Siphon Micro Machines use a simple injector siphon gun for abrasive delivery. Micro models need smaller abrasive flow controls but not smaller machine features.
If you want clean operation with all the features found on Industrial models look to the Precision Etch model for micro flow control when processing those smaller parts or when you only have limited compressed air available.
Direct Pressure machines use a pressure vessel to pneumatically push the blast media through a single abrasive hose and out the blast nozzle to create faster abrasive velocity.
All our pressure machines use an ASME coded pressure pot with pot access service port. Because the direct pressure system pneumatically pushes the blast media, the abrasive has no weight making it possible to blast with very heavy abrasives.
