Airsox: 

Steel Ducting: 

Air Distribution*

Uniform delivery, no dead zones

Dead zones will most likely occur

Cooling Capacity*

May often be reduced as most of the cooling
capacity is used in the occupied zone directly

Higher cooling capacity is often required as
the entire room is stirred

Installation costs*

Very low: It is possible to save app. up till 70%
installation time. This is mainly due to the large weight difference between ducting and airsox. Steel ducting is app. 20 times heavier. 

Very High. Heavy work load due to the weight of the steel ducts. It will also be much more time consuming due to the weight and handling problems on site.

Initial costs**

Normally lower than for steel ducting. Prices of yarn have been stable also through the economic crisis since 2008

This is typically higher also because of the raising steel prices.

Colours***

Euro Air can deliver a huge variety of colours to
satisfy the architectural demands.

This is very time consuming and also very expensive 

Air exchange rate*

High because the whole surface area of the
fabric system is used as one big diffuser.

Only in theory, as it could lead to draft problems in certain areas of a room.

Risk of draft in the occupied zone*

Risk is very low, also with high air exchange
rates

Here is a potential risk, depending on the air exchange rate for the room

Weight of section

Ø-500 x 1.000 mm

App. 550 g

App. 8.700 g

Maintenance

The textile system from EuroAir is easy to dismantle and hang up again after washing

Due to the complexity of cleaning a steel duct it is often postponed or often not done at all. This will have major effects on the indoor environment of the building its occupants

Noise suppressed

This is normally not taken into consideration

 Very seldom

Noise generation

Very low risk when using the Permeable
System from Euro Air

Often depending on the flow and type of diffuser
