F5 Fans Greenhouse Circulation Fan - 20-in - 1/3 HP - 5,470 CFM - 115V/230V

Even Horizontal Airflow for Greenhouse Climate Control - 20-in Fan

Stagnant air leaves hot spots, trapped humidity and stressed plants. This circulation fan sets up a gentle horizontal airflow pattern, often called a racetrack pattern, that keeps air moving from ceiling to floor and spreads heat and moisture evenly. A 1/3 HP motor turning at 1725 RPM drives 5,470 CFM through a 20-in fan.

The 20-in size suits mid-sized greenhouses, barns, warehouses and larger indoor cultivation rooms. Growers covering a bigger footprint can place several units around the space to build one continuous airflow loop.

Key Features & Benefits

• 5,470 CFM airflow — moves a large volume of air to even out temperature and humidity.
• Deep-guard design — supports high airflow with low noise and added safety around the blades.
• Powder-coated steel guard — resists wear and corrosion in humid environments.
• Ceiling mounting bracket and power cord included — the 5 ft cord and bracket come with the fan, so installation needs fewer extra parts.
• Variable speed control compatible — lets you tune airflow to the conditions in your space.

Who Should Use F5 Fans Greenhouse Circulation Fan

Greenhouse operators, commercial growers and home gardeners who want steadier temperature and humidity through vegetative growth and flowering will get the most from this fan. It also works in barns and warehouses that need constant air movement.

About F5 Fans Greenhouse Circulation Fan

Frequently Asked Questions

Q: What does HAF mean?
A: HAF stands for Horizontal Air Flow. Fans arranged this way push air in a circular racetrack pattern around the space, so air keeps moving from ceiling to floor instead of settling in layers.

Q: What voltage does this fan use?
A: It is rated for 115V or 230V. Amp draw is 3.8A at 115V and 1.9A at 230V. Confirm your supply voltage before wiring.

Q: Does it come with a power cord and mount?
A: Yes. A power cord and a powder-coated steel ceiling mounting bracket are included.

Q: Can I run it with a variable speed control?
A: Yes, the fan is compatible with variable speed controls. This lets you lower airflow when conditions allow and raise it when heat or humidity builds.

Q: How is a circulation fan different from an exhaust fan?
A: A circulation fan moves air within a space to even out conditions. An exhaust fan removes air from the space and brings in outside air. Many greenhouses use both.
