Fral FDNF33 is a dehumidifier mounted on 4 swivel wheels which, thanks to its robust yet lightweight structure, can be used to remove humidity in particularly damp environments or to dry particularly humid environments.
With a robust galvanized sheet metal structure painted with epoxy resins, the Fral FDNF33 dehumidifier features an efficient polyurethane filter. This high-efficiency filter is washable and easily replaceable.
The portable dehumidifier we are describing has a very large condensate collection tank with the possibility of direct drainage. It is also possible to install a lifting pump in place of the tank, which allows the condensate to be pumped up to a height of 3.5 m from the machine's positioning level.
Fral FDNF33 is equipped with an evaporator coil made of aluminum smooth tubes, which allows for lower energy consumption of the professional dehumidifier, while maintaining very high performance even in conditions of low relative humidity. Hour meter and Hot Gas defrosting with R290 gas.
It has a connector for pump connection - sold separately.

To dehumidify the office, your workspace (industry, craftsmanship) or naturally humid environments such as food laboratories, laundries, bathrooms, swimming pools or to curb condensation mold in archives, libraries, and to control dry air in your shop, Fral FDNF33 is the small and portable dehumidifier you need.
The structure and sheet metal are hot-dip galvanized, then painted with epoxy powders, ensuring high resistance and long-term durability.
The compressor is of the rotary type, mounted on anti-vibration mounts. The evaporation refrigeration circuit is equipped with an aluminum smooth tube coil. The smooth tubes ensure high performance of the dehumidifier, significantly reducing energy consumption even at low relative humidity. For the condenser, the coil is made of copper tubes and aluminum fins; the wide fin spacing of the condenser ensures resistance to dust, long machine life, and easy maintenance.
The condensate collection container is very large and supplied as standard, easily removable. The machine is also prepared for connection to a fixed condensate drain.
The condensate lifting pump of the Fral FDNF33 is designed to replace the condensate collection container and allows the condensed water to be expelled up to a height of 3.5 m from the machine's position. This portable dehumidifier is equipped with an alarm to shut down the dehumidifier in case of pump malfunction. Alternatively, a condensate lifting pump kit is available, easily attachable to the outside of the dehumidifier, equipped with a malfunction alarm and machine shutdown. Both the machine only version and the version with an integrated pump are available.
The fan of the Fral FDNF33 portable dehumidifier is of the axial type, statistically and dynamically balanced. The fan has been designed for long-term durability.
With a washable and easily replaceable polyurethane air filter, the Fral FDNF33 is a high-efficiency filter.
The following tests are performed on the Fral FDNF33:
The microprocessor included with the Fral FDNF33 controls the hot gas defrosting cycles, the compressor timer, and the alarm board. Located on the top of the machine, the control panel is complete and intuitive.



This small and quiet dehumidifier has a single-phase connection of 230 V, with a maximum power of 480 W. The airflow of the Fral FDNF33 dehumidifier is 380 m³/h, with a tank capacity of 8 kg for a maximum dehumidification of 33 L / 24 h.
Suitable for humidity regulation in environments up to 500 m³, the Fral FDNF33 is suitable for drying very humid environments up to 280 m³.
The refrigerant gas used for this professional dehumidifier is R290.

Great for my 100sqm partially underground space that needs constant dehumidification (Translated review)
Generally satisfied, the build quality is in line with what was stated. From the point of view of dehumidification, the machine reaches the set goal but, considering the strong disparity between the maximum declared dehumidification capacities compared to my actual environmental needs, I would have expected it to reach the goal with greater efficiency and speed. (Translated review)
Excellent dehumidifier, immediately put into operation. The impression is that of a solid, well-built machine. (Translated review)
Product conforms to description and function. (Translated review)
I think it is a very good dehumidifier, I hope it lasts several years. (Translated review)
