In this Primed Insight we’re explaining how switching out a single air supply hose can increase blasting productivity by 12% each day.
A typical set-up of this nature employs a 2 inch air supply hose coming from a 1600 cfm compressor, flowing into an air dryer, and then to the MegaBlaster. These two hoses generally run a minimum of 25 feet each – thus 50 feet total.
The problem is, when you’re feeding 3-4 blasters with a nozzle pressure of 100 psi, you can lose up to 8 psi over that 50 feet length of hose.
For every 1 psi lost (beneath the recommended nozzle pressure of 100 psi) each blaster will lose 1.5% productivity. So a loss of 8 psi over 50 feet of hose equates to a 12% loss of productivity. Each day.
Simply swapping out the 2 inch air supply hose with a 3 inch hose results in ZERO pressure loss and thus increases productivity 12%.
For those who run TWO 2 inch air supply hoses – that’s an improvement. We highly recommend that if you can’t run a 3 inch hose. However you’ll still lose 2-3 psi, which is approximately 5% productivity loss.
NOTE: On our rental equipment, we install a 3 inch main bore inlet for a bull air supply hose as well as two 2 inch inlets to ensure you the best options to maximize nozzle pressure.
