Raypak 008171F Normally-Open Blower Pressure Switch 1.10" Water Column

The Raypak 008171F Blower Pressure Switch operates as a fundamental safety element that monitors air pressure levels before ignition events in HVAC systems and pool heater systems. The switch operates at 1.10" water column pressure to activate its normal open state to prevent burner operation under airflow problems. The system achieves better reliability and efficiency through normally opened auxiliary contacts. The equipment operates, in heaters and similar equipment to prevent improper ventilation, which protects against overheating and prevents combustion failure. This pressure switch protects equipment longevity through safe operating conditions and enhances both energy efficiency and performance consistency, which makes it vital for heating systems safety and efficiency.
