Dehumidifier Dedra DED9904, 1000 W, 230 V, 50 Hz, 45 kg, Black

Dedra DED9904 is a portable building dehumidifier designed for residential and light commercial applications. With a rated power of 1000 W for 230 V / 50 Hz supply and a weight of 45 kg, this black unit reduces indoor humidity to help prevent mold, dampness and moisture-related damage in basements, utility rooms, storage areas and drying spaces. The dehumidifier uses R290 refrigerant and features an airflow of 500 m³/h and a high extraction capacity suitable for larger rooms.

Advantages

The Dedra DED9904 delivers up to 90 litres of moisture removal per day under standard test conditions (30°C, 80% RH), enabling relatively rapid drying of wet rooms and construction sites. Its 500 m³/h airflow supports efficient dehumidification across areas commonly between 210 and 310 m². The unit includes an LCD display and a 24-hour programmer for easier control, an auto-defrost function for reliable operation in cooler conditions, a washable mesh filter for basic air filtration and transport wheels plus a rubber tube option for continuous drainage. The use of R290 refrigerant reduces environmental impact compared with many traditional refrigerants.

Suitable for

• Drying plaster, freshly painted walls and construction finishes
• Removing moisture after flooding or leaks in basements and utility rooms
• Maintaining humidity control in storage and processing areas
• Short-term dehumidification on renovation and building sites

How to use

Place the Dedra DED9904 on a flat, stable surface with clear airflow around the intake and outlet areas. Connect the unit to a 230 V / 50 Hz outlet and set the desired humidity or runtime using the LCD display and 24-hour programmer. For continuous drainage during extended operation, attach the supplied rubber tube to the drain outlet and direct the hose to an appropriate drain point. Empty the internal collection container if used, and clean the washable mesh filter periodically to maintain airflow and efficiency. Use the auto-defrost function when operating in lower ambient temperatures; consult the user instructions for recommended operating ranges and safety precautions.

Usage recommendations

For effective and safe operation, ensure adequate ventilation of the room, position the dehumidifier away from heat sources and direct walls, and avoid obstructing air inlets and outlets. Regularly inspect and clean the washable filter and check the drainage connection during prolonged use. When using the unit on construction sites or after flooding, operate the dehumidifier continuously until humidity targets are reached and monitor progress via the display.
