- Heavy-duty purge exhaust muffler installed for quiet operation.
- HF Prefilter & PF Afterfilter options are included and installed as shown.
>>Grade HF coalescing prefilter captures oil down to 0.008 mg/m³.
Grade PF after filter removes solids 1.0 micron and larger.
Applications: Critical applications, including labs, hospitals, pharmaceutical manufacturing and other high-tech installations.
- Standard 4 minute cycle time delivers ISO Quality Class 2 pressure dew point.
Flow deration delivers ISO Quality Class 1 pressure dew point.
- Consistent outlet pressure dew points
- Slow and minimum purge air usage saves energy.
- Desiccant beds sized to prevent fluidization.
- Slow and complete regeneration prevents desiccant aging.
- Non-lubricated, soft seated control valves promotes reliable operation.
How it works:
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.
