SRF material recovery tests at Impact Air Systems’ test facility

Impact recognises the pressure on the industry to provide a high-quality waste stream, so has enhanced a successful separation solution which greatly improves the separation of valuable recyclable materials while providing the operator with a highly durable, low maintenance and hassle-free system.

Combining our highly skilled in-house engineering team, 3D modelling software and working in conjunction with our carefully selected external supplier base, the ZAC800 boasts impressive resistance to abrasive materials, less moving parts and the very latest filtration technology, whilst maintaining its exceptional separation efficiency.

Utilising density separation by the power of air, the ZAC800 is specially engineered for processing of glass rich or highly abrasive sub 100mm material streams, constructed from carefully selected materials ensuring exceptional durability. The Zigzag cascade enclosure includes hardened chromium cast plates to greatly reduce wear from glass.

Impact has carried out numerous successful tests on SRF material to increase purity rates for the clean SRF product depend on the residue infeed material. If there are long parts present, a long part separator (LPS) can be added to reduce obstructions and improve separation. The long parts – wood, plastics, wire, etc are rejected and the glass and fibre fraction are processed in the ZAC800 unit which separates the glass and fibre/plastic film into two separate discharge conveyors.

As a final quality control, a head drum magnet can also be added to the glass discharge conveyor to remove any ferrous metals that have not been recovered already.

The ZAC800 SRF Recovery/Clean-up System

  • Input material; MRF residue = glass, fibre, plastics, wood etc.
  • Capacity; 10 to 15 tph depending on bulk density and input material size
  • Input material size; 0 to 80 mm approx.
  • SRF purity; > 90% depending on input material composition


  • Short term ROI (from 5 to 12 months depending on operational shift pattern and initial ZAC800 options)
  • Higher income for quality SRF fraction
  • Savings on landfill diversion, transportation and handling costs
  • Low operational and maintenance costs
  • Fully flexible – can be incorporated into existing sorting systems/MRF’s or as a standalone process
