air conditioning ductsActivair air conditioning ducts --------------

Air conditioning ducts

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 air conditioning ducting is used to:overhead air conditioning ducts

Improve cold air distribution - Without air conditioning ducting the effect of a fan, air conditioner or cooler is limited to a small area immediately in front of the air outlet. Attaching ducting allows the cold air to be directed to specific ‘hot spots’ to provide localised cooling, or diffused over a wide area to reduce temperature gradients.

Reduce air velocity - reduced air speed stops cold drafts, and lowers noise levels.


air distribution from air conditioning ducts

Overhead air conditioning ducts

Activair air conditioning ducts are usually suspended overhead from steel wires. Rows of small holes in the sides of the ducts produce jets of cold air that mix with the warmer room air before falling to floor level. Leading to draft free air movement throughout the building and reduced temperatures.



Air conditioning ducts in very hot environments

In very hot environments, such as foundries, commercial laundries, bakeries, etc. the holes are moved to 4 and 8 o’clock. The jets of cold air are now directed downwards, displacing hot air which is forced up and away from floor level. By using numerous small jets the air velocity is kept low, ensuring the workforce do not complain of uncomfortable cold drafts.


Air conditioning ducting for spot cooling

air conditioning ducts

Sections of plain and perforated air conditioning ducting can be connected to portable air conditioning units to provide spot cooling. This is very popular where cooling a large area is uneconomic or unnecessary. Cold air is discharged precisely where needed, keeping energy costs low.



For more information on Activair air conditioning ducting

Activair air conditioning ducts have been successfully installed in factories, workshops, gymnasiums, etc. to provide efficient cold air distribution for more information see:
