Rectangular ducts

Product symbol:: Kanał L>=0.9 Kanał L<0.9[/et_pb_text][et_pb_text _builder_version="4.8.2" hover_enabled="0" sticky_enabled="0"]

  • Straight ducts ≥ 900 mm in length are regarded as STRAIGHT CONNECTION PIPES .
  • Straight ducts < 900 mm in length are regarded as FITTINGS.
  • We produce straight ducts in L sections=1500 mm.
  • If you order a rectangle with a length exceeding 1500 mm, it will be manufactured in sections of 1500 mm + the resulting rest.
  • There is a possibility to produce a duct longer than 1500mm.
  • The ducts are ended with “fixed” mounting frames.
  • It is possible to produce a loose frame : designation- “PSL”.

Tees

Product symbol: Trójnik R150, Trójnik R=0

  • They are ended with “fixed” mounting frames.
  • In round tees as standard:

radius: E, F = 100

straight connection pipes: G, H, K, L = 50mm

  • In straight tees as standard:

straight connection pipes: E, F, I, J = 50mm

Reducers

Product symbol: Red Prost

  • They are ended with “fixed” mounting frames.
  • They allow changing all dimensions and offset pipes in both directions.

A – inlet width
B – inlet height
C – outlet width
D – outlet height
F – horizontal left offset pipe
G – horizontal right offset pipe
H – vertical offset pipe:
“+” down
“-” up
L – length

Bends

Product symbol: Kol 90 R150, Kol 90 R=0, Kol 45 R150, Kol 45 R=0

  • They give the possibility to change the dimensions of the duct on sides A and C.

straight connection pipes D, E, F = 50mm

Note:

In bends with an angle < 45° or side A≤400mm, the air guide vanes are not required.  They are used for larger dimensions to reduce the pressure loss of the bend.

Diffusers

Product symbol: Red P-O

  • Change of cross-section from rectangular to round.
  • The rectangular section is ended by a “fixed” mounting frame.

A – width
B – height
C – diameter
D – horizontal left offset pipe
E – horizontal right offset pipe
F – vertical offset:
“+” down
„-”  up
L – length

Offset pipes

Product symbol: Skok 1, Skok 2

  • They are used to connect two rectangular elements with a change in height of the ventilation duct or to bypass an obstacle in the way of the ventilation duct.
  • They are ended with “fixed” mounting frames.
  • They give the possibility to change dimensions on sides A and C and offset E.

A – inlet height
B – width
C – outlet height
D – length
E – offset
F, G – straight connection pipe (30mm – standard)

End caps
