Donaldson Blue® Coolant Filters

Donaldson Blue® coolant filters are available in two different packaging options – additive replenishment technology or non-chemical (blank). They are direct replacements for standard coolant filters.

Donaldson Blue® Coolant Filters with Additive Replenishment Technology

Donaldson Blue coolant filters with Additive Replenishment Technology maintain cooling system balance through a controlled release of additives over a period of time to maintain proper additive levels. 

These premium coolant filters use Synteq™ media to remove fine contaminants from sensitive coolant systems. Donaldson Blue filters with additive replenishment technology will extend coolant maintenance intervals up to once a year or 195,000 km / 150,000 mi.

Features

• Direct replacement to standard OE filters – no system modifications or special maintenance required
• Heavy-duty Hydrogenated Nitrile Butadiene Rubber (HNBR) seals to withstand extreme cold and heat

Benefits

• Maintains healthy coolant condition through a controlled release of additives
• Reduces maintenance costs
• Extend traditional diesel engine coolant maintenance intervals up to once a year or 195,000 km / 150,000 mi

Applications

• Traditional coolant systems
• For use with Supplemental Coolant Additive (SCA & SCA+) – Ethyl Glycol or Propylene Glycol coolants

Available Media Type

• Donaldson exclusive Synteq™ – synthetic fiber media for greater filtration efficiency and higher dust-holding capacity

Non-Chemical Donaldson Blue® Coolant Filters 

Non-chemical Donaldson Blue filters will go the distance of your coolant. This allows you to add liquid additives to your cooling systems as needed.

Features

• Allows the user to add liquid additives to their cooling systems as needed

Benefits

• Will last the distance of the system's coolant

Applications

• Organic acid coolant systems – Organic acid technology (OAT)
• Hybrid coolant systems – blend of traditional and organic coolant 

Available Media Type

• Donaldson exclusive Synteq™ – synthetic fiber media for greater filtration efficiency and higher dust-holding capacity
