Did you know
- Protectoseal has been manufacturing tank safety products, including tank breather vents for controlled pressure and vacuum relief, since the 1930s, expanding from their initial flame arrester technology.
- Within Protectoseal's range of Pressure/Vacuum Relief Vents, the Series 8540H is an end-of-line conservation vent, offering both pressure and vacuum relief. It is a standard series variant, distinct from the 8540G, which is an 'Improved Performance' model designed for quicker pallet lift and higher flow at lower overpressures.
- The Protectoseal Series 8540H is chosen for its ability to provide both pressure and vacuum relief, maintaining the tank's vapor space within safe operating parameters while minimizing product loss due to evaporation. It features an 'air-cushioned' seating design for low leakage and automatic condensate drainage to prevent freezing and clogging.
