AIR SYSTEMS TA-3 Operating Manual page 2

The TA-3 is a portable 3 man breathing air compressor designed for use with pressure demand respirators when
used with a Grade-D filtration package. The system operates on 115 VAC / 60 Hz / 20 amp electrical service. The system
produces pressure up to 110 PSI (7.5 BAR) that is monitored by a built in pressure gauge. Adding a 30 or 60 minute air
cylinder, pressure reducing regulator, and an Auto Air Breather Box™ gives you a 3 man compressor with automatic back-
up air for IDLH operation.
notes: The compressor should be connected to the filtration package with a minimum 1/2" I.D. breathing air hose.
Constant flow respirators cannot be used with this compressor system!
Always run, store, or ship the compressor in the horizontal position. Never stand the compressor upright as oil will
drain from the sump and cause damage to the compressor.
Check compressor oil level before each usage. If oil is low, add only Air Systems approved oil. Order P/N HP-268
USDA synthetic lubricant. Do not overfill!
GRADE-D FILTRATION
1/2" I.D. BREATHING
AIR HOSE
SteP 1)
Connect compressor to the Grade-D filtration unit using a 1/2" I.D. hose.
SteP 2)
Plug compressor power cord into a 115 VAC receptacle with a dedicated 20 amp service.
Note: If an extension cord is to be used be rated for a minimum 20 amp service (12 AWG).
SteP 3)
Turn compressor on and note the gauge pressure. Pressure should reach 110 PSI (7.5 BAR).
SteP 4)
Attach hose(s) and respirator(s) to filtration unit. Up to 3 respirators can be used with this compressor. Never leave an
open (unused) respirator attached to the system as output pressure will not be maintained.
SteP 5)
Adjust the pressure regulator on the filtration unit to the required output pressure of the pressure demand respirator(s).
Review manual on the Grade-D filtration unit and carbon monoxide monitor for details on operation, service, and calibra-
tion before commencing work.
