Function and Description
In- and Out-Breathing – for use with Aggressive Products
The E/KS vent cap allows vessels which are not pressurize to vent. The vent cap is made out of plastic and is the best solution in applications with aggressive media. This E/KS vent cap prevents rain and dirt from entering the vent line. The device is not flame transmission proof.
Protective Cover for Preventing Flame Transmission
It is often used in combination with Detonation Detonation Explosion, die sich mit Überschallgeschwindigkeit fortpflanzt, gekennzeichnet durch eine Stoßwelle. Flame Arresters, when those are used in vent lines, installed at a position which creates a long run up distance from the end of the vent line to prevent endurance burning. The E/KS vent cap will then be installed at the end of that vent line to prevent particles or rain from entering the line. The vent caps main components are a housing (1), a weather hood (2) and spacers (3).

Flow Capacity Chart
The flow capacity charts have been determined with a calibrated and TÜV certified flow capacity test rig. Volume flow V in (m³/h) and CFH refer to the standard reference conditions of air ISO 6358 (20°C, 1bar). For conversion to other densities and temperatures refer to Sec. 1: “Technical Fundamentals”.
