3. Technical Description
The n-psi dryer uses the pressure swing adsorption principle of drying compressed air,
utilizing two identical columns each containing a hygroscopic desiccant bed.
• Inlet filtration removes water, oil aerosols and particles (Inlet filtration supplied
separately).
• Wet air enters the dryer through the inlet valve and is directed into one of the columns.
• Each column contains a densely filled desiccant bed.
• Air then passes through the desiccant bed where any remaining moisture is adsorbed.
• Simultaneously, a small amount of dry filtered air is counter flowed down through
the other desiccant bed and exhausted to atmosphere, removing the moisture and
regenerating the desiccant bed.
• The dryer controller periodically switches columns after top end repressurization;
ensuring a continuous supply of dry air at constant pressure. The dryer can also be
controlled using a Zero Volt signal from the compressor. This energy saving mode
senses when the compressor is switched off and stops the dryer operation until the
compressor restarts.
• The dry air passes out through the final particulate filter (<1micron/ISO8573.1 Class 2).

4. Technical Specification
• Flow rate based on air inlet pressure of 100 psig (7.0 barg) and temperature of 95°F
(35°C).
• For dryer performance at other inlet conditions or -100°F (-70°C) dewpoint
requirements, contact [email protected].
• All dryers should be proceeded by a coalescing filter regardless of oil or oil free
applications, a nano M01 grade coalescing filter must be installed on the inlet to the
dryer.
