Blast-One Weekly Tips
Tip #100
Think big with your air supply hose!

Undersized air supply hose to the blast hopper results in friction loss. A loss of 1 psi results in a 1 1/2% reduction in production rate, i.e. a loss of 10 psi means a loss of 15% of production.

Minimum air supply hose should be 1 1/2", for 1 blast nozzle or 2" when using either a 1/2" or larger nozzle or multiple nozzles.

The illustration below demonstrates how the common practice of running two 1" hoses does not provide the same cross-sectional area as one 2" hose.
