STREAM Gravity Vacuum System is suitable for integration with traditional rubbish chutes found in residential and commercial tower projects in Australia.

Users throw their waste through the normal indoor chutes (traditionally found in Australian high-rise buildings). The waste is dropped and stored in a storage section, at the base of the tower, which is designed to temporary hold the waste between transport cycles. When the waste reaches a certain level or due to preset timer, the exhauster fan starts to create airflow from the primary air inlet and into the pipe network. The Discharge Valve door opens automatically to unload waste from the temporary storage section into the pipe network to be transported to a sealed container located at the central waste handling facilities. The container is then collected and emptied at specific times by a flatbed hook-lift truck for final disposal.

This system is specifically suitable for residential developments. 

STREAM Gravity Vacuum System is integrated with safety mechanism. It is safe and suitable for all users including children.

Gravity Vacuum Station Operation​

  1. Refuse will be thrown into the chute via Volumetric Control Hopper Door

  2. When the refuse reach to the pre-set level, STREAM Control Centre (SCC) will trigger the Centrifugal Fan (CF) to create the vacuum and airflow inside the piping system. 

  3. The Discharge Valve (DV) will be opened to discharge the refuse to piping network.  Primary Air Intake (PAI) will be opened to allow the air  

  4. The refuse will be transported via the piping network to Bin Center in the speed of 20 – 25 m/s.  

  5. In the Bin Center, the refuse and air will be separated in the Waste Container or Waste Separator.

  6. The air will be filtered, DEODORIZED and discharged.
