Description
Unlike the axial jet fans THT/IMP, CI has a low casing height, so it suits rooms with low ceilings and dense service routing where an axial jet fan with silencers does not fit. The casing is made of sheet steel, and the impeller has backward-curved blades of strong sheet steel. The outlet jet entrains the surrounding air and directs smoke and gases toward the extraction points, so a branched duct network is not needed. A service switch of the IAT series is built into the fan, and supports are included. Motors are class H for continuous duty S1 and emergency duty S2, with ball bearings, IP55, one or two speeds (versions 4T and 4/8T), supply 230/400 V 50 Hz. Air temperature in S1 mode is up to +40 °C, up to +50 °C in a hot climate, and in emergency mode 300 °C or 400 °C for two hours. One of the models at 1395 rpm gives 6050 m³/h. Models CI-CO, CI-CO/EC and CICO/LP with IE5 EC motors are intended for daily ventilation, not for smoke extraction.
How to choose
CI is chosen when ceiling height is limited and the axial THT/IMP with silencers does not fit. The 4T version has one speed and 4/8T has two, so the second can be given to daily ventilation. If larger diameters and thrust are needed, look at TUNEL JET FAN up to 1800 mm in diameter.

FAQ
How does CI differ from an axial jet fan?
By its low casing height. CI fits under a low ceiling where an axial jet fan with silencers does not.
What is the maximum airflow of CI?
About 9340 m³/h per the datasheet, sizes CI-50 – CI-100.
At what temperature does CI work in fire mode?
300 °C or 400 °C for two hours per EN 12101-3. In normal S1 mode the air temperature is up to +40 °C.
What supply and protection does the CI motor have?
Three-phase 230/400 V 50 Hz, class H, IP55 protection, version 4T or 4/8T.
