Yes, we can also offer you HUBER air filter plants with an integrated activated carbon filter. In addition, we offer the possibility of providing our systems for retrofitting an activated carbon filter.
Aeration / deaeration plant L661
Aeration/deaeration plant, max. throughput 3000 m³/h
Natural aeration/deaeration plant with air connections on both sides to improve the hygiene in drinking water
reservoirs.
Completely made of 1.4307 (AISI 304 L) stainless steel except the filter material, shielded arc welded, acid-treated in a pickling bath and passivated.
Security louvre, attack-proof, pre-finished, rigid design, with a stable frame, slats and 1 x 1 mm insect screen.
Air line in partial lengths according to the specific local conditions, with a connecting plate designed to suit the louvre for air-tight bolted fixing to the interior structure wall, with pipe connection piece.
Air filter unit L661 with connection pieces on both sides, suitable for the air line, with pre-filter and filter for suspended matter, with two DN 15/2” stainless steel condensate drains upstream and downstream of the filter package, each with ball valve, including wall mounting brackets.
The air filter unit is designed for installation directly into the air line. The pre-filter installed in the air line is filter class ISO ePM10 75% according to EN ISO 16890 and serves as second filter stage. The pre-filter is required to increase the lifetime of the subsequent suspended material filter as third filter stage. This filter is filter class H13 with a separation rate of at least 99.99% in compliance with DIN EN 1822.
Safety valve as an additional overpressure/underpressure protection to protect the structure in case of operating troubles. The response pressure is 1000 Pa.

Frequently Asked Questions
If there are no water level fluctuations in the drinking water reservoir and therefore no natural air exchange can take place, we can optionally work with a fan in the air duct. This ensures an optimal air exchange in the reservoir.
The air filters installed in HUBER aeration/deaeration plants comply with the current standards EN ISO 16890 and DIN EN 1822.
