Blowers are the heart of a biogas facility, as they supply energy in the form of pressure to the biogas to transport/move it from its source, i.e., the production system (digester or landfill) to the various consumers (boilers, engine, turbine, flare, plant, and biomethane cleaning and production equipment). All of these consumers (machines, equipment, and technologies) require a certain amount of energy in the biogas in the form of pressure for proper operation.

Therefore, they are typical and important machines in these types of biogas facilities, where the biogas generally has low pressure. These machines, connected to the piping system, constitute the bloodstream of a biogas facility.

There are different types of blowers depending on their operating principle. The most commonly used blowers in biogas facilities are side channel, centrifugal, and rotary piston blowers (root).

Several parameters and factors must be taken into account when selecting a blower, such as biogas flow rate, required pressure, and type of biogas installation, among others. Proper selection of the blower will ensure proper operation of the biogas installation. And remember that this type of machine must comply with ATEX certification.
