Hubbell Furnas 69JG-Series Air Compressor Pressure Switch — 22A Heavy-Duty, Up to 175 PSI

The Furnas® by Hubbell® 69JG-series air compressor pressure switch automatically regulates tank pressure between two preset cut-in and cut-out values on electrically driven air compressors rated up to 175 PSI. The 69JG is the heavier-duty upgrade to the discontinued 69JF series, featuring 22-amp silver cad-oxide brazed contacts for superior performance and longer switch life. Its newly designed unloader valve mounts on the front or either side and rotates to any of eight positions, allowing quicker assembly with shorter tubing while preventing the compressor from starting under load.

Choosing Your Switch

Select the pressure range that matches your compressor's cut-in / cut-out (factory set):

• 80–100 PSI  ·  95–125 PSI  ·  115–150 PSI  ·  140–175 PSI

Then select the configuration for your setup:

• 1-Port / Unloader (Y): Single 1/4" NPT port with rotating unloader valve.
• 1-Port / Unloader + On-Off Lever (LY): Adds a manual auto-off disconnect lever for shutting the compressor off by hand.
• 4-Port / Unloader + On-Off Lever (LY2C): Four-port manifold (each 1/4" NPT) for easy mounting of relief valves and gauges, plus unloader and on-off lever.

Applications

Used to regulate tank pressure on small, electrically driven reciprocating air compressors up to 175 PSI — ideal for replacing worn or discontinued 69JF and 69MC switches on single- and three-phase compressors.

Backed by UL, CSA and CE approvals and built around Hubbell's rugged, field-adaptable Class 69J platform, the 69JG pressure switch delivers dependable automatic compressor control with the flexibility to build the switch around your compressor — not the other way around.
