Filtration Management, Inc., offers a fully
computerized robotic filter scanner for use during the performance
evaluation testing and certification of HEPA/ULPA filters and cleanrooms thereby affording complete control,
repeatability and accuracy
during the qualification of filter integrity.
The system employs microprocessor
controlled precision linear drives to provide either automatic or manual
filter scanning in an X-Y direction. Multi-directional capability
allows use in either vertical or horizontal airflow configurations.
Operator definable parameters include
individual filter identification, upstream particle concentration, allowable
filter penetration (alarm condition), filter size, scan width, and filter
scan traverse rate.
During the automatic operation, signal
data from the laser based airborne particle counter is tied to the X-Y
position where it is collected by the isokinetic probe. This data is
analyzed in real time to qualify the filter integrity. Should a
condition be found which exceeds allowable filter penetration, the position
of the leak and probe data are pictorially displayed on the system monitor
and saved on the hard drive. Data is reported and saved accordingly to
the individual filter identification number.
The manual operation mode will allow the
operator to revisit a location where an alarm condition was found
during the automatic scan. The operator can either: (1) Enter the X-Y
coordinate where the leak occurred and have the system automatically drive
the probe to the specified location; or (2) Randomly drive the probe to any
specified location via the track-ball on the computer keyboard.
