    This item ships to the lower 48 states ONLY, there is no international shipping available.


    4  mil Convection Tubing is ideal for cooling greenhouses, uniform dispersion of heat from a force hot-air furnace, for improved mixing of air in greenhouses, and so much more. Ken-Bar's poly convection tubing is available in 4 & 6 mil. The polyethylene is clear and is protected with a strong ultraviolet inhibitor. The formulation of the plastic is designed for maximum light penetration and for durability in a greenhouse environment.

    Custom Punching - Ken-Bar provides proper diameter holes and spacing that conform to the fan manufacturer's specifications. A properly designed tube will make full use of the fan's output by distributing air evenly 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. Punch position can be varied as shown below to provide the best possible airflow for each situation.

    Guarantee - Each tube is guaranteed to support the cubic feet/minute output of the fan. If there is a problem, the tubing will be replaced immediately.  The 4-mil tubing is guaranteed for 1 year.
