Description
Our P-G 400 spot blaster has been designed and built to meet the highest standards in metal and precious metal ceramics and in plastics technology. The robust, steel plate design and exclusive use of proven components ensure a long service life.
This spot blasting unit is modular in design. It can be fitted with two, three or four blasting units. Blasting material of 25 μ to 250 μ can be used without difficulty (polish blasting material, aluminium oxide and special blasting material). It ensures optimum adhesion conditions for bonding ceramics and plastics onto metal and precious metal, whatever the technique used.
The unit is particularly suitable for blasting before coating, polishing, removal of oxide and ceramics residue after baking, as well as for designing veneers and preparing ceramic chewing surfaces.
Details
Each blasting unit consists of a blasting material container with vibration mixing chamber, and associated blasting hose with hand piece. The sand jet is precisely initiated and stopped by an electro-pneumatic closure device activated by the foot switch.
The sand blasting unit has infinitely variable dosing and pressure regulators, which control the quantity of blasting material and the blasting pressure in the vibration mixing chambers. An absolutely uniform and reliable sand jet is
available above a working pressure of 0.5 bar. If the blasting material in the container falls to the reserve level, the relevant signal light on the panel flashes.

FAQ
What kinds of blasting material can be used with the P-G 400?
The P-G 400 can process blasting material with a grain size from 25 µ to up to 500 µ.
Why does my blasting nozzle clog up frequently?
Blasting material can sometimes contain a lot of impurities! Clean the blasting nozzle regularly and use only high-purity blasting material from Harnisch+Rieth.
Why does the unit keep blasting out material when the blasting process has ended?
The blasting hose of the relevant chamber is worn and needs replacing.
Why does the message: “Insert hand piece” appear even though the hand piece is already inserted?
The front of the hand piece (where the blasting material exits) features a ring magnet. This gets worn during blasting and must be replaced if you see this message.
Why doesn’t the unit automatically switch to the appropriate chamber when the hand piece is removed?
The only remedy to this problem is to replace the handle support bar.
