Square Duct Flanges
Makro Teknik’s flanges are produced for maximum
robustness, tightness and easiness of assembling at air ducts
applications. Galvanised steel in line with TSE 820 standart
is used at production. Non liquid, not frozen butyl mastic
for tightness, is injected to suture where duct is placed.
At design of 20-25 mm flanges additional measures are taken
to seal. At flange diagram, it is shown connection types, air duct
and flanges assembling methods at diagram according to
DW 144 – EN 1507 standarts.
