– heavy duty blast hose with quick coupling and stainless steel earthing
– one control cable (for start/stop and gun light!)
– protecting sleeve
• Dry ice or air-only blasting option
• Hour counter
• Safety soft start
• Start safety protocol

Intuitive control panel:
• Emergency stop and ON/OFF buttons
• Robust industrial grade single touch control buttons :
– dry Ice feed rate: LED-indicated (COB 62(plus)) or digital indication (COB
71(R))
– gun light: 0-5-10 LEDS
– abrasive module selector (LED-indicated) on COB 62plus and COB 71(R)
• Blast pressure regulator and manometer
• Remote control activator on COB 71R

Fast and easy connections:
• Quick coupling for blasthose
• One multifunctional control cable to gun
• Power cable
• Connection for optional earth cable
• Compressed air inlet

Pellet crusher
• Crushes dry ice pellets for cleaning delicate surfaces and objects
• Easy to mount at machine and/or gun (in a matter of seconds with quick coupling)
• Nozzle-independent :
– can be used with every nozzle
– nozzle does not have to be exchanged or removed

Electrically isolated blastgun MG1003
• To clean live (low- to mid-voltage) equipment
• Full plastic isolated blastgun for applications where non-conductive tooling is a safety requirement

The Abrasive Module:
• Combines benefits of dry ice and abrasive blasting
• Allows to mix a controlled quantity of abrasive granulate in the dry ice flow
• Ecological : reduces significantly the abrasive granulate requirements compared to conventional abrasive blasting (less secondary waste, less clean-up)

The system consists of:
• stainless steel module easily mountable at the front of the machine
• additional abrasive granulate hose
• a special abrasion resistant nozzle for standard gun

Some applications:
• rust removal, paint stripping,…
• stubborn material removal
• surface roughening before painting,coating,…

We can offer different kinds of abrasive granulate going from fine to rough depending on the required abrasive effect (from 0.1 mm to 2 mm).
