PCD636DDEx fans - PowerLine Ex Series

Description

The PowerLine Series® of In-Line Centrifugal Fans is designed for a wide range of duct mounted applications. They are most suitable in commercial and industrial applications where medium to high air pressure is required. They are available in various speed options and 8 sizes, extending from 315 to 710mm diameter.

Features

Robust, yet lightweight galvanised steel construction.
Easy to fit 35mm TDF profile flange connections.
Choice of external rotor or standard direct-drive TEFC motors.
Large choice of speeds available.
Most 3-phase external rotor motors fitted are 2-speed star/delta design.
To improve energy efficiency, motors can be speed-controlled
Motors complying with Ex d, Ex e, Ex nA and Ex tD Standards can be fitted.
Can be mounted in any position.
A range of matched ancillaries is also available.

Construction

Galvanised steel housings with 35mm TDF profile flange connections.
Backward-curved centrifugal impellers. DD impellers are made from aluminium, ER impellers made from high performance injection moulded composite plastic.

Motors

Type - can be supplied with direct-driven external rotor or standard direct-drive TEFC motors.
Electricity supply - single or three-phase to suit a wide range of voltages and frequencies.
Bearings - sealed-for-life, ball.
External rotor motors are fully speed-controllable using electronic or auto-transformer controllers, however Sinusoidal filters are required when a variable speed drive is used.
Standard direct-drive TEFC motors can be single or multi-speed and can be speed-controlled using a variable speed drive.

Internal Thermal Protection

Automatic-reset type is fitted as standard to external rotor motors and is an optional extra on standard frame motors. Air flow tests to ISO5801:2007
Noise tests to BS848:Part 2, 1985

Testing

Air flow tests to ISO5801:2007
Noise tests to BS848:Part 2, 1985

Special Note

Performance curves shown are based on nominal speeds.
As motor speeds may vary from one manufacturer to another, and from one motor type to another, it is possible actual fan speeds may differ and, therefore, the performance of the fan.
For external rotor motor performance refer to Fans by Fantech Selection Program
