Operating principles

BAMVENT-50 is an innovati and effective solution when it is not possible to reach the drainage column or if you want to avoid invasive interventions. Inside the valve cover there are 2 membranes that let the air in into the drainage system only in the presence of depressive effects generated during the evacuation of waste. Once the depressive effect has ceased, the membranes return to their rest position without any mechanical support, effectively closing the access or escape of air. The ventilation unit has a capacity of 7.5 liters of air per second and, once installed, does not require maintenance.

Application scope

ABS device for the ventilation of the wastewater discharge system compliant with EN 12380 and suitable as required by the UNI 12056-2: 2001 standard for systems in residential, industrial and commercial, public and receptive buildings such as hospitals, retirement homes and RSA, hotels, schools, places of worship. The BAMVENT-50 ventilation valve can be installed inside the building in a whole series of application situations: inside a technical shaft, in the false ceiling, under a sink, under a bidet or inside a cover casing bathtub or shower box, in the masonry with a special built-in box equipped with a grid for the air intake.

Design instructions

The BAMVENT-50 aid admission valve follows the design prescriptions as per reference standard UNI EN 12056-2: 2001. Due to the flow capacity determined by the project, the BAMVENT-50 valve ensures a maximum flow rate of 7.5 liters / second of air.

Installation method

Equipped with a special clamp, the BAMVENT-50 valve can only be mounted in a vertical position on pipes with a diameter of 32-40-50-63 mm. It is advisable to always provide a possibility of access to the device for any inspection needs, despite the fact that the product does not require maintenance.
