AB-002 Vent Filtration

Tanks commonly store various liquids and require vent filters to prevent damage from pressure changes. Factors affecting vent filter life include environmental conditions and operating temperatures. Proper system sizing is crucial to prevent tank collapse. Key factors for sizing include tank vacuum, desired air flow rate, filter media flow rate, and system temperature. Hydrophobic filters like PTFE membranes are recommended for tank venting. To determine the number of cartridges needed for a vent filter housing, follow these steps: identify cartridge type and micron rating, determine air flow rate, consider operating temperature, and establish maximum vacuum allowed in the tank.
