Nozzle pressure is everything
For standard efficiency and productivity our experience tells us that a minimum of 100 psi is needed coming out at the nozzle. Each drop of 1 psi causes a 5% drop in productivity. Many blasters read the compressor gauge and believe that to be their actual blasting pressure; which is totally false in nearly every single case we’ve examined.
The Proper Way To Test Your Blast Pressure
With a BlastOne Pressure Gauge Kit, you can simply measure your blasting pressure. While the abrasive flow is open follow these 3 simple steps:
- Insert hypodermic needle onto nipple at the bottom of the gauge.
- Slowly insert the needle into the rubber hose a few inches back from the nozzle holder. Aim the needle toward the end of the nozzle, at a slight angle. Insert slowly until you get a constant reading. Are you getting 100psi?
- Record reading and remove needle. Pack away for next time.
The Pressure Test Kit is great for checking your entire system set-up
Where are losing pressure from the compressor to the nozzle? Below are two hotspots to measure to accurately diagnose where you’re losing pressure.
- Always insert the needle at an angle in line with the direction of the air flow. Not against the air stream.
- On long hoses, test the pressure at both ends – you’ll be shocked to see how much pressure drops just running the length of a hose!
- We recommend two kits to simultaneously test air going into your blast pot versus air pressure exiting the pot. Significant pressure loss is most likely due to equipment and/or accessory leaks, or issues with your compressor.
