Data Sheet
GO Data Sheet Donaldson DBB8777

Donaldson spin-on elements enable fast, simple and clean servicing, without the requirement of specialised tooling, lifting devices or elevated work platforms. The filter media has greater protection from environmental contamination during service and installation than common cartridge-style elements, further enhancing Donaldson’s high initial efficiency.

Contaminant loaded media is disposed of with the replaceable can, eliminating the need for manual cleaning of fixed infrastructure or direct handling of concentrated contaminants.

The DBB8777 spin-on elements can be configured for high flow rates with minimal pressure drop.
