The professional industrial dehumidifier HUMBERG HM-481 with a performance of 50 l/24 h speeds up drying of floors, plaster and paints, even after floods. It offers quiet operation at 52 dB, high mobility thanks to large wheels and handles, a hygrostat 20–90% RH, a 24h timer, and the option of continuous condensate drainage (hose included). The eco-friendly refrigerant R290 and automatic defrost ensure reliable operation even in demanding conditions.
High output 50 l/24 h for fast drying
Quickly reduces humidity in construction areas, basements, and after water damage. An airflow of 450 m³/h accelerates drying of plaster and floors.
Easy mobility on-site
Large rear wheels, a sturdy handle, and compact dimensions allow comfortable movement around buildings and in tight spaces.
Continuous drainage with 4 m hose
Choose between a 5.5 l tank and continuous condensate outflow. A transparent hose is included for unattended operation.
The HUMBERG HM-481 is a robust industrial dehumidifier designed for construction sites, basements, warehouses, and post-flood remediation. High efficiency up to 50 liters per 24 hours (30 °C, 80% RH) combined with an airflow of 450 m³/h quickly lowers humidity and shortens drying time. Thanks to the ergonomic chassis, large wheels, and handles, you can easily move it even in confined areas.
The unit is equipped with a precise hygrostat (20–90% RH), a continuous dehumidification mode, a 24-hour timer, and automatic defrost for reliable operation at lower temperatures. Water removal can be handled either into the removable 5.5 l tank or continuously using the 4 m hose (included). The pre-filter is washable and protects the interior from dust.
- Quiet operation ≤ 52 dB – suitable for longer deployments.
- Eco-friendly refrigerant R290 – low GWP, compliant with EU standards.
- Safety – overfill protection, three-minute compressor delay after power outage, status and full-tank indication.
