Install and remove HE filter, filter/cartridge, prefilter, spark arrestor and cover
Install and remove the filter/cartridge in non-hazardous locations only.
1. Inspect the filter/cartridge to be installed:
• Filter/cartridge is intact with no tears, cracks, distortion or other damage.
• The inner circular gasket is present and intact with no tears, cuts or distortions. Wipe the filter seal with a clean cloth
if necessary. Dispose of and replace filter/cartridge if damage is noted or suspected.
NOTE:
The 3M™ Versaflo™
Powered Air Purifying Respirator TR-600/TR-800 Filter/Cartridge Assemblies have both an inner circular gasket
(Fig. 3-6) and outer rectangular barrier (Fig. 3-5). The inner gasket is the primary seal between the filter and blower.
The outer barrier acts to keep dirt and debris from behind the filter.
2. To install the filter/cartridge:
• Confirm the TR-800 is powered off.
Do not install or replace filter/cartridges while the motor/blower is running.
Option 1: Using the filter/cartridge with prefilter/spark arrestor and filter cover.
Fig. 4 (Recommended for most applications).
NOTE:
Use the specified filter cover for the filter/cartridge. See “Specifications” section for correct pairing.
• Hold the filter cover so it faces down (Fig. 4-1).
• (If required) insert the metal mesh spark arrestor/prefilter into the cover, ensuring the cutouts are aligned properly
(Fig. 4-2).
• (If required) insert the foam prefilter, ensuring the cutouts are aligned properly (Fig. 4-3).
• Insert the filter/cartridge into the filter cover ensuring the bottom latching tab snaps into place (Fig. 4-4). The
filter/cartridge label must be visible in the cover window (Fig. 13).
• Place the hinge side of the filter/cartridge into the motor/blower (Fig. 5-1) and snap latch side into the filter latch
(Fig. 5-2).
• Gently tug on filter/cartridge to ensure proper attachment at both sides.
Option 2: Using the filter/cartridge without the filter cover.
(May typically be used in applications when filter/cartridges are changed very frequently to reduce potential for
cross-contamination.)
NOTE:
Using the filter/cartridge without the filter cover leaves it more susceptible to damage from external forces and
liquid spray.
• Place the hinge side of the filter/cartridge into the motor/blower hinge (Fig. 5-1) and snap latch side into the filter
latch (Fig. 5-2).
• Gently tug on filter/cartridge to ensure proper attachment at both sides.
