Anden A70 Commercial Grade Dehumidifier — 70 Pints/Day 120VAC MERV 11

Precision Humidity Control for Small Grow Spaces — Built for Cultivation, Backed by 5 Years

Maintaining accurate humidity in a small indoor grow environment is harder than it sounds. Fluctuating moisture levels drive disease pressure, disrupt Vapor Pressure Deficit targets, and create the conditions for mold that ruins a crop fast. The Anden A70 Commercial Grade Dehumidifier is engineered specifically for cultivation environments — not repurposed from a residential product line — removing up to 70 pints of moisture per day with onboard digital controls that give growers direct, precise command over their environment.

Running at 645 watts with an energy factor of 2.1 liters per kilowatt hour, the A70 delivers efficient moisture removal without the energy overhead of oversized units. The self-sealing MERV 11 filter captures up to 95 percent of airborne particles, protecting both crops and internal components from dust and debris common in grow environments. A positive pressure drain eliminates the need for gravity-fed drainage setups, simplifying installation in spaces where floor drainage isn't conveniently located.

The A70 supports optional remote control integration for growers running automated environmental management systems. It can be installed suspended from the ceiling, freestanding on a surface, or ducted for remote placement outside the grow space — accommodating a wide range of room configurations. The unit replaces the previous Anden A70 model and is backed by a 5-year warranty.

Key Features & Benefits

• 70 Pints/Day Removal Capacity — Sized for micro and small grow environments, the A70 removes up to 70 pints of moisture per day to maintain stable relative humidity and consistent VPD targets throughout the growth cycle.
• 645W Energy-Efficient Operation at 2.1 L/kWh — Delivers effective moisture removal at low wattage, keeping operating costs manageable in spaces where every circuit matters.
• MERV 11 Self-Sealing Filter — Captures up to 95% of airborne particles, protecting plant canopies and internal components from dust and debris. The self-sealing design prevents air bypass and simplifies filter changes.
• Positive Pressure Drain — Actively discharges condensate rather than relying on gravity, allowing flexible drain line routing even when drains are not located below the unit.
• Onboard Digital Controls with Clear Display — Set and monitor target humidity directly from the unit face. Compatible with optional remote control accessories for integration into automated environmental management systems.
• Three Installation Options — Suspend from overhead structure, stand freestanding, or duct for remote placement outside the grow space — giving installers flexibility across a wide range of room layouts and ceiling heights.
• 5-Year Warranty — Anden's commercial-grade build quality is backed by a 5-year warranty, providing long-term confidence in environments where equipment downtime is costly.

Who Should Use the Anden A70

The A70 is the right dehumidifier for cultivators managing micro grows, small dedicated grow rooms, propagation spaces, and single-tent setups where a full-size industrial unit would be oversized and inefficient. It is equally well-suited for nursery growers, greenhouse compartments, and indoor facilities managing a single room or zone. Operators who want precise onboard control, cultivation-specific engineering, and the confidence of a multi-year warranty will find the A70 a practical and reliable choice.

Frequently Asked Questions

How does the Anden A70 compare to a standard home dehumidifier for grow use?

The Anden A70 is purpose-built for cultivation environments, not adapted from residential product lines. It uses a positive pressure drain system, a MERV 11 self-sealing filter suited for grow room particulate loads, and controls designed around humidity setpoint management rather than simple on/off cycles. Home dehumidifiers typically lack the airflow patterns, filtration, and control precision that commercial grow operations require for consistent VPD management.

What room size is the A70 designed for?

Anden rates the A70 for micro and small indoor grow environments. Actual effective coverage depends on canopy size, grow lighting heat load, irrigation volume, and room construction. As a general guideline, the A70 performs best in environments producing moderate daily moisture loads — typically single-room or single-tent setups. Growers managing larger spaces or higher transpiration loads should evaluate the A100 or A130.

What is VPD, and how does the A70 support it?

Vapor Pressure Deficit (VPD) is the difference between the moisture the air can hold at a given temperature and the moisture it actually holds — a key metric for optimizing plant transpiration and nutrient uptake. The A70 continuously monitors humidity and temperature to support stable VPD management. Pairing the A70 with compatible environmental controllers allows growers to automate humidity response based on real-time VPD readings rather than simple relative humidity setpoints.

Can the A70 be ducted to run outside the grow room?

Yes. The A70 supports ducted installation, allowing the unit to be placed outside the grow space with inlet and outlet ducts routed through the wall. This is common in setups where noise reduction, heat management, or space constraints inside the grow room make internal placement impractical. An optional duct kit accessory is available for compatible Anden models.

What is the cord length and plug type on the A70?

The A70 comes with an 8-foot 120VAC grounded plug cord. It operates on standard single-phase 120VAC power at 60Hz, drawing 5.4 amps — compatible with a standard 15-amp household or commercial circuit. No special electrical infrastructure is required for installation.
