In stock


The DF400F is a medium-sized Dryfast building dryer that is widely used in the construction and rental sectors, as well as in the water damage market for drying flats, for example. This dryer is suitable for rooms up to approximately 400 m³.

This dehumidifier is equipped with a highly efficient rotary compressor and can be transported in all positions and switched on directly (in an upright position). The new DF400F, together with its bigger brother the DF800F, stands out for its incomparably high dehumidification capacity, especially at lower temperatures.

Refrigerant R454C
The DF400F has the new refrigerant: R454C. This is an environmentally responsible refrigerant that we have chosen as an alternative to the R407C refrigerant.

From 1 January 2020, the use of the well-known refrigerant gases R407C and R410A in mobile equipment will be banned on the European market. The permitted value for mobile dehumidifiers as of 1 January 2020 is 150 GWP. R454C has a GWP of 146 and is a versatile and sustainable gas.

Successor to...
This model is the successor DF400 with the 'old' R407C refrigerant gas and of the Dryfast DF300, which is also offered with the type designations: FD30, DH35 and TTK300.
