Mixed Gas Primary Regulator – Bottle Mounted with Dual PRV

The Mixed Gas Primary Regulator is designed to provide controlled gas pressure from compatible mixed gas and nitrogen cylinders to draught beer dispensing systems.

Suitable for 30/70 mixed gas, 60/40 mixed gas and compatible beverage-grade nitrogen, this bottle-mounted regulator offers adjustable outlet pressure up to 45 PSI, making it suitable for pubs, bars, breweries, mobile bars and commercial draught installations.

Featuring a 3/8" push-fit gas outlet and two pressure relief valves (PRVs), it provides a practical solution for managing gas pressure in professional beer dispense systems.

Key Features

• Bottle-mounted primary regulator – Connects directly to compatible beverage gas cylinders.

• Mixed gas compatibility – Suitable for 30/70 and 60/40 gas mixtures.

• Nitrogen compatible – Can be used with suitable beverage-grade nitrogen cylinders.

• Adjustable outlet pressure – Maximum regulated output of 45 PSI.

• Dual pressure relief valves – Designed to relieve excessive outlet pressure at approximately 52 PSI.

• 3/8" push-fit outlet – Connects to compatible gas dispense tubing.

• Commercial construction – Suitable for regular use in professional draught beer installations.

Primary Gas Regulation for Draught Beer

A primary regulator reduces the high pressure within a beverage gas cylinder to a controlled working pressure suitable for the connected dispense system.

This bottle-mounted mixed gas regulator can supply gas directly to compatible keg couplers or feed secondary regulators where separate pressure settings are required.

It is suitable for installations dispensing lager, stout, ale and other kegged beverages, provided the correct gas mixture and operating pressure are used.

Compatible Mixed Gas and Nitrogen

The regulator is designed for use with compatible beverage gas supplies, including:

• 30/70 mixed gas: 30% carbon dioxide and 70% nitrogen, commonly used for nitrogenated beers and stouts.

• 60/40 mixed gas: 60% carbon dioxide and 40% nitrogen, used in certain draught beer and lager installations.

• Nitrogen (N2): Suitable for compatible beverage nitrogen applications.

Always follow the beverage manufacturer's recommendations when selecting gas mixtures and dispense pressures.

Adjustable Pressure up to 45 PSI

With a maximum regulated outlet pressure of 45 PSI, this primary regulator allows the gas supply to be adjusted to suit the requirements of the dispense installation.

The correct pressure depends on the beverage, gas mixture, keg specification, temperature and dispense system configuration.

Dual Pressure Relief Valves

Two integrated pressure relief valves provide additional protection against excessive pressure on the regulated side of the system.

The stated relief pressure is approximately 52 PSI.

These safety devices must not be obstructed, adjusted or modified.

3/8" Push-Fit Gas Connection

The regulator is supplied with a 3/8" push-fit outlet, allowing connection to compatible beverage gas tubing without requiring a separate threaded outlet adaptor.

The appearance and manufacturer of the push-fit fitting may vary.

Using a Primary Regulator with Secondary Regulators

For installations operating multiple kegs at different pressures, the primary regulator can supply compatible secondary regulators.

A typical arrangement is:

Gas Cylinder → Primary Regulator → Gas Line → Secondary Regulator → Keg Coupler

This configuration allows individual dispense lines to operate at their required pressures.

Technical Specifications

Installation and Compatibility

Before purchasing, confirm that the regulator's cylinder connection matches your gas bottle and that the regulator is suitable for the intended gas mixture.

Installation and pressure adjustment should be carried out by a competent person familiar with high-pressure beverage gas equipment.

Please note: The style of the supplied 3/8" push-fit outlet may vary.
