12" Plant-Air® HAF circulation fan

Eliminate circulation worries with Horizontal Air Flow (HAF) fans

  • Gentle Air Movement—ideal fan for any crop in any greenhouse
  • Quiet—only 4.5 sones provide a quiet production or retail environment
  • Small size—easy placement, better clearance
  • Maintenance Free—motor never needs oiling
 
Schaefer Plant Air® HAF circulation fan
Use these circulation fans to implement Horizontal Air Flow (HAF) patterns throughout
the greenhouse. The HAF system places small circulation fans strategically in the greenhouse creating a ‘race-track’ air flow pattern. This reduces humidity and moisture condensation, improves carbon dioxide availability and equalizes temperature. The Plant Air fan is no-maintenance. The totally enclosed motor never needs oiling and uses heavy-duty moisture resistant bearings for long-life.

Advantages of Horizontal Air Flow
Air stratification is practically eliminated. The entire air mass is mixed to provide even temperatures from crop to gutter.

The corners of the greenhouse are “scrubbed” by the moving air, eliminating those hot and cold spots.

Moisture condensation on the plants is reduced, aiding in disease control.

Carbon dioxide utilization is improved by keeping fresh air moving around the plants.

Humidity within the plant canopy is reduced which lowers the occurrence of leaf disease.

Humidity within the greenhouse is not reduced, but is spread throughout the greenhouse.
