Technology at a Glance	N/A Consistent outlet pressure dew points Slow Minimum purge air usage saves energy. Desiccant beds sized to prevent fluidization plus slow and complete regeneration prevents desiccant aging. Heavy-duty purge exhaust muffler for quiet operation. Non-lubricated, soft seated control valves promotes reliable operation.
Furnished in Cabinet for Easy Wall Mounting	N/A Fully assembled, piped and wired eases installation. Shipped with desiccant charge.
Front Mounted Control Panel	N/A Power on light Tower indicator lights On-off switch
Highly Accurate Solid State Timer	N/A Standard 4 minute cycle time delivers ISO Quality Class 2 pressure dew point. Flow deration delivers ISO Quality Class 1 pressure dew point.
Optional NGF Series Filter Packages	N/A Grade HF coalescing prefilter captures oil down to 0.008 mg/m³. Grade PF after filter removes solids 1.0 micron and larger.
How it Works	N/A Compressed air enters the dryer and is directed to Tower 1 by valve (A), and then to the dryer outlet through shuttle valve (B). A portion of the dried air is throttled to near atmospheric pressure by means of orifice (C). This extremely dry, low pressure air flows through and regenerates the desiccant in Tower 2 and is exhausted through purge/repressurization valve (D) and exhaust muffler (E) to atmosphere. After a set time, the automatic solid state timer closes purge/ repressurization valve (D) allowing Tower 2 to repressurize slowly. At the end of 2 minutes, valve (A) shifts and purge/repressurization valve (D) reopens. The main air flow is now dried by Tower 2 while Tower 1 is being regenerated.
Applications	N/A Critical applications include labs, hospitals, pharmaceutical manufacturing and other high-tech installations.
