Specifications
& Notes
Westdale
wound cartridge filters offer depth filtration over a wide range
of particle removal ratings and have a high dirt holding capacity
by trapping dirt in the passageways.
The
advantage of this type of disposable filter cartridge is that it
offers high efficiency at low cost.

General
Notes:
Metal
cores extend beyond the temperature limitations of the fibres. The
temperature of the fluid to be filtered is very important with respect
to compatibility and it is advisable to carry out proving tests
on the cartridges with the liquid to be filtered if it is to be
used at elevated temperatures.
It
is advisable to select cartridges for the lowest possible initial
pressure drop in order to maximize the useful life of the filter,
2 psi (0.14 bar) being the norm.
If
a filter is selected for a pressure drop of 5 psi (0.35 bar) it
can be seen that 35% of the life of the filter will be lost.
