Dual-stage Regulators: Squeeze Every Last PSI Out of Your Cylinder.
Stable Output at Low PSIs
The new Mountain High 109X series of Dual Stage (cascaded) high-stability regulators allows the useful pressure of a cylinder to be spent down to about 10 psi above the regulating pressure. This will still yield the specified flow rate for the application while maintaining specified pressure and flow requirements.
The dual-stage regulators are ideal for performance-critical applications where pressure stability, repeatability and low drop-out regulation of oxygen are important specifications as the supply runs down to nearly empty.
The graph on the right zooms in on the details of the output performance of the regulator while the inlet pressure had dropped to the regulation point (unity) ~ 20 psig of the final stage.
