It is strongly recommended, per OSHA, NIOSH and ASHP, that this Isolator exhaust volume be exhausted to the outside. NuAire recommends the use of a canopy transition. Canopy transitions, sometimes referred to as a thimble or air gap exhaust transition, provide an air gap between the exhaust efflux of the Isolator and the transition. The air gap essentially insulates the Isolator from potential variations of airflow in the plant exhaust system, particularly if multiple items are connected to the same exhaust blower system. This bulletin details how to install such transitions on NU-NR797 Pharmacy Isolators. http://www.nuaire.com/download/bulletin/GTB0164.pdf General Technical Bulletin service@nuaire.com Thu, 27 Mar 2008 09:48:05 -0500 http://www.nuaire.com/download/bulletin/GTB0134.pdf General Technical Bulletin service@nuaire.com Thu, 27 Mar 2008 09:48:05 -0500 The topic of canopy versus hard connection of Class II, Type A2 Biological Safety Cabinet (BSCs) has long been a matter of discussion over the years.

A stable/repeatable response to airflow detection is achieved by using two thermistors: One that is self-heated and one that is measuring ambient. As air is passed over the thermistors the heated thermister is cooled, generating a difference in resistivity that translates into the flow rate. The second thermister provides the temperature compensated ambient reference. http://www.nuaire.com/download/bulletin/ATB0066.pdf Accessory Technical Bulletin service@nuaire.com Thu, 27 Mar 2008 09:48:04 -0500 NuAire disposable forearm pads were specifically designed and tested for NuAire Biological Safety Cabinets.
