Klargester Airflow AF1 to AF4 (1 to 6 properties)

Unlike the Bio Disc the airflow models have no moving parts; sewage is treated by an aerobic biological process. The AF1 to AF4 range are designed for 1 to 6 properties, small developments, offices, and commercial properties where less than 25 people reside.

  • The airflow treatment plant employs the well proven aerobic biological process
  • AF1 to AF4 3D imageBelow ground installation.
  • No mechanical or electrical components within the plant minimise potential operating problems
  • Quiet in operation
  • Low running costs
  • Hydraulic surge control
  • Discrete covers
  • Minimal Maintenance helps decrease running costs
  • Discharges into a water course or a designed infiltration system
  • Optional internal pump for when discharge cannot be by gravity
  • Low visual impact pedestrian duty cover helps decrease problems with location.
  • Casing construction to BS4994 (1987) in GRP (Glass Reinforced Plastic).
  • Manufactured under the quality procedures of BS ISO9001: 2000.
  • Owls Hall offer a full commissioning and after sales service involving planned maintenance visits. Please visit our servicing section for more information.
  • Separate sample chambers for accurate and convenient effluent sampling, as required by the relevant authorities.
  • The AirFlow should preferably be no closer than 7m from the nearest property, whilst the blower housing can be located anywhere within a 15m radius of the plant itself.
