Cleveland AFS-222-121 Air Pressure Sensing Switch

Cleveland AFS-222-121 Air Pressure Sensing Switch is a SPDT general‑purpose air sensing switch designed to monitor pressures from 0.05" to 12.0" W.C. for reliable control in HVAC, compressors, and other pneumatic systems.

This compact, rugged device delivers precise pressure sensing with a single-pole double-throw (SPDT) output and easy integration into existing control schemes. The model supports standard air pressure switch applications and is identified by 18469121 for straightforward ordering and replacement.

Designed for easy installation, this air pressure switch features standard electrical connections and robust construction to withstand typical industrial environments. Its SPDT configuration enables switching between two circuits, making it ideal for pressure-activated alarms, fan control, and safety interlocks. With its wide sensing range, it adapts to many system pressures without frequent recalibration.
