Air PD Switch (20-300PA)

Air PD Commercial Kitchen Protection Ancillary Ventilation Interlock
  • Air PD Switch (20-300PA)

We only supply the highest quality air pressure differential switches for increased longevity and reliability, they measure between 20-300Pa. Electrical connections are made by use of two-core cable. Incorporated in each Merlin Gas Interlock system is a 10 seconds Airflow dropout delay. In the event of interruptions to airflow for less than 10 seconds the delay will allow the gas solenoid valve to remain open, preventing nuisance tripping. Should the airflow be interrupted for 10 seconds or more the fan fault LED will illuminate and the gas solenoid valve will close. 

  • Ventilation interlock system which isolates the fuel supply if the ventilation fails
