Royal Dahlman Pulse Jet Gas Filters

Date: 02-12-2019

One of the filtration technologies used by Royal Dahlman for the filtration of industrial gases and waste streams is the automatic blow-back pulse jet cleaning technology. One of the major key factors in design optimisation is the selection of the right filter material. One of these is the sinter fibre mesh. Manufactured from randomly laid metal fibres, sinter-bonded to form a uniform high porosity filter medium, RD-F metal fibre demonstrates a significantly low pressure drop, high permeability and excellent dirt holding capacity. Sintered metal fibre may be pleated to increase the available filtration area of a filter cartridge, thereby further increasing dirt holding capacity and so minimising maintenance and maximising on-stream processing. With the feasibility to formulate metal fibres to meet specific application requirements combined with inherent durability, sintered metal fibre filters can be cleaned in-situ without interrupting process flow thereby providing the ultimate in process economics by reducing downtime to a minimum.
