For systems designed only for smoke extraction and also for
combined ventilation systems that was as heating, ventila

tion and air conditioning systems.Intermediate damper blade
positions for volume flow adjustment are permitted (modula-
tion mode).
The service life is verified by 20,000 weight-loaded cycles.
•
HOT
The smoke control dampers close and open again at least
after 30 minutes of fire exposure at 400°C.
•
MA
Closed smoke control dampers can be opened after 25 min
-
utes of full exposure to fire (> 800°C).
•
multi
The smoke control dampers may be used between fire com-
partments (multi) and in individual areas (single).
Maintenance-free
EK90 smoke control dampers EN 12101-8 – Series EK92 –
With casing and damper blades made from abrasion-proof, safe,
corrosion-resistant calcium silicate that is suitable for higher
temperatures. The edge protection profiles are made from gal
-
vanized steel and include connection holes.
Opening and closing is carried out by means of stainless steel
shafts using electric motor drives for 24 V AC/DC or 230 V AC
even when the fan is running and at inflow velocities of up to
20 m/s.
Special seals without any additional stops allow for large free
cross-sections and thus extremely low pressure drops and
sound power levels.
