ER Series Air Eraser
Steel Tip W/Carbide Insert
OPERATING INSTRUCTIONS & REPLACEMENT PARTS
APPLICATIONS:
The ER Air Eraser is a versatile instrument that can erase
color errors and act as an etching tool. It is used by
hobbyists and manufacturers to clean jewelry and fine
parts, remove discoloration, rust and corrosion, etch glass
or cut monograms. It is used by lithographers to highlight
half-tones and erase defects without marring the surface or
leaving a smudge. It is used extensively by model
railroaders for weathering railcars and accessories.
DENTAL INFORMATION:
Indispensable in occlusal relationship analysis of gold
casting. By dulling the high polish on the surface of inlays
and crowns it is possible to identify minute occlusal
contacts with their opposing teeth, without the discrepancy
of any inter-occlusal thickness of material. The dull surface
of a casting shows the markings of any tape, carbon or
articulating paper with superior fidelity. When adjustments
have been made, the surface can be dulled again and
further analysis carried out.
OPERATION:
For general erasing, clean dry air at pressures of 30 to 65
p.s.i. may be used. To be sure of satisfactory performance,
the R-75 regulator will remove within it’s rated capacity
water, oil, and other impurities from your source of air
supply. The addition of an “optional” inline MT moisture trap
will insure maximum impurity separation. Expect a slight
trickle of abrasive to flow out after H-155 Button has been
released. This is caused by air pressure in the cup being
relieved.
1. Attach airhose coupling to AE-63 Valve Casing.
2. Unscrew ER-47 Cup.
3. Fill cup 3/4 full with clean dry AEX abrasive and
replace ER-47 cup. Tighten cup securely.
4. To prevent leaks, do not get any abrasive on the cup
threads.
5. Regulate air pressure for erasing on paper surfaces
to approximately 30 p.s.i. Use a higher air pressure
of 45 to 65 p.s.i. for metal, gold castings, plastic or
glass work.
6. Hold the Air Eraser the way you would a pencil.
Move the Air Eraser with the AEC-34R Tip about
1/8" to 1/2" above the work surface. Adjust to
achieve results desired.
7. Adjust ER-44 Valve Stem to the lowest point to avoid
excessive use of abrasive.
8. For work requiring fast, heavy abrasive cutting, use
AEX Fast Cutting Abrasive and high air pressure.
Hold tip of the Air Eraser very close to the working
surface to cut faster. Hold at a distance for blending
and broad coverage.
COMPRESSORS:
The Paasche “DA400R” Air Compressors can be used
with the ER Air Eraser at pressures up to 55 p.s.i.
The “DC850R” Compressor can also be used and has
a dual quick connect feature for running (2) ER Air Erasers,
or (1) ER and (1) Air gun to blow off area.Pressures up to
65 p.s.i.
