CBX, CBXR, CBXT, CBXC double-inlet centrifugal fans with belt drive, up to ~62 000 m³/h
Country: · Model: CBX, CBXR, CBXT, CBXC
The centrifugal fans CBX, CBXR, CBXT and CBXC have double-inlet suction and run from a belt, and the larger CBXR give up to 62 300 m³/h. The impeller is galvanized steel with forward-curved blades, and the free shaft comes out on both sides of the casing. These are units for supply and extraction air handling units and ventilation boxes where a large airflow at moderate pressure is needed.

Description
The free shaft on both sides of the casing makes it possible to fit the drive pulley on the more convenient side. The basic CBX series has a galvanized steel casing and impeller, permanently lubricated bearings on rubber dampers and PSB supports included, and on request an SM motor plate with a belt tensioner is added. According to the datasheet the range goes from CBX-1919 to CBX-4747 (7/7–18/18 inches), with a maximum speed of 2500–700 rpm, installed power up to 1.5 kW and an airflow of up to 15 300 m³/h. The air temperature is from −25 to +85 °C. For explosive atmospheres CDXR/ATEX is offered, with an impeller with backward-curved blades and ATEX 2G/2D certification. On the basis of these fans, CJBX ventilation boxes are made with a belt drive in a casing of Magnelis steel (corrosion category C5 to ISO 12944), as well as in versions with an aluminum profile, sound insulation and filters.
How to choose
For small airflows CBX is enough, and for large sizes and loads CBXR from CBXR-15/15 to CBXR-30/28 is taken, with a reinforced frame and rigid bridge-type supports. When a ready-made unit is needed, CBXT is chosen, which comes with a motor, pulleys, belts and guards. CBXC has a rigid cubic frame that reinforces the casing. If the rotational speed has to be changed, a VSD converter is selected for the fan.

FAQ
What is the maximum airflow of the CBX and CBXR fans?
For the basic CBX up to 15 300 m³/h according to the datasheet, and for CBXR up to 62 300 m³/h.
Why does the free shaft come out on both sides of the casing?
The drive pulley can be fitted on either side, depending on where the motor is located and how it is more convenient to tension the belt.
Can the speed of the CBX fan be adjusted?
Yes, the rotational speed is changed by the belt transmission or a VSD converter. The maximum speed in the CBX range lies within 2500–700 rpm depending on the size.
How does CBXR differ from CBX?
CBXR has a reinforced frame and rigid bridge-type bearing supports, so it is used for large sizes from CBXR-15/15 to CBXR-30/28.
Up to what temperature do the CBX fans work?
The air temperature is from −25 to +85 °C.
