The best version of economy
Ventair Simpress contains almost all the technology from the TRDn trickle vent but in an economical version.
Reliable automated pressure difference control is based on operation of the aerodynamic aluminium panel – inflowing air makes it drop or raise, controlling the flow rate. This solution ensures constant flow regardless of the weather conditions.
Instead of the aluminium body, this controlled is made of high quality plastic. This gives Simpress the unique frost resistance.
