Description

Poly-Vent® is an innovative alternative to inefficient and cumbersome roll-up vents. Heavy-duty, clear, UV-stabilized polyethylene opens from the top down without any moving parts except for small blowers. It can be thermostatically controlled and acts as an insulator with six inches of dead air space when inflated. Poly-Vent provides an energy efficient, airtight seal the full length of the vent opening. Start giving your plants all the fresh air they need. Poly-Vent® II is a single-stage system that can be either fully closed or fully open, allowing total ventilation. This system works with an optional one-stage thermostat.

Standard Features

  • Use as side wall vents on all types of greenhouses.
  • Has no moving parts except small blower.
  • Opens from top down eliminating cold air dump on plants.
  • Use as upper vents on sawtooth greenhouses.
  • Full-open position admits maximum light.
  • Insulates as it seals.

Dimensions

The frame can be easily retrofitted to existing structures and is available in 24", 36", 48" or 60" heights. Stacking systems are available for taller sidewalls.


How it Works

One long-lasting squirrel-cage blower inflates a 2ft to 5ft high series of poly-tubes to create an airtight wall. When the greenhouse gets too warm, an optional thermostat opens the poly wall for natural ventilation. The blower operates the ventilator regardless of length.

  • worked fine!
    The retrofit was some 3 days drilling Etc, the product worked as advertized, only complaint was the noise of the unbalanced squrill-cage fan. I used it for two years, had to install fencing wire to keep the critters out, clen the vent pillow end sockets so they sealed well and had to keep constant vigilence durring hard snows for iceing creatink leaks from weighting down the pillow top as the snow melted off the wall. I tried skirting the top with Galv. sheet metal and it helped but not a total fix.
