Anden Industrial Dehumidifier A70 Sized for Tents and Small Rooms
Small rooms still produce a surprising amount of water once a full canopy starts transpiring. The Anden A70 is the compact model in Anden's commercial line, a refrigerant dehumidifier rated to remove 70 pints per day at 80°F and 60% RH. It plugs into a 120V outlet and draws 5.8 amps and 645 watts while running at rated conditions. Efficiency works out to 2.1 L/kWh, roughly 4.4 pints per kilowatt-hour. The cabinet measures 12-1/2 x 12-1/2 x 25 inches and weighs 56 lb, so one person can set it on a shelf or a hanging kit. Air enters and leaves the end of the cabinet through 8-inch duct collars. Noise runs about 53 dBA when ducted and 58 dBA sitting in the open. A MERV 11 disposable filter protects a corrosion-resistant aluminum coil charged with R410A. Dehumidifying works on inlet air from 50°F to 104°F, down to a 40°F dew point. Plan for about 2,180 BTU/h of heat added to the room.
Where a 70 Pint Dehumidifier Fits the Grow
Tents and small veg rooms are its home turf. A full tent canopy at lights-off can push RH up fast, and this unit catches that swing before it lands on the leaves. In a veg room, it keeps humidity steady while clones and young plants still need a gentler environment. It also hangs from Anden's hanging kit, freeing the floor for trays and reservoirs. Ducting lets it sit just outside a tent, pulling air in through one port and returning it dry through the other. The control mounts on the front, and it can run dehumidification with ventilation or zoning. The optional A77 remote moves control to canopy height, and Anden's Wi-Fi thermostats send alerts to a phone. The honest limit is capacity, since a large flower room will outrun one unit at this size. There is also no backdraft damper on the outlet, which matters on longer duct runs. The replacement filter is the Anden 5772, and it should come out once it turns gray. The five-year warranty covers every part, refrigeration system included.
Key Features
- Compact 56 lb Cabinet: The small footprint sets on a shelf, hangs from a kit or tucks beside a tent without a second pair of hands.
- 8 in Duct Collars: End-of-cabinet collars let the unit sit outside a tent and serve it through a short flex-duct run.
- Dehumidify, Ventilate or Zone: The front-mounted control can circulate air between cycles or split control across zones.
- Remote and Wi-Fi Options: The A77 remote and Anden's Wi-Fi thermostats move monitoring to canopy height or a phone.
- MERV 11 Filtration: The disposable filter keeps debris off the aluminum coil; the Anden 5772 is the replacement.
- Five-Year Warranty: Coverage includes every part, the sealed refrigeration system among them.
