MAIN FEATURES

The “CDV” range of centrifugal fans is designed for the transfer of medium volumes of chemical contaminated air

streams. Great care was paid when designing the “CDV” range of centrifugal fans. These fans are robust, easy to

maintain. All components are expertly CNC cut and machined, resulting is a high quality and aesthetically pleasing

product. All impellers are dynamically balanced ensuring the lowest vibration possible. All fans in this range are

available with PTFE vapour seals ensuring no escape of harmful contaminated air.

MATERIALS

The materials for all parts in contact with chemical corrosive air streams are made from thermo-plastics. The “CDV”

range is available in three different thermo-plastic constructions for differing chemical resistant and temperature

applications.

PP-H - A+ chemical resistance - MAX 70°C

PVDF - A+++ chemical resistance - MAX 100°C

PVC - A+ chemical resistance - MAX 40°C

All vapour seals are constructed using PTFE while the seal housing will match the material of the fan. All fasteners and

pedistals are made from Stainless Steel. Mechanically joined components are sealed using chemically resistant

O-rings.

MOTORS

All “CDV” fans come standard with standard efficiency motors; however various options of motors are available

depending on the customer's preference.

Options available on request (but not limited to):

- Zone 1 Div. 1 motors

- Epoxy coated motors

- Premium efficiency motors

- Additional thermistor installed on motor

APPLICATIONS

Customers that want to move chemical contaminated air streams with temperatures that do not exceed 100C, flow

rates up to 18 000 m3/hr and a maximum pressure of 1800 Pa will select the CDV range for their installation.
