Air gap DN32/40/50 with thermal insulation housing, odour-proof HL904

Sewer ventilation device – effective protection against odors

This air vent, designed for installation with individual sanitary appliances, is a reliable solution to the problem of unpleasant odors from the sewer system. Particularly useful in situations where the drain level is more than 4 meters away from the sewer riser. Its operation is based on equalizing the pressure in the installation, preventing water from being sucked out of the traps and, consequently, preventing unwanted odors from entering the rooms.

The HL904 air vent is universal and can be used in various places – under a sink, washbasin, bathtub or shower tray. Thanks to its design with easy installation in mind, it will work both in new installations and during the modernization of existing ones. It is worth noting that its construction allows for effective operation even in difficult temperature conditions – from -20°C to +60°C.

Features and benefits

• High efficiency: air flow rate of 5.5 l/s ensures effective ventilation and prevents the formation of negative pressure in the installation.
