General information

Features and applications

SFN. breather caps, owing to their high air flow rate, are particularly suitable for use on hydraulic power packs or tanks subject to rapid changes in liquid volume.

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.

Other executions

Special execution on request

Threaded connector also with NPT thread (National Taper Pipe Thread - ANSI-ASME B1-20) for the codes marked with # in the table.
