Air vent with thermal insulation housing and protective mesh for quick cleaning (includes DN32/40/50 reduction) HL903

Protection against unpleasant odours and optimal ventilation

This air vent with a thermal insulation housing is a reliable solution for ensuring proper ventilation of the sewage system. It prevents siphons from being drained, eliminating unwanted odours in rooms. It is particularly useful for long, horizontal sections of the sewage system – over 4 meters – where this problem occurs most frequently.

The air vent is designed for mounting on individual sanitary appliances and sewage connections. The set includes a DN32/40/50 reducer, which makes it easy to adapt to different pipe diameters and ensures versatility of application.

Performance and durability in all conditions

The design of the air vent guarantees a high airflow – up to 8 liters per second – which ensures effective ventilation and minimizes the risk of drainage problems. Made of high-quality materials (ABS/PP), it is resistant to mechanical damage and corrosion, and its A1 class confirms the high quality of workmanship. The device maintains full functionality in a wide temperature range, from -20°C to +60°C, making it an ideal choice for both indoor and outdoor installations (provided adequate protection against the elements).

Additionally, the protective mesh minimizes the risk of contamination inside the device, and the thermal insulation housing reduces moisture condensation, which translates into a longer service life and trouble-free operation. Compliance with EN12380-A1 standard confirms the safety and reliability of the device.
