Cleveland Controls RFS-4100-078 Air Flow Switch
The Cleveland Controls RFS-4100-078 Air Flow Switch is a high-sensitivity differential pressure switch specifically engineered for HVAC ventilation monitoring and air-proving applications. This unit features a factory-calibrated 0.17" WC actuation point, making it an essential component for detecting low airflow conditions in critical ducts or air handling units. Built with a robust plated housing and a durable silicone diaphragm, the RFS-4100-078 ensures reliable differential pressure sensing across a wide operating temperature range from -40°F to 180°F. The SPDT contact arrangement allows for flexible wiring into control or alarm circuits, while the 1/2" NPT threaded conduit connection facilitates secure electrical integration. Designed for vertical mounting to maintain calibration accuracy, this low air flow switch is a standard-issue HVAC replacement part for technicians requiring precise performance in positive, negative, or differential pressure environments. Its 15-amp non-inductive rating at 277VAC ensures compatibility with most industrial pilot duty loads.
Key Benefits- Precise 0.17" WC Set Point: Factory calibrated for accurate low-flow detection in sensitive HVAC systems.
- Versatile Pressure Sensing: Capable of monitoring positive, negative, or differential air pressure with high repeatability.
- Durable Construction: Features a rugged zinc-plated steel housing and industrial-grade silicone diaphragm for longevity in harsh environments.
- Contractor-Friendly Installation: Standard 1/2" NPT conduit connection and 1/4" quick-connect spade terminals simplify field replacement.
- High Electrical Capacity: SPDT switch rated for 15 Amps at 277VAC, suitable for various control logic and alarm configurations.
Does this switch require specific mounting?
Yes, for maximum accuracy, the diaphragm must be mounted in a vertical plane. Avoid mounting with sample line connections facing upward to prevent moisture or debris accumulation.
Can I adjust the set point in the field?
While the RFS-4100-078 is factory calibrated at 0.17" WC, the RFS-4100 series generally features an adjustable operate range from 0.17" WC to 5.0" WC and a release range from 0.10" WC to 4.7" WC using the internal calibration screw.
What tubing is compatible with the sampling connections?
This model typically utilizes compression fittings designed for 1/4" OD rigid tubing, including copper, aluminum, or plastic lines up to 20 feet in length.
