JE Nitrogen Regulator 50 Bar UK

Javac RS-750 Nitrogen Regulator 50 Bar is a professional OFN (Oxygen Free Nitrogen) pressure regulator — also known as a nitrogen pressure regulator, OFN regulator, or pressure testing regulator — designed for pressure testing and leak testing of HVAC, refrigeration, and air conditioning pipework systems in accordance with BS EN 378.

Key Specifications:

• Max inlet pressure: 300 bar
• Outlet pressure range: 0–50 bar (0–750 PSI)
• Outlet connection: 1/4" SAE flare
• Standard: BS EN 378
• Guarantee: 1 year
• Part number: RS-750
• Brand: Javac Edge

Compatible Systems:

• R32, R410A, R22, R134a, and all standard refrigerant HVAC systems
• Split AC, multi-split, VRF/VRV, and commercial refrigeration pipework
• Any copper ACR pipework requiring nitrogen pressure testing prior to commissioning

When to Use This Regulator:

• Required for F-Gas compliant pressure testing of refrigerant pipework before system commissioning — nitrogen pressure testing is mandatory under BS EN 378 and F-Gas regulations.
• Use to pressurise the system to the manufacturer's specified test pressure (typically 40–42 bar for R410A systems) and perform a leak decay test before evacuation.
• The 0–50 bar outlet range covers all standard HVAC pressure testing requirements including high-pressure R410A and R32 systems.
• The large pressure adjustment knob allows precise, easy pressure control on site without tools.

Frequently Bought With:

• Nitrogen Equipment & Accessories — regulators, adapters, and spare parts for nitrogen pressure testing
• Mastercool 99946-BT-2 Smart Manifold — for monitoring pressure during nitrogen testing and subsequent evacuation

Frequently Asked Questions:

Why do I need a nitrogen regulator for HVAC commissioning?

Nitrogen pressure testing is required under BS EN 378 and F-Gas regulations before evacuating and charging a refrigerant system. The regulator controls the outlet pressure from the nitrogen cylinder to the specified test pressure — typically 40–42 bar for R410A and R32 systems. Never use refrigerant gas for pressure testing.

What test pressure should I use for R32 systems?

R32 systems are typically pressure tested to 40 bar (high side) in accordance with the system manufacturer's commissioning instructions and BS EN 378. Always refer to the specific equipment manufacturer's guidelines. The RS-750's 0–50 bar outlet range covers all standard R32 and R410A test pressures.

What connection does the RS-750 use?

The outlet connection is 1/4" SAE flare, which is the industry standard for HVAC refrigerant hoses and manifold gauges. Connect directly to your manifold gauge set or nitrogen charging hose.

Is this regulator suitable for R410A systems?

Yes. The RS-750 is rated to 50 bar outlet pressure and 300 bar inlet, covering all R410A and R32 system pressure testing requirements in accordance with BS EN 378.

Can I use this regulator with any nitrogen cylinder?

The RS-750 is designed for standard UK OFN (Oxygen Free Nitrogen) cylinders. Check the cylinder valve thread compatibility before use — most UK trade nitrogen cylinders use a standard bull-nose or pin-index valve compatible with this regulator.
