FAQs
Access, Media, and Air-Supply Questions
Can WD816 clean combustion chambers?
It provides eight angled tubes and spark-plug-hole access, but use only when the exact vehicle procedure supports it and valve, sealing and recovery checks are complete.
What media does it use?
0.4–0.6 mm walnut abrasive, with less than 4 kg in the blasting tank.
What compressor is required?
More than 0.7 MPa and more than 0.4 m³/min of dry filtered air.
What differs by voltage?
Choose 1000 W at 110 V or 1400 W at 220 V and confirm the nameplate.
Can media always be reused?
Use fresh media whenever the machine or vehicle procedure requires it.
Does it guarantee no wear or 30,000–50,000 km results?
No. Results depend on the exact task, material, access, settings and service condition; no fixed durability or cost outcome is guaranteed.
