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
