction and discharge silencers are generally not required. Special material of construction, lubrication and sealing arrangements make them ideal choice for Biogas boosting applications.
