This pneumatic opener is uniquely designed to open the ventilator even in the worst scenario such as a total failure in the power supply, air supply and piping connectivity. Working with the pneumatic lock it enables the window to meet the stringent sealing requirement.
The product uses main AC power supply and provides a 24VDC output. It is a perfect combination of a regular switch and a RF receiver which makes it ideal for building automation and smart home applications.
This product is designed to control the natural ventilation automatically through the weather sensor inputs. It can also be used to manually switch on/off the ventilator by a wall switch or a handheld remote control.
SHEV controller is designed to accept signals either from the fire alarm system or the day-to-day events to trigger the emergency opening of the smoke ventilators or to activate the natural ventilation in two zones.
