- CSA approved "newly invented" snow proof Type B box style static roof EXHAUST vent (50 sq. inch flow) for use on sloped roofs when vents are installed near the peak of the roof (see local building codes)..
- Independently tested to prevent 99.99% particle infiltration during severe storm conditions..
- Micro pore stainless steel "no clog" permanent air filter blocks all unwanted elements (rain, blowing snow, sparks) while still allowing for air flow. The porcelain smooth filter holes self-clean 24 hours a day as air flows through the vent..
- Wider flange makes installation a snap and helps improve the overall seal..
- Arched design of the cap and neck allows melting snow and rain to flow around the vent..
