Raypak 007158F Vent Pressure Switch 0.40" W.C.

The Raypak 007158F is a vent pressure switch designed to monitor and regulate air pressure in pool and spa heating systems. This safety component is calibrated to 0.40 inches water column (W.C.) and ensures proper venting by detecting adequate draft pressure before allowing the heater to operate.

Key Features:

• Pressure rating: 0.40" W.C. (inches water column)
• Genuine Raypak OEM replacement part
• Safety switch prevents heater operation with inadequate venting
• Direct replacement for multiple Raypak heater models
• Ensures compliance with proper combustion air management

Cross-Reference Numbers:

• 302-2342
• 500-100-kit
• IS20360-5458

This pressure switch is a critical safety component that protects against potentially dangerous backdrafting conditions. When the vent system develops adequate negative pressure (draft), the switch closes to complete the control circuit and allow heater startup. If proper venting is not detected, the switch remains open and prevents ignition.
