What is polythene ducting ?

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

Why use polythene air ducts ?

suspended ductingActivair air ducting is an adaptable, efficient and economical method of conveying warm or cool air from point to point and distributing it where required

Polythene layflat ducts - SIZES AND QUOTATIONS

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 inflatable duct system

Designing an Activair inflatable ducting system is straight forward providing the following basic rules are adhered to...

Duct kits and installing air ducts

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...

Ducts - frequently asked questions

Answers to the most common questions about Activair ducting

HVAC ducting - uses of inflatable ducts

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

Polythene air conditioning ductsducting

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

Polythene heating ducts

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

Polythene ventilation ducting

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

Air duct for displacement ventilation

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

Plastic ducting for destratification

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...

Polythene ducting for glasshouses

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

Flexible ducts in mushroom farmingducting - mushroom

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

Plastic ducts in temporary structures

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 and ducts

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 and ducts

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

Flexible ducting

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

Flexible air ducts and sick building syndrome - sbs

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.
