Protectoseal Series 16240 Side-Mounted Vacuum Relief Vent is intended for use where only vacuum relief is required. Specifically designed to be side mounted to the tank structure or piping. A pallet in the vent housing retards air intake as the tank normally breathes in due to atmospheric temperature changes or emptying of the tank. The pallet opens and closes to permit only that intake relief necessary to avoid tank damage under normal operating conditions. Series 6240 is offered for end-of-line applications.

• Certified flow curves validating flow characteristics of unit
• Certified test report verifying specified settings and leakage performance
• “Air-cushion” pallet design for low leakage performance of no more than 1 SCFH at 90% of the set pressure
• Pallet assembly guides and center pallet stem guide to ensure proper alignment of pallet assembly on the seat and smooth lifting and reseating action
• Automatic condensate drainage design to mitigate freezing, binding and clogging
• Swing-bolt design facilitating inspection and easy maintenance
• Serialized unit and associated weights for easy identification and traceability
