This transparent, polyethylene convection tubing is designed to be 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 as well as any 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.

 

Each piece of convection tubing has holes punched in an orientation that best suit the needs of the user. 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. So the 3/9 hole orientation directs air in opposite directions where a 7/5 hole orientation is a more directed approach.

 

A properly designed tube will make full use of the airflow provided by the fan or blower and helps to distribute the air evenly down the length of the greenhouse. Punch positions can be varied as shown in the above image to best suit the ventilation/heating needs of the user. 

 

The tubing is custom cut to specific lengths and comes in multiple diameters to conform to almost any air distribution requirement. It is also custom hole-punched to one of 5 different hole configurations.

 

 

Suggested Uses for Convection Tubing:

  • For ventilation when cooling greenhouses

  • For improved mixing of air in greenhouses
  • For the introduction of dry air into greenhouses
  • To provide gentle streams of ventilation air instead of harsh blasts of air
  • To heat selected areas of a greenhouse when the whole house does not need heat
