Always well rolled – VariVent® roller ventilation systems
The VariVent® roller ventilation system from Lock offers all you need:
- top-opening
- bottom-opening
- variable opening from top and bottom
The VariVent® roller ventilation system guarantees high levels of operational safety because they can employ lightweight aluminium tubes with small diameters and lowspeed drives.
All systems are able:
- be operated in the open air
- can be operated with forced synchronisation (patent) to prevent collisions
- can be rolled single or double-format
- can, depending on the length of ventilation required, have their drive located at one end or in the middle
- are easy to convert from manual to power drive
- can be controlled fully automatically, depending on temperature, wind and rain
One single drive is sufficient for a building measuring 100 metres in length, with a maximum opening height of five metres.
