The SH 3660 from Viking Blast & Wash Systems is a larger, redesigned unit with a 36-inch-wide x 60-inch-tall blast zone. The 3660 eliminates the need for a lower screw auger, reducing wear while improving efficiency. The air intake is very aggressive and allows for application of more than 2,500 cfm, yielding cleaner abrasive and a cleaner cabinet. The drum is made of manganese and is lined with 0.5-inch-thick cast chrome/moly liners, giving the highest degree of wear resistance. Most applications are covered by the standard offering, but the system can also be fitted with a rotary scalping drum and auxiliary abrasive hoppers as well as 20-hp, 25-hp or 30-hp blast wheels versus the standard 15 hp. Viking uses safety light curtains as standard with two palm buttons yielding the highest level of safety offered in the market. All Viking cartridge-style dust collectors are sold with NFPA-required deflagration panels as standard.
