RXPert Single Filtered Balance Systems are Class I biological safety cabinets designed for drug compounding and manipulation of pharmaceutical ingredients. They meet the USP † requirements for non-sterile compounding when ducted, and include a factory-installed canopy and damper for thimble ducting to the outside. Their true bag-in/bag-out HEPA filter disposal system provides safe filter replacement. 
 
In addition to the built-in blower (included), all models also require a remote blower (not included), ductwork and supporting base.
