Poly-Vent® Natural Ventilation System
Product Description
Improved Poly-Vent natural ventilation system is the cost effective solution for your ventilation needs. Growers with all styles of greenhouses and crops have found it to be the better alternative to expensive rack & pinion vents and leaky roll-up curtain systems. The new frame has improved water drainage and is now designed to be mounted to most greenhouse sidewalls without modification.
Poly-Vent operates using only small blowers that can be thermostatically controlled. Single-stage allows you to fully open or close off your ventilation and two-stage gives you the ability to select different temperatures at which the top and bottom will open or close.
When fully inflated, the dead air space in the Poly-Vent tubes creates an R-Value. Available in 24”, 36”, 48” and 60” nominal heights.
Thermostatically Controlled
Single-stage or two-stage automatic temperature control for optimal control.
UV-stabilized 4-year Poly
Clear, long-lasting poly provides excellent light transmission.
