Cleveland Controls RFS-4001 Pressure Switch Reliable Performance: Heavy-duty construction resists

Reliable Performance: Heavy-duty construction resists fatigue and maintains set-point accuracy across a wide range of flow rates

this O-ring is fabricated from high-grade elastomers

Use a multimeter to verify that the MFD readings are within the +/- 5% or 6% tolerance specified on the label

using a genuine York heating system component ensures the flame pattern remains stable and doesn't lead to nuisance trips at the flame sensor

Ensure the system is depressurized or handled according to safety protocols if the drain is not auto-actuated

Cleveland Controls RFS-4001 Pressure Switch Reliable Performance: Heavy-duty construction resistsThe Cleveland Controls RFS 4001 Pressure Switch is a high performance airflow proving switch engineered for precision in HVAC and Energy Management systems. Built with a rugged plated housing, this differential air pressure switch utilizes a silicone diaphragm and a snap acting SPDT switch to monitor air velocity and pressure drops across filters or coils. It features a broad adjustable set point range from 0. 17" w. c. to 2. 0" w. c., allowing
