Take-offs

Photo of product family: Take-offs

Take-offs are produced in diameters range 80 to 1600 mm of galvanized, aluminium and acid-resistant sheet.

They are recommended in the version with EPDM seals to ensure achieving "D" class leaktightness according to Eurovent (SITAC certificate). Depending on a type of connection, application and material there are following types of take-offs:

  • Connecting - ILS/ILSL enabling connection of round ducts to rectangular ducts. They are also produced in the pressed version ILPR/ILPRL with rounded flange to reduce resistance of flow. - Terminating pipelines with a steel mesh ILN and ASV which are produced with a drip directed at 45° angle protecting against precipitations.
  • Absorbing - ILA used to reduce vibrations of a system which occur as a result of operation of central units and fans. They are available as ILA-K version with steel flanges at both ends.

Round to rectangular pressed take-offs with gasket

ILPRL branches enable connecting spiral ducts or flexible ducts and square ducts. The bevel at the joint and the pressed structure provide an excellent air flow resistance. The wide hemming makes installation quick and easy. The safe-edge rim and the gasket provide a high air tightness class according to EN 12237.

Round to rectangular pressed take-offs

ILPR branches offer a perfect solution for fabricating ventilation ductwork joints at heat recuperation units in single- and multi-family houses. The bevel at the joint and the pressed structure provide an excellent air flow resistance. ILPR branches can be fitted with a gasket; ILPRL branches are provided with a factory-installed gasket on the flange.

ILPR-...-C pressed flat branches with radius have raw edges for fabrication of heat recuperation units, ducted air handling units, hot water coils, and other ventilation units.

Flat pressed straight take-off with gasket

 Flat straight branches are designed for connecting round
SPIRAL or plain ducts to the main square ducts. This piece
is also used for fabrication of expansion boxes in air supply
diffusers and wall-mounted and ceiling air diffusers. As a
result of the double EPDM rubber gasket, it is perfect for
both low- and high-pressure systems, since the product meets
requirements for air tightness class D according to EN12237.

Flat pressed galvanized sheet straight branches without gaskets
are used for fabrication of expansion boxes in air supply
diffusers, and wall-mounted and ceiling air diffusers. The sizes
63, 75 and 90 mm are prefabricated for FLX plenum boxes
installed with FLX-HDPE ducts in FLX-REKU air distribution
systems concealed beneath suspended ceiling panels or raised
floors. ILPF units are available with female-end flanges. The
flange can be fitted with a gasket; ILPL units are provided
with factory-installed EPDM gaskets on the flange.
ILP-...-C units have bare edges for fabrication of expansion
and diffuser boxes and other ventilation system components

diffusers, and wall-mounted and ceiling air diffusers. The sizes
63, 75 and 90 mm are prefabricated for FLX plenum boxes
installed with FLX-HDPE ducts in FLX-REKU air distribution
systems concealed beneath suspended ceiling panels or
raised floors. ILS branches can be expanded to match the
joined diameter, and there are ILSF branches provided with
factory-installed female ends. The branch can be fitted with
a gasket; ILSL branches are provided with factory-installed
EPDM gaskets on the branch.

Take-offs angle 45°

ILSV and ILSVL take-offs are male-ended fittings, and similarly
to ILSL units, they are designed for connecting round ducts
and square ducts. The difference from ILSL units is that the
take-off collar is inclined at 45 degrees for an improved air
flow rate and a reduced flow resistance. The take-offs can be
ordered with a different angle from 15 to 80 degrees.
ILSV-45 – angle take-off without a gasket
ILSVL-45 — angle take-off with an EPDM gasket,
air tightness class D acc. to EN 12237

Angle take-offs with mesh ASV-45

ASV / ASVL take-offs are male-ended fittings to be inserted
directly into round SPIRAL or plain ducts. The 12.7x12.7 mm
mesh installed right behind the duct end secures the exhaust
against birds, large insects, leaves or debris. The 45-degree
cut end forms a canopy against rain and snow, with an
added value of a neat finish. ASV-45 units are available with
female ends on request for connecting the take-off with a
ventilation bend.

ILSN / ILSNL take-offs are male-ended fittings to be inserted
directly into round SPIRAL or plain ducts. The 12.7x12.7 mm
mesh installed at the take-off end secures the air exhaust
against birds, large insects, leaves or debris. This is the
simplest form of ductwork termination with a minimum air
intake/exhaust flow resistance. ILSN units are available with a
female end on request for connection with a ventilation bend.

Flexible duct connector for circular ducts without flanges

Flexible ducting connector with male ends for joining two spiral or plain round ducts. Most commonly used for reducing vibration caused by ventilation and heat recovery units
as well as duct fans. Flexible ducting connector eliminates the transmission of vibration to the ducting system- consequently improving the acoustic performance of the installation.
It is made of AMT flexible duct connector (a joint consisting of a layer of fabric and two strips of sheet metal on both sides), which is available in different dimensions and materials also with increased temperature resistance.

Types of flexible ducting connector

  • flexible duct connectors with flanges - ILA-FLS - often used for joining with industrial duct fans.
  • flexible duct connectors with EPDM seals and male ends - ILA-NSL 
  • rectangular duct connectors - QILA

Flexible duct connector for circular ducts with male ends and seals

Flexible anti-vibration duct connector is used for joining two spiral or plain round ducts. It has male ends and is equipped with a seal. The flexible part is made of AMT flexible duct connector - a joint consisting of a fibreglass cloth, coated with of PVC, polyurethane, neoprene or silicone coating and two strips of sheet metal on both sides. The flexible connector effectively suppresses the vibration in the ductwork and ensures very good airtightness. There are also available flexible duct connectors with increased temperature resistance.

Circular straight sleeve with clamps

ILA-TK is a flexible duct connector used for neutralizing vibrations in circular ventilation ducts caused by air handling units, fans and other HVAC equipment.ILA-TK is a set of flexible fabric sleeve width 145 mm welded to the chosen diameter, and two clamps suitable to the size of the duct.

The clamps are made of stainless steel fastening bands and TKS-A locking devise with a screw made of carbon steel. Apart from the anti-vibration properties, the flexible connector is highly adjustable - ILA-TKA can be slid over nonstandard duct diameters – e.g. 95 - 102 mm – useful when joining with other materials rather than standard metal spiral duct.
