We are able to produce our products: - out of many different materials, e.g. aluminium, anticorrosive steel, black plate, etc. - different plate thickness (0,5-2 mm) - waterproof (soldered joints, polymer or silicon sealant) - with surface treatment (convetional and powder varnishing, galvanization, metallization)
Note: This table refers to each side individually, if stiffeners are found on both sides. The amount of stiffeners adds. Stiffeners are placed against each other diagonaly. Example: RU 2000x1500/2000 2+1=3 stiffeners are palce diagonally.
* Longer side is taken into account when considering transition parts. ** Inner radius is beveled at an 45° angle - see scheme of chosen component. This practise is used when R<300mm.

Connecting with Flanges
Flange consists of profiled Flange slats (PP20, PP30) and corners (R20, R30). Flanges are connected to ducts by point welds in corners and by clinch joints on along the Flange (maximum spacing 100mm). Point welds are coloured. Sealant is used in corners of Flange.
Flange slat is profile made of galvanized steel of thickness 0,8mm. Flanges are produces in lengths from 50mm up to 5000mm.
Flange corner is pressed part made of galvanized steel with zink surface layer. Corner is supplied with hole for connection screw and mounting holes for better fitting and easier assembly.
G-clamp is being used to connect 2 ducts with Flanges, when one side is longer 800mm. G-clamp increases tightness of ductwork.
S20 S30
R30 R20
Galvanized rectangular duct is standardly connected by Flanges, which consists of slats connected by corners. Ducts are transported with not attached Flanges in case of duct length adjustment and are connected by screws. Sealing duct tape is used between Flanges when assembling. G-clamps and C-slats are used with longer sides. Standard construction of HVAC ductwork is comparable with PK 120036 norm, class of tightness B. Always state joint type at the end of ordering code, if it is different than standard joint type. Standard construction: firmly attached profile Flange (P20, P30 - according to dimensions, see Profile Flanges. There is a possibility to use atypical iron flat or L-profiled Flanges.

Projection
Right-angled projection - basic method
8
Correct production of complex duct types depends on the right drawing of its projection. Right-angled projection is mostly used in practice. These rules are the most important when creating drawings: - projected point appears to be a point with the same distance from according base (line) - edge right-angled to projection plane appears as a point - parallel edge with projection plane appears as a line segment of the same size - slant line appears as a cosine element - right-angled plane appears as a line segment of the same size - parallel plane with projection plane appears as a real plane The most important views are: - front view (elevation - No.1) and side view (No.2), other views are useless, use them only if the situation requires them - top view (No.3), which is possible to use without using other views in some cases, while it is necessary to state,which dimension is closer to observer - combination of ther views, just in case if other views are not sufficient

Rectangular Duct Reducer is standardly strengthen by plate breaking. Standard length of Rectangular Duct Reducer is 300mm or 500mm, we are able to produce other lengths (50-2000 mm). It is important to correctly state the right values or enclose drawing. Shorter form: PRO both sides axial, PRN one side right-angled and second dimension does not change. PROA, PROB at least one side is axial and the other right-angled. A or B depends on which side has common axis.
PR, dimensions AxB=800x400mm, A1xB1=630x315mm, length L=500mm, one side right-angled, second side does not reduce.
Standard length is 300mm or 500mm, we are able to produce other lengths (50-2000 mm). It is connected by spot welds lenghtwise(up to length 800mm), pressed when longer. Correctly state the right values or enclose drawing. Short forms similar to Transition. Extension length: P=50mm (d80-d900), P=75mm (d1000-1600)
PR, AxB = 800x400mm, A1xB1 = 630x315mm, length L=500mm, both sides according to drawing above (state offset values).
PR, AxB=800x400mm, A1xB1=630x315mm, length L=500mm,side B/B1 is right-angled, side A/A1 axial (we use PROA, when side A/A1 is axial, do not state offset Ub, because side B/B1 is right-angled, so that straight Ub=0 - we state it, just when
Ub≠0).
Square to Round Transition, dimensions AxB=400x250mm, d=200mm, L=300mm, both sides axial (use marking PRKO).
Square to Round Transition, AxB=400x250mm, d=200mm, L=300mm, both sides offsets (state value).
Square to Round AxB=400x250mm, d=200mm, L=300mm, side A/d right-angled, side B/d in axis (when side B/d is axial, use marking PRKOB, offset Ua do not state, because side A/d is right-angled, so it equals zero - state it,
if it does not equal zero).

The Silencer serves to reduce the noise emitted by the duct pipes. Standard Silencer baffles can be fitted by haunch or turning vane, which reduces aerodynamic baffle drag and thus reduces the pressure loss of the Silencer. Silencer baffle is designed for placement into a horizontal pipe. Baffle consists of profiled galvanized steel frame and filling of sound absorbing mineral wool. Mineral wool is placed into the covering fabric (NGR), which is hygienic and repels moisture. In the case of designs with a haunch or turning vane, these plates are included in the total length of baffles. Possible usage of turning vane: When ordering a Silencer without a guide plate it is not necessary to state marking into the ordering code. Silencer Duct consists of Duct and individual baffles depending on the width and the distance of free space between inesrtions, frequency and total length of the Silencer Duct. maximum operating temperature : -40 / +100°C maximum flow velocity : 20 ms (It is possible to state joint type when ordering, see Transition)

The outer shell of Silencer Duct (THP) is Rectangular Duct from galvanized steel with flanges at the ends of both sides. Silencer Baffle (TH) consists of galvanized steel frame and filling of mineral wool, which is protected by a covering fabric. Attachment of the Silencer Baffles is provided by screws 4.2 x 13 mm placed 50 mm from the flanges and in the middle of Duct lenght. Amount and type of baffles is determined by the project engineer in the HVAC implementing project. Flanges are included. General method of spacing is shown in the picture. Another way for the placement of baffles into the pipe is not recommended. TH20 Baffle has a width of 200 mm and TH10 has a width of 100 mm. Dimensions of the Silencer Duct, type and amount of Baffles will be determined by the designer as required for noise reduction. Silencers (THP) are not supplied assembled for better handling when shipping and mounting. TH assembly is carried out by conventional methods for installing HVAC Duct.

Flexible Duct Connector, A=630, B=315, standard length L=130mm
Flexible Duct Connector is used to prevent the spread of vibrations and noise in Duct by inserting between source of the spread and Duct. Flexible Duct Connector consists of rubberised textile fabric, which is ended on both sides with galvanized sheet and two Flanges. Wide range of designs and sizes of Flexible Duct Connector with unique hem ensures an airtight and watertight connection of HVAC Duct that can be used in any operating conditions. Standard version (up to a temperature of 80° C) is made of galvanized sheet steel and polyester/PVC. Flexible Duct Connector made of these semifinished products withstood the pressure of 200 kPa at the pressure measurements test. Standard length of the PVC part is 130 mm.
Level of filtration depends on used filtration material. G3 level of filtration is standardly used. We determine sliding direction of insertion by correct order notation. Side A is depth of cassette insertion. Sibe B contains seizable part for disconnection (see photo and scheme). It is necessary to remember free space for disconnection of cassette insertion, because it is essential to change filtration fabric. Standard length of Filtration Cassette is 150mm.
