Rootech Services,Air Blowers based on Positive Displacement Rotary Air Blower principle, have been specially developed for pumping of biogas. These gas blowers are generally used in biogas lines to boost the gas pressures to meet the burner input demand.
These Air Blowers are generally vertical in construction, that is suction top and discharge bottom, so as to prevent any accumulation of corrosive matter inside the casing.
Since Air Blowers 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 applications.
Air Blowers, capable of handling different gases, are also available at Rootech Services. Material of construction and constructional details vary to meet different gas requirements.
For inflammable and toxic gases, leak tightness is ensured. Basic designs are modified, depending upon the nature of gas to be handled and customer's requirement. Water jet injection cooling can also be provided to keep the gas temperature low.
Provision for a vacuum switch is provided at the inlet of the Air Blowers, so that in case the biogas generation falls below the pumping speed of the blower, the blower trips and this prevents vacuum overloading. Similarly provision for a pressure switch is provided on the discharge line to safeguard the blower against excessive discharge pressures.
