  • Ambient air is pulled through the inlet pre-filter and 80% efficient filter located on top of the isolator. The pre-filter traps large size particles to extend the life of the 80% efficient filter.
  • Air from the top inlet and from work zone is pulled by the blower, which creates positive pressure on the plenum that creates downflow. The proprietary plenum design forces more air into the work zone, increasing its pressure relative to the transfer chamber, thereby preventing contaminants from entering the work zone through the transfer chamber.
 
 
  • The ULPA downflow filters creates a laminar and particle-free ISO Class 3 environment inside the isolator to protect the work material inside the main chamber and transfer chamber.
  • Air from the work zone and transfer chamber 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 ULPA downflow filter again, it is re-circulated back to the work and transfer chamber. The high rate of airflow re-circulation helps to prolong the filter life and reduces the chance of ambient contaminants entering the work zone.
  • Approximately 10% of the purged air is exhausted through an ULPA 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 pre-filter and 80% efficient filter.
   

 

The Hospital Pharmacy Isolator blower system is designed for maximum energy efficiency and minimal maintenance.

  • Centrifugal, direct-drive, external rotor motors reduce operating costs.
  • Unique Esco motor/blower orientations minimize noise and vibration.
  • Built-in solid-state variable speed controllers are infinitely adjustable from Off to Maximum.

  Esco Centrifugal Fan with External Rotor Motor (left) vs.Conventional Fan with Standard Motor (right)

  • Esco cabinets use German made ebm-papst® permanently lubricated, centrifugalmotor/blowers with external rotor designs.
  • Integrated blades narrow the profile and eliminate need for a motor shaft.
  • Motors are selected for energy efficiency, compact design, and flat profile. The completely integrated assembly optimizes motor cooling.
  • All rotating parts are unitized and balanced for smooth, quiet, vibration-free operation.
