AECR
Remote Feed Air Eraser
with Quart Container
OPERATING INSTRUCTIONS AND REPLACEMENT PARTS
INTRODUCTION:
AECR Remote Feed Air Eraser with Quart Cup offers greater
freedom of movement through use of a larger abrasive
compound container which feeds abrasive by hose to the AECR
Eraser. The large container allows the operator to work longer
between refills.
The AECR Eraser is used by:
• Dental professionals to improve aesthetics of castings or
obtain occlusal relationship analysis of gold castings.
• Hobbyists to etch decorative glass or quartz.
• Museums and Manufacturers to clean antique jewelry
and fine parts.
• Lithographer to highlight halftones and erase defects
without marring the surface or leaving a smudge.
The AECR Eraser can only be used with the following abrasive:
• AEX- Fast Cutting Compound
The most popular AEX- Compound has a particle size from 85
to 25 Microns, with an average 50 Microns.
OPERATION:
1. Connect A-1/8-6MT Air Hose Assembly as follows:
a. Small coupling nut to valve casing.
b. Large coupling nut to Air Supply.
2. Connect AE-73 Hose Assembly to AE-51 Cover
Assembly. Make sure all connections are secure.
a. Small coupling nut to valve casing (#24).
b. Large coupling nut to outlet casing (#29).

the speed and abrasive action desired. The higher the
pressure the faster the cutting action. Do Not Exceed
50 lbs. Air Pressure.
