Due to it's size this box is excellent capable for midsized rooms and systems.
The isolation consists of shredded foam plastics and makes this small fan-box so low-noise. The uneven with compressed sound proofing lined box swallows almost every little sound of the working snail-shell fan, which is already a quite silent device. Despite the isolation, the high effort of ca. 2000m³/h is possible.
To be able to hang the fan-box under the ceiling, you recieve four hooks and elastic rings. To affix the hooks, there are already four threads installed. Now, nothing can go wrong!
To install the fan-box right, according flanges have already been attached to the in- and out-holes of the box. You just have to fix the air hose to the holes.
Tip: The wider the hose - the lower will be the air drag inside it. A low air drag entails a low noise.
With a speed controller for your fan you can decrease energy consumption and controll the operation of the snail-shell fan.
The dimensions of this fan-box are:
Length x width x height = ca. 55 x 55 x 55cm
in-holes: 2 x ca. 25cm
out-hole: ca. 30cm
Capacity: ca. 2000m³/h
