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.

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
• Can be mounted in any position.
• A range of matched ancillaries is also available.

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

Motor
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.

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