Dust Collectors - HE Model: HEF
Model HEF

Operation

The Murphy Model H.E.F. dust collector features, our cyclonic action inlet high in the filtration area complete with unique internal primary baffling. This forces the dust laden air to move in a downward spiral motion throughout the collector thus using the law of gravity to our very best advantage. This minimizes the dust loading of the filter tubes themselves.

Model HEF: Designed in circular modules giving unlimited capacities, and is automatically cleaned by reversing air flow for continuous cleaning. Suitable where compressed air is not available. For very high dust loads.

Features:

  • Completely automatic continuous self-cleaning.

    The automatic continuous cleaning which regularly loosens and allows the excess dust cake, which has formed on the outside of the dust tube, to fall away thus maintaining a rated filtration efficiency by weight at over 99.9% as small as 1 micron. (Higher efficiencies available upon request.) This effective filtration allows cleaned air to be recirculated within the plant (when allowable). The savings on heating and air-conditioning costs would be substantial.

  • Painted, heavy gauge galvanized construction.

    The HEF Model has a heavy gauge galvanized, all welded construction, painted a standard colour finish coat (other colours available on request). Unit is pre-assembled at factory to enable quick on-site installation by others. It requires only a properly sized foundation or pad and a crane to set the dust collector in place. (Optional: knockdown designs available. Please check with factory).

  • Flexible and simple design with clean side filter tube removal.

    The flexible and simple designs enable you to choose from several models without sacrificing efficiency. A few sizing considerations are the cfm, the air-to-cloth ratio, on-site location, the type of dust and dust loadings to be filtered. Some of the available types of material discharges are hopper storage, continuous rotary air lock discharge, and screw conveyor discharge, all depending on the desired requirements of the particular application.

    Top filter tube removal allows you clean and easy access. You will find this a very simplistic method of filter removal and installation. We use a positive seal friction fit connection for the filter tubes and cages. No tools are required. This allows maintenance, if required, to be completed in minutes rather than hours.

  • Numerous filter medias available.
  • Rugged weatherproof construction.
  • Flexible air-to-cloth ratios.
  • Either pull-through of blow-through operation.
  • Can be used as primary or secondary filter.
  • Booster fans available when used as secondary filter.
  • Optional equipment.

Options:

  • All sizes of fan packs c/w motors ranging from 500 cfm to 50,000 cfm and beyond, matched to filter requirements (fan packs can be factory mounted onto dust collector or supplied separate).
  • Explosion venting.
  • Silencer packages.
  • Several styles and types of discharges.
  • Inlet sizes available in 1" increments in round, square or rectangular configuration.
  • All sizes of rotary air locks and adaptors.
  • External walkways and ladders.
  • All sizes of screw conveyors.
