Polyethylene Convection Tubing


Our Greenhouse Poly Convection Tubes have long been used to provide improved air quality and HVAC control for greenhouses and livestock barns.

Available in either 4 or 6-mil plastic, the clear polyethylene is protected with a strong UV inhibitor. Our plastic is formulated for maximum light penetration and for durability in a greenhouse environment. Each tube is guaranteed to support the cubic feet / minute output of the fan for which it is designed. If there is a problem, the tubing will be replaced immediately.

A properly designed tube will make full use of the fan's output by distributing air effectively down the length of the greenhouse. If we know the length of the house and the diameter of the fan, we can custom design the tube.

Convection Tubing is available in diameters of 12", 16", 18", 20", 24", 30", and 36".  4-mil. rolls up to 1500ft and 6-mil. rolls up to 1000ft.

Punch position can be varied as shown below to provide the best possible air flow for each situation.



To order, select your MIL, diameter, and Punch Position preference then enter the installed length of each tube in the Custom Length field below and add to cart.  Repeat for each additional tube required.

Edge Punch and Staggered Punch add $0.10/ft.

For additional customization requests, including hole size and spacing, you may add a note to each tube at checkout, or simply reach out to our design staff at info@ken-bar.com
