سلسلة SBV 603 فتحات تهوية ثابتة مائلة للخلف، عبوة من 6 قطع

These vents really move the air—my attic felt noticeably cooler the same afternoon I finished installing them. The 51 square inches of net free area per vent makes a big difference compared to the smaller ones I had before.

Installed these in my attic last weekend and the airflow difference is already noticeable. The 51 square inches of net free area per vent really moves the hot air out fast.

These vents feel much more solid than the cheap plastic ones I've pulled out before, that heavy-duty galvanized construction is noticeable. Was able to install all six in an afternoon to get better airflow through the attic.
