Cleveland DFS-221 Air Pressure Sensing Switch

Cleveland DFS-221 Air Pressure Sensing Switch delivers precise low-pressure control for industrial systems. This SPDT fixed-point air pressure sensing switch activates at a fixed set point of 0.05 in. W.C. (Model 18407), providing dependable, repeatable performance in tight-pressure environments.

Ideal for automation and control circuits, the DFS-221 uses a SPDT output to switch circuits on or off as pressure crosses the set point. Built for reliability, it accommodates compact installations and maintains stable operation across common industrial air handling and pneumatic applications.

• Fixed set point at 0.05 in. W.C. for consistent actuation.
• SPDT output for simple control wiring and versatile logic.
• Durable construction designed for harsh industrial environments.
• Compact footprint that fits tight panels and equipment racks.
• Model 18407 reference supports easy replacement and compatibility.

Integrate the Cleveland DFS-221 into your HVAC, pneumatic, or automation systems to ensure fast, accurate responses to pressure changes and improved process reliability.
