Why Choose the Anden 5859 Duct Kit

When running an Anden A710V1 or A710V3 in a controlled indoor environment, placing the dehumidifier unit outside the grow room is often the preferred approach. It frees up floor or overhead space inside the canopy area, reduces ambient heat load from the machine itself, and simplifies servicing — you can change filters and perform maintenance without entering the grow room or disturbing the environment. The Anden 5859 makes that external installation viable by providing the duct interface hardware the units were designed to accept.

What distinguishes this kit from field-fabricated alternatives is precision fit. The 24-inch round collar dimensions are engineered specifically for the A710V1 and A710V3 airflow housings. Mismatched or improvised adapters introduce turbulence at the transition, reduce airflow efficiency, and create potential leak points that let unconditioned air back into the system. The galvanized steel construction handles the condensation-laden environment around dehumidifier ductwork without rusting or degrading over time.

The inlet transition’s filter access door is a practical design detail that grows in importance over the long run. Without it, accessing the filter means dismounting or partially disassembling the inlet section each service cycle. The access door lets maintenance staff check and swap filters in place, which keeps service intervals consistent and reduces the chance of running extended periods with a clogged inlet.

• Precision fit for A710V1 and A710V3: Collar dimensions match the dehumidifier’s designed duct attachment points — no field modification needed.
• Galvanized steel construction: Resists corrosion in humid grow room environments where mild steel or aluminum would degrade faster.
• Integrated filter access door on inlet: Allows in-place filter maintenance without removing the transition section from the duct run.
• Dedicated inlet and outlet transitions: Both airflow paths get properly matched transitions, not just the supply side.
• Manufacturer-supplied hardware: Eliminates compatibility uncertainty that comes with sourcing generic HVAC duct adapters.

Best Uses for the Anden 5859 Duct Kit

This duct kit is purpose-built for one task: connecting an Anden A710V1 or A710V3 dehumidifier to a ducted air distribution system. Within that constraint, it fits several common grow facility configurations.

• External equipment rooms: Large-scale indoor grows that house HVAC and dehumidification equipment in a dedicated mechanical room adjacent to the canopy benefit directly from this approach. The dehumidifier sits outside, ductwork penetrates the wall, and conditioned air is distributed inside without the unit occupying grow space or contributing heat to the canopy zone.
• Multi-room dehumidification layouts: Facilities with multiple grow rooms served by centralized equipment can use the 5859 as part of a larger duct network, tying the A710V1 or A710V3 into a shared supply trunk that feeds individual rooms through dampers and branch lines.
• Retrofit installations: Existing facilities that already run ductwork for heating and cooling can integrate an Anden A710V1 or A710V3 into the existing 24-inch round duct infrastructure using this kit, rather than running a standalone unit inside the room.
• Noise and vibration isolation: Placing the dehumidifier outside the grow area and routing through ductwork helps reduce noise and mechanical vibration in the cultivation space — relevant for facilities where staff spend extended time in the room.
• Clean-room-style environments: Operations that want to keep the number of large mechanical units inside the grow to a minimum for contamination control reasons can use this kit to locate the dehumidifier in a cleanable utility corridor.

For managing in-room humidity directly without ducting, you may also want to consider a replacement condensate pump as part of ongoing dehumidifier maintenance across your facility.

Anden 5859 vs Similar Duct Kits

The Anden 5859 is a dedicated OEM accessory and does not have a direct third-party equivalent sold for this specific purpose. The comparison that matters in practice is between using this kit versus field-fabricating an adapter from generic HVAC components.

Generic 24-inch round duct adapters from HVAC supply houses can be found, but they are not dimensioned to the A710V1 or A710V3 airflow housing. Fabricating a custom adapter typically requires sheet metal work, sealing materials, and testing to confirm airflow and leak rates — adding cost and labor that often exceeds the price of the OEM kit. There is also no filter access point in a field-fabricated inlet section unless specifically designed in.

The Anden 5859 also differs from duct kits designed for smaller Anden models such as the A90 or A100 series. Those units use different collar diameters and housing geometries. The 5859 is specific to the 710-pint A710V1 and A710V3 — Anden’s largest commercial dehumidifier models — and the kit dimensions reflect the greater airflow volume those machines produce. Using a smaller-unit duct kit on an A710 would create a restriction at the transition that reduces dehumidification capacity and may cause the unit to operate outside its rated performance envelope.

Compatibility

The Anden 5859 is compatible exclusively with the Anden A710V1 and A710V3 dehumidifier models. These are Anden’s high-capacity commercial units rated at 710 pints per day. The 24-inch round duct collar is the interface standard for these specific machines.

This kit is not compatible with other Anden models, including the A90, A100, A130, A180, or A210 series dehumidifiers — those units use different collar sizes and housing geometries. Attempting to use the 5859 kit on a different Anden model would require modification that Anden does not support and would likely void any applicable warranty.

For the duct run itself, any standard 24-inch round galvanized or flexible duct can connect to the 5859 transitions. The kit provides the interface hardware between the dehumidifier housing and the duct system; the ductwork, hangers, and sealing materials are sourced separately. Ensure duct lengths and configurations follow Anden’s published guidelines for external installation of the A710 series to maintain rated performance.

If your grow room air management system also involves supplemental airflow equipment, a high-output fan such as those in the Active Air HD pedestal fan line can support air circulation on the room side of the duct system. For pre-filtration of incoming air before it enters the duct run, an inline pre-filter installed upstream of the inlet transition can extend the life of the dehumidifier’s internal filters.

Usage Guidelines

The Anden 5859 is passive hardware — it has no operational settings of its own. Its function is to provide an airtight, correctly dimensioned interface between the A710V1 or A710V3 housing and the external duct system. Once installed, ongoing use involves two main tasks: verifying that connections remain sealed and maintaining the inlet filter on schedule.

Airflow direction: The inlet transition connects to the dehumidifier’s air intake side, drawing room air from the grow space back to the unit for processing. The outlet transition connects to the supply side, delivering conditioned (dehumidified) air back into the room. These transitions are not interchangeable — the inlet unit is the one with the filter access door. Confirm correct orientation during installation and verify airflow direction before commissioning.

Filter access: The filter access door on the inlet transition is designed to allow filter removal and replacement without disconnecting the duct section. The exact filter type used with the A710V1 and A710V3 is specified by Anden in the dehumidifier’s documentation. Maintenance interval depends on the particulate load in the incoming air; in grow rooms with high pollen or dust loads, more frequent inspection is appropriate. A clogged inlet filter reduces airflow to the dehumidifier and degrades dehumidification performance, so establishing a regular inspection schedule is important.

Sealing and connections: All joints between the 5859 transitions and the duct run should be sealed with foil HVAC tape or mastic sealant appropriate for sheet metal ductwork. Avoid standard cloth duct tape, which degrades in humid conditions. Check connections at initial startup and re-inspect after the first 30 days of operation, as thermal cycling can cause minor movement in sheet metal connections.

How to Install the Anden 5859 Duct Kit

Installation of the 5859 duct kit is a sheet metal HVAC task. For large commercial installations, Anden recommends that mechanical contractors or HVAC professionals perform the work. The following steps reflect the general process based on the kit’s design and standard ducted dehumidifier installation practice.

1. Prepare the dehumidifier location: Position the Anden A710V1 or A710V3 in its external mounting location — mechanical room, corridor, or adjacent utility space. Ensure the unit is level and that the duct penetrations through the wall or ceiling are correctly sized for 24-inch round duct.
2. Identify inlet and outlet ports: Locate the air intake and air supply ports on the A710V1 or A710V3 housing. The inlet is the air return side (room air entering the unit); the outlet is the supply side (conditioned air leaving the unit). Confirm orientation against the Anden A710 installation documentation before proceeding.
3. Attach the outlet transition: Connect the outlet duct transition from the 5859 kit to the supply port on the dehumidifier housing. Secure per the manufacturer’s fastening method — typically sheet metal screws at the collar flange — and seal the joint with foil HVAC tape or mastic.
4. Attach the inlet transition: Connect the inlet duct transition (the piece with the filter access door) to the air intake port on the dehumidifier. Again, secure and seal the collar joint. Confirm that the filter access door is accessible and swings open freely after installation — do not position it against a wall or obstruction.
5. Connect the duct runs: Attach the 24-inch round supply and return duct runs to the two transitions. Route ductwork to the grow room penetrations. Minimize bends and elbows where possible; each 90-degree elbow adds resistance equivalent to several feet of straight duct and reduces effective airflow.
6. Seal all joints: Apply foil HVAC tape or mastic to all duct connections, including the transitions, any couplings, and the wall penetration sleeves. Unsealed joints allow humid grow room air to escape into the building envelope, which can cause moisture damage and mold in wall cavities.
7. Install the inlet filter: Before startup, install the appropriate filter in the inlet transition through the access door. Confirm the filter seats flat and the door latches securely.
8. Test and commission: Power on the A710V1 or A710V3 per Anden’s startup procedure. Verify airflow is moving in the correct direction through the duct system — conditioned air into the room, return air from the room back to the unit. Check all sealed joints for air leaks (a smoke pencil or handheld manometer can help). Log the installation date and initial filter condition for maintenance records.
