AIR PRESSURE SWITCH SAPS72F SHINEAU

Product Overview

The Shineui SAPS72F Air Pressure Switch is a safety control device used in gas burners and industrial combustion systems, where monitoring air or gas pressure is critical to safe operation. It operates by positive pressure, negative pressure, or differential pressure, allowing it to serve as a pressure-sensing safety interlock across a range of burner configurations. The switch is built for low-pressure sensing, with supplier listings stating it operates at a low pressure of 0 to 30mmH2O, with the set point adjustable to the pressure required by the installation. (Note: a closely related Shineui model, the fixed-type SAPS-70F, is documented with a slightly different range — 4 to 30mmH2O — so it’s worth confirming the exact range on your specific unit’s nameplate or datasheet before specifying it for a job.) The SAPS72F is sold and distributed as a burner safety component, used as a safety device in positive pressure or differential pressure systems to sense gas or air pressure within gas burner and industrial gas systems, and is commonly stocked alongside comparable pressure-limit controls used on industrial gas trains.
