PowerLine Ultra Series – PUD634DD

The PowerLine Ultra Series® of In-Line Mixed-Flow Fans is designed for a wide range of duct mounted applications. They are most suitable in commercial and industrial applications where medium pressure is required. They are available in various speed options and 9 sizes, extending from 250 to 630mm diameter.

Construction
Galvanised steel housings with 35mm TDF profile flange connections.
Mixed-Flow impellers are made from high performance injection moulded composite plastic material.

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.

Testing
Air flow tests based on ISO5801
Noise tests based on BS848:Part 2, 1985, or ISO13347-3

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.
