Duct and fittings insulated with rubber mat

The ventilation and air conditioning ducts and fittings insulated
with rubber mat constitute the complete FOAM System
piping . It consists of round spiro pipes and ventilation fittings:
elbows, T-pipes, reducing pipes, joints and stub pipes. The
inner diameters comply with the standard round elements
according to the following tolerances. The insulation made
of rubber mat is available in 4 sizes: 9, 13, 19 and 25 mm.

FOAM System is based on the aforementioned tolerances
for ducts, so as to ensure the sufficient system tightness.
Diameters of elements made of sheet, in accordance with
PN-EN-1506:2001

Pressed ventilation elbows insulated with rubber mat,applied for installations running at places where their further insulation is impossible. They are perfectly fit for the duct airconditioning
system where the use of the 9-25 mm insulation is possible.

The elbows are available with standard 90- and 45- degree angles and in the short version as F..-BPKL-…-…, or in the short sleeve version as F..-BPKFL-…-…, which enters into the
spiro pipe on one side and overlaps the frame of e.g. KN-RMddd valve on the other side.

T-pipes for distribution of air in the ventilation system. The
most typical one has a branch-off with the same or similar
diameter in relation to the pipe opening. The 90-degree angle
is the most universal one - in the case that the non-standard
nature of the system requires the 45-, 60-, 15-degree branchoff,
it must be discussed and quoted separately.

The sleeve joins two fittings which are of the size of the nipples - it overlaps the fitting such as an elbow, a T-pipe or a reducer on both sides. It complements the system of  ventilation and air conditioning ducts and fittings.
