Simple, Reliable Blast and Recovery Systems Educt-O-Matic Clemco's smallest closed-circuit tool, the hand-portable Educt-O-Matic goes anywhere and operates on just 90 cfm of air at 90 psi. The operator controls blasting and recovery with a trigger handle. Pulling the trigger just slightly starts the vacuum recovery. Pulling the trigger all the way starts the suction blast system. The compact conical hopper contains the abra-sive and meters it into the blast system. Air rushing through the Educt-O-Matic's mixing chamber draws the abrasive into the airstream and propels it out the nozzle. The blast head swivels to allow blasting at any angle and the rubber boot traps the dust and abrasive. The vacuum captures the reusable abrasive particles and sends the dust and bro-ken abrasive to the dust bag. The Educt-O-Matic cleans an area about one inch wide. After blasting, the operator releases the trigger about halfway to stop blasting, but continues vacuuming for two or three seconds to recover any remaining dust and abra-sive. Fully releasing the trigger stops the vacuum system. The Educt-O-Matic is designed for use with steel and iron grit. The simple cotton bag traps dust. Educt-O-Matic with angle attachment for inside corners.
Comet The Comet packs the power of an industrial suc-tion blast, recovery, and reclaim system into a package not much larger than a shop vac. The wheel-mounted Comet includes its own pressure regulator, pressure gauge, and moisture separa-tor. The 150-cfm media reclaimer operates on household current - 115v, 1 Ph, 60 Hz. The dust col-lector houses 14 cotton sateen tubular filters. With 20 feet of recovery hose, the Comet lets the operator move unencumbered about the work site. The operator turns on the electric power to begin vacuum recovery, then starts and stops blasting with an in-line switch at the blast head. A flexible non-marring brush on the blast head con-tains the dust and abrasive, and glides smoothly across most surfaces. Specialized brushes allow the Comet to clean inside angles, outside angles, and uneven surfaces. A compartment atop the Comet stores extra brushes and other accessories. The Comet uses 47 cfm of air at 80 psi, and cleans a path about 1-inch wide, at up to 36 inches per minute. It works best with fine mesh glass bead or aluminum oxide. Aggressive media such as aluminum oxide, silicon carbide, and garnet subject the components to rapid wear; order optional boron nozzles and tube inserts when using these media. The Comet is not designed to handle sand, slag, or metallic media such as steel grit.
Super Comet The Super Comet pres-sure-blast system delivers an enclosed high-velocity stream of abrasive to the surface being cleaned. The closed-circuit blast head features a 3/16-inch nozzle and multiple brushes for cleaning inside and outside angles, and uneven surfaces. It cleans a path about 1-inch wide up to 72 inches per minute, consuming 45 cfm when the nozzle is new and up to 70 cfm when worn, at 80 psi. The system's portable cart moves easily on smooth, level surfaces. A 20-ft recovery hose lets the operator reach most surfaces with ease. The standard unit features a tungsten carbide nozzle and 1/2-cubic foot, ASME-code blast machine with adjustable metering valve. The system handles most common, non-metallic, recyclable, 60- to 280-mesh blast media. Aggressive media, such as aluminum oxide, silicon carbide, and garnet, subject the system to rapid wear; order optional boron nozzles and tube inserts when using these media. The Super Comet is not designed to handle sand, slag, or metallic media such as steel grit. The built-in storage hop-per holds recovered media to automatically refill the machine when the operator pauses and releases the con-trol handle. And the system includes an air filter/mois-ture separator, pressure regu-lator, and gauge. The integral
dust collector houses cotton sateen tubes to trap dust and fines, and drop them into a convenient slide-out tray for easy disposal. The
dust collector houses 12 cotton sateen filter tubes.
