Cleveland Controls AFS-262-121 Air Flow Switch
The Cleveland Controls AFS-262-121 Air Flow Switch is a high-precision, field-adjustable differential pressure switch engineered for proving airflow in HVAC, furnace, and energy management systems. This general purpose proving switch operates within an adjustable set point range of 0.05" ± 0.02" to 2.0" w.c., allowing for granular control in diverse industrial environments. Housing a durable silicone diaphragm and a snap-acting SPDT contact arrangement, the unit is designed to sense positive, negative, or differential pressure with high repeatability. It is rated for 120-277Vac and features 1/2" conduit connections for standard electrical integration. The plated steel housing accepts 1/4" OD metallic tubing via integral compression ferrules and nuts. To ensure accurate sensing, this adjustable air pressure switch must be mounted in a vertical plane. It is compatible with air and combustion by-products that will not degrade silicone, making it a reliable solution for package burner and ventilation monitoring.
Key Benefits- Versatile Pressure Sensing: Capable of monitoring positive, negative, or differential air pressure across a broad set point range.
- Rugged Construction: Built with a plated housing and silicone diaphragm to withstand 1/2 PSI maximum pressure and temperatures from -40°F to 180°F.
- Precision Adjustment: Features a calibrated spring and adjustment screw for fine-tuning the operating set point in the field.
- Safe Electrical Interfacing: Equipped with an enclosure cover to protect screw-type terminals and an integrated 1/2" conduit hub.
- How do I calibrate the set point? Use a digital manometer to confirm the actual set point while turning the adjustment screw; each full turn represents approximately 0.2" w.c.
- Can this switch be mounted horizontally? For proper operation and to meet the lowest specified set point, the diaphragm must be mounted in a vertical plane.
- What tubing is recommended for long runs? Use 1/4" OD tubing for runs up to 10 feet, 1/4" ID for up to 20 feet, and 1/2" ID for runs up to 60 feet to avoid pressure drop interference.
