EK90 smoke control dampers
Description, properties, sizes
Fire classification
EI 90 (vedw - hodw - i ↔o) S1500 Cmod HOT400/30 MA multi
•EI90 Fire resistance period of 90 minutes
Installation:
ve d in and on horizontal smoke extraction ducts.
ho d in and on vertical smoke extraction ducts.
ve w in rigid walls and in flexible walls.
ho w in rigid ceilings.
i ↔ o Fire exposure has been verified on both sides.
• S1500 For smoke extraction systems with operating pressures
between
1500 Pa negative pressure and 500 Pa overpres-
sure (pressure class 3).
Smokeproof at up to 1500 Pa differ-
ential pressure.
• Cmod 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.
Widths B: 200 mm to 1500 mm
Heights H:: 200 mm to 800 mm
Lengths L: 350 mm to 850 mm
All dimensions are available in 5-mm
increments!
Installation with horizontal or vertical damper
blade:
• in rigid walls and ceilings, ≥100 mm thick and
≥ 450 kg/m³ bulk density.Wet installation with
mortar or a dry installation with mineral wool
≥ 100 kg/m³ are possible.
• in metal stud walls, ≥95 mm thick, with or with-
out mineral wool ≤ 100 kg/m³ inside.
• on and between horizontal or vertical smoke
extraction ducts.
Can be connected:
• in single or double-sided arrangement on
smoke extraction ducts with fire resistance
period,
• in single-sided arrangement on smoke extrac-
tion ducts without fire resistance period,
• in single or double-sided arrangement on pro-
tective grille
