Why Choose the Anden 5807 Duct Kit

If you are running an Anden A320V1 or A320V3 dehumidifier, the 5807 Round Duct Kit is the manufacturer-specified accessory for installations that require placing the unit outside the grow room. Without this kit, the dehumidifier would need to sit inside the cultivation space, which reduces usable canopy area, adds heat load inside the room, and makes filter service more disruptive to the plants.

The duct transitions are fabricated from galvanized steel, which holds its shape under the pressure differentials typical in enclosed climate systems and resists corrosion from the moisture-laden air handled by a dehumidifier. Both the inlet and outlet transitions are sized specifically for 18-inch round duct — the collar size specified for the A320V1 and A320V3 — so the fit is direct without adapters or field modification.

The filter access door on the inlet transition is a practical design feature. In a ducted installation, the inlet transition sits between the duct run and the dehumidifier’s intake port. With the access door, a technician can open the inlet, inspect or change the pre-filter, and close it again without disturbing the duct connection. This matters in production environments where downtime for maintenance should be kept short.

Because this kit is made by Anden for Anden equipment, the transitions are dimensionally matched to the A320 series port geometry. Using a generic third-party collar on a unit this size risks air leakage at the joint, which reduces dehumidification efficiency and can introduce uncontrolled moisture pathways into the room structure.

Best Uses for the Anden 5807 Duct Kit

This kit applies in any installation where the A320V1 or A320V3 dehumidifier is positioned in a mechanical room, hallway, or utility space adjacent to the grow room, and where ductwork connects the unit to the cultivation environment. Specific scenarios include:

• Multi-room commercial grow facilities where a single dehumidifier services one room but is mounted in a shared mechanical corridor. The 18-inch inlet and outlet ducts can run through penetrations in the wall while keeping the unit accessible for service.
• Sealed grow rooms with strict environmental separation where placing equipment inside the room would compromise the sealed boundary or interfere with CO2 enrichment. Ducting the dehumidifier externally keeps the room boundaries intact.
• Rooms where floor space and heat management are critical. A 320-pint-class dehumidifier generates heat during operation. Moving it out of the grow room and ducting only the conditioned air supply back in reduces the in-room thermal load, making it easier for the HVAC system to maintain target temperatures.
• Facilities upgrading from internal to external dehumidifier placement. If an existing A320V1 or A320V3 is already in use and a facility redesign calls for external mounting, the 5807 kit provides the duct interface without requiring a new unit.
• Installations pairing an air filtration pre-filter with the dehumidifier inlet. The filter access door on the inlet transition allows regular pre-filter changes as part of routine maintenance schedules. Paired with a compatible pre-filter, the ducted intake can also help exclude particulates from the dehumidifier’s internal components.

Anden 5807 vs Generic Duct Transition Kits

Commercial-grade 18-inch duct collars and transitions are available from HVAC suppliers, but they are not designed for the port geometry of the Anden A320 series. A generic collar may require field modification — cutting, shimming, or taping — to make a reasonably airtight connection to the unit’s inlet or outlet port. These workarounds add labor cost and introduce potential leak points.

The Anden 5807 kit is engineered to the A320V1 and A320V3 port specifications, so the transitions mount cleanly without modification. The galvanized steel construction matches the durability of the dehumidifier housing. The inclusion of a filter access door on the inlet transition is a feature specific to this OEM kit; generic duct collars do not include one. For operators who want a clean, maintainable installation backed by Anden’s documentation, the OEM kit is the practical choice over generic HVAC fittings.

If you are also managing condensate drainage for the A320, consider reviewing the condensate pump options compatible with large-format dehumidifiers to complete the external mounting setup.

Compatibility

The Anden 5807 Round Duct Kit is designed specifically for two Anden dehumidifier models:

• Anden A320V1
• Anden A320V3

It is not listed as compatible with other Anden models. Operators with A70, A95, A100, or A210 series units should verify the correct kit for those models before ordering. The duct collar size is 18 inches round for both the inlet and outlet, so the connecting ductwork must match this diameter. Standard 18-inch round HVAC flex duct or rigid round duct connects directly to the kit collars.

Facility design should account for the straight duct run requirements at the inlet and outlet to avoid turbulence that would reduce airflow efficiency. Consult Anden’s installation documentation for recommended minimum straight-run lengths before the first elbow in the duct path.

For room-level humidity monitoring alongside your ducted dehumidifier setup, a calibrated controller or sensing device helps maintain target VPD. If your climate setup also requires airflow management, review circulation fan options sized for the room.

Usage Guidelines

The 5807 duct kit is a passive mechanical accessory — it does not have operational settings or controls of its own. Its correct use depends on proper installation and ongoing maintenance of the inlet pre-filter.

Duct sizing: Connect 18-inch round duct to both the inlet and outlet collars. Minimize the number of elbows in each run to reduce static pressure drop. Longer duct runs and additional bends reduce the effective airflow through the dehumidifier; follow Anden’s recommended maximum duct lengths for the A320 series.

Filter service: The inlet transition’s filter access door allows inspection and replacement of the pre-filter without disconnecting the duct. Schedule pre-filter inspections at regular intervals based on the particulate load in the facility’s intake air. A clogged pre-filter restricts inlet airflow and will reduce dehumidifier capacity. Replace pre-filters before restriction becomes visible in dehumidifier performance data.

Duct sealing: Seal all duct joints at the transitions with foil-backed HVAC tape or appropriate sealant to prevent air leakage. Leaks at the inlet allow unconditioned air to enter the dehumidifier stream; leaks at the outlet allow conditioned dry air to escape before reaching the grow room. Both types of leaks reduce system efficiency.

Condensate management: The duct kit handles air routing only. Condensate drainage from the A320 dehumidifier must be managed separately through the unit’s built-in drain connection. Verify the drain line is clear and properly routed before operating the dehumidifier in any configuration.

How to Install the Anden 5807 Duct Kit

1. Prepare the dehumidifier placement. Position the Anden A320V1 or A320V3 in the mechanical space outside the grow room. Ensure the unit is level, has adequate clearance on all sides per Anden’s installation manual, and is electrically connected before attaching ductwork.
2. Attach the inlet duct transition. Mount the inlet duct transition to the dehumidifier’s intake port. The transition is dimensionally matched to the A320 series inlet geometry. Secure according to Anden’s fastener specifications. Verify the filter access door is unobstructed and swings freely.
3. Attach the outlet duct transition. Mount the outlet duct transition to the dehumidifier’s supply port in the same manner as the inlet. Confirm the collar is oriented to align with the planned duct run toward the grow room.
4. Connect the duct runs. Attach 18-inch round duct to each transition collar. Route the inlet duct to draw air from an appropriate source (typically the mechanical corridor or an outside air intake, depending on facility design). Route the outlet duct through the wall penetration into the grow room.
5. Seal all duct joints. Apply foil-backed HVAC tape to every joint at the transition collars and along the duct run where sections join. Confirm there are no gaps or unsealed seams.
6. Install and confirm pre-filter. Open the inlet transition’s filter access door and verify the pre-filter is correctly seated. Close the access door securely.
7. Test operation. Power on the A320 dehumidifier and verify airflow through the outlet duct into the grow room. Check for air leaks at all joints by feel or with a smoke pencil. Confirm the unit reaches its target setpoint within the expected timeframe.
