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.

G4 filter provides primary filtration.Fine filtering with an electrostatic filter.Quick access to replaceable filters through service panel.


Iso Box-F ES series: four-pole asynchronous motor with external rotor and centrifugal impeller with forward curved blades.Iso Box-F ES 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 turbine.

Electrostatic filter enables purification of air from fine dust and soot, spray, smoke and other particles with the size 0.01 microns and less.Max. filter cleaning efficiency 98 %.The electrostatic filters rely on gravity of oppositely charged objects.The polluted air stream flows through the spray charging unit for the particles ionization.Ionized particles are moved by the airstream and accumulated on the collecting plates which are oppositely charged.
The filter cleaning interval depends on the inlet air pollution density and may vary from 7 up to 21 days.The filter cleaning interval is determined by the visual inspection of the filters.Vacuum cleaning is allowed.


Iso Box-F ES series: smooth speed control with an external CDT E1.8 thyristor controller (available upon separate order).Iso Box-F ES 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.
