The VELODUCT® system is a complete system of round ducting
for which type approval for tightness class D according to EN
12237 has been granted.
All duct fittings are equipped with a sealing ring made of EPDM
rubber.
VELODUCT®
• permits rapid, easy and clean installation
• can be installed in any climate
• easy to balance
• reduces operating cost
• made of fireproof sheet steel
THE SEAL
The sealing principle is illustrated in the drawings below. These
show an insertion fitting and a fit-on (tube) fitting. The seal is
made of solid EPDM rubber and is fixed to the end of the fitting.
The seal is highly resistant to moisture, airborne pollutants and
solar radiation and can withstand continuous exposure to temperatures between -30°C and +80°C with an unimpaired function.

PRESSURE DROP CHARTS
Basic calculation data for ducts and duct components having
cross-section to Eurovent 2/3 and design to Eurovent 2/4.
The rated nominal air flow resistance (pnom) should be corrected
with regard to leakage and fan connection.
ΣΔptot = Δpnom + Δpleakage + Δpfan conn.
The air flow resistances are charted directly in Pa.
• The data in the charts refer to total pressure drop and are
therefore direct measurements of the energy loss across the
air flow resistances. (Pa = 1 J/m3)
• The influence of the choice of velocity on the pressure drop
can be judged directly.
• The difference in pressure drop between the first and the nth
branch can be read directly.
• The effect of a transition in 1, 2 or 3 size steps can be read
directly.

THE TYPE APPROVAL
T he Veloduct ducting system has been granted type approval by
SITAC (the Swedish Institute for Technical Approval in Construction) in accordance with Type Approval Certificate 1718/88. The
type approval signifies that a Veloduct ducting system, installed
in accordance with this instruction, complies with the provisions
of the Swedish Law (1994:847) on technical specification requirements for construction work, etc. In order for the type approval
to be valid, it is required that all details be marked as shown in
Fig. 1 or in a similar manner.
Fläkt Woods
3374 GB 2017.05.10
Components without this seal of approval may only be employed
to a limited extent and only if they are essential for connection to
items of equipment or for special matching of the ducting to the
building structure.
The supervisor must check any components which do not bear
the seal of approval with regard to the sealing employed and the
installation.the sealing employed and the installation.

INSTALLATION OF ROUND TUBES AND FITTINGS (TO TIGHTNESS CLASS D)
PREPARATORY WORK PRIOR TO INSTALLATION
WARNING!
Ventilation ducts made of thin sheet metal sometimes have razor-sharp edges.
3.Cut the tubes at right angles to the measured lengths (make
allowance for the fitting lengths of the components), and deburr the tube ends thoroughly, using a file or a deburring tool.
WEAR PROTECTIVE GLOVES!
Be especially careful with the following:
– cut edges of spiral ducts
– straight (non-folded) sheet metal edges of assembly parts.
1.Select a suitable section of ducting and check that the duct can
be run in accordance with the drawing before collecting the
necessary components from the storage area.
Fig. 4
Fig. 2
2. Collect the necessary fittings and tubes. Check that they aren’t
damaged in any way that would cause air leakage in the finished ducting system, such as holes left after rivets/screws
have been removed from reused parts. If the storage area is
well arranged and has good weather protection, the components will be easier to find, and the risk of damage or wastage
will be reduced. A sign such as that shown in Fig. 3 will facilitate the delivery of materials.

6.Lock the joints. All joints must be secured by means of
self-tapping screws or pop rivets in the ducts. The purchaser
decides which fasteners can be utilised for ease of cleaning.
The number of self-tapping screws or pop rivets necessary
is specified in the table above. Locate the screws at such a
distance from the tube end that the rubber seal will not be
damaged. Space the screws equally around the periphery, and
arrange them in such a manner that the gap between the tube
and the fitting will be as small as possible. The ductwork can
be locked with the tubes and fittings resting on the floor, or
this can be done after the ducting has been suspended. The
latter procedure facilitates adjustment of the overall length and
the positions of various fittings.

10.Readjustment of Veloduct joints: If it becomes necessary to
turn one or both duct components at their joint, and the rivets
or screws securing it are removed, the rivet/screw holes left
in the duct component will have to be sealed before the joint
is relocked. Keep in mind that an open hole in the insertion
end of the duct component will leak even though it is concealed by a tube or connection piece.

If sealing compound cannot be applied to the outside of the
branch (e.g. in the case of a mounting frame), apply ad­ditional
sealing compound at the inner end of the branch (3).
If the branch is accessible from the outside (item of equipment), spread out the compound which has been squeezed
out (4). If necessary, apply additional compound until a uniform, sealing bead has been

APPROVAL
12.Products without seal of approval incorporated into the ducting and fitted in accordance with the pro­visions of the seal
of approval must be sealed so that they will definitely be in
conformance with tightness class D. The seal at joints, etc.
must be checked visually before fitting into the ducting. A test
report must be produced for products with concealed joint
seals. Components not provided with VELODUCT seals must
be sealed in accordance with relevant parts of the example
below. The sealing material should be non-ageing and permanently elastic.

A flanged joint (bolted joint) must be fitted with a nonageing sealing strip and external corners under the flange
should be carefully sealed with sealing compound (3).
