Description
The box reduces the noise radiated into the room and simplifies installation and maintenance. The unit is connected to ducts with flanges and works in a horizontal or vertical position. Inside there is an axial fan with an impeller of glass-fiber-reinforced polyamide-6, and models 100-4T-15 and 100-4T-20 have a cast aluminum (AL) impeller, which is also available for other sizes on request. The standard airflow goes from the motor to the impeller, and on request a reverse direction, fully reversible impellers and a vertical axis are possible. The class F motors run on ball bearings, IP55 (single-phase of sizes 45–56 IP54), with one or two speeds, and a single-phase 230 V 50 Hz or three-phase 230/400 V 50 Hz supply up to 4 kW and 400/690 V 50 Hz above 4 kW, with an ambient temperature from −25 to +50 °C.
How to choose
The versions have 4 and 6 poles, and the performance is close to that of the HCT duct fans of the corresponding size, but the box adds sound insulation and motor protection. As a supply unit it is used in the KIT BOXSMART and KIT BOXPRES PLUS pressurization kits to EN 12101-6. For operation directly in the fire zone, the series CJTHT with a similar layout and F400/F300 certification is intended. It is used for supply and extraction in industrial and public buildings, car parks, metro stations and technical rooms where a large airflow at moderate pressure and reduced noise is needed.

FAQ
What is the box in CJHCH for?
It reduces the noise radiated into the room and protects the motor, and the removable inspection covers simplify maintenance.
Can CJHCH be installed vertically?
Yes, the unit works in both horizontal and vertical positions and is connected to ducts with flanges.
What are the power and airflow of CJHCH?
Motors by model code from 0.25 to 15 kW, airflow in the table about 71 850 m³/h, sizes 56–100.
What is the fan impeller made of?
Glass-fiber-reinforced polyamide-6. Models 100-4T-15 and 100-4T-20 have cast aluminum (AL), which is also available for other sizes on request.
Is CJHCH suitable for operation in the fire zone?
No, for that there is the series CJTHT with a similar layout and F400/F300 certification. CJHCH is used as a supply unit in pressurization kits to EN 12101-6.
