Series EK92
EK90 smoke control dampers
Volume flow V, pressure drop
D
p, inflow velocity v
A
With inflow velocities v
A Max
= 10 to 20 m/s, depending on the width and height of the EK90 smoke control damper,
the inflow velocity limits the opening of the smoke control damper. It may need to be reduced temporarily!
Example: The intersection point B = 500 mm with H = 500 mm lies in the field
A Max
= 20 m/s. There is no restriction here!
