Boron Carbide Nozzles
If you are blasting with Aluminum Oxide, Silicon Carbide,
Steel shot or other hard abrasive and not using Boron Carbide nozzles a lot
of money is being wasted. Look at the chart below to see an estimate of
service life for different types of nozzles. The higher cost of Boron Carbide
nozzles is very easily justified. Not only will you get longer life but save
time in less nozzle change over, use less air and have a longer consistent blast
pattern which will make your production more efficient
LONGER LIFE - REDUCE DOWN
TIME - LOWER COST PER USE - MAINTAIN EFFICIENCY
Boron Carbide nozzles are
the longest lasting nozzles
They cost more but pay for themselves, easily
A good Deal
