Gas pressure boosters pump low pressure gas up to higher levels as required by downstream equipment. The discharge pressure is the sum of the incoming supply pressure and the pressure added by the booster.
In older areas, gas pressures may be lower than modern commercial and/or industrial sized equipment may require. In existing buildings, equipment additions from remodeling and upgrades may exceed existing pipe capacity. In new construction, there may be an advantage to reducing pipe header size for the upper floors of a building.
Gas pressure boosters are also useful where appliances require a variety of gas pressures. Using a booster to feed one or two higher-pressure appliances may be more economical than increasing the main regulator pressure and adding individual regulators at each low pressure appliance.
III Equipment Options
Gas boosters can be either hermetically sealed or shaft sealed. Shaft seal boosters are better suited for industrial applications, as their seal may require strict inspection and maintenance schedules to ensure safe operation.
High-pressure boosters enable the use of cutting torches. These boosters will generally provide gas in a range from 30 to 150 psi. Higher pressure boosters, up to 275 psi, allow customers to fill their own cylinders for portable applications.
