Schaefer Versa-Kool High Velocity Greenhouse Fan, 20"

Horizontal Air Flow Circulation Fan for Greenhouses, 20in

A greenhouse with still air develops temperature and humidity pockets that a single point-source fan can't fix on its own. The Schaefer Versa-Kool is a Horizontal Air Flow (HAF) fan that moves air in a steady, coherent racetrack pattern, mixing the space from ceiling to floor to help even out heat and humidity.

This 20 inch model suits a mid-size greenhouse structure or section that needs stronger circulation than the smaller models provide.

Key Features & Benefits

• Horizontal Air Flow design — creates a racetrack airflow pattern that mixes air from ceiling to floor.
• Deep guard design — lowers noise and adds safety without choking off airflow.
• Powder coated steel construction — built for durability and corrosion resistance, including the mounting bracket.
• Mounting bracket and power cord included — ships ready to install across a range of mounting options.
• Variable speed and misting kit options — available separately to fine-tune cooling.

Who Should Use the Versa-Kool Fan

Greenhouse growers who need consistent heat and humidity distribution across a structure or section, without excess noise, will get the most use out of a Versa-Kool fan sized to that space.

Frequently Asked Questions

What does HAF stand for?

HAF stands for Horizontal Air Flow, a circulation pattern that mixes air from ceiling to floor in a racetrack shape rather than simply pushing air in one direction. That mixing is what helps even out temperature and humidity pockets across a greenhouse.

Does this fan come with a mounting bracket?

Yes, a powder coated steel mounting bracket and power cord are included. The fan supports a range of mounting configurations depending on the greenhouse layout.

How do I adjust the fan speed on this unit?

Variable speed controls are available separately as an option. That lets a grower fine-tune circulation rather than running the fan at a single fixed speed.

Is a misting kit available for this fan?

Yes, misting kits are available separately for added evaporative cooling. Pairing one with the fan combines air movement with active cooling.

What's the warranty on this fan?

This fan carries a two year warranty and is made in the USA with matched motors and blades for consistent circulation. That domestic assembly and component matching is standard across the Versa-Kool line regardless of fan size.
