OVERVIEW
SET-UP/OPERATION
MODEL: TA-3
The TA-3 is a portable 3 man breathing air compressor designed for use with pressure demand respirators when
used with a Grade-D ltration 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 ltration package with a minimum 1/2” I.D. breathing air hose.
Constant ow 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 overll!

STEP 1)
Connect compressor to the Grade-D ltration unit using a 1/2” I.D. hose.
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 ltration 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 ltration unit to the required output pressure of the pressure demand respirator(s).
Review manual on the Grade-D ltration unit and carbon monoxide monitor for details on operation, service, and calibra-
tion before commencing work.
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).

SET-UP/OPERATION
MODEL: TA-3EA
STEP 1)
Connect compressor to the primary air inlet on the Grade-D ltration unit using a 1/2” I.D. hose.
STEP 5)
Turn compressor on and note the gauge pressure. Pressure should reach 110 PSI (7.5 BAR).
STEP 6)
Attach hose(s) and respirator(s) to ltration 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 7)
Adjust the pressure regulator on the ltration unit to the required output pressure of the pressure demand respirator(s).
Review manual on the Grade-D ltration unit and carbon monoxide monitor for details on operation, service, and calibra-
tion before commencing work.
STEP 4)
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 2)
Connect back-up air regulator to back-up air inlet on the Grade D ltration unit using a 3/8” I.D. hose.
STEP 3)
Open back-up air cylinder valve and adjust pressure regulator to the required pressure of the respirator(s) being used.

FILLER PLUG (P/N COMPA040)
FILLER PLUG (P/N COMPA040)
WASHER (P/N COMPA043)
SIGHT GLASS
FILL PLUG (P/N COMPA042)
Blow dust off of oil cooler periodically to prevent over-heating.
STEP 1)
View pressure gauge to insure there is no pressure in compressor body.
STEP 2)
Remove ller plug/dipstick and gasket. (replace gasket if necessary)
STEP 3)
Position a suitable container underneath compressor and remove drain plug and gasket. (replace gasket if necessary)
STEP 4)
When oil is nished draining, reinstall the drain plug and gasket.
STEP 6)
Reinstall the ller plug/dipstick and gasket. Tighten to approximately 25Nm (18.5 ft./lbs.)
STEP 7)
Run compressor for approximately 10 seconds, turn off, recheck oil level, and add if necessary.
STEP 5)
Fill compressor with factory approved oil. Use Air Systems part no. HP-268 (approximately .8 liters). Oil should reach the
bottom threads of the ller plug/dipstick or just to the top of the sight glass. DO NOT OVERFILL!

REPLACEMENT OF AIR INTAKE FILTER
REPLACEMENT OF OIL SEPARATOR ELEMENT
STEP 1)
Remove the outlet tting from the compressor.
STEP 2)
Remove the black plastic cowl from the air end by pulling rmly.
STEP 3)
Remove the foam air lter and clean or replace. If lter is in good condition it can be cleaned with a mild detergent and
water.
STEP 4)
With lter removed, clean inside of plastic cowl and separator casing.
STEP 5)
There are 2 styles of air lters used on these compressors. A donut style lter that slides over the air end and is not held
in place by retaining clips (new style) and a strip lter that is held in place by retaining clips (old style). If you receive the
donut style lter and you have the retaining clips on your air end, simply cut the donut lter so it will wrap around the sep-
arator casing and the ends of the lter will be held in place by the retaining clips.
