Leizig LG195-VFD 120v

What the LG195-VFD Is

The Leizig LG195-VFD is a commercial-grade refrigerant dehumidifier designed specifically for professional cultivation environments. At 195 pints of moisture removal per day, it sits at the entry point of Leizig's commercial lineup — but it carries the line's highest efficiency rating at 7.0 pints per kWh, meaning you're pulling more moisture per dollar of electricity than any other unit in the Leizig range.

The VFD designation indicates a variable frequency drive on the blower motor, giving the unit precise airflow modulation rather than fixed-speed operation. That matters in a grow room: you can dial airflow to match actual transpiration load rather than running full blast 24/7, reducing both noise and energy consumption during lighter demand periods.

The LG195-VFD runs on 110–240VAC single-phase power at 50/60 Hz, which means it plugs into standard US commercial circuits without requiring a panel upgrade or step-down transformer — a meaningful advantage for operators installing into existing rooms or retrofitting spaces not wired for 208V or higher.

Who This Unit Is Built For

The LG195-VFD is the right size for dedicated flower rooms, veg rooms, or humidity-sensitive dry rooms in small-to-mid-scale licensed cannabis and hemp facilities — any environment where a residential or contractor-grade dehumidifier has been struggling to keep up with transpiration load at canopy peak.

It's also well suited as a zone unit in larger operations. Rather than relying solely on a single high-capacity unit to cover an entire floor, some cultivation directors run one LG195-VFD per room or zone, giving them isolated humidity setpoints for different growth stages running simultaneously.

Operators transitioning from residential-grade equipment into purpose-built commercial dehumidification will find the LG195-VFD hits the right combination of capacity, efficiency, and electrical accessibility. It doesn't require specialized electrical work, it installs in four different mounting configurations, and it integrates directly into the environmental controllers already running your facility.

Key Features for Commercial Cultivation

MERV-11/13 filtration is standard on the LG195, which is a step above what larger Leizig units run. This dual-rated filter catches harmful microorganisms and particulates before they recirculate to the canopy — relevant in any facility where airborne pathogen pressure is a concern. Filter inspection is recommended every 30–60 days, and the design supports quick field replacement without tools.

Every unit in the Leizig lineup — including the LG195-VFD — ships with RS485 MODBUS compatibility and a remote dry contact input. This means direct integration into environmental controllers without a separate relay board or third-party adapter. Set your RH targets in your controller; the LG195 responds. The 3/4" NPT drain port connects directly to facility drainage for continuous gravity-drain operation, eliminating manual condensate management entirely.

Galvanized steel construction with specially treated surface coatings protects against the corrosive, high-humidity environment inside an active grow room. Combined with a vibration-dampening structural design that keeps the unit below 73 dB(A), the LG195-VFD is built to run continuously on 24/7 duty cycles without the bearing wear and noise escalation that typically shortens the life of lighter-duty units.

Installation and Integration

The LG195-VFD supports four mounting configurations: floor-standing, wall-mount, ceiling-suspended, and overhead hoisted. Ceiling suspension is particularly practical in dense canopy rooms where floor space is tight — suspend the unit overhead and pair with ductwork for targeted moisture removal across defined canopy zones without sacrificing grow area.

Because the unit accepts any single-phase power supply from 110V to 240VAC, it integrates into virtually any existing electrical panel without modification. For operators running a 120V supply in a smaller dedicated room, the LG195-VFD is the most electrically accessible Leizig unit available — no electrician needed to step up voltage.

MODBUS integration means the LG195-VFD can be supervised and logged alongside all other environmental equipment on the same network. If your environmental controller supports RS485, the LG195 appears as an addressable device — RH data, run state, and alarms all available in your existing dashboard. For facilities running multi-room monitoring or building automation, this eliminates a standalone humidity controller from the equipment list entirely.
