Features and applications
Suitable for use when it is necessary to avoid the loss of the cap.
The elastic ring, housed in the special groove of the cap, can rotate freely.
The spiral ring connects the elastic retaining ring to the chain.
SFP-LP 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.
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.
