  • Allows aerobic bacteria to colonise and further digest the pollutants to maximize settlement tank or septic tank efficiency.
  • Provides well over 1/2 mile of filtration media with over 5227 cu. cms. of open area to eliminate clogging.
  • 14,290 sq. cms. of filtering surface allow a flow rate of over  4500 Litres, filtering to 1.59mm. diameter.
  • Filtering surface is achieved with unique triangular bristles that more than double the filtering surface, with no uniform holes or slots to plug.
  • 90 degree handle for easy installation and removal.
  • Adapts to all types of 110mm. pipe.
  • Self-locking bristles hold the filter firmly in place, eliminitating "filter float up".
  • Flexible design makes it easy to install in hard to reach places and makes replacing the filter easy..
