Metal mesh prefilters, on the DD-MINI, offer critical spark arrestance protection when welding, grinding, or any working application that can produce sparks.
The DD-MINI can be fitted with up to two metal mesh prefilters. One is installed horizontally, just below the steel grate. The uniform mesh material restricts flow just enough to increase face velocity (FPM) by up to 20%.
An optional 2nd stage metal mesh can be installed vertically in the filter compartment, adding an extra layer of spark protection. The DD-MINI filter compartment allows a total of 4-inches of filter media, often featuring one metal mesh prefilter, and a 2″ paper pleat filter.
« As a repeat customer, and owner of both wet and dry downdraft tables, we cannot say enough about the products, and the people at Diversitech…….both are a pleasure to work with! »
« The tables are now fully functioning! The students were on them yesterday, and the instructors were so impressed. One instructor even said that he’s “old school” and wasn’t sure about the downdrafts, but he was very impressed. »
« We love the downdraft table and are using it full time. We will probably be looking for another one in 6 months to a year as well. Thanks for a nice product. »
