responsibility to ensure that such regulations are 
satisfied. 
All installation, assembly, commissioning and

PLEASE READ 

this  document  prior  to          

installation to familiarise yourself  with  the     
components and tools you require at the   

various stages. 

 
The primary reason for installing an air curtain is 

to prevent the influx of cold outside air through a 
door  opening  into  a  heated  area.  Typical       
applications include large despatch bay doors in 
factories and warehouses, and internal doors 
between areas of different temperatures. Wider 
door openings can be accommodated by bolting 
two or more units together. 
Air curtains control the internal climate by 

 

 

 

 

 

emitting an air stream with enough velocity to 
meet the floor so creating an air barrier in the 
door area. To prevent the ingress of outside 
draughts, the discharge louvre is angled 

 

 

 

 

 

 

 

outwards, so that the air leaving the building 
meets the wind trying to enter, thus deflecting it. 
(See diagrams below). 
Airbloc    air  curtains  provide  uniform  air          
distribution across the full width of the door, 
keeping heated or conditioned air inside the 
building and stopping the ingress of cold air, 
draughts,  and dust. 
This manual provides detailed information on 
the  installation  of  Airbloc  AB  electric  air         
curtains. It is essential that these products are 
installed 

in 

accordance 

with 

these                

manufacturers  instructions.
