Vent-Axia sets the standard in ventilation. In 1936 Joe Akester invented the world's first electrically-operated, window fan and Vent-Axia was born. Today, we are every bit as forward-thinking, original and dedicated as we were then. That's why the Vent-Axia brand is not just the clear leader in the sector, but also the chief innovator and leader in energy-saving, lo-carbon products and systems. http://www.vent-axia.com/
