Fans respond to sensor feedback
The QB EC units can be set up to meet specific performance requirements and respond to feedback from such devices as heat, pressure and humidity sensors to adjust air flow as required.
Air Control Industries' QB EC series of slimline fans employ intelligent-motor-driven impellers that permit units to be optimised for efficiency, speed, acoustic performance and cost The intelligent motors harness permanent magnet motor technology with integrated electronic controls

Blow gun could eliminate need for compressed air
Quieter than compressed air guns, the ACI BG-32 blow gun claims to be ten times cheaper to run than compressed air and is safer
Compact blowers more robust than US imports
Compact, powerful and quiet, the new ACI EP10 belt-drive blowers are available with motors from 5.5 through to 18.5kW in standard metric or NEMA frames
This combination allows units to be set up to meet specific performance requirements and respond to feedback from such devices as heat, pressure and humidity sensors to adjust air flow as required.
There is no loss of efficiency at any running speed, unlike conventional AC fans, nor is there any electromagnetic hum or rumble.
The integrated package is also simpler to install and, because it is not limited to synchronous electricity supply (50/60Hz), it can outperform conventional motor/drive alternatives resulting in reduced space demands.
With an operating efficiency of up to 90% and being designed for compatibility with all conventional supply systems, from 12V DC up 480V three-phase, these motors give ACI's QB EC series fans economy of operation plus flexibility of application across their power, flow and pressure ranges.
In addition, with onboard rectification, the fans offer stable performance even where voltage levels fluctuate, which is particularly important where critical ambience control is required.
The intelligent motor unit is protected against over-temperature and over-voltage cut-out, phase failure and locked rotor.
It also has an EMC and line filter. Request a free brochure from Air Control Industries ...
