Aeration / deaeration plant L252

Aeration/deaeration plant, max. throughput 300 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.

Louvre, attack-proof, pre-finished, rigid design, with a stable frame, slats and 1 x 1 mm insect screen. The insect screen serves as first filter stage and prevents the ingress of small animals, insects and organic coarse material.

Air line in partial lengths according to the specific local conditions, with a connecting plate designed to suit the louvre (item 1.0) for air-tight bolted fixing to the interior structure wall, with pipe connection piece.

Cylindrical air filter unit L252, with connection pieces on both sides, suitable for the air line, with filter for suspended matter H13, with central 1/2“ condensate drain and ball valve for connection to the customer’s drain pipe. The cylindrical air filter unit is designed for installation directly into the air line. The air filter unit houses a filter for suspended matter that achieves a separation degree of up to 99.99% in accordance with DIN EN 1822 for optimal supply air purification.

Safety valve type 170-1 as an additional overpressure/underpressure protection for the structure in case of malfunctions. The reaction pressure is 1000 Pa.

FAQ

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.
