Supply ventilation systems installed in premises with high requirements to clean air and the noise level.Suitable for limited mounting space.Compatible with Ø 100 up to 200 mm round air ducts.


The casing is made of polymer-coated steel, internally filled with soundinsulating layer.Internal airtight terminal box for power supply.Easy access for filter maintenance.


Iso Box-F series: four-pole asynchronous motor with external rotor and centrifugal impeller with forward curved blades.
Iso Box-F V2 series: two-speed asynchronous motor with external rotor and centrifugal impeller with forward curved blades.
Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced impeller.

Built-in filters provide efficient air filtration. Up to three filters can be installed into the fan.G4 filter provides primary filtration. At the second stage, the secondary filter F8 or HEPA filter H13 can be installed. F8 filter arrests up to 98 % of PM 2.5 dust particles. H13 filter arrest up to 99 % of PM2.5 dust particles, pollen and bacteria. For additional removal of odorss and gases carbon filter can be installed.Quick access to replaceable filters through service panel.


Iso Box-F series: Smooth speed control with an external CDT E1.8 thyristor controller (available upon separate order).
Iso Box-F V2 series: Two-speed control with the external CDP-2/10 speed switch (available upon separate order).


Due to compact design is the ideal solution for mounting in limited spaces, including the space behind false ceiling.Any mounting position.Wall or ceiling mounting with fixing brackets supplied as a standard.
