The unique Equilibar Ultra Low Pressure Regulator controls down to 0.3 in H2<\/sub>0 \/ 1 mbar(g). Designed for static and very low flow applications, the patent pending LPR2 design extends the control range well below other commercially available regulators.<\/p>

The LPR2 is available in a “no-bleed” model (very low bleed) or with a bleed orifice, which provides for more stability and responsiveness when lowering the setpoint pressure. The standard (very low bleed) option is recommended for most bottled gas applications to minimize consumption.<\/p>
