Protect-Air FluidReg® Inline regulator preset water/air

The FluidReg® (water) regulator is an independent membrane regulator that can be installed in every compressed air and fluid system. It supplies a constant, exact outlet pressure regardless of the input pressure. The pressure is factory-set and cannot be changed. This ensures that nobody can alter the specified pressure.

It is well known that the pressure of a water or fluid line normally is too high, fluctuates, and varies according to the height of the building. In that case the In-line FluidReg protects all equipment and components placed after it, because thus they will only receive the correct pressure. This is particularly important for all machinery/plants for or with dosing of liquids, for in this case expensive production stops can be avoided.

The standard FluidReg® is suitable for the media water, or compressed air. A modified version of the FluidReg® for medical application-such as oxygen, nitrous oxide N20 etc. is also available. Furthermore if the FluidReg is combined with a sprinkler nozzle, the best basis for cooling/cleaning by means of water spray or fog is created.
