The Security Relief Vent is purpose-built for evaporative air conditioning systems, allowing you to cool your home securely without leaving doors or windows open.
As the system runs, excess cool air is released into the roof space, which helps your home stay cooler for longer and reduces the energy required to maintain comfort. The Security Relief Vent can be added to new evaporative systems or retro-fitted to existing installations, making it a simple, reliable and secure upgrade for any home.
