Polypipe Ventilation has expanded its Silavent Green Line range with the addition of new energy-efficient Axial fans.

Offering one of the lowest specific fan powers available, at 0.22w/l/s, the new axial range exceeds 2010 Building Regulation requirements, using less power and extracting more air, significantly reducing the build-up of condensation and mould.

When in standby mode, the fans use up to 70% less power than other low energy fans which, when combined with the fan's low specific fan power, makes them the most energy-efficient range of axial fans available.

The new Silavent Green Line 100mm axial fans are available in wall or window mountable and in-line versions, and have been designed to directly replace a standard axial fan for maximum convenience. The range also includes safety extra-low voltage (SELV) variants, ideal for installations within the splash area of a shower or bath.

All models are available with a variety of user-friendly optional controls, including timer, pull cord, humidistat and a movement sensor.

Manufactured in UK, the fans come with a two-year warranty as standard. The Silavent Green Line range also features energy-efficient centrifugal Curzon and Mayfair plug-in bathroom extract fans.
