General information
Features and applications
SFP-EX breather caps come complete with splash guard device (ELESA original design) that prevents oil loss and are particularly suitable for use where oil is violently agitated and could be splashed against breather cap. The correct positioning of the article in the design phase is essential to prevent accidental spills of liquid. In particularly heavy use conditions or very dusty environments the filters could progressively deteriorate, compromising the correct functioning of the article. Proper periodic maintenance is recommended.
Technical data
Air flow rate for each model can be determined from the graph calculating the difference between the pressure inside and outside the reservoir.
