PortaGas Regulators

High-quality, economical solutions for your industrial hygiene, calibration gas delivery needs.

100 Series Regulator

The Portagas™ 100 series regulator is designed to maintain a constant flow rate to help ensure accurate monitor calibrations even as cylinder pressure drops. It features an N.I.S.T. traceable serial number, knurled knob for easy grip and passivated surfaces to help prevent reaction with calibration gases. The unique diaphragm design allows for a constant flow, even as cylinder volume/pressure are depleted. It features a stainless steel gauge and a wide choice of inlets and outlets.

Demand Flow Regulator

The Portagas pressure Demand Flow Regulators (DFR) are designed for use with our Portagreen™ line of cylinders. The DFR has been designed to provide the correct gas flow to instruments that have internal pumps. Typical activation suction is from 0” to 3” of water column. The DFR can be configured for inlet pressures ranging from 250 psig up to 3000 psig, with an outlet fitting of 3/16” hose barb. The DFR is available with an aluminum body for non-reactive gas services and a stainless steel body for reactive gas services.

Praxair Portagas Regulators

Preset, Fixed Flow Regulators

The Portagas preset, fixed-flow regulators are designed for use with our Portagreen line of cylinders. The flow is fixed to consistently provide the correct gas flow to instruments for calibration. Inlet pressure is configurable from 250 psig to 3000 psig. The gas outlet is a 3/16” hose barb with a configurable preset flow from .25 slpm to 6 slpm. An easy-to-read pressure gauge is included and the provided control valve allows for easy on/off capability.

Push-Button, Fixed Flow Regulators

The Portagas push button, fixed-flow regulators are designed for use with our Portagreen MegaBump™ cylinder. The flow is fixed to deliver consistent fixed flow with one push of the button. The gas outlet is a 3/16” hose barb with preset flow set at .5 LPM. These regulators are brass nickel-plated body for non-reactive and reactive gas service. An easy-to-read pressure gauge is included.
