Pressure Blast versus Syphon Blast

In the majority of applications, the Pressure Blast is favored because of it's speed and versatility. The pressure blast is a system in which the abrasive is in a closed pressurized tank with one hose carrying a mixture of compressed air and abrasive from the tank to the nozzle. The Syphon Blast is a system in which two hoses, one for compressed air and one for the abrasive syphon, are connected to a gun which has a nozzle and an air jet.

Advantages of Pressure Blast:

Faster - about 3 times faster than syphon blast.

Particle velocity range - many pressure blasts are designed to operate from 1 to 125 psi.

Control of abrasive flow rate - the abrasive valve and the choke valve permit accurate control of the abrasive flow rate.

Operator fatigue - Reduced pressure blast nozzles are more compact and lightweight.

Maintenance - There are no air jets or gun bodies to wear out.

Longer abrasive life - Blast cleaning at high pressure greatly reduces abrasive life.

Pressure blasts throw more abrasive but at low pressure.

The abrasive breakdown per unit cleaned is reduced.

Can clean cored spaces.

Higher particle velocity - Critical in getting "tooth" on a blast cleaned metal surface.

Nozzle Variety - Can use special nozzles such as angle nozzle, cone blast 3600 nozzles, bottoming nozzles, and rubber tube nozzles.

Advantages of Syphon Blast:

Lower price - Pressure blast cabinets usually cost more than syphon blast cabinets of similar size.

Shorter Abrasive Change Time - Most syphon blast cabinets are designed so the abrasive can be changed in 1 or 2 minutes. Most pressure blast cabinets require 5 to 10 minutes.

Quicker recycling of Abrasive - In syphon blast cabinets, the abrasive is continuously re-cycled without interrupting the blast. In a pressure blast cabinet, the spent abrasive in the hopper will re-charge into the abrasive tank via the automatic fill valve after blasting stops, about 20 seconds.

In a choice between pressure blast and syphon blast where pressure blast can give 3 time faster production, profit argues very strongly in favor of pressure blast.
