SeQual Workhorse - Oxygen Concentrator Systems
These units are a turn-key industrial oxygen solution - just plug them in and they are ready to generate
oxygen.  They supply dry oxygen at a concentration of 90-95% from ambient air using an on-board
compressor and
ATF technology.  Available in sizes ranging from 8 to 23 SCFH and in various
voltages.

SeQual Quad - Oxygen Concentrator Subsystems
These industrial subsystem have no compressor.  Attach them to a compressed air supply and plug
them in.  They supply dry oxygen at a concentration of 90-95% from your compressed air using
ATF
technology.  Available in sizes ranging from 60 to 130 SCFH and in various voltages.
Pro-Dex Micro Motors, Inc.  Air Motors and Drills
Micro Motors, Inc. manufactures a line of high quality miniature air motors. Their 3/4" diameter and
compact profile makes them ideal for squeezing into applications where space is at a premium.  They
can be instantly reversed, will withstand repeated stalling and are well suited for use in contaminated
and wet environments.  Spark free operation makes them suitable for use in explosive applications.  
These units have built-in planetary gear boxes with speeds ranging from 1 RPM to 40,000 RPM.

SeQual ATF - Oxygen Concentrator Modules
These units are the heart of SeQual's ATF technology.  They are a basic building block component that
make it very simple to design your own industrial oxygen concentrator.  They produce dry oxygen at a
concentration of 90-95% from your compressed air.  Wire them to electrical power, supply them with clean,
regulated compressed air and they generate oxygen.    Available in sizes ranging from 8 to 32 SCFH and in
various voltages.

Compressed Air Powered Fans
Fans powered by air motors have the advantage of being intrinsically safer in damp, dusty or
explosive environments. Ideal for use in areas where you do not want to use electricity.  They
use compressed air for their energy source and run both cool and spark-free.  We currently can
not supply Tonson Inc. fans but have Gast powered fans available.

Parker Balston Cabinet Dryers
Parker Balston Cabinet Dryers utilize high efficiency coalescing Prefilters and hollow fiber
membrane technology to dry your cabinet without the use of electricity or moving parts. Reducing the
dewpoint of the air provides a clean, dry atmosphere inside the electrical cabinet and creates a slight
positive pressure to keep out unwanted dust found in many environments.
