Poly-Vent natural ventilation system

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 also acts as an insulator. Available in 24”, 36”, 48” and 60” heights.

    • Thermostatically controlled
      Single-staged or two-staged automatic temperature control for optimal control.

    • Rugged construction
      Built tough with a 24-gage galvanized frame for uears of use.

    • UV-stabilized 4-year poly
      Clear, long-lasting poly provides excellent light transmission.

Rugged construction
24 gauge galvanized frame is built to stand up to even the harshest environments and give your greenhouse years of natural ventilation.
Full-closed
In the full-closed position, cool air is prevented from entering the greenhouse and the dead air space acts as an insulated wall.

Single or two-stage ventilation
Poly-Vent II (single-stage) or Poly-Vent III (two-stage)
give you the choice of full or partial venting for even greater control.

Full-open
In the full-open position, Poly-Vent allows complete, natural and free movement of outside air into the greenhouse. There are no expensive fans or cooling pads required.
Control blowers
One or two long-lasting squirrel-cage blowers
operate the ventilator regardless of length.
Mix and Match
For maximum sidewall ventilation mix and match
single + two-stage stacked systems to any height.
Improved design
Sheds water away from your structure.
