Your AIRSTAR generates 100% oil-less, ultra-dry dental air which protects valuable hand-
pieces from premature failure due to the effects of moist air and the build-up of oil residue.
Because no oil is used for mechanical lubrication, there is no chance of introducing an oily film
to a prepared surface which could compromise resin retention and restorations, wasting chair
time. Most important, your patients’s health is protected with ultra-dry air that provides an envi-
ronment that is not conducive to bacterial growth.
The AIRSTAR utilizes a long stroke, small bore piston to compress the air. This piston is bonded
with an anti-friction polymer to eliminate the need for oil. The air is forced through the Membrane
Dryer System consisting of the cooler and the membrane. This system removes moisture and
air impurities providing the driest possible compressed air while maximizing performance. This
100% ultra-dry air is reserved in the main storage tank for use by the operatory air system.
The AIRSTAR features include:
Maximum Dryness with Quadruple Filtered Air
Compact size for space-saving installation
Uninterrupted Compressor Availability
Virtually Maintenance Free
Low Pressure Dew Point
Since 1971, when Air Techniques pioneered the manufacture of oil-less air for dentistry,
thousands of dentists have depended on their AIRSTAR. Now that your practice has an
AIRSTAR , you, too, can depend on the delivery of 100% oil-less, ultra-dry air and efficient,
trouble-free operation.

INSTALLATION INFORMATION
Important: Each system should have a dedicated circuit panel.
Remove all power to the system prior to working
with electrical circuits. Contacting high voltage
can cause serious injury or even death.
All systems must be wired directly
from an electrical box that complies
with local electrical codes.
Note: If voltage is higher than 242V, install a bucking transformer.
MINIMUM VOLTAGE: The minimum voltage for an AS12INT, AS22INT, AS50INT or
AS70INT is 198 Volts. Install a boost transformer if the service is below this rating.
WIRING REQUIREMENTS: To help prevent re, electric shock, injury, or death, the
wiring and grounding must conform to the latest edition of the National Electrical Code,
ANSI/NFPA 70 and all applicable local regulations. Please contact a qualied electri-
cian to check your wiring and breakers/fuses to ensure that there is adequate electrical
power to operate the AIRSTAR.
EQUIPMENT GROUNDING: All AIRSTARs must be connected to a grounded metal,
permanent wiring system, or an equipment grounding conductor must be run with the
circuit conductors and connected to the equipment grounding lead in the AIRSTAR's
exible metal conduit power supply. Failure to do so can result in re, electric shock,
injury, or death. See Figure 2, Overall Site Requirements, page 7.
ELECTRICAL POWER CONNECTION: AS12INT is supplied with an installed line
cord with an IEC female connector that requires a 220V male IEC, minimum 16AWG,
connector. AS22INT, AS50INT and AS70INT systems are shipped with open electrical
connections, which are directly connected to the branch supply circuit as shown by
Figure 3. See Site Electrical Requirements, page 7, for required branch circuit size for
each system.
AIRSTARs are installed by authorized Air Techniques dealer technicians. Please review these
installation guidelines to make sure that your AIRSTAR works to capacity for your office. (See
Site Requirements, pages 6 & 7.)
Your AIRSTAR should be installed in a well ventilated area, with at least 12 inch
clearance on each side for service access and to prevent overheating during high
demand periods. If other equipment is located in the vicinity, the ambient temperature
of the area must not exceed 105°F.
The installation site should be clean and dry to prevent the air intake filters from
clogging. If there is a concern about the quality of air where the AIRSTAR is placed,
we recommend an optional Remote Air Intake (See Optional Accessories, page 16)
which allows the compressor to intake clean air from a remote location.
Air distribution piping for all models should be 1/2", type "L" or type "K" copper.
PLUMBING CONNECTION: The Tank Outlet Assembly (See Figure 1, View C), (the
storage tank outlet for the dry air) is connected to the operatory air system via a 3/8"
F.N.P.T. shut-off valve and 6 foot length of pressure hose (supplied).

After your AIRSTAR has been installed and before it is put into operation, be sure to follow
the check-out procedure detailed below:
Check that Intake Filter(s) are fully seated into the compressor head(s) and that the Tank
Outlet Valve is closed.
Turn on the electricity. Check the incoming line voltage. It should be at least 198 Volts
for the AS12INT, AS12CINT AS22INT, AS22CINT, AS50INT, AS50CINT and AS70INT.
This voltage should remain at or above this level while the AIRSTAR is running. If
not, install the appropriate boost transformer and check that the correct main circuit
breaker and wire size are being used.
Check pump-up and recovery times.
Turn on the AIRSTAR’s power and determine the pump-up time from 0 to 115 PSI.
Drain the storage tank to 80 PSI and determine the recovery time from 85 to 115 PSI.

Like all precision products, your AIRSTAR requires a certain amount of care on a regularly
scheduled basis. A well-organized maintenance program aids dependable equipment operation
and reduces problems to a minimum. Routine checks help to detect general overall wear, and
replacement of parts can often be made before a problem occurs.
Understanding this, we have established minimum maintenance requirements listed below
that include routine inspections and the replacement of filters using preventive maintenance
kits available for the specific AIRSTAR model. Adherence to this recommended maintenance
schedule will ensure that the equipment will continue performing at its best with uninterrupted
service.
Routine Inspection - Monthly
Clean exterior surfaces.
Check for abnormal noises and air leaks.
Make sure that no ammable, corrosive, or combustible materials are stored in
the equipment room (especially in the area around the equipment).
Check operational range of pressure switch is between 85-115 psi.
Inspect the Moisture Monitor (Figure 4) for a color change:
Blue indicates that the air in the storage tank is dry.
Pink indicates a high level of humidity is in the storage tank. See TROUBLESHOOTING
page 13 to correct this situation.
Routine Inspection - Yearly
Refer to Figure 4 and check the Service Indicator on the 5-micron Outlet Filter.

WARRANTY
Each AIRSTAR is warranted to be free from defects in material and workmanship from the date
of installation for a period of 2 years (24 months) on complete unit.
All part and component returns and replacement equipment require a Return Materials
Authorization (RMA). Returns must be received within three months of the RMA issue date
and in appropriate packaging to prevent shipping damage. In case of advanced replacement,
products shall be returned in the original packaging. Items returned without an RMA, or included
with other products for which an RMA has been issued, will be returned to the customer at the
discretion of Air Techniques, Inc.; the return shipping is the customer's responsibility.
Any item returned under warranty, will be repaired or replaced at our option at no charge
provided that our inspection conrms it to be defective. Air Techniques, Inc. is not liable for
indirect or consequential damages or loss of any nature in connection with this equipment.
Dealer labor, shipping and handling charges are not covered by this warranty.
Warranty credit will not be applied to product returns that exhibit damage due to shipping,
misuse, careless handling, and improper installation by dealers, or repairs by unauthorized
personnel. Credit, or partial credit, will not be issued until products/parts have been received
and assessed. If, after the evaluation it is determined that there is no-fault found and the
unit is working properly, a credit will not be issued. Warranty is void if product is installed
incorrectly or installed or serviced by anyone other than an authorized Air Techniques'
dealer or service personnel.
This warranty is in lieu of all other warranties expressed or implied. No representative or person
is authorized to assume for us any liability in connection with the sale of our equipment.
