Dunphy designs and manufactures gas boosters in the UK for industrial, commercial and energy applications, providing a robust, reliable and compliant solution where incoming gas pressure is insufficient for boilers, burners or process equipment.
Our gas booster systems are engineered to match your specific installation requirements, with options for natural gas, biogas and specialist applications.
If you are specifying or sourcing a gas booster, our engineering team can support product selection and installation. Contact Dunphy below to discuss your gas booster requirements.
A gas booster is a mechanical system designed to increase and stabilise gas pressure where the incoming supply is insufficient for combustion equipment or industrial processes. Gas boosters are commonly used with boilers, burners and CHP systems to maintain consistent gas flow and pressure.
A gas booster set is the complete system where incorporating one or more booster units alongside controls, regulators and safety components are ready for installation as a packaged solution.
Gas boosters use a centrifugal fan driven by an electric motor to mechanically compress incoming gas and deliver it at a controlled higher pressure. The system draws in gas at the incoming supply pressure and raises it to the level required by the connected equipment, maintaining a consistent and stable output regardless of fluctuations in the mains supply.
Controls and safety devices are integrated into each booster set to monitor performance, protect against pressure anomalies and ensure operation remains within safe limits at all times.
Natural gas boosters are used where mains supply pressure is insufficient for industrial boilers, burners or other gas‑fired equipment. Typical applications include combustion systems requiring stable pressure and reliable flow.
Standard systems can deliver pressure lifts of up to 82 mbar and volumes up to 1,300 m³/hr. Due to the properties of natural gas, system design is relatively straightforward, with components typically manufactured from mild steel.
Biogas boosters are designed to manage lower‑density and potentially corrosive gases. Biogas systems often require higher volume delivery to achieve equivalent energy output.
Our biogas boosters are engineered with appropriate material selection, including stainless steel construction and optional protective coatings, to ensure durability when handling gases containing hydrogen sulphide or siloxanes. Applications commonly include CHP, waste‑to‑energy and anaerobic digestion systems.
Dunphy gas boosters are installed across a wide range of sectors where consistent gas pressure is critical to safe and efficient operation:
Our gas boosters are designed and manufactured in accordance with relevant UK standards and guidance, including:
Manufacturing and testing are carried out under ISO 9001 quality management systems, with safety and compliance embedded throughout design and delivery.
High‑pressure gas booster pumps are used where gas must be delivered at pressures above standard combustion system requirements. These applications are typically industrial or process‑driven rather than building services‑led.
High‑pressure gas boosters are commonly specified for:
Selection is governed by pressure requirements, gas type, duty cycle, safety controls and compliance considerations.
As standard, Dunphy gas booster systems can be configured with one to three booster units delivering pressure lifts up to 82 mbar and volumes up to 1,300 m³/hr.
Where higher pressure or volume is required, bespoke engineered solutions are available.
Gas boosters are typically required when:
In these situations, gas boosters ensure consistent supply, improved efficiency and safe operation.
Gas booster installations are governed by IGEM/UP/2 guidance and BS 8487, which define safety, installation and maintenance requirements. Manufacturing and testing must also comply with ISO 9001 quality management standards.
Service intervals typically fall between six and twelve months, depending on application and manufacturer guidance.
Installation and maintenance must be carried out by suitably qualified engineers experienced in industrial gas systems and UK standards.
