Cleveland Controls AFS-262-112 Switch

The Cleveland Controls AFS-262-112 is a professional-grade adjustable differential pressure switch engineered for precision monitoring of air flow and pressure in HVAC systems. Covering a set point range from 0.05 to 2.0 inches water column (" w.c.), this SPDT air pressure switch is a standard replacement for detecting clogged filters, proof of flow in fans, and general air monitoring in commercial air handling systems. The unit utilizes a diaphragm-actuated mechanism and features a 1/4" barb connection for secure tubing attachment. Field-adjustable via a calibrated scale, it allows contractors to fine-tune the switching point for high-accuracy performance. Often used as a furnace draft inducer switch or for static pressure monitoring, the AFS-262-112 ensures reliable circuit switching for safety and performance interlocks. Its durable construction and industry-standard footprint make it a go-to HVAC pressure sensor for varied air-side applications.

Key Benefits

• Wide Adjustability: The 0.05" to 2.0" w.c. range provides versatility for low-pressure differential pressure sensing across diverse ductwork configurations.
• Reliable SPDT Contacts: Features Single Pole Double Throw (SPDT) circuitry, allowing for either normally open or normally closed wiring configurations based on system requirements.
• Durable Construction: Built with a high-grade diaphragm and housing to withstand the continuous cycling of commercial HVAC systems.
• Easy Installation: The integrated barbed fittings and mounting holes align with standard industry practices for rapid field replacement.

Common Questions

How do I adjust the setpoint on the AFS-262-112?
Use the adjustment screw on the top of the unit to align the pointer with the desired pressure on the calibrated scale. It is recommended to verify the trip point using a digital manometer during commissioning.

Can this switch be used for both positive and negative pressure?
Yes, by utilizing the appropriate P1 (high) and P2 (low) ports, this switch can monitor positive, negative, or differential pressure in air-handling applications.

Is this compatible with 24VAC or 120VAC control circuits?
The SPDT contacts are rated for standard pilot duty loads in both low voltage and line voltage control circuits; always check the specific amperage draw against the nameplate ratings.
