Air Handling Units - Airbox F40

Casing design

Units in the F40 series have a frameless construction. The Airbox F40 is a low-cost alternative to the S40 series, with small sizes up to a unit size of 13Q (outside dimension 1340 x 1340 mm). All panels in the F40 series are double-skinned, with an inside sheet, outside sheet and insulation in between. The insulation thickness of the side and top panels is 40 mm. The bottom panel of flat units with operation from underneath is also fitted with 40 mm thick insulation. In all other variants, the insulation thickness of the bottom panel is 60 mm. The inner sides of the device are completely smooth. In the standard variant, galvanised steel sheet with a thickness of 1.0 mm, is used for the panels. Alternatively, at additional cost, it is possible to select sheets in galvanised steel with plastic coating, stainless steel V2A (1.4301) or aluminium AlMg3 separately for the outside and inside. The standard colour of the plastic coating is light grey RAL 7035. Other RAL colours are also possible. The rock wool, used as thermal and acoustic insulation, is non-flammable and is partly glued onto the double-skin panel. The F40 units are suitable for meeting the hygiene regulations of VDI 6022.

Base frame

F40 air handling units can be fitted with a folded base frame with heights from 100 mm to 500 mm, made from 3 mm thick galvanised steel sheet.

Panel connection

The panels of the F40 series are designed to be offset in relation to one another at their connection points. They are screwed on from the outside at opposite sides in each case along the outside edges, meaning that a highly stable connection is achieved. The screws are located completely within the panel in order to provide the best possible thermal and visual properties. The openings in the outside sheet required for the screw connection on the inside are tightly sealed with UV-resistant plastic caps.

Module connection

Gusset plates are mounted on the casing corners at the factory in order to connect the modules. The supplied tapped screws tighten the modules to the opposite gusset plates. The U-profiles, which are also supplied, produce a completely smooth module joint. The screw connections of the module joint are covered with plastic caps in order to achieve a high hygiene quality.
