Curves at different voltages are obtained with a transformer type speed controller.

Performance curves
– Q = Air volume in, m 3 /hr and m 3 /s.
– Ps = Static pressure in mmWG and Pa.
– Dry air at 20ºC and 760 mmHg.
– Performance data in accordance with ISO 5801 and AMCA 210-99 Standards.

Low pressure centrifugal fans
Curves at different voltages are obtained with a transformer type speed controller.

LOW PRESSURE CENTRIFUGAL FANS
CBP Series
Complete low pressure centrifugal range with
forward curved impeller. The range comprises
different versions and sizes of double and
single inlet fans. All these low pressure
centrifugal fans are designed for belt drive
operation.
All the fans are manufactured from galvanised
sheet steel and fitted with impeller manufactured
from galvanized sheet steel.
Additional Information
Mounting feet as accessory allowing 4 different
positions (basic version).
The fan can be supplied with motor and belt
drive mounted.
On request
Belt-drive fan-deck assemblies available with
etiher a fan scroll or separate base frame
mounted motor configurations.
