POLY-VENT®
With our Poly-Vent ventilation system you’ll have an economical alternative
to rack & pinion, and you’ll save in a host of other ways, too. Save on electrical
bills by reducing the use of large fans, save on heating costs because
Poly-Vent’s dead air space provides an effective layer of insulation,
and reduce your maintenance time with fewer moving parts. Able to
accommodate most greenhouse sidewalls, our system provides improved
water drainage. Choose from single-stage or two-stage options to
provide your product with superior ventilation and yourself with savings.
The winds of fortune are blowing in your direction.
Poly-Vent II 36" x 96' package
Full-Closed
Includes frame, Poly-Vent II, end package,
blowers and all hardware.
In the full-closed position,
cool air is prevented from
entering the greenhouse and
the dead air space acts as an
insulated wall.

helping to reduce heating costs

Poly-Vent allows your plants full access to sunlight
for superior growth

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.
Large Gutter Connect
12” Plant Air HAF Fan (VK12) – $159.00
• Gentle Air Movement– ideal fan for any crop in any greenhouse
• Quiet– only 4.5 sones provide a quiet production or retail environment
