Prep/Master 3003GP Dust Collector

The Prep/Master® 3003GP is an industrial-sized vacuum for collecting large amounts of fine and toxic silica dust. There are no impossible applications for the 3003GP­—from the laboratory to the workshop, from mechanical engineering to the cement industry.

This model was developed in its first version, more than 15 years ago, to meet a wide range of requirements. It was recently completely redesigned in order to make it even more user-friendly and versatile, while improving its industrial capabilities.

(Hose sold separately and cut to desired 25 ft. lengths at purchase.)

Converting the Electrical Plug into 3-Phase or Single-Phase

The Prep/Master 3003GP dust collector plug can be configured as a “3-phase” or “single-phase” machine based on your specific needs.

1) 3-phase:
Outlets located on either side of the distribution box are available for electrical power to a grinder or shot blaster. In order to run these machines, the vacuum’s electrical plug must be configured as a 3-phase.

2) Single-phase:
If you want to use the vacuum as a stand-alone machine, then a 220V single-phase configuration is an option.
A good example of this would be — using the vacuum alongside a propane grinding machine. Since the propane requires no outlet for power, the vacuum could simply be run from a 220V electrical outlet.

For an explanation on how to configure your electrical plug to a single-phase, watch the following video:
