ALC 3/16 Pressure Pot Blast Nozzle

The 3/16″ uses 50 CFM and covers 3 to 3.5 sq ft/min - right for shops whose compressor cannot sustain the 80 CFM demand of the 1/4″ but where the 5/32″ is too slow for production volume. It fills the gap between mid-size and full-production blasting output without requiring a 20 HP compressor.

The 3/16″ nozzle draws 50 CFM at 80 PSI. A 15 HP two-stage compressor sustains this bore in production. If your compressor pressure drops during blasting at this size, its sustained output is below 50 CFM - use 5/32″ instead or increase compressor capacity before running 3/16″ in production.

The 3/16″ bore handles auto body panels, larger structural components, agricultural equipment, and production work where the 5/32″ is too slow. At 3 to 3.5 sq ft/min and 400 lbs/hr, it blasts production volumes efficiently without requiring a 20 HP industrial compressor setup to sustain the session.

The 3/16″ covers 3 to 3.5 sq ft/min at 400 lbs/hr using 50 CFM. The 1/4″ covers 4 to 4.5 sq ft/min at 500 lbs/hr using 80 CFM. The 1/4″ is about 25 percent faster but requires 60 percent more air. The 3/16″ is the right choice when compressor output is the limiting factor.

Replace the 3/16″ nozzle when blast coverage per pass shrinks, when the bore shows visible widening, or when throughput drops below 400 lbs/hr at standard pressure. Ceramic wear at this size is gradual but consistent. Inspect the bore after each 30 to 40 hours of production blasting.
