EXP | Expander Box Weather Louver
The EXP Expanded Weather Louver unit is used with AmVentco’s DUX range of pressure relief vents in halocarbon installations. It has been specifically designed to provide a Free Vent Area (FVA) matching that of the DUX while providing the weather protection essential for two-way vents in exterior walls.
The weather sealing must be maintained while supporting two-directional flow, a sealed external unit cannot be used, making an open louver design essential.
The louver blades are assembled into a custom-designed ‘Expander Box’ – hence EXP – which increases the effective FVA to match the 85% FVA of the DUX. The result is a fixed blade louver larger than the internal vent, offering no restriction and adding zero to the Vent Dynamic Coefficient (vDc). (Other fixed louvers on the market typically provide at most only 50% FVA)
