Prefilter No. 3859200, -01, -02, -03
The Prefilter provides a convenient means to prevent large particles from being pulled
into the blower and HEPA filter of the biological safety cabinet. The Prefilter is a simple
addition and easily replaced with its self-adhesive glue lines.
Please note that this accessory was tested in the Purifier Logic
TM
Biosafety Cabinet at
NSF and validated to have no adverse affect on containment.
Installation Procedure
Note: The work surface of the cabinet and the towel catch must be thoroughly
decontaminated before removing either.
1. Remove the work surface by lifting the front
edge with the knobs. Slide the work surface
forward to disengage the rear tabs. Support
the underneath side with one hand while
stabilizing the front edge with the other.
2. Lift the front end of the center support
straight up to release it from the locating pins
(A). Set the support aside in the work area.
3. Access the towel catch by pivoting the bottom
out toward you (B). Surface decontaminate
the towel catch before removing it from the
cabinet.
4. The Prefilter is adhered to the inside of the
towel catch by aligning the glue strips with
the webs on the towel catch. Allow the
Prefilter to overhang the ends of the towel
catch by approximately one-half-inch (125mm).
5. Reinstall the towel catch by sliding it back
into position, ensuring that the two slots on
either end of the towel catch properly engage
the rails on the rear of the duct, as shown in
Figure 6-2. Also ensure that the DOP
Sampling Line (the clear tube with a black
cap) either passes through a hole in the towel
catch, or passes along the outside edge of
the catch without being kinked.
