The ASI dental suction system is designed to provide suction to perform dental procedures and features a high-
volume suction and saliva ejector attached to a solid collector filter.
VACUUM PUMP
A motor drives a two-headed oil-less piston pump.
The pistons require no lubrication due to their oil-less design. The pistons are dynamically balanced to high
tolerances that enable a smooth running and quiet design.
SEDIMENT SEPARATOR AND HOLDING TANK
Equally important to the suction design of mobile dental equipment is how the liquid contents are handled. The
suction system has a holding tank to provide capacity for a normal day of procedures and is able to handle
caustic chemicals and can be purged and cleaned at the end of the day.
The system separates the air stream from the liquid and provides a sediment bowl that can be removed.
Built into the top of the holding tank is a float switch to prevent over filling of the canister. Once the liquid rises
to a pre-set level, the float switch will cut off the power to the vacuum pump.
PURGE SYSTEM
The system uses an electric purge pump that can be turned on that will siphon the liquid from the holding tank
and empty out though the purge hose at the back of the system. At the end of the day’s procedures, the purge
hose can be placed into a sink drain or quick connected to a sink’s P-trap and then the pump turned on to purge
the tank. Once complete, water with evacuation cleanser can be suctioned up through the high volume
evacuator (HVE) and saliva ejector to rinse the tubes and the holding tank.
The pump squeezes the specially designed tubing to pull and push contents through the tube. This pump design
allows it to pull granular or sticky paste-like materials.
