Figure 14: H13 post filter
The following are installed as subsequent separators or post filters:
- HEPA filter H13 (Pos.
„
)
- Metal mesh follow-up separator (pos.
…
)
The separation performance of the H13 follow-up separator is higher than that of the metal mesh
follow-up separator (see Chapter 7.1.5). The metal mesh follow-up separator is not recommended
for processing installations which produce smoke and vapor.
The H13 post filter will become clogged in the course of its operation, diminishing the AFS air purification
device's suction output.
If the H13 post filter is clogged or if the air current is significantly reduced due to a saturated filter, then the
H13 post filter must be replaced. To do so, undo the M6 screws on the terminal strips so that the post filter
can be pulled out.
The H13 post filter cannot be cleaned.
Replacement interval: Replace when there is a noticeable reduction in the device’s extraction performance
due to oil and emulsion residue deposits, or hardened oil.
To replace, undo the M6 screws on the terminal strips so as to allow the suspended particle filter to
be pulled out. When fitting a new post filter, the filter’s rubber sealing strips must be on the suction
side (in the terminal area).
The filter bags must be vertical.
If the H13 is not promptly replaced, it may tear. There will therefore be no filtration effect and the
AFS air purification device will be inoperative. The AFS air purification device must be turned off
immediately and a new H13 post filter must be installed.
Parts will have oil and coolant lubricant residue. Proper and ecologically responsible disposal is
absolutely necessary.
