This compact air abrasive unit has been developed for precise and smooth fossil preparation.Its integrated airflow ensures a steady stream of abrasive powder without clogging or clumping, thanks to controlled turbulence. Originally designed for the use with iron powder, the wear-resistant carbide nozzle guarantees a long service life, even with intensive use. This device can be used with other media as well, as long as the abrasive has good flow properties.The equipment includes a high-quality pressure reducer with integrated pre-filter and adownstream micro filter (99.99 % separation efficiency). Featuressuitable for grain sizes 50-220µmimmediate start/stop functionair-reversal feature for quick ventilation and cleaningconvenient and clean refill via screw-on funnelpressure tested, corrosion-resistant abrasive tank made of stainless steelconnection port for external devicespressure regulator with water separator and pressure gaugeblasting pen and round nozzle 0.8 mmquick coupling to compressed airTechnical dataOutside measures: 350 mm (L) × 330 mm (W) × 500 mm (H)Abrasive tank: stainless steel, 2 liter volume, corrosion-resistantBlasting nozzle: Ø 1.0 mmMixing nozzle: Ø 1.0 mm and Ø 0.8 mmHose length: 1 meterInlet pressure: 6 - 10 barWorking pressure: continuously adjustable from 0.5 - 10 barConnections:- pressure reducer with pre-filter and micro filter- connection WN 7.2- pneumatic shut-off for pinch valve (optionally with foot switch)- connection port for external devicesWeight: approx. 4.7 kgColors in product photos may differ from those of the original product for technical reasons.Our pictures are for reference only, when purchasing you will receive a product of equivalent quality.
