Product Overview

The Vaniman Mobile Problast offers fossil preparators a quality air abrasive system, at an affordable price. Interchangeable tanks and nozzles allow you to switch up your abrasive blasting media as often as you like, from 25-250μm. The Vaniman Air Abrasive Units are professional standard, rivaling the performance of units 10x the price!

This is an exceptionally versatile unit produced by Vaniman and made in the USA, for sale via ZOIC PalaeoTech. This fantastic unit is what you need for the preparation of a wide variety of fossils, with enormous flexibility at an economical price. Perfect as a standalone unit for the hobbyist or as a compliment to your existing air abrasive setup, allowing you to utilise different air abrasive powders without having to clean out the tank.

Interchangeable tanks and nozzles allow you to quickly and easily switch between different powders and different grain sizes (25-50μm; 50-100μm, 100-250μm) for maximum versatility. Arrives fully assembled.

The Master Mobile Problast differs from the Mobile Problast in its I/O (Insta-Off) mechanism, allowing for ultimate foot pedal control. The Mobile Problast will have some pressure bleed off and therefore powder flow through the nozzle when the foot pedal is released.

  • Built-in pressure delivery system including a 0-100PSI (0-6.8 Bar) adjustable filter regulator and foot pedal control. Recommended for use between 20-90 PSI (1.5-6.2 Bar); you’ll find a sweet spot depending on the powder and your application.

  • Handles all types of blasting media from 60 to 360 grit (25-250μm, 50-100μm tank size supplied as standard with base unit. 25-50μm and/or 110-250μm tanks can be purchased as optional extras). 

  • Designed for pinpoint accuracy on small or hard to reach areas via a variety of durable pencil point nozzles. Comes with a long-lasting crystal tip nozzle, and tungsten carbide nozzles can be ordered separately for higher precision (but they do wear faster).

  • Maximum longevity and maintainability with no metal wear points from the tank to the nozzle and “quick change” hose fittings.

  • Convenient 6-foot handpiece hose.

  • Incorporates a hose purging system between uses.

  • 1000ml tank size

  • Non-clogging flow design

  • 1-year warranty from date of purchase.

  • Can be used with Aluminium Oxide (53μm in the 50-100μm tank), Sodium Bicarb (match the grain size to the tank), Iron powder (150μm in the 100-250μm tank) and Dolomite (40μm in the 25-50μm or 50-100μm tank). NB Dolomite can be a bit temperamental due to the nature of the powder (although many preparators get used to this and have a few tricks up their sleeve).

In the box: Complete abrasive unit with frame, 50-100μm tank, connector tubing, water trap, nozzle fitted with crystal embedded tip. (We include a FREE 2m hose and PCL or EURO connector)

Mobile abrasive blasting system with one tank for all applications. System only – No Cabinet included. 

Must be used with a clean, dry air supply and dry abrasive powders. We recommend using Dropout® filters (available in the 'Air Filter' section of our shop. If you don’t have a clean air supply, do not expect any abrasive unit to work effectively. The unit is fitted with a automatic drain water trap, but we recommend using considerably more mechanisms to make sure your air is dry.

Must be used with a blast cabinet (not provided) and dust extraction system. These can be bought online in the dimensions of your choosing, or alternatively can be put together to your specifications as a DIY project or by a tame carpenter. Any questions, feel free to contact us.

Minimum requirement is a 2.2kW (3HP) >50l direct or belt driven air compressor (not silent).
