Compressed air blasting using a solid blasting
agent
This method is suitable for local and gradual very fine
treatment of steel parts with rust film (propeller shaft).
The Compressed air blasting contains no harmful sub-
stances, is approved by the competent authorities and
guarantees optimum cleaning. The granulates used are
of sizes 40 to 60 μ . The achievable surface roughness
is between 0.5 and 1 μ, which corresponds to ultra fine
machining of surfaces.

NOTICE
Exhaust valves and intake valves may NOT undergo a compressed air blasting
treatment with solid blasting, strong abrasive material. Due to this surface treat-
ment one does gain a microscopic surface which does allow as a consequence
the adhesion of fuel residues. These deposits are then involved in a chemical re-
action (especially of the sulfur and lead content of AVGAS) with the valve materi-
al. This effect may cause hot-gas corrosion on the affected parts.
