ER100 Emergency Pressure Relief Vent is designed to provide an emergency pressure relief opening for storage tanks when exposed to over pressures that are not handled by standard tank vents. These vents provide the capacity to meet API standard 2000 for emergency venting due to fire exposure when properly sized. These covers also provide quick easy access for tank inspection and maintenance.

The emergency pressure relief vent provides pressure relief only. Vacuum relief must be supplied by normal venting devices or ER200 emergency relief vent with vacuum.

When excessive pressure builds within the storage tank , the ER100 Emergency Pressure Relief Vent hinged cover begins to open at the predetermined set pressure, relieving excess pressure. When the over pressure has dissipated the cover reseats onto the base. The hinge mechanism prevents misalignment and provides an accurate reseat.
