Compressed Air and Gas Pressure Reducers

Precise pressure control for pneumatic systems, nitrogen, inert gases. FRL filter-regulator-lubricator units for complete air preparation.

Pressure control in pneumatic systems

Compressors deliver air at high pressure (8–12 bar), but most pneumatic equipment — cylinders, valves, tools — operates optimally at 5–6 bar. A pressure reducer at each point of use delivers exactly the pressure required.

Reducing pressure where it's not needed saves energy: every bar reduction represents approximately 7% savings on compressor costs. Equipment also lasts longer when fed at the correct pressure.

Roffia distributes compressed air regulators from Danfoss and FIP for industrial and commercial applications.

Why is a pressure reducer needed on compressed air lines?
Compressors typically operate at 8–10 bar, but most pneumatic tools and actuators work optimally at 5–6 bar. A pressure reducer at each work station delivers the correct pressure, extending equipment life, improving control, and saving energy — each bar reduction saves approximately 7% on compressor running costs.
What is the difference between air regulators and gas regulators?
Functionally similar, but gas regulators have dedicated connections (different for each gas per CEN/ISO standards), compatible materials, and calibrated flow capacities. Industrial compressed air uses standard BSP/NPT threads and NBR/EPDM seals. For specific gases (nitrogen, CO₂, argon) or high-purity applications, contact us for certified models.
With or without pressure gauge?
Regulators with integrated gauge (or gauge port) allow immediate visual monitoring of the outlet pressure — recommended where consistent pressure is critical. Models with two gauges show both inlet and outlet, useful for diagnosing supply issues. For panel-mounted applications, separate gauges may be preferred.
How do I size a compressed air pressure reducer?
Key parameters: flow rate (Nl/min or m³/h), maximum inlet pressure, required outlet pressure range, and connections (G 1/4, G 1/2, G 1...). Size the reducer at least 20% above actual flow to avoid excessive pressure drop. Contact us for sizing support.
What is an FRL unit?
FRL (Filter-Regulator-Lubricator) is a combined unit integrating air treatment in one compact block: filter removes particles and water, regulator sets pressure, lubricator adds oil mist for pneumatic tools. Standard on industrial pneumatic lines to condition air before tools and actuators. Available in sizes 1/8" to 1".
Which brands of compressed air regulators do you supply?
Roffia distributes pneumatic regulators from leading manufacturers: Danfoss for industrial applications, FIP for air treatment systems, plus components from various suppliers for specific requirements. Stock availability for fast delivery.
