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® III is a two-stage system that can open partially, allowing some natural air, or can open fully allowing total ventilation. This system works with an optional two-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 36", 48" or 60" heights. Stacking systems are available for taller sidewalls.


How it Works

Two long-lasting squirrel-cage blowers inflate a 3ft 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 blowers operate the ventilator regardless of length.
