BEFORE INITIAL START-UP ENSURE THAT THE COMPRESSOR OIL CHAMBER IS FILLED TO THE
CORRECT LEVEL WITH AIR SYSTEMS APPROVED OIL.
O
VERVIEW
The TA-3 is a portable, 3-man breathing air compressor designed exclusively for use with pressure demand
respirators. This system operates on standard 115 volt/60hz/20 amp electrical service. The system produces
pressure up to 110psi (7.5 bar) that is monitored by a built in pressure gauge.
Note: The TA-3 must have a Grade-D
filtration unit attached to the compressor to make a complete breathing air package.
Any 30 or 60 minute air
cylinder can be slid into the TA-3 frame and with the addition of a pressure reducing regulator and an Auto-Air
Breather Box™, you now have a 3-man compressor with full automatic backup air for IDLH operation (Model COMP-
3EA). The compressor should be connected to the filtration unit with a
minimum
0.5 inch I.D. breathing air hose.
CONSTANT FLOW RESPIRATORS CANNOT BE USED WITH THIS SYSTEM!
Note: Always run, store, or ship the compressor in the horizontal position.
Never stand the unit upright as
oil will drain from the sump and cause damage to the compressor. Check compressor oil level before each usage.
A 7/8" wrench is required to loosen the nut on the oil sump. Oil should be level with the bottom of the internal
threads.
DO NOT OVERFILL
. If oil level is low, add only Air Systems' approved oil. Order part number HP-268
USDA synthetic lubricant.

Warning: Always locate compressor in a fresh air environment away from toxic dusts, vapors, and fumes.
STEP 2)
Plug compressor into a 115 volt
receptacle with a dedicated 20 amp
service.
Note: If an extension
cord is going to be used, the cord
must be rated for a minimum 20
amp service (12/3 gauge).
STEP 1)
Compressor must be attached to a Grade-
D filtration unit. A minimum 1/2” I.D. hose
is to be used between the compressor and
the Grade-D filtration unit.
STEP 4)
Attach respirator supply hose to outlet fittings
on Grade-D filtration unit. Never leave an open
(unused) respirator attached to the system as
output pressure will not be maintained.
STEP 3)
Turn on the compressor and note the gauge
pressure reading on the compressor. Al-
low twin receiver tanks to fill to system
pressure 110psi (7.5 bar) output.
STEP 5)
Adjust the regulator on the Grade-D filtration unit to the required
output pressure (psi) of the pressure demand respirator. Review
manual on the Grade-D filtration unit and carbon monoxide monitor
for details on operation, service, and calibration before commencing
work. Attach and don respirator.
Note: Do not replace the coupling supplied on the compres-
sor tank outlet except with a checked style coupling of at least 1/2”
I.D. Do not use a Chicago style coupling on this type of compres-
sor.
