The New Jersey State House was built in 1792, and is the second oldest state house still in use. As part of a $300 million renovation, the restoration of the impressive gold dome structure was undertaken. This 160-foot tall (from floor to apex) dome is where sponge media blasting came to the rescue with the solution to a complex surface preparation and historical preservation problem.
Choosing the best Sponge Media Feed Unit™ can seem like an intimidating task. Sizes, features, and portability vary between models, but they all do the same overall task of mixing blast media with compressed air for abrasive blasting. Some units like the EX product line are for usein potentially combustable, flammable atmospheres, while other units like the Rasp Xtreme and the 100-HP are optimized for portability.
