This transparent, polyethylene convection tubing is a highly effective air distribution tool for use in greenhouses, barns, warehouses, workshops and more. It is UV stabilized and designed to hold up against direct sunlight and damp conditions. This convection tubing is extremely lightweight and can be hung inside of practically any structure to allow for even air distribution for heating applications, ventilation purposes, directional airflow and more.A properly installed tube will make full use of the airflow provided by the fan or blower.

Holes are custom punched to one of 5 different hole configurations. The numbers associated with the hole punching options (8/4, 7/5, 9/3) indicate where the holes would line up to a clock face. The tubing is custom cut to specific lengths and comes in multiple diameters to conform to almost any air distribution requirement.

We recommend that tubing be hung from a cable using tube hangers. These hangers do not penetrate the plastic. They consist of a loop of white plastic and a snap ring. These can be purchased here.
