DWL | Dynamic Weather Louver
The DWL Exterior Dynamic Weather Louver complements the SHX-UN universal pressure relief vents offering superior wind and weather protection without restricting the internal vents Free Vent Area (FVA). The DWL provides about twice the free vent area of fixed vane weather louvers used as standard within the HVAC market. Accordingly, specifying DWL can halve the number of units needed to deliver the required performance.
Our Dynamic Weather Louvers offer 98% wind seal, improved sound reduction and improved thermal rating compared to fixed louvers. Their performance is facilitated by thin but robust powder coated steel louver blades. The blades achieve up to 99% closing and offer protection from storm-blown rain, with reduced draft based heat loss from the building.
DWL Louvers, like all AmVentco products, have been thoroughly tested in the test blast simulator. During testing, in conjunction with SHX-UN units, the louvers were found to increase back pressure by only 10% during a gas suppression or simulated GIS discharge. Because the AmVentco range of vents operates well below the projected peak pressure as calculated by the Vent Design Coefficient (vDc), this combination is still the most efficient pressure/blast relief product on the market.
Guaranteed quality with acceptance in many locations worldwide.
