General information

Features and applications

The SFX+a 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 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.

Other executions

Special executions on request

Neutral cap without symbols.

Cap in RAL 3000 red colour.

Threaded fitting also with American conical gas threading NPT - ANSI-ASME B1-20 for the descriptions marked in the table with #.
