The Cased Dalamatic (DLMC) is a stand alone collector with support legs and hopper. The inlet is at the top of the collector to drive dusty air down towards the hopper. This downward air pattern helps to keep dust pulsed off of the bags moving towards the hopper and therefore reduces dust re-entrainment on the bags. This makes the DLMC a popular choice for light and fluffy dust applications.
In contrast, the Dalamatic Insertable (DLMV) has no legs and hopper. The DLMV is used in applications such as bin venting where the collector is mounted on top of a bin or silo and the bags are often times actually inserted inside the top of the bin. As the bin or silo is being filled, dusty air is filtered by the DLMV with cleaned air exiting the collector. Once a dust cake forms on the outside of the bags, a pulse of compressed air inflates the bag and breaks the dust cake free of the bag depositing the material back into the bin or silo so no material is wasted.
Q. What Is a Hydro-Entanglement Process?
A. Instead of a mechanical process using needles to entangle and compress polyester fibers into a felt material, the hydro-entanglement process uses jets of water to entable and compree the polyester fibers into felt. The process creates a material that is more uniform and provides better filtration.
Q. How Are Dura-Life Bags Different from Standard Polyester Bags?
A. Dura-Life bags are made from polyester material that is created through a hydro-entanglement process instead of a needle punch process. The hydro-entanglement process creates a more consistent and uniform filter material. The material is comparable in thickness to standard polyester, but weighs about 1/3 less. The fibers are smaller and the hydro-entanglement process creates a loftier and lighter weight fabric that filters more effectively.
Watch why Donaldson Torit's Dura-Life filtration technology exceeds that of conventional polyester and other bag filters.These bags can offer twice the life of other bags, and are offered for all popular brands of collectors. Improved efficiency offers greater performance, and reduces maintenance and energy costs.
