Schneider Electric 9013FHG2J27X Pressure Switch

Schneider Electric's 9013FHG2J27X Pumptrol pressure switch delivers automatic control for small air compressors and pumps with an 80–100 psi operating window and a built‑in unloader valve. This single‑port electromechanical switch uses a fixed differential to cycle the motor, typically turning the compressor off at about 100 psi after reaching the 80 psi set point, while venting residual pressure through the two‑way release port to ease restart. The unit plugs in via a 1/4" NPSF connection and is part of the 9013 Class FHG Pumptrol family, a common choice for compact compression or pump control. Designed for straightforward installation and reliable operation in tight spaces, it provides the essential combination of precise pressure switching and unloader functionality in a compact package.
