The Gasbye Gasbye 4500 dehumidifier delivers 115 pints daily capacity at 80°F and 80% humidity, making it perfect for large spaces up to 4500 square feet. This powerhouse unit features Energy Star Most Efficient 2024 certification with ID 3417537, ensuring maximum efficiency while keeping energy costs down.
Built with 5-tier copper coil construction weighing 19.5kg, this robust dehumidifier operates at just 45dB noise level - quiet enough for living areas. The unit offers triple drain flexibility including a 1.7-gallon tank, 5-foot hose and garden hose adapter.
Smart features include automatic reset after power outages, washable filter and adjustable humidity control. Operating at 500 watts with 12,600 cubic feet per hour airflow capacity, it efficiently manages humidity in basements, garages and large rooms.
The Gasbye DryPrime-50-B uses 5 rows of copper tubes compared to fewer rows in typical dehumidifiers. This extensive copper configuration improves heat exchange efficiency, allowing it to extract 115 pints daily at optimal conditions versus 52 pints for standard units. The Energy Star Most Efficient 2024 certification (ID: 3417537) confirms it meets the strictest efficiency standards, which many competitors cannot achieve due to insufficient copper usage.
The unit operates at 45dB, making it relatively quiet for medium to large spaces. This noise level won't disturb normal activities like watching television, having conversations, or relaxing. The specially designed quiet compressor makes it suitable for living areas, bedrooms and open-plan spaces where noise levels are important, whilst still delivering powerful dehumidification across 4500 square feet.
The dehumidifier offers triple drain flexibility to suit different installation needs. You can use the built-in 1.7-gallon tank for manual emptying, connect the included 5-foot drain hose directly to floor drains for continuous operation, or attach the provided garden hose adapter for extended disposal using your own garden hose. This flexibility eliminates frequent tank emptying and allows for permanent installation in basements or utility rooms.
The automatic reset feature ensures the dehumidifier resumes its previous settings when power returns after an outage. You don't need to manually restart or reconfigure the unit - it automatically continues operating at the humidity level and fan speed you had set before the power interruption. This maintains consistent humidity control and protects your home from moisture damage even during power disruptions.
This unit is designed for spaces up to 4500 square feet, making it suitable for large basements, garages, living rooms and commercial spaces. The 12,600 cubic feet per hour airflow capacity ensures effective air circulation throughout large areas. The high extraction rate of 115 pints daily at optimal conditions means it can handle significant moisture loads in sizeable spaces.
The unit operates at 500 watts and works on standard 115-volt household outlets with 15-amp capacity. Despite its powerful performance, the Energy Star Most Efficient 2024 certification ensures it uses electricity efficiently. The 5-tier copper coil construction maximises dehumidification per watt consumed, keeping running costs down even during continuous operation in large spaces.
Maintenance is minimal with the washable filter that can be cleaned regularly to maintain optimal airflow. The robust 19.5kg construction with quality components means fewer mechanical issues. The 1.7-gallon tank is easy to remove and clean, whilst the included drain hose and garden hose adapter allow for maintenance-free continuous drainage when connected to permanent drainage systems.
Performance varies with room conditions, but the unit can extract up to 115 pints daily at 80°F and 80% humidity. At normal household conditions (76°F and 60% humidity), it maintains 73 pints daily capacity. Even at cooler conditions (60°F and 60% humidity), it extracts 50 pints daily. The powerful airflow of 12,600 cubic feet per hour ensures rapid air circulation and humidity reduction throughout large spaces.
