Description
The VentGuard Plus is a cost-effective ventilation interlock system designed to comply with BS6173 and IGEM/UP/19 standards. It features built-in fan current monitoring for both intake and extract fans, while also remaining compatible with air differential pressure (DP) switches.
Commissioning is quick and straightforward thanks to its push-button setup. Simply run the fan at minimum and maximum speeds, set the values with a button press, and choose the desired tolerance level.
With dedicated interfaces and LED indicators for both intake and extract systems, the VentGuard Plus provides clear alerts for ventilation faults. To prevent unnecessary shutdowns, the system includes a built-in delay, only isolating the gas supply if a fault persists for more than 30 seconds.
