AAV for Venting the Soil Stack and Avoiding Roof Penetrations

This advanced AAV protects the trap seals in the drainage system by allowing the intake of air, so a soil pipe can maintain the right level of pressure within the drainage system. The Maxi-Vent is used in the following types of drainage venting applications and is the universal solution for venting the soil stack in any building.

The Maxi-Vent eliminates roof penetrations and can be used with the Mini-Vent to vent an entire building without the need for passive vents pipes. It is resistant to extreme temperatures. Subject to being used with the insulating cap, Studor guarantees the performance of the Maxi-Vent from -40oC to +60oC, which far exceeds the requirement of EN12380 for the AI rating (which is “only” from -20oC).

Low Rise Buildings (3-4 Floors) Used on its Own

Building up to 10 floors: Used in conjunction with the Mini-Vent

The Mini-Vent is a solution for any single fixture and for a group of fixtures connected to a single branch, i.e. branch ventilation in residential/domestic and commercial applications. It can also be used with other Studor AAVs to complement larger and high rise building drainage systems and is ideal for all single fixtures: washing machines, toilets, sinks, baths and showers, etc.

This Mini-Vent advanced AAV protects the trap seals in the drainage system by allowing the intake of air, so that the right level of pressure within the drainage system is maintained.

The device is very easy to fit, and will decrease the amount of pipes needed within your drainage system installation. This patented and unique design can provide drainage solutions for bad odours and sewer smells in existing buildings (by retrofitting), plus it should be used when considering new builds and during the design of drainage systems.

Benefits of using the Mini-Vent include cost and time savings.

Above 10 floors: Used as part of the Studor System

The Simple Solution for Any Drainage System

Using a single pipe in conjunction with AAVs is always going to be more efficient than using two, or even three without giving any proper consideration of the functionality of the drainage ventilation! Utilising just a single pipe, the Studor System represents a complete and unique drainage and ventilation system solution for medium and high rise buildings. Compared to traditional systems that use 2 or even 3 pipes, in addition to providing a better functioning drainage system, the Studor System requires less space, reduced materials and less labour; resulting in medium and high rise buildings. Compared to traditional systems that use 2 or even 3 pipes, the Studor System requires less space, reduced materials and less labour; resulting in significant cost savings and helping to meet sustainability goals.

The Studor System provides greater protection, versus traditional methods, at the Point of Need against the unsteady state of drainage systems as it uniquely addresses both negative and positive pressures. Studor AAVs protect against negative pressures while the Studor P.A.P.A. handles positive pressures within the system. This innovative solution maintains a balanced state, keeping the pressure differential of the whole drainage system with the external environment below +/- 100Pa and will last the lifetime of the building.

Where there is a specific need to preserve the aesthetic design of a building, the specialist engineering capability of the Studor System allows the possibility for a totally sealed system with no external roof penetrations. Minimising roof penetrations reduces thermal heat loss and the requirement for working at height, while avoiding the risk of vent pipes being sited near air conditioning units.

Advantages

  • Reduces the need for fire stopping devices preventing the "chimney effect" in pipes, reducing the risk of fire spreading upwards between floors.
  • Provides greater freedom of design for engineers, architects and design professionals.
  • Protects the inner mechanism against the entrance of vermin, foreign objects and material by means of the specially designed screens.
  • Eliminates the risk of water leakages through unnecessary roof and surface penetrations.
  • Prevents transmission of odorous sewer gas into the building or surrounding areas
  • Is resistant to adverse weather conditions (-20oC to + 60oC).
  • Requires no maintenance, specially designed to resist extreme temperatures and deterioration.
  • Has a lifetime warranty - equivalent to that of the drainage system in which it is installed - repeated opening and closing will not affect its sealing operation.
