OPERATIONS GUIDE-TOM DRVAIR 400 AFTERCOOLER
1. Unit is sized for 400dm @ max 200psi. Optimal performance will be achieved at operating pressures
above 90psi.
2. Connect unit to portable battery using either the alligator clip or ring terminal adaptors which are
supplied with the unit. Make sure polarity is correct to have DC fan move air through the heat
exchanger toward the fan motor. Route power cord up through the bottom of the compressor to
the battery being careful not to pinch or chafe wires.
3. The integral pressure switch will keep the fan from operating until the unit is pressurized.
4. The air inlet connection is at the top of the cooler (#1 on front diagram) and appropriately marked.
5. The outlet ball valve is located downstream from the water separator and filter (if equipped) and is
also marked (#6 on front diagram).
6. Close the air compressor isolation valve prior to starting. Start the compressor and allow the system
to stabilize before gradually opening the compressor service valve to fill the DryAIR system.
7. Slightly open the manual drain on both the separator and filter to allow water to drain during
operation. Leave drains in this position during operation. Drain valve is marked with a green tag
.
8. Condensate can be captured in some type of collection tray, not provided in DryAIR package, or
piped away into a collection container depending on individual job site requirements.
9. The system depressurization valve, marked with a red tag, should remain closed during normal
operation. This valve is intended to be used to prevent free
z
e ups in cold temperatures or
otherwise drain the unit after use.

How It works:
TOM OryAIR aftercoolers are air to air heat exchangers that remove the heat of compression from portable air
compressor discharge air. In this process moisture Is condensed and collected in a cyclone separator to be drained
from the compressed air stream. If the unit is equipped with an optional coalescing filter, further polishing is
accomplished by trapping oil, in the form of aerosols, which are drained as well.
*Note: The filter element In the
coalescing filter rarely, If ever, wlll require replacement due to Its location In the system. The "service Indicator''
on the filter will alert you if necessary.
What it will NOT do:
TOM OryAIR aftercooler
s
in themselves will NOT produce breathing air
.
They are the first step in the process but
need additional components to assure breathing air quality and monitoring
.

representative.
