CO2 trap including Vent Filter

CO2 trap with integrated vent filter is an external installation kit for the sterile ventilation of pure-water storage tanks. The adsorption vessel combines a vent filter for sterile air intake with a 10'' filter cartridge rated at 0,2 µm. Hydrated lime contained in the cartridge binds CO2 from incoming ambient air, helping prevent quality loss of the stored permeate that would otherwise result from carbon dioxide uptake. Saturation of the cartridge is indicated by a bluish discoloration, so filter condition can be checked at regular intervals and the element replaced when exhausted. Supplied as a single piece for storage-tank accessories from manufacturer Evoqua Water Technologies, the kit is intended for external mounting on laboratory tank systems. By retaining CO2 while allowing controlled sterile venting, the unit supports stable conductivity and purity of stored purified water during level changes. Suitable for pure-water storage installations where external CO2 protection and sterile tank breathing are required as part of routine tank hygiene.
