EazyVent® delivers top–opening ventilation and the lifting up of rolled sheeting from bottom to top.
The top edge of the fabric is lowered and/or raised by means of a central shaft with cable drum. These special-purpose cables are guided around the sheeting and roll up in a corresponding manner on the cable drum.
When lowering the bottom edge, this creates a loop of cable that starts to rotate the sheeting, causing it to roll up.
