During regular use, the Fuse Blast’s HEPA air filter collects powder and blasting media. Inspect the HEPA filter every 30 hours of blasting. Vacuum the filter when prompted by the touchscreen to prolong its lifetime and ensure proper operation.

If the HEPA filter remains visibly dirty after cleaning, it should be replaced.

1. Unlatch the HEPA filter door at the bottom front of the Fuse Blast.

2. Unlatch the wire retainer and swing it outward.

3. Remove the HEPA filter from behind the wire retainer.

4. Dispose of the used HEPA filter.
5. Install the new HEPA filter by inserting it behind the wire retainer with the pull tabs facing out. Ensure that the filter is fully and evenly seated in its housing.
6. Swing the wire retainer inward and latch it.

7. Latch the HEPA filter door shut.
8. Vacuum any powder that fell into the work area below the Fuse Blast.
