How much compressed air does a blast nozzle need?

A No. 6 nozzle (3/8 inch) at 100 PSI pulls roughly 170 to 200 CFM, and consumption climbs sharply as the orifice wears oversize. Use the Compressor Air Demand calculator with your nozzle size and pressure to size the compressor, then check Blast Air Pressure Loss for hose and coupling drops. Aim to keep at least 90 PSI at the nozzle; every 1 PSI lost cuts productivity about 1.5 percent.

How do I calculate blast media consumption for a job?

Consumption depends on nozzle size, air pressure, and how much abrasive breaks down per pass. The Blast Media Consumption calculator estimates pounds per hour from your nozzle and pressure, then multiplies by blast time from Blast Coverage Completion Rate. Pair it with Media Reclaim Value to net out recoverable abrasive; recyclable steel grit may last 200-plus cycles, while expendable garnet is single-use and dominates cost.

What is a fair blast cost per square foot?

Rates typically run from a couple dollars per square foot for light SP6 commercial blast up to considerably more for SP10 near-white on complex geometry. The Blast Cost per Square Foot calculator combines Blast Operator Labor Cost, media, Blast Compressor Energy Cost, and coverage rate. Feed the result into Blast Quote Margin so masking, part rotation, and expected Blast Rework Cost are all built into the bid.

How do I keep shot peening within Almen intensity spec?

Peening below the lower Almen intensity limit leaves parts under-stressed and prone to fatigue failure, so you need margin against nozzle and media wear that reduces intensity over a run. The Shot Peening Intensity Lower-Limit Margin calculator shows how much headroom you have above the minimum spec, letting you set a media replacement or verification interval before saturation curves drift out of tolerance.

When should I replace dust collector filters in a blast room?

Filters need replacing when differential pressure climbs past the collector's rated limit, usually around 4 to 6 inches of water gauge, which starves airflow and hurts visibility. The Dust Collector Filter Replacement Interval calculator estimates service life from dust loading and pulse cycles, while Dust Collector Loading confirms your collector CFM matches the blast room's dust generation rate for the media you run.

How much does nozzle wear actually cost per year?

A worn tungsten carbide or boron carbide nozzle grows its orifice, spiking air and media use while dropping pressure. The Blast Nozzle Wear Cost calculator combines nozzle replacement price, service life in hours, and the extra Blast Compressor Energy Cost from oversized flow. Boron carbide nozzles cost more upfront but can last 500 to 1,000 hours versus 20 to 40 for tungsten carbide, often winning on total cost.
