Features
- Fully welded stainless steel 316L internal chambers with stainless steel 304 external housingg
- Exhaust air is double-filtered through high-quality ULPA filters (per IEST-RP-CC-001.3) with typical efficiency of >99.999% for 0.1 to 0.3 micron particles, better than HEPA filters.
- An integrated pass-through with interlocking doors permits materials transfer without risk of contamination
- Single-piece, leak-tested glove assemblies which guarantee maximum protection.
Principle

- Ambient air is pulled through the inlet prefilter located on top of the isolator. Air from the top inlet and from work zone is pulled by the fan which creates a positive pressure on the plenum that creates downflow. The HEPA (H14) downflow filter creates a laminar and particle-free ISO Class 5 air cleanliness as per ISO 14644-1 (equivalent to Class 1 as per US Fed Std 209E) inside the isolator to protect the work material inside the main chamber and pass-thru. Air from the work zone and pass-thru is quickly purged out by the fan to keep the area clean. The fan pulls approximately 90% of the purged air back to the plenum and after passing through the HEPA (H14) downflow filter.
- The high rate of airflow recirculation helps to prolong filter life and reduces the chances of ambient contaminants entering the work zone. For a recirculating model, approximately 10% of the purged air is exhausted through an HEPA-filter to prevent heat build-up inside the isolator that can be detrimental to drug compounding. This exhausted air is replenished by ambient air coming from the top inlet prefilter and a filter with 80% efficiency for positive pressure model. For a Total Exhaust/Single-Pass Model, 100% of the air is exhausted out of the isolator.
