Introduction
The operation of the LPSA Air Dryer is based on the pressure swing adsorption (PSA) cycle
using a synthetic zeolite molecular sieve. The LPSA Air Dryer is capable of delivering dry air
flows up to 20 standard cubic feet per hour (SCFH) for LPSA20, and 60 SCFH for LPSA60 at
−
60
°
F to
−
90
°
F dewpoint at rated conditions. The main components of the LPSA Air Dryer are
a SeQual ATF LPSA Module and an oil-less air compressor.
Installation
IMPORTANT:
There are packaging materials that must be removed from under and around the
compressor. Do not attempt to operate the LPSA Air Dryer without removing these packaging
materials as damage may result.
Ensure that there is sufficient access space around the LPSA Air Dryer so that normal
maintenance and service can be performed. Also ensure that there will be a free flow of cooling
air around the compressor. Connect the unit to a grounded power source rated for the voltage
and current requirements stated on the label on the unit.
IMPORTANT:
The location of the LPSA Air Dryer must be well ventilated. Refer to the
recommendations in the Compressed Gas Association Guide P-8.1, “Safe Installation and
Operation of PSA and Membrane Oxygen and Nitrogen Generators.” Contact ClearWater Tech
if further assistance is needed.
IMPORTANT:
Choose a location for the LPSA Air Dryer that does not allow rain or
condensation to contact the unit.
Dry Air Hook-up
The dry air connection is a 1/8 inch female National Standard Pipe Thread (NPT) and is located
on the front of the LPSA Air Dryer. The hex nut bulkhead fitting should be stabilized with a 7/8
inch wrench to prevent rotation when making your connection to the unit.
