Low Pressure Regulator Solutions
Equilibar specializes in the control of low and ultra low pressures.
We have several technologies which form the core of our low pressure offerings.
Our unique back pressure regulator technology offers precision control down to 0.02 psig.
Because these back pressure regulators are dome-loaded, we have also developed a
manual ultra low pressure regulator
to provide a stable set-point pressure.
For computer automation applications, we represent precision electro-pneumatic regulators (I/P and E/P transducers)
from Proportion-Air, with pressure ranges as low as 0-4 inWC.
Finally, because many applications require a pressure reducing regulator instead of a back pressure regulator,
we have developed low pressure systems
to provide unmatched stability and flow tolerance for demanding applications such as tubing extrusion.

Lowest range available!
Pressure reducing regulator controls in range of 0.25 to 7 inWC (0.02 - 0.25 psig).
For low flow or no flow air or inert gas applications only.
Highest available precision at high flow rates
Equilibar's new HFLPR is available with ranges as low as 0 to 0.5 psi and as high as 0-12 psi.
1/2" size allows for larger flow rates up to 24 SCFM. Intended for air and inert gases.
Equilibar is proud to represent pressure reducing gas regulators from Bellofram's Precision Controls Division.
These high precision devices provide economical solutions for applications down to 0.25 psig.
Equilibar is proud to offer the lowest pressure range available in electronic pressure regulators.
Proportion-Air's QPV Series offers full scale pressure ranges as low as 0.3 psi (10 inWC), with calibrated
ranges as low as 0-4 inWC. Custom configurations available for low flow / no flow applications.
Lowest range available!
Our Low Pressure Systems functions like both Pressure Reducing Regulator and a Back Pressure Regulator at the same time.
They provide dramatic sensitivity and precision with zero
hysteresis at pressures down to 0.5 inWC. Unlike any other commercial solutions, our system allows for bi-directional flow (supply and vent)
while maintaining tight precision.
Our unique back pressure regulator design provides the ultimate in sensitivity and precision. Operating
pressures are down to 0.25 inWC (0.02 psig). Sensitivity to 0.001 psig.
Use the LPR2 Ultra Low Pressure Regulator to provide set-point signal.
The Extech HD700 Digital Differential Manometer is perfect for working with low and ultra low pressures. Full range
is +/- 2 psig (54 inH2O, 13.8 kPa, 103 mmHg).
This reliable and feature-packed tool is economical, easy-to-use, and incredibly sensitive. Units display in bar, oz/in2, psi, inHg, mbar, mmhg, kPa, kg/cm2,
inH2O, ftH2O, and cmH2O. Resolution to 0.001 psi, 0.01 kPa, or 0.01 inH2O. Includes data acquisition software with serial
interface cable, battery, charger, and tubing.
