The SPNO circuit is used to supply compressed air to the unit's tool circuits. The air pressure switch is located in the air line between the compressor and the tool. Switch pressure occurs when incoming line pressure drops below 135 psi (minimum air inlet setting). The purpose of this switch is to provide inverse pressure protection for the tool.

These air pressure switches have been specifically designed to automatically shut off a gas supply during a fall in supply pressure.

Keeping your spa properly pressurized at the correct pounds per square inch (PSI) can be tedious. The York S1-024-35272-000 Fall Close Air Pressure Switch monitors and controls the air pressure inside your spa. It automatically shuts off the circulation pump if water leaks out of your spa or if the air pressure drops below 50 psi, as well as engaging the circulation pump when it should be running.
