EH/0S

Vent Cap, End-of-Line

Function and Description

The PROTEGO® EH/0S vent cap allows vessels which are not pressurized to vent. This device prevents rain and dirt entering the vent line. The PROTEGO® EH/0S vent cap is not flame transmission proof. It is often used in combination with Detonation flame arresters, when those are used in ventlines, installed at a position which creates a long run up distance from the end of the vent line to prevent endurance burning. The PROTEGO® EH/0S will then be installed at the end of that vent line to prevent particles or rain from entering the line. The vent cap PROTEGO® EH/0S main components are a housing (1), a weather hood (2) and a protection screen (3). The device is equipped with a fixed weather hood out of metal. The protection screen prevents particles or rain from entering the line.

Features and Advantages

  • vent cap provides protection against environmental impact (harsh weather conditions, bird nests, etc.)
  • cost effective device
  • almost maintenance free
  • certified flow performance curves

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). Conversion to other densities and temperatures refer to Vol. 1: “Technical Fundamentals”.
