DESCRIPTION

Professional-Grade Greenhouse Ventilation With Ultra-Low Power Usage

The Western Harmonics 2051-HG is a high-velocity 20-inch hanging fan engineered specifically for home greenhouses, commercial growers, and high-tunnel operations. It delivers the airflow of a full-size 120V industrial greenhouse fan — but runs on safe, efficient 12-volt DC power.

Whether you power it from the grid, a 100W solar panel, or a portable power station, the 2051-HG provides reliable, high-volume airflow while using one-third the energy of a traditional 120V exhaust or circulation fan.

This makes it one of the most cost-effective and versatile greenhouse ventilation solutions available today.

Why Greenhouses Need This Fan (Home, Commercial & High Tunnel)

1. Home Greenhouses (6×8, 8×12, hobby structures)

Home growers need airflow that prevents:

heat buildup

stagnant air pockets

mold & mildew

humidity spikes

plant stress

The 2051-HG solves all of these with:

3,300 CFM of high-velocity airflow

Directional hanging design for canopy-level circulation

Zero-cost solar operation during peak heat hours

Safe low-voltage power around misting systems and moisture

It’s the simplest way to stabilize temperature and humidity without increasing your electric bill.

2. Commercial Greenhouses (multi-bay, propagation houses, retail houses)

Commercial growers need:

consistent airflow

low operating costs

safe equipment around irrigation

long daily runtimes

scalable systems

The 2051-HG delivers:

⅓ the power usage of 120V fans

Cooler motor temperatures for long runtimes

Low-voltage safety around wet floors and metal frames

Solar compatibility for reducing operational overhead

MC4 connectors for fast, modular installation

This fan is built for real agricultural environments — not consumer-grade hobby equipment.

3. High Tunnels & Hoop Houses

High tunnels trap heat fast. Growers need:

strong directional airflow

low-cost continuous ventilation

equipment that tolerates dust, humidity, and temperature swings

The 2051-HG excels because:

It can run directly from a 100W solar panel during peak heat

It uses only ~60 watts when grid-powered

It moves 3,300 CFM, ideal for long tunnel structures

It’s metal-built, not plastic

It’s safe around drip irrigation, misters, and condensation

This is one of the few fans that works equally well in off-grid, semi-grid, and full-grid greenhouse operations.

Three Ways to Power the 2051-HG

1. Plug Into the Grid (Most Common)

Using a standard 12V 8A power supply, the fan becomes a super-efficient grid-powered greenhouse fan.

Uses only 60 watts

Costs up to 66% less to operate than 120V fans

Runs cooler and quieter

Perfect for long daily runtimes

2. Run Directly From the Included 100W Solar Panel

In full sunlight, the panel powers the fan at zero cost.

Ideal for:

high tunnels

remote greenhouses

off-grid homesteads

power-outage protection

Solar + 12V DC = free airflow during the hottest hours of the day.

3. Use a Portable Power Station

Compatible with most 12V DC outputs (Jackery, EcoFlow, Bluetti, etc.).

Perfect for:

mobile greenhouses

seasonal structures

temporary grow setups

emergency ventilation

Low-Voltage Safety Advantage

Greenhouses are wet, humid, and metal-framed — the worst environment for 120V AC fans.

The 2051-HG runs on 12V DC, which means:

reduced shock risk

safer around irrigation and misting

no high-voltage wiring

safer for workers and animals

ideal for metal structures

This is why low-voltage systems are the standard in agricultural environments.
