SPEEDAIRE 39DK93 Air Regulator
This SPEEDAIRE compressed air regulator controls line pressure for pneumatic tools and equipment. It features a 1/4 inch NPT inlet and outlet with a maximum flow rate of 45 cfm. The zinc body handles up to 200 psi operating pressure and 175 degrees F. A top-mounted knob adjusts output up to 125 psi with an included pressure gauge and quick coupler.
Installers needing inline pressure control
Suited for main-line installation where regulated air is required at the point of use. The 4 inch width fits standard piping layouts. Builders needing higher flow capacity or larger port sizes should look at other models. This unit does not serve applications exceeding 200 psi inlet pressure or 125 psi regulated output.
45 cfm flow with 125 psi regulated headroom
Comfortably handles typical workshop air tools and actuators within its flow and pressure range. The 200 psi maximum inlet rating provides margin for compressor spikes. It runs out when demand exceeds 45 cfm or when downstream pressure must exceed 125 psi. The 175 degree F temperature limit covers most indoor compressed air systems.

Questions about this item
What size piping or fittings do I need to connect this regulator?
The regulator has 1/4 inch NPT air inlet and outlet ports, so matching NPT fittings and 1/4 inch pipe or hose connections are required for installation.
Can I keep my existing pressure gauge when installing this unit?
A pressure gauge is already included with this regulator, so a separate gauge is not necessary for operation.
How do I verify the regulator is controlling pressure correctly after installation?
Turn on the air supply, set the adjustment knob to the desired level up to 125 psi, and confirm the included gauge holds steady at that setting while air flows.
