VentGuard Plus Panel

The VentGuard Plus is a cost-effective BS6173:2009 and IGEM/UP/19 compliant ventilation interlock, with built-in fan current monitors for the intake and extract fans, however, can still be used with Air DP Switches.

With dedicated interfaces and LEDs for the intake and extract fans, the VentGuard will provide an indication of any ventilation issues, however, will not shut down the gas supply until the ventilation has not been operating for a full 30 seconds to avoid any nuisance tripping.

  • Intake Fan DP, Extract Fan DP, CO2 Sensors, Remote Emergency Stop Buttons

Basic Operation

The VentGuard has a simple key switch operated ON/OFF function and a panel mounted flush emergency stop button to avoid accidental operation.

The panel has interfaces for air DP switches as well as have integral fan current monitors for both the intake and extract. Each channel can be easily setup using the range select jumper (for greater accuracy) and a potentiometer for fine tuning.

If the intake or extract fan are not in operation the panel will still allow gas through until they have been open circuit for a full 30 seconds. As some systems use the valve status to enable the fans this will allow the fans to get up to speed and provide a healthy signal to the VentGuard without any issues.
