Rectangular ducts

• Rectangular elbows with rounded outer back with Z-ribbed nail,

 snap lock or Pittsburgh flange

• the elbows are manufactured with angles of 15 to 135 degrees

 and F20 or F30

• the inner back can be manufactured with a radius Rm or straight

 section /standard Rm = 130mm/

• Rectangular elbows – reducers with rounded outer back of snap

 lock or Pittsburgh flange and Z ribbing

• the elbows are manufactured with angles of 15 to 135 degrees

 and F20 or F30 coonnecting profiles at both ends

• dimensions only on side a may be different.

 size B does not change

• Used for deviations of a system, for example when passing

 channels, beams, or the like

• There is a F20 or F30 profile at both ends, assembled on a Snap

 lock or Pittsburgh flange and it is Z ribbed

• There are specific requirements between size A, deviation Rm and

 length L

• Therefore is recommended to use standard lengths L and

 deviations S

 Application:

• Used to connect different sized channels

 in a ventilation system

• There is a F20 or F30 profile at both ends, assembled on a Snap

 lock or Pittsburgh flange and it is Z ribbed

Types of reducers:

• symmetric – pos. 1

• asymmetric - pos.4; 5

• double asymmetric - pos.2; 3; 6

• rotating

• Used to seal the end of the air duct system

• Mounts to the rectangular duct through bolts and nuts

• Join to the connection profile of the air duct via E23 clamps

• For two-sided deviations from the main duct

• For connecting two deviasions from the ventilation system to the

 main duct

• There is a F20 or F30 profile at both ends, assembled on a Snap

 lock or Pittsburgh flange and it is Z ribbed

• For two-sided deviations from the main duct

• For connecting two deviasions from the ventilation system to the

 main duct

• There is a F20 or F30 profile at both ends, assembled on a Snap

 lock or Pittsburgh flange and it is Z ribbed

• For two-sided deviations from the main duct

• For connecting two deviasions from the ventilation system to the

 main duct

• There is a F20 or F30 profile at both ends, assembled on a Snap

 lock or Pittsburgh flange and it is Z ribbed

• Serves as a starting or ending element in ventilation systems

• Prevents the ventilation system from entering water, animals, waste, etc. 

• There is a F20 or F30 profile at both ends, assembled on a Snap lock or Pittsburgh flange and it is Z ribbed  

• The standard angle is 45 degrees

• To reduce the noise and vibrations between the fan and the air ducts 

• High resistance to sun and moisture. Very good mechanical resistance 

• There is a European joining profile type A20 or A30

• Used as end elements in rectangular ventilation systems

• Protects the smoke flue from snow, rain, insects, birds and others

additional elements used to build ductwork systems of rectangular air ducts
