Arial loading systems PE-air lose with a
3- and 8mm - perforation
     
 

To pass the desired amount of air through the air hose (depending on the capacity of the ventilator) it can be perforated in different ways depending on how the customer wants to ventilate the locations.
     
   

 

System A (standard perforation)

• The air hose is perforated completely letting out the air on all sides.
   This system is used in refrigeration chambers since the air gets to
   all points of the room.

• When it is necessary to protect the workers from currents other
   types of perforation will be used.

 

 

    
     

 

System B (partial perforation)

• The air hose is perforated following the requirements of the customer
   only partially in some segments of the hose.

• This system is used to achieve an optimum refrigeration preventing at
   the same time to expose the workers to air currents, for example in a
   packaging hall.

• For technical reasons the perforation is only possible on both sides equally   (reflected).

 

  
           

System B / C (one-sided perforation)

• The air hose is perforated only on one side following the demands of the
   customer (see system A but only one-sidedly ).

• This system is used when more than one hoses are situated close to
   each other.

• It is also possible to perforate from “9 to 12 h” (compare system of the clock).
               

Possibilities of fixing the tubes

The air hoses can be fastened to one or two wires (or tracks) by snap links. Depending on the demands of the customer the tube will have one or two
rows of eyelets. The distance from eyelet to eyelet will be of 80 cm when
fastening on one wire and of 1,0 m when fastening on two wires. The two
wires have to go parallel to each other with a distance of 360 mm.
