This 5 inch 13kW STADIUM Stadium anti-draft vent has a built in anti draught baffle which is designed to reduce or stop wind blowing through the vent by its unique duct design. Install the Stadium anti-draft vent with a 127mm (5″) core drill. Unlike some other core drill air vents an extension tube is supplied with this core drill ventilator for walls over 9 inches up to a maximum of 23 inches. The Stadium BM725 anti-draft vent should be installed as close to the appliance as possible and should be fitted as high up as possible. This ensures the cold air being drawn in mixes with the warm air at the top of the room. This creates a negative pressure, which theoretically draws fresh air evenly into the property through the envelope of the building.However, MVHR systems are not suitable for all new homes. The more airtight the house, the more effective the MVHR system will be, and it is generally accepted that 3m³/hr/m² level is necessary to see real benefits. Thus, your new home needs to be suitably airtight to ensure a MVHR system will work efficiently.

BM418B stadium core vent brown outer cowl and brown internal grille 5″ 71K, complete with anti draught baffle. This anti draught air vent is used for Domestic heating boilers and decorative fuel effect fires – Vario 100 Whole house mechanical ventilation with heat recovery (MVHR) has become the ventilation ‘must-have’ for self build projects. (That said, such systems are not suitable for all new homes — more on which later.) If there is no wind then the home may not be ventilated, and conversely if the wind is blowing hard then the home could be over ventilatedThe extract fan extracts the stale, humid air from the wet rooms (bathrooms, kitchen, utility, etc). This stale air is then passed over a heat exchange matrix – where heat is ‘recovered’– before it is discharged outside the house The kit includes a cowl vent for exterior use, a louvre grille for inside, a 350mm length of pipe duct and an optional anti-draught baffle. This baffle reduces the airflow and also the feel of a draught through the vent. The vent can easily be fitted in both refurbishment and new build situations with the use of a 5" (127mm) diameter core drill.

Samdo Sintered Vents provide an innovative way to decrease molding defects while improving venting efficiency.

Product Question + Answer

Sintered Vents provide an innovative way to decrease molding defects while improving venting efficiency. Applications MVHR systems are also best designed in and installed from the outset, due to their ductwork. Thus such systems can be difficult (but not impossible) to retrofit into existing properties. A positive input ventilation system introduces fresh air to the home from a unit placed in loft space. This system is Nuaire’s Drimaster (Image credit: Nuaire)

Smith & Richardson offers the widest range of popular core box vents. Most are available in US and Metric sizes. Brass – Slotted Core Vents These are still significant savings when compared with MVHR systems, especially in homes where the heat recovery element would not be effective and ductwork would simply not be practical to install. Passive Ventilation Adjustable Airflow: With a 100cm² squared free area (adjustable to 70cm² with the supplied anti-draft baffle), the Stadium Core Vent ensures efficient air circulation for up to 21kW input, enhancing heating efficiency.

Samdo Sintered vents are inserted into molding dies to assure sound castings. They allow the escape of gas and prevent the passage of smelt. Acoustic lining reduces sound by 44 dB with internal panel fully open and 50 dB when closed (Dn,e,w). Another solution, which needs designing in from the start, is passive ventilation.
