Donaldson Coolant Filters


Cooling systems are typically partial flow (by-pass) filters, with less than 10% of coolant flowing through the filter. We offer a range of filters designed to work in a variety of operating enviroments and maintenance schedules. Use of the correct filter is important to maintain the proper balance to prevent over-concentration (silicate dropout) or under-concentration, which leads to corrosion, liner pitting and other system problems.


Coolant Filters

There are 3 types of standard coolant filters.

  1. The pre-charge filter, which contains enough coolant additive to initially charge the cooling system and to allow for depletion to the first service interval.
  2. The standard charge spin-on filters which contain adequate chemical additive to maintain cooling systems between service intervals.
  3. Blank filters which contain no chemical additve and can be used with cooling systems maintained by liquid additive, systems using long-life coolants which require no additive, or on overcharged systems to help bring te additive back to the normal range.  Blank filters are not intended for use with water-only systems.
