Atlanta Counter Differential Pressure Selection Guide
Air Regulators & Filter Regulators
Air pressure regulators are used to provide a constant outlet of pressure, separately from the inlet pressure or flow. They are most commonly used to reduce the pressure level required for downstream equipment, stabilizing the force applied to cylinders or minimizing pressure variation. Below are some of the Air Regulators that we keep in stock.
Compressed Air Dryers
A refrigerated compressed air dryer is a type of compressed air dryer, used to dry compressed air. Compressed air always contains water, coming from the air that is sucked in by the compressor. To protect your piping, tools and equipment, it's best to use a compressed air dryer to dry the air.
P/E Switches
A pneumatic switch is a device that activates or deactivates an electrical signal in a system based on the level of air pressure detected by the component. Below you will find the P/E switches that we keep in stock at the Atlanta warehouse.

Pneumatic Reversing Relays
A Pneumatic Reversing Relay is a modulating relay suitable for all types of heating and air conditioning control systems. It is used as a reversing relay to reverse and increase the capacity of the branch line pressure to the final control element.

Electric to Pneumatic 3-Way Valves
EP Three-way Valves are commonly-used to alternately apply pressure to and exhaust pressure from pneumatically-controlled devices, such as valves and damper actuators, by an electrical input energizing or de-energizing the solenoid of the valve.
