Energy Efficient Fans

Building regs for new build properties require very energy efficient fans, as some run continually at a very low rate.
All the fans here are a selection from our energy saving extractor fans range that have special EC/DC motors, meaning they are much more efficient (in terms of power used per amount of air moved) than the current AC motors.
Over the next few years AC motors will slowly be phased out in favour of these new types of energy saving fans, in all applications.
Upgrading to EC fans offers the following key benefits.:
Up to 70% reduction in energy consumption, integrated & infinitely variable speed control and payback periods as low as 2 years.
They are normally directly interchangeable with their inefficient predecessors, allowing for simple replacement with minimal disruption.

Update: Below is a selection but there are now Energy Efficient versions of most legacy AC fans. Please ask if what you require is not shown.
Whilst they are currently a little more expensive they will soon pay for themselves with reduced running costs and often once you subtract the cost of the controller (Most if not all EC fans have in-built speed controllers) can be a similar price.
