Congratulations on your purchase of a Labconco Purifier® HEPA
Filtered Enclosure or Purifier® Class I Filtered Enclosure. Your
enclosure provides personnel protection through superior
containment. It is the result of Labconco’s more than 50 years
experience in manufacturing fume hoods and more than 30 years
experience in manufacturing filtered enclosures.
These enclosures will effectively contain toxic, noxious, or
biohazardous particulates when properly installed and operated.
Each enclosure uses a single HEPA filter, which is rated at least
99.99% efficient for 0.3-micron particles. Additionally, an
accessory Odor Control carbon filter may be added to adsorb
nuisance odors from organic vapors, formaldehyde or ammonia
and amines. The Purifier enclosures offer many unique features to
enhance safety, performance, and energy savings. To take full
advantage of them, please acquaint yourself with this manual and
keep it handy for future reference. If you are unfamiliar with how
high performance HEPA filtered enclosures operate, please review
Chapter 4: High Performance Features and Safety Precautions
before you begin working in the enclosure. Even if you are an
experienced user, please review Chapter 5: Using Your HEPA
Filtered Enclosure, which describes the Purifier features so that
you can use the filtered enclosure efficiently. For hazardous
biological applications requiring user protection but not product
protection, Labconco recommends the purchase of a Class I
enclosure, which includes a UV light for general surface
decontamination. For general hazardous biological applications,
