Resideo AP4508 Pressure Switch
The Resideo AP4508 Pressure Switch is an industrial-grade differential air pressure switch designed for precision monitoring in HVAC and pneumatic systems. Engineered with a Single Pole Double Throw (SPDT) switch configuration, this component provides versatile control logic for high-limit or proof-of-flow applications. It features a broad operating range from 0.17" ± 0.05" water column to 5" water column, allowing technicians to fine-tune setpoints for specific system requirements. The unit is rated for a 1/2 PSI maximum operating pressure, ensuring safety and stability in low-pressure air handling environments.
For seamless field integration, the AP4508 utilizes 1/4" quick connect electrical terminals and dual-size 1/4" and 5/16" barbed connections for flexible tubing installation. Its gold-plated contacts enhance electrical reliability, supporting 15 Amps resistive at 277 VAC or low-current 10 mA at 5 VDC circuits. This adjustable air switch is a standard solution for airflow proving and filter monitoring, protecting equipment by preventing operation outside of intended pressure parameters.
Key Benefits:- Broad Setpoint Range: Adjustable from 0.17" to 5.0" WC for precise differential pressure sensing across various duct sizes and equipment types.
- Dual Hose Compatibility: Features combination barbed fittings (1/4" and 5/16") to accommodate standard polyethylene tubing without extra adapters.
- High Electrical Capacity: Rated for up to 15A resistive at 277V, making it suitable for direct control of small motors or integration into 24V pilot duty circuits.
- Reliable SPDT Logic: Enables the technician to wire for either "break on rise" or "make on rise" signal logic, fitting diverse HVAC control wiring diagrams.
- How do I adjust the setpoint? The setpoint is adjustable via the internal dial to meet specific water column (WC) requirements for your application.
- Can this be used for proof of airflow in furnace applications? Yes, the Resideo AP4508 is commonly used as a safety interlock to prove draft in combustion and ventilation systems.
- What is the maximum pressure this switch can handle? The housing is rated for a maximum operating pressure of 1/2 PSI; exceeding this may damage the internal diaphragm.
