Fluid velocity should be less than 3 m/sec for GM filters. SS or GM usually preferred for distilled water.
CI & CS OV filters, scf and WB dual filters can be used, but corrosion will occur. Increased corrosion
rates in sea water. See Note 1 & 2. EP seals preferred above 100°C.

EP 'O' rings preferred. The copper based alloys in WB and GM filters may act as biocides. CI (for OV only)
and WB filters will corrode in water base solutions. See Note 1 & 2. SS usually preferred.

Do not use OW filters. Use monel elements. Some attack may be expected at high temperatures.
Zinc Sulphate
ZnSO4

Some attack possible at high temperatures. CI or CS could be considered for 'room' temperature
applications. See notes 1 & 2. Cautious use of dual filters. Special cocks required in SS dual filters.
