General information
Features and applications
The SFX. breather caps are made with a special internal geometry (Elesa patent) that prevents the leakage of fluids through a linear labyrinth (splash guard effect) and promotes condensation of the outgoing vapours.
The external snap-on anti-splash semi-discs (execution+P) located at the mouth of the threaded fitting hole, are made up of fins offset from each other so as to constitute an additional labyrinth in the most critical cases of strong fluid projections.
Technical data
Air flow rate for each model can be determined from the graph here below by calculating the difference between the pressure inside and outside the reservoir.
