        Reloadable Pad Frames are
        ideal for use in reducing                                          •  Replace the filter core only
        filter costs where
      disposable panel filters are                                         •  Various media options
      normally used.  The FPF
      frames simply hold a pad
      of disposable media (either                                          •  Simple replenishment of core
      glass-fibre or synthetic) or
      washable media i.e.:                                                 •  Long life and robust construction
      reticulated polyurethane
      foam. The filter system                                              •  Can contain washable media
      removes the need to
      dispose of the whole filter                                          •  Economical
      when only the core
      element of the filter needs
      to be disposed of, thus                                              •  Made in Britain
      providing the most
      economic solutions in
      terms of storage, handling
      and disposal.
