HOW THE SYSTEM WORKS
When power is applied, fresh air is taken in through air filters and compressed by the pump pistons. The compressed
air is very warm and is cooled for use by the heat exchanger and fan. Air is then delivered to the coalescing filter to
remove most of the moisture.
The coalescing filter is equipped with an automatic draining feature that allows the draining of the excess moisture.
The cool air enters the desiccant-style dryer assembly to complete the moisture removal by removing 99.7% of the
water vapor from the air.
Air is directed into the dryer (desiccant) cartridges, from one to the other, by electronically controlled solenoid valves.
The timing for the solenoid valves is provided by the Aeras control.
While the air is moving through one cartridge, the desiccant in the other cartridge is being dried by air directed through
an orifice in the outlet shuttle valve. This valve cycle will be noticeable by a short burst of air from the purge valves. The
air is then collected in the tank where it is stored for future use.
The Aeras control panel LCD display shows the tank air pressure. When air is called for to run equipment in the facility,
it goes through a particulate filter to remove any remaining particulates from the air.
The tank pressure is monitored by the Aeras control, using a pressure transducer sensor on the manifold block, which
runs the motors on demand. Pressure is factory set from 85 PSI/586 kPa to 115 PSI/793 kPa.
GETTING STARTED
WARNING
Never direct the air stream toward any portion of the body or others in the vicinity. Pressurized air streams can be
extremely hazardous to your health and can result in death in certain circumstances.
CAUTION
DO NOT attempt to operate the compressor at ambient temperature below 35°F/2°C or above 100°F/38°C.
The Aeras compressor is easy to operate and maintain.
1.
Verify the compressor is connected to a dedicated circuit.
2. Verify the compressor is properly connected to the facility plumbing and a fresh air source.
3. Verify the shut-off valve is closed.
4. Put the antenna (located on the right side of the control panel) in the upright position.
5. Push the Aeras control panel power switch to the ON position.
6. To switch the compressor from STANDBY to ON, press the orange
STANDBY
switch on the
HOME
screen. The
switch will turn green and display ON.
7.
Test for leaks
(SECTION V - CARE - MAINTENANCE - TEST FOR AIR LEAKS)
8. Turn the shut-off valve to OPEN.
9. The compressor installation is complete.
NOTE:
Periodically during startup from 0 PSI, the dryer shuttle valve may be out of sync from the previous cycle. This
is noted by the sound of air being released out of the dryer purge valves. This minor interruption causes no harm to
the dryer or air system. The dryer shuttle valve will relocate itself to the correct position after 35 seconds, and after
which the dryer will cycle normally.
