They would then lose vacuum, causing the boards to slip on the routing table, resulting in elevated product rejections and down-time. The customer told us it was difficult to know when to change the clogged filter element because there was no indicator or way to actually see the element through a metal housing. We first came up with the ST Spinner Series, which has an aluminum head connected with a transparent polycarbonate plastic bowl. The ST Series now allows operators to visually inspect the filter for clogging before they begin operating the router table. Solberg invested in proprietary molds to manufacture the transparent housings and the response has been fantastic! . filtration prolongs equipment life in high dust and dirt environments” “Intake What food processing applications do you see? Most of these applications involve pneumatic conveying or vacuum packaging. In both instances we have a variety of products available for this market. The BBF and 2G products discussed earlier are very common in pneumatic conveying of corn, grain and their processed variants. We also provide the liquid knockout systems for many meat-packing operations where keeping fluids and liquids out of pumps is crucial. We had an interesting application in a pasta manufacturing plant where flour was getting into a heat exchanger used to remove moisture from the process. The flour was clogging the equipment and needed to be removed from the air stream. The filter they had in line was working but was clogging too quickly, so we developed a system that sent a blast of compressed air back through the filter and knocked the flour build up or “cake layer” off of the pleats thus extending the maintenance interval for the filter. The product is called an RST (Reverse-Pulse See Through) and can be operated manually or the system can be automated using a differential pressure switch or a timer. Our mission is to partner with our customers to help them innovate and discover new possibilities. As you can see, we really enjoy taking on tough applications. Our customers can rely on Solberg’s years of experience to help them solve their customer’s problems. The RST Series See-Through Housing Thank you Solberg for your insights.
