The Chemetron® 550 Series outlet stations provide convenient access to medical gases in patient care locations. They are fully compatible with Puritan Bennett style geometrically keyed adapters.

The outlets are field-gangable in any order desired by the facility. Outlets are spaced 5″ (12.7 cm) center to center, and may be ganged with Chemetron modular electrical assemblies in a console arrangement. Outlet finish plates and rough-in plates are pin indexed using steel pins for positive cross-connection prevention. Primary valves are separate from the finish plate, allowing easy testing for leaks and cross connection. Primary valves are made of brass and contain a chrome-plated self-sealing poppet. Primary valves are field-adjustable to compensate for variations in plaster thickness of 1/2″ to 3/4″.

The type K copper inlet tube has a 1/2″ OD connection, and can rotate 360 degrees to accommodate any field piping arrangement. The primary gas check can be serviced without shutting off the gas supply.

The outlet stations are fully compliant with NFPA 99 and are cleaned for oxygen service in accordance with CGA G-4.1. The outlet is UL listed. Gas identification is provided by a poly-carbonate plastic insert, color coded by gas service.

The latch release is color-coded and labeled for the gas service. Release is easily accomplished with one hand using a push-button release. The primary valve poppet provides a dust-proof seal. Vacuum outlets may be used with or without slide brackets for vacuum collection bottles of up to 1/2-gallon capacity. (Where slide brackets are used, order one per vacuum outlet.)
