Dual capacity housings can serve as either basket strainers or bag filters. Covers are easily removed, without tools, and the basket or bag is quickly and easily cleaned or replaced. Low price, greater dirt holding capacity, and higher flow rates make the dual bag filter vessels a very cost-efficient choice! NPT or Flange styles. Available in size #1, #2, #3, or #4 or any other size upon request.
Duplex Basket Filter housing is generally used for separating coarse particles. It is use to retain particles of all sizes. Duplex Basket filter is constructed to have Inside to outside filtration capturing the particles inside the strainer element as well as outside to inside flow with considering the design parameters. The main parts of Duplex Basket filter are Filter Element, support ring, Internal perorated Element Support to assure prevent damage during high pressure drop across the filter during operation. The filtrate fluid can be collected at the outlet.
