APPLICATIONS
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.
