Cleveland Controls FS-751-112 Air Flow Switch
The Cleveland Controls FS-751-112 Air Flow Switch is a heavy-duty, fixed set-point differential pressure switch engineered for HVAC air proving and energy management applications. Designed for maximum reliability in duct heaters and ovens, this SPDT air pressure switch triggers on a pressure rise of 0.05" ± 0.02" w.c.. The unit features a plated housing that protects the internal diaphragm and snap-acting switch, making it an ideal choice for contractors requiring a non-adjustable, tamper-proof solution in restricted-access areas.
Built to withstand demanding environments, the FS-751-112 is compatible with air and combustion byproducts that do not degrade silicone. It supports positive, negative, or differential pressure sensing via dual 1/4" barbed connections, facilitating easy integration with flexible tubing. With an electrical rating of 15 Amps non-inductive at 277 VAC and a mechanical life exceeding 100,000 cycles at 0.5 psi, this Cleveland Controls air switch ensures long-term performance in commercial and industrial air handling systems.
Key Benefits:
- Fixed Set Point Precision: Factory-set at 0.05" w.c. rise to prevent field tampering and ensure consistent fan proving cycles.
- Versatile Pressure Sensing: Capable of monitoring positive, negative, or differential air pressure for comprehensive system safety.
- Durable Construction: Features a rugged plated housing and a silicone diaphragm designed for 100,000+ operations.
- Contractor-Friendly Installation: Includes 1/4" barbed sample line connectors and screw-type terminals with cup washers for secure HVAC wiring.
- Safety Certified: UL and CSA approved for use in professional HVACR and combustion control environments.
Common Questions:
Can the FS-751-112 be mounted in any orientation?
To maintain the specified 0.05" w.c. trip point, the switch must be mounted vertically. Mounting the diaphragm horizontally or with connectors pointing upward may alter the calibration due to the weight of the internal components.
What type of tubing is compatible with the barbed fittings?
The 1/4" barbed connectors are designed for flexible slip-on tubing. For runs up to 10 feet, 1/4" OD tubing is standard; for longer runs up to 60 feet, larger ID tubing is recommended to minimize signal lag.
Is this switch suitable for high-temperature exhaust?
The FS-751-112 has an operating temperature range of -40°F to 180°F. It is compatible with combustion byproducts as long as the temperature at the switch remains within this range and the media does not degrade silicone.
