ENARDO Model 2000
Emergency Relief Vent – Pressure Relief Only

Applications

ENARDO’s Model 2000 Emergency Relief Vent provides an emergency pressure relief opening for storage tanks when exposed to overpressures not handled by standard tank vents. When properly sized, this vent provides the capacity to meet API Standard 2000, NFPA 30 and OSHA (29 CFR 1910.106) for emergency venting due to fire exposure. The Model 2000 provides pressure relief only. For an emergency relief vent with vacuum, see ENARDO’s Model 2500.

ENARDO’s Emergency Pressure Relief Vents are designed with a hinged cover that begins to open at the predetermined setting and relieves excess pressure. When the overpressure dissipates, the cover reseals tightly onto the base. The hinge mechanism prevents misalignment and provides an accurate reseat.
