DID YOU KNOW ?

Fan doors made of HDPE = NO hydraulics!

Poly works on air pressure, unlike heavy steel fan doors that need hydraulics to open/close.

PolyDuct Fittings

Polyline Industries have developed and manufactured an advanced range of moulded polyethylene products manufactured from linear Medium-Density Polyethylene (MDPE), a lighter material with better impact resistance than High-Density Polyethylene (HDPE).

STANDARD features of HDPE


  • Inert – Will not corrode
  • Flexible
  • Inbuilt noise absorption
  • Durable & impact resistant
  • Lightweight
  • Low maintenance
  • Low friction coefficient (0.02)

ADVANCED features of the moulded MDPE products


    A more robust moulded cylinder which is:

    • Seamless  – products therefore have less welds
    • Inherently round  – Rather than fabricated & inherently flat
    • Double Rings – Ensures vent bags will not blow off that even under the highest pressure
    • UV Stable for outdoor storage
    • Fire Retardants & Anti-Static additives available
    • Compatible Joining System
