About Air Preparation

Miniature Pressure Gauges

The small dial on these gauges allows for installation in tight spaces.

Fire-Sprinkler Pressure Gauges

Gauges are UL 393 listed for use with fire-protection service equipment.

Low-Pressure Differential Gauges with U-Tube

Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure.

High-Accuracy Pressure Transmitters

At least four times as accurate as standard pressure transmitters, these transmitters are ideal for use in laboratories and analytical testing applications.

Differential Pressure Transmitters for Liquids

Used with pumps, cooling systems, and other liquid applications, these transmitters remotely measure the difference in pressure between two inputs.

Tank-Mount Pressure-Regulating
Valves for Air and Inert Gas

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

High-Purity Tank-Mount
Pressure-Regulating Valves for Inert Gas

Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

Compressed Air Regulators

ARO Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air.

Parker Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air.

Wilkerson Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air.

Compressed Air Regulators

Adjust and maintain the pressure of your compressed air.

Tamper-Resistant Compressed Air Regulators

Prevent unauthorized adjustment and unintentional pressure changes with these regulators.
