Product Benefits

Precision

From a working pressure of 0.5 bar, a constant and reliable abrasive flow with enormous precision is available.
Controlled and precise blasting of filigree objects due to the integrated quick-stop technology – start/stop of the blasting process within seconds.

Workflow

Setting and saving various working parameters (volume of abrasive, type of abrasive, grain size, pressure, blasting time, signal duration, illumination).
The set parameters are automatically activated and displayed when the blasting pen is removed.
Fast and safe work with the help of an individual adjustment of the dosing and pressure regulators enable an optimal air-and-sand mixture.

Savings

The technology of the P-G 400 allows you to work precisely, reliably and pleasantly, as well as saving more than 90% of blasting media compared to conventional systems, thus increasing your profitability.

Product Highlights

Mixing chamber Quick stop Detection system Product versions

Vibration mixing chamber technology

The unique vibratory mixing chamber technology reduces blast media costs by up to 90% through an optimal air-sand mixture, thus increasing your profitability. The vibratory mixing chambers are equipped with infinitely adjustable metering vibrators and pressure regulators, which are available to regulate the amount of abrasive and the blasting pressure. There are 40 different vibration intensity programs available.

Settings after consultation with Techn. Service possible:

– Changing the blasting chamber assignment or the blasting medium dosage
– Blast room lighting circuit
– Save the desired default settings (as priority)
– Recall the factory default settings

Quick stop technique

The foot switch controls pneumatic valves that immediately stop or release the blasting process. This technique provides controlled and pinpoint blasting of filigree objects and prevents unwanted after-blasting. (saving blasting material )

Automatic detection system

By removing the desired blasting pens from the blasting pen holder, the working parameters (dosage of the blasting medium quantity, type of blasting medium and the working pressure) are shown in the display and activated automatically. The connected extraction system starts up and provides a clear view into the blast cabinet.

Product versions

All product variants are individually set for you according to the configuration request of the blasting chamber occupancy. (type of abrasive, grain size, vibration technique)

Operating logic

Clearly arranged operating and control elements enable pleasant and precise work. Blasting pressure and abrasive delivery rate are set individually for each blasting system and shown in the LED display. (type of blasting medium, blasting system, grain size, dosing in 10 steps, blasting pressure in 0.1 bar steps)

The sandblast is conveniently triggered via the foot switch.

Fill level indicator

If the blasting medium reaches the reserve range, this is indicated by flashing of the corresponding control lamp on the panel and is visible on the display. At this point, a blasting medium reserve is still available for approx. 10 min of blasting.

Automatic switch-on

When any function is activated, the lighting and the connected extraction system are activated automatically. The device switches off after 15 sec. Inactivity automatically off (time is adjustable) and is therefore very energy efficient. Optionally, a suction unit is connected on the right or left.

blowout nozzle

A practical blow-out nozzle for manual and object cleaning is mounted within easy reach in the blast cabinet.

tank

Quick venting for rapid refilling and changing of the blasting medium with safe and easy-to-operate clamp closure technology prevents unnecessary jamming due to contamination.

We are very satisfied with the PG-400 unit.
It has functioned reliably and conveniently for many years and meets all requirements in everyday dental use.
Due to the precise adjustment possibilities for air pressure and jet volume, it is also very well suited for scientific studies,
where surfaces must be reproducibly conditioned.

Reinhard BuschLaboratory Manager Prosthetics UKSH Campus Kiel

The processing of the blasting unit as well as the quality are top class and simplify the daily work in the laboratory. Especially since the blasting sand consumption is very low. It is a dream in itself that the extraction system starts automatically and hardly any dust particles in the blasting chamber obstruct the view. Who knows the devices of Harnisch+Rieth, knows that you buy them only once! I am completely thrilled!

Support & FAQ

Welche Strahlmittelarten können mit dem P-G 400 verwendet werden?

Das P-G 400 kann Strahlmittel mit einer Korngröße von 25µ bis zu 500µ verarbeiten.

Warum ist die Strahldüse häufig verstopft?

Strahlmittel weisen teilweise starke Verunreinigungen auf! Reinigen Sie die Strahldüse regelmäßig und verwenden Sie nur hochreines Strahlmittel von Harnisch+Rieth.

Warum strahlt das Gerät nach beendigung des Strahlvorgangs noch nach?

Der Strahlschlauch der entsprechenden Kammer ist abgenutzt und muss gewechselt werden.

Der Pilzpuffer im Sperrventil muss überprüft werden.

Warum erscheint die Meldung: "Griffel einlegen", obwohl der Griffel eingelegt ist?

An der Vorderseite (Strahlmittelaustritt) des Griffels ist ein Ringmagnet, dieser wird durch das Strahlen abgenutzt und muss in diesem Fall getauscht werden.

Letztlich muss die Griffaufnahmeleiste ebenfalls überprüft werden, welche den Kontakt zum Handgriff (Ringmagnet) herstellt.

Warum schaltet das Gerät bei Entnahme des Griffels nicht automatisch auf die entsprechende Kammer um?

Bei diesem Problem hilft nur der Tausch der Griffaufnahmeleiste, oder der Ringmagnete am Griffel.

Der Strahlvorgang funktioniert nicht mehr, es kommt nur Luft

Die Mischkammer ist aufgrund unreinem Strahlsand oder falscher Sandkorngröße verstopft.

Das Dosiergehäuse (Mischkammer) besteht aus zwei Spaltmaßen welche voreingestellt zur Korngröße und Strahlsand sind. Bitte kontaktieren Sie unseren Service.

Druckverlust

Prüfen Sie die Wartungseinheit (Druckregler Eingang)
Prüfen Sie die Druckregler hinter der Blende (je Einheit)
Prüfen Sie die Pneumatikschläuche nach Knickungen
Prüfen Sie das Entlüftungsventil am Deckel (Strahlmittelbehälter)
Druckmessumformer defekt

Strahlmittelarten, Strahlmittelkörnungen verändern

Bitte kontaktieren Sie den Service von H+R. Die Veränderung der Elektronischen Einstellungen müssen gleichgesetzt werden mit der mechanischen Einstellung im Dosiergehäuse. Im Bereich 0-50µ bleibt die mechanische Einstellung bestehen. Im Bereich 50-250µ muss die mechanische Einstellung im Dosiergehäuse geändert werden.

(Bsp: 50µ Aluminiumoxyd zu 250µ Aluminiumoxyd. Die elektronische Einstellung lässt sich kinderleicht verändern, jedoch muss auch die mechanische Einstellung im Gerät vorgenommen werden.)
