INDICATIONS FOR USE STATEMENT – DENTAL DELIVERY SYSTEMS
The ASI Advanced Series is a self-contained dental treatment unit. It is designed to provide air, water, vacuum
and electricity to operate various dental handpieces, accessories and attachments and to serve as a base for
other dental devices and accessories.
The device is intended for use to provide general dental restorative care and hygiene procedures in both
traditional dental office settings and/or mobile applications by or under the supervision of a licensed dentist or a
hygienist if permitted by applicable law.
PRODUCT DESCRIPTION
The Dental System product is a cart-based operative dental treatment unit requiring connection to an AC
electrical power supply. The product is constructed of aluminum chassis with powder coat paint finish, high-
grade dual wheel type casters, and composite work surface top. The product is hard wired with the appropriate
type mains plug provided for the electrical specification model as listed.
The system functions to operate dental handpieces and to serve as an integrated base for other dental devices
and accessories. Use of the system is intended only to support dental treatment and hygiene procedures, and
operation of dental instruments by or under the supervision of a licensed dentist. All model configurations
include up to three handpiece connections, air/water syringe, air-only syringe and water supply with two 1-liter
bottles. The system does not include dental handpieces which are to be separately supplied by the operator.
MODELS AVAILABLE
See Model Specification Sheet for available models and features provided. Model Package Configurations may
include select models that are combined with handpieces and instruments.
THEORY OF OPERATION
The Dental Delivery System is a fully self-contained dental delivery unit that only requires a standard electrical
outlet for operation. The Advanced Delivery System is a pneumatically-controlled system that uses standard
compressed air for operation of dental tools and accessories and for pressurizing a closed water supply. The
system uses air pressure from a foot control to operate air driven tools and also to provide a signal to turn
electric instruments on and off. This pneumatic control capability provides flexibility in that additional
instruments can be included on the system for operation from the same foot control. The water system provides
two liters of clean water capacity that is used for handpiece coolant spray and irrigation for the air/water
syringe.

ties 3 – HANDPIECE CONTROL & OPERATION
www.asisupport.com Page 1 65-0049 Rev-A, (11/12/20)
HANDPIECE CONTROL AND OPERATION
The system utilizes common dental industry type technology for selection and activation of air-driven drills and
instruments via a multi-position control block. The block contains individual gasket diaphragms that are held in
the closed position by compressed air supplied by the handpiece holders. When a dental handpiece is removed
from its holder, the compressed air is relieved off the gasket diaphragms for that particular instrument thereby
allowing compressed air and water to flow to the handpiece when the foot control is depressed. The flow rate of
this compressed air is controlled by individual stems on the top of the block and the flow of water by individual
needle valves with knobs located on the front and side of the unit.
Electric instruments, such as the ultrasonic handpiece and electric motor, are controlled via the same control
block. However, the compressed air that flows from the block is routed to an air/electric switch that uses an air-
driven piston to close contacts when activated to thereby send an electric signal for the ultrasonic and electric
motor to operate. When the foot control is released, these instruments will then turn off.
The system uses an air-driven poppet style foot-control valve that when depressed, will send compressed air to
the control block to operate whichever handpiece is removed from its holder. The foot control also features a
toggle valve for selecting water to spray from the handpieces. When the toggle is activated and the foot control
is depressed, it will allow an air signal to travel through the foot-control tubing to open a water relay valve
allowing water to flow to the selected handpiece. When the foot control is released, it will exhaust off the air to
the water relay valve and allow it to shut.

TANDEM WATER DISINFECTION SYSTEM
The system features a tandem supply of two 1-liter bottles providing two liters of water for patient procedures.
This system includes a DentaPure water line cartridge that disinfects and treats the dental unit water to prevent
the formation of biofilm in the dental tubing. The tandem supply increases the volume of water available but
also saves costs by only requiring the use of one water line cartridge. The system works by allowing water in the
second bottle to flow into the first where it then flows through the disinfection cartridge. The water system uses
two 1-liter plastic bottles designed for holding pressure. The bottles can be filled with clean tap or distilled water
for the source of water supply to the dental handpieces and air/water syringe. The system works by supplying
regulated compressed air which pressurizes the water within the bottle and forces it up through the pick-up
tubing in the bottle.

COMPRESSED AIR SYSTEM
www.asisupport.com Page 1 65-0051 Rev-A (11/12/20)
The ASI Compressed Air System is designed to deliver oil-free air to run handpieces. This system is ideal for
mobile dental systems due to the small footprint, oil-less design, quiet sound level, and airflow output that it
provides.
AIR COMPRESSOR
A motor drives a two-stage piston design. Air is drawn into the first piston chamber where it is initially
compressed and then sent into the second piston chamber where it is compressed further. A pressure switch
controls the operation of the compressor that turns it on and off.
Due to the oil-less design, the compressor requires no lubrication and no maintenance.
The pistons are dynamically balanced to high tolerances that enable a smooth running and quiet design.
The portable dental air compressor is controlled by an air pressure switch that senses when the pressure drops
in the air tank to activate the motor and then once air consumption ceases, it will sense when the air pressure
has reached a pre-set point and then will turn off the motor. This keeps the motor from running when the
system is not in use.
The air compressor is mounted on special spring type isolators that allow it to float and thereby reduce vibration
to the chassis. A proprietary multi-stage intake muffler design attenuates and muffles sound waves to dampen
sound.
AIR TANKS CLEAN REGULATED AIR
This system uses a dual air tank design. The tanks are constructed of non-corroding aluminum that are
lightweight. Compressed air is sent to an in-line air regulator and moisture separator. The regulator is connected
to a manual purge valve that can be opened to allow moisture condensation to escape.

SUCTION SYSTEM
www.asisupport.com Page 1 65-0052 Rev-A (11/12/20)
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.
