L&J Technologies 94100 Vacuum Vent (High Pressure)

The L&J Technologies 94100 Vacuum Vent (High Pressure) is a Shand & Jurs storage tank vent designed to relieve vacuum conditions in liquid product storage tanks while withstanding internal stored-product pressure when the vent is not operating under vacuum conditions.

The 94100 vent is used in tank systems where pressure and vacuum control must be handled by the appropriate venting component without combining unsupported functions such as flame arresting, deflagration protection, emergency pressure relief, or detonation protection.

Process Controls Corporation - L&J Technologies 94100 Vacuum Vent (High Pressure)

This high-pressure vacuum vent supports applications where controlled vacuum relief is required as part of a broader tank protection equipment strategy.

Its design includes a balanced pallet for controlled lift and closure, along with a removable bolted cover that provides access for inspection and service. Available high-vacuum setting provisions allow the vent to be applied where elevated vacuum relief settings are required, based on system requirements and proper selection.

For industrial facilities evaluating vacuum relief vents, high-pressure tank vents, or Shand & Jurs tank protection equipment, the 94100 provides a dedicated vacuum vent option for liquid storage tank applications that require pressure resistance when closed and vacuum relief when operating.

Key Characteristics

High-pressure vacuum vent for liquid product storage tanks
Designed to relieve vacuum conditions while withstanding stored-product pressure when closed
Balanced pallet supports smooth lift and closure
Removable bolted cover provides access for inspection and maintenance
Available with provisions for high vacuum settings
Offered in 6″ and 10″ sizes
Flat face flange configuration to match ANSI 150 lb connection requirements
Dedicated vacuum relief function; not a flame arrester, emergency vent, deflagration arrester, or detonation arrester

Ideal Applications

Liquid product storage tanks requiring vacuum relief
Tank systems where the vent must withstand internal pressure when not relieving vacuum
High-pressure storage tank venting applications requiring a dedicated vacuum vent
Industrial tank protection equipment installations requiring access for inspection and service
Applications where vacuum relief must remain technically distinct from flame arresting or emergency pressure relief functions
