AIRFLEX Blue – FLEXIBLE DUCTS FOR AIR VENTILATION SYSTEMS
Mechanical strength (PN-EN 61386-24): 450N
Impact resistance (PN-EN 61386-24): Normal (N)
Bending resistance: pliable
Reaction to fire class: D-s2,d2 (PN-EN 13501-1:2019-02)
Exterior layer:
Material: polyethylene mod. (HDPE-mod.)
Color: blue
Interior layer:
Material: polyethylene mod. (LDPE-mod.), antistatic
Color: white
Application:
Airflex Blue pipes have been designed for the purposes of “recovery” systems in single-family home construction. Recommended wherever anti-bacterial protection is not required.
Pipes have a smooth, anti-static interior coat which significantly limits settling and accumulation of dust in pipes and makes it possible to achieve high air flows at low pressure losses, contributing to the low energy consumption of the entire system. Moreover, it facilitates pipe cleaning if the need arises.
