Construction
Deltavent sectional lengths/fitting components are fabricated in a variety of diameters and lengths with continuously welded vertical seams. The Deltavent system also utilises four insulated/non-insulated annular variation options to provide a required minimum external case surface temperature. Inner liner coupler characteristics consist of male and female connection sockets complete with a 10mm 90° right angled flange formed at either end of all components. Deltavent joints shall be secured by clamping an externally fitted V-Band over the mating flanges of the adjoining components.
Diameter RANGE
This double-lined system is available as Deltavent 25 (with a 25mm insulating gap) or Deltavent 50 (with 50mm mineral wool insulation). There are also 75mm and 100mm annuli available on request.
