Congratulations on your purchase of a Labconco Purifier® Vertical Clean Bench.
Your enclosure provides product protection. It is the result of Labconco’s more
than 30 years experience in manufacturing filtered enclosures.
These enclosures will effectively provide product protection from airborne
particulate matter. During operation, room air is drawn through the prefilter on
top, forced through the blower and then through the HEPA filter and diffuser. The
clean air in the work area in the enclosure meets or exceeds ISO Standard Class 5
conditions defined per ISO Standard 14644-1 and Class 100 conditions as defined
by Federal Standard 209E. The enclosure is set to deliver nominal downward
airflow of 40-55 feet per minute. Each enclosure uses a single HEPA filter, which
is rated at least 99.99% efficient for 0.3-micron particles. The Purifier enclosures
offer many unique features to enhance performance. 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 filtered Vertical Clean Benches operate,
please review Chapter 4: Performance Features and Safety Precautions before
you begin working. Even if you are an experienced user, please review Chapter 5:
Using Your Vertical Clean Bench, which describes the enclosure features.
