Sponge-Jet's Sponge Blasting System™ consists of the Sponge-Jet Media Feed Units, Sponge-Jet Media Classifiers and a variety of different Sponge-Jet Sponge Media designed to offer a dry, low dust, low rebound, reusable abrasive or non-abrasive surface preparation system.

Sponge-Jet Feed Units deliver Sponge Media to the surface. We design and manufacture Feed Units to meet the specific flow characteristics of Sponge Media. An actuator inside the blast pot stirs the Sponge Media to keep it flowing, while an auger at the base of the unit controls the amount of media fed into the air stream. A pneumatic control panel provides precise adjustment of blast pressure and media feed rate.

Sponge-Jet Media Classifiers handle recycling chores. Blasted media is collected and processed through either an electrically or pneumatically powered sifter, which separates Sponge Media into three categories: oversized debris, reusable media, and fines (consisting of spent media and dust). Typically, between 60% and 90% of Sponge Media is reusable after each blast cycle.

Sponge-Jet Electric Media Classifier Height = 132 cm.  Width = 117 cm.  Length = 107 cm.  Weight = 277 - 340 kg. Features: High production rates, 1 classifier can service two operating Sponge-Jet Feed Units Electrical Equipment: 115 volt, single phase, 60 Hz. Explosion Proof Media Classifier is also available.

The heart of the Sponge-Jet System is our patented Sponge Media. Sponge Media is an open-cell, water reacted polyurethane sponge to which abrasives are chemically bonded during the production process. Each type of Sponge Media has different characteristics and blasting capabilities.

The Sponge

Profile

Recycle
(Nr.)

Red  Sponge Media (Steel Grit)
Heavily rusted steel or removal of heavy coatings where a high profile is required. Easily removes mill scale and elastomeric coatings.

Silver Sponge Media (Aluminum Oxide)
Fast cutting and aggressive. used for a wide range of commercial, industrial, marine and military coatings removal projects.

Brown  Sponge Media (Dupont Starblast)
Light to moderate rust, weathered coatings and old paint. Also used for profiling existing paint or between coatings for increased adhesion

White  Sponge Media
Coatings removal from fiberglass, aluminum, tile and other high-tech or sensitive substrates.

Green  Sponge Media
Grease and oil removal from hard substrates and heavy machinery without damage to hoses or fittings. Smoke and soot removal from concrete and steel.

Blue  Sponge Media
Cleaning smoke and soot from soft substrates such as sheetrock, plaster and soft woods. Up to ten times faster than wiping.
