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. This makes this convection tubing ideal for practically any greenhouse or structure requiring ventilation or heating.

 

Installation Tips:

 

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. The tube loop extends around the outside of the tube and is clipped to the cable using a snap ring. The hangers should be spaced 7 feet apart. The convection tubing can also be hung with any soft rope or material that won’t rub or puncture the tubing.

 

Suggested Uses for Convection Tubing:

 

  • For ventilation when cooling greenhouses
  • For uniform dispersion of heat from a forced hot-air furnace
  • 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
