Polythene ducting is the most economic and efficient method of distributing warm
and cold air. A typical polythene ducting system consists of one or more inflatable polythene ducts
suspended overhead from steel wires
 Activair
air ducting is an adaptable, efficient and economical method of
conveying warm or cool air from point to point and distributing it where required
Activair layflat ducting is manufactured from lightweight polythene tubing,
compounded to our own special formula for maximum elasticity, flexibility, toughness, and resistance to
splitting and tearing
Designing an Activair inflatable ducting system is straight forward providing the
following basic rules are adhered to...
Activair air ducts are quick and easy to install. They can be laid on the floor,
under benching or suspended overhead using a duct kit. For optimum air distribution when installing Activair
air ducts the following guidelines...
Answers to the most common questions about Activair
ducting
Activair hvac ducting is the most flexible and adaptable method of moving air
from point to point, and distributing it where required. Activair hvac ducting
has been used with warm, temperate and cold air in heating, ventilation and air
conditioning systems for over 40 years
Activair air conditioning ducts are the most cost effective and efficient method
of conveying cold air from point to point, and distributing it where its needed. Activair air conditioning
ducts are manufactured from lightweight polythene, and are compatible with most air conditioners,
evaporative coolers and fans
Activair heating ducts are the most adaptable and efficient method of
distributing and diffusing warm air. Activair heating ducts are compatible with
most warm air heaters and air handling systems, and are used in place of metal
ductwork to improve air distribution and reduce temperature gradients
Activair ventilation ducting is the most economic, accurate and efficient method
of conveying and diffusing fresh air. Manufactured from polythene tubing,
Activair ventilation ducting is used in a wide range of industries and
applications
Displacement ventilation uses low velocity cool air diffused
from an air duct at floor level to replace warmer polluted air. The air duct
provides occupants with a continuous supply of fresh, clean air while
forcing smoke, fumes and pollution upwards
When air is heated it rises, this is why in buildings with high ceilings, it
feels cold at floor level and hot in the roof space. The effect is called
stratification, and causes...
Activair has been supplying polythene ducting for use in
glasshouses and polytunnels since the 1950’s. Our polythene ducting reduces
temperature gradients, and so improves plant quality, yields and profitability
To produce mushrooms profitably precise control of the mushrooms environment is
vital. The flexible ducts must not only be able to distribute air evenly to prevent temperature gradients,
but to also ensure air is not blown directly onto the crop
Temporary ducting is the most efficient and economical way
to distribute air in marquees, portable buildings, polytunnels, large tents etc. Temporary ducting
diffuses warm and cold air throughout the structure, reducing temperature gradients, and stopping
pockets of stagnant, cold or hot air from forming
Fabric ducting is used to distribute warm and cold air in factories, warehouses,
cold stores, gymnasiums, etc. often as a direct replacement for traditional sheet metal ducts. Compared to
metal ducting fabric ducting is lighter and less expensive
Textile ducting is widely used for cold air distribution in food preparation
areas, cool rooms, stores etc. However for hygiene reasons it has to be regularly removed, laundered
and re-fitted, which is a time consuming and expensive process
Activair flexible ducting is lightweight, economical and durable. It is suitable
for use in high, medium and low pressure ventilation, heating, air conditioning, and fume extraction
systems. Activair flexible ducting is puncture and tear resistant, and withstands repeated flexing
without damage
Sick building syndrome - SBS is characterised by occupants complaining of
illnesses which appear to have no relationship other than occupancy of the same building, area or room.
