SG130 is a dustless-blasting head for suction-fed airblast machines. Its annular-gap air nozzle surrounds the abrasive feed, producing uniform pressurization and a stable vacuum to reduce turbulence, control wear and improve repeatability.

Conventional suction-fed heads supply abrasive laterally and compressed air centrally. This arrangement can create unilateral air-nozzle wear and uncontrolled turbulent flow.
Turbulence reduces blast-head efficiency and can accelerate wear in the nozzle and the complete head.
The SG130 uses a special annular-gap nozzle with a documented 0.1 mm air outlet. The narrow outlet accelerates compressed air around the abrasive supply.
Because the annular gap forms a complete radius around the feed, pressure is distributed uniformly across the nozzle section rather than concentrated on one side.
Avoiding turbulence supports a constant vacuum, which is important for reproducible suction-fed blast results. The design is intended to improve the stability of abrasive acceleration and surface treatment.
The documented benefits include reduced nozzle wear, improved result reproducibility and lower interruption risk from uneven component wear.
The head is designed specifically for suction-fed airblast machines and was introduced in 2013. Nozzle condition, annular clearance, abrasive feed and vacuum stability should be checked together during maintenance.
A change in blast pattern or recovery behavior can indicate wear or blockage and should be investigated before quality drifts.
