Air Liquide gas manifolds allow uninterrupted gas service to your application. Gas manifolds are designed to let you connect and changeout multiple cylinders of industrial gases in a safe and cost-effective manner. Plus, regulator handling is eliminated. A variety of models are available for almost any application.
Please note that gas manifolds are designed to distribute a single gas from two or more cylinders. Never mix gases in a manifold. Injury to personnel or damage to equipment may result.
High-Flow SwitchOver Manifolds
High-flow switchover manifolds handle flow rates of up to 3000 SCFH at delivery pressures up to 500 psig. They are ideal for providing continuous flow of gas between a primary and secondary supply.
The automatic changeover prevents downtime by automatically switching the gas supply from the primary cylinder bank to the reserve cylinder bank. All components including the delivery pressure regulator are enclosed and protected inside a tamper-resistant case.
Automatic ChangeOver for Cryogenics
This model prevents downtime by automatically switching from the primary cylinder bank to the reserve cylinder bank. All components including the delivery pressure regulator are enclosed and protected inside a tamper-resistant case.
Manifold headers are used to connect two or more cylinders for greater online storage capacity or higher flow rates. Model H single row wall-mounted manifolds are constructed of brass and are provided with station valves and mounting brackets as standard components.
Single Regulator Manifolds
Models SL, SR and D
Single regulator manifolds provide an economical means to regulate and control multiple cylinders with a single high-flow regulator (not included), without interruption of gas supply to the process. Several configurations are available.
Pressure Differential SwitchOver Manifolds
The Model S manifold uses two high-flow regulators connected to each bank that act as a changeover device. When the primary gas source is empty, this changeover automatically switches to the secondary supply, eliminating pressure fluctuations, outages and wasted gas.
