OEM duct kit — model-matched for the LG508C and LG880C R32 units.
The Leizig Duct Kit (SKU 31800049) is the factory-matched ducting accessory for the LG508C (508 pt/day) and LG880C (880 pt/day) R32 dehumidifiers. It enables remote installation — place the unit outside the grow room and duct conditioned air in and humid return air out — without improvised adapters or fit issues.
The Leizig Duct Kit is a factory-engineered accessory designed specifically for the LG508C and LG880C dehumidifier models — the R32 refrigerant variants in the Leizig commercial lineup. It provides the transition hardware needed to connect round ductwork to the unit's inlet and outlet ports, allowing you to install the dehumidifier outside the cultivation space and move conditioned, dry air to where it's needed via dedicated supply and return runs.
Remote installation matters in commercial builds where floor footprint, noise management, or cleanroom-style air separation is a priority. With the duct kit in place, humid return air is drawn from the canopy zone through an intake duct, dehumidified, and delivered back into the room through a supply duct — the unit itself sits in a mechanical corridor, above-ceiling space, or adjacent utility room. This is the same architectural approach used in purpose-built licensed cannabis and hemp facilities running high-density flower canopies around the clock.
This duct kit is matched to two specific units in the Leizig lineup — verify your model number before ordering. The LG508C removes 508 pints of moisture per day at 6.8 pints/kWh with a 1,500 CFM blower and a 15,200 BTU/h heat load. The LG880C steps up to 880 pints per day at 6.36 pints/kWh with a 2,250 CFM blower and a 22,000 BTU/h heat load. Both run R32 refrigerant — a lower-GWP (675) alternative to R410A that delivers comparable performance with reduced environmental impact and better thermodynamic efficiency per unit of refrigerant charge.
Both units support MERV-8/13 filtration, RS485 MODBUS integration for building automation and environmental controller tie-in, and are rated for operating temperatures from 56°F to 95°F. They ship with multiple installation configurations — hoisted, ceiling, wall-mount, and floor cabinet — and the duct kit is what unlocks the remote-ducted configuration in ducted ceiling or mechanical-room installs.
Dehumidifier duct kits are not universal. The inlet and outlet collar geometry, port sizing, and transition hardware are designed to the specific unit's blower housing and airflow path. A generic or mismatched collar creates static pressure irregularities that reduce effective airflow below rated CFM, which directly cuts into moisture removal performance — a 508 or 880 pt/day unit undershooting capacity in a sealed flower room has real consequences for VPD stability and mold pressure.
Using the OEM Leizig kit ensures collar geometry matches the unit's ports, transitions are sealed without improvised tape or fabrication, and the airflow path stays consistent with the unit's rated performance at its installed static pressure. If you are running the base LG508 or LG880 (R410A variants) rather than the LG508C or LG880C (R32 variants), this kit is not the correct part — contact us to confirm compatibility before ordering.
In high-density commercial cannabis and hemp facilities, placing dehumidification units inside the flower room adds heat load, noise, and occupies floor or ceiling space that could otherwise be used for canopy. A ducted setup positions the unit in a mechanical corridor or above-ceiling chase, separating the noise and heat from the cultivation environment while still delivering humidity control directly over the canopy zone.
Overhead ducted return pulls humid air at canopy level — where transpiration load is highest — rather than relying on passive room mixing. Paired with the LG508C's or LG880C's RS485 MODBUS output, the dehumidifier integrates with facility environmental controllers for automated RH setpoint management across multi-zone builds. The duct kit is the hardware that makes this architecture possible on Leizig's two highest-capacity R32 units.

This kit is spec'd for the LG508C and LG880C — the R32 refrigerant variants. The base LG508 and LG880 use R410A and may have different port geometry. Do not assume cross-compatibility. If you are unsure which variant you have, check the model label on your unit and contact us before ordering.
Yes — that is exactly what this kit enables. The duct kit provides the inlet and outlet transition hardware so you can run dedicated supply and return duct runs between the unit and the cultivation space. This is a common approach in commercial builds where noise reduction and floor/ceiling space optimization inside the flower room are priorities.
The refrigerant designation distinguishes the specific model variant — LG508C and LG880C use R32, while the base models use R410A. Duct kit fitment is matched to the physical unit, so confirming you have the C-series model ensures you are ordering the correct kit. R32's lower GWP (675 vs. R410A's 2,088) also makes these units more compliant with evolving refrigerant regulations.
The duct kit provides the transition collars that attach to the unit's inlet and outlet ports. Standard round flexible or rigid commercial duct connects to the collars. Duct sizing should be matched to the unit's airflow — the LG508C moves 1,500 CFM and the LG880C moves 2,250 CFM, so undersized duct runs will increase static pressure and reduce effective airflow. Consult your HVAC contractor for duct sizing based on your run length and configuration.
The Leizig Duct Kit provides the transition and collar hardware that interfaces the unit to your ductwork — it does not include flexible or rigid duct runs. Duct material is sourced separately based on your install's length, routing, and static pressure requirements.
