EK90 smoke control dampers can be used, opened and closed with inflow velocities of v
A
≤ 20 m/s.
The inflow velocities for opening are limited to the values given in the table and in the diagrams:
Nomenclature ⇒ see page 5
500 mm x 500 mm
Example
In these ranges surrounded by the red border, opening is possible at an inflow velocity of v
A
up to 20 m/s with a specially designed electrical connection! ⇒ see page 34
