About AS2

AS2 is a stylish yet robust 240V fan designed for effective humidity control operation within kitchen environments. All AS2 kits include a remote AUTOSTAT smart humidity controller which can be placed away from the fan. This fan is particularly useful when it is important for the humidity sensor to be located away from the fan for optimal humidity control.

AS2 is supplied in a kit form for either wall, window or double glazing installation (150mm/6 inch back spigot).

The AS2 includes a removable stainless steel grease filter that can be easily removed for cleaning and is dishwasher proof.

AS2 Wiring Diagram

General Notes on Fan Installations

The fan position should be as far as practical from the main source of air replacement. This is to avoid short- circuiting of the airflow. The AS2 has a 150mm spigot and sleeve (which is supplied) to an external grille (supplied as standard in brown. Other colours are available upon request at time of order). The ducting hole through the wall requires a minimum of a 5 degree downward slope to the outside. For a window installation a 155mmØ hole is required. For a wall installation a 160mmØ hole is required.

The AUTOSTAT should be located on an internal wall at a high level close to the moisture source or between the moisture source and external doorway. The top edge is to be 50 – 100mm down from the ceiling and it should be positioned clear of corners > 150mm, clear of any protrusions, cupboards etc. The AUTOSTAT should be positioned away from heat source and not within 1000mm of a radiator, a grill or hob

If the room/ dwelling contains a fuel burning device such as a gas boiler with a non-balanced flue, it is essential that there is enough replacement air to prevent fumes being drawn down the flue where the fan is extracting.

And for the Specifier…

The AS2 is supplied with a 2 speed extractor fan with override switch, and can be installed through the kitchen wall /or window. The fan will include a motor of not more than 25 watts extracting at no less than 220m3/h on high speed. The fan has automatic shutters, a remote Autostat humidity control and remov- able stainless steel filter.
