The SPE 20ES shot blaster is a top - notch machine designed for serious contractors aiming for high productivity. It's electrically powered, perfect for preparing concrete floors and equally effective on steel surfaces. This series can obtain electrical safety certification for petrochemical refinery use. It's self - propelled with infinitely variable operations. It can be disassembled to fit through 600 mm access holes in storage tanks. The seal system allows for variable blast widths from 2' up to 20', useful for weld seam inspection or line removal. It's a modern, fast, and versatile solution for dust - free dry abrasive cleaning and texturing of horizontal or slightly inclined surfaces, eliminating the mess of hand blasting. It creates an ideal surface for coatings and overlays while containing abrasives and debris to prevent hazards and pollution. With a 508mm (20') working width, it can quickly blast steel to SA 2.5 - 3 standards, as well as concrete and asphalt easily. An optional seal system can change the blast width. The blast unit is made of manganese steel. The dust collector has an integral compressor and a reverse air jet pulsation system for continuous operation. The drive wheels are within the blast cabinet width. The blasting width can be adjusted for line removal and weld inspection. The self - propelled variable - speed drive gives operators full control. A grill in the lower separator hopper prevents foreign objects from damaging the blast wheel. It can use up to S780 abrasive, and the blast wheel can rotate in both directions (optional). Bartell Global offers other models like SPE 9ES, SPE 9G, SPE 12ES, and SPE 16ES in addition to the SPE 20ES.
Using the SPE 20ES shot blaster is straightforward. First, make sure it's properly disassembled and reassembled if you've passed it through a small access hole. Power it on and adjust the speed using the self - propelled variable - speed drive according to your needs. You can vary the blast width with the optional seal system. For different tasks like removing old coatings or inspecting welds, set the appropriate width. When it comes to maintenance, regularly check the dust collector. The integral compressor and reverse air jet pulsation system help it work continuously, but clean it to ensure good performance. Also, inspect the grill in the lower separator hopper and remove any foreign objects. Check the blast wheel for wear and tear, especially if you're using abrasive materials. If you choose the optional feature, make sure the blast wheel rotates smoothly in both directions. Keep in mind that it's designed for specific surfaces like concrete, steel, and asphalt, so don't use it on inappropriate materials. And always follow safety procedures to avoid any hazards and protect the environment.
