OKE, more silent than a whisper, is the perfect choice for rooms with strict sound

level requirements and where silence is important. The beautiful curved design

ensures that this classic will fit into the most demanding environments.

Its shape and the throw pattern that is directed at an upward angle make OKE

ideal for installation farther away from the ceiling surface without causing a

feeling of draught. The smooth surface makes the device easy to clean.

Fire safety is an important property in ventilation terminal devices. All Climecon

products are made of sheet steel, making them as safe in a fire as possible. Thanks

to the sheet steel structure, OKE does not burn, which improves fire safety and

increases evacuation time by limiting the uncontrolled spreading of combustion

gases from one room to another.

The series also includes OKE-L, a model specially designed for prisons and closed

wards. OKE is also available for rectangular connections, a good solution when old

vents are replaced by Climecon products creating a better indoor climate.
