Negative pressure mode with the ACS located inside of the containment zone:
The ACS pulls in contaminated air, filters out contaminants and propels
the filtered air outside the containment zone through flexible ducting
to negatively pressurize the work area. |
 |
Negative pressure mode with the ACS located outside of the containment zone:
Inlet ducting is used to pull contaminated air out of the zone to negatively pressurize it.
Contaminants are removed by the ACS unit which is typically located
adjacent to containment barrier so contaminated air can be fed directly
into the inlet. Filtered air is ducted outside or to another area as
required.

 |
Continuous air cleaning and recirculation:
The ACS is located within the containment zone with no inlet or exhaust
ducting, so there is no affect on room pressurization. The ACS
accelerates the removal rate of airborne contaminants. |

Positive pressure:
HepAssure Air Control Systems can also be used to create and maintain positive pressure zones. |
