This positive-pressure configuration allows filtration of
particles to ensure a uniform, contamination-free flow of
air to the work surface. It thus provides a mini-cleanroom
environment for particle-sensitive operations in microelectronics,
biotech, and many other industries. To construct your system,
select a stainless steel blower module and filter housing.
Note that two of each housing are required for twin (72"W
or 90"W) stations.
Select the appropriate blower for your application: a 740
CFM or a 1200 CFM variable speed impeller. The higher-output
blower is recommended for applications with multiple filters
or that require a high-level air flow. Finally, pick the filter(s)
that provide the cleanliness rating you require (refer to
the efficiency ratings below). The performance illustration
provides specific information on the air flow each filter
provides when used with the Terra blower module. Unless otherwise
specified, blower/filter modules come installed as indicated
in the illustration, with the higher-rated filter positioned
downstream in the filter housing.
