If your priority is maximum airflow and long blower life, and you're comfortable with frequent replacement, this is the rating that loads your system the least.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNominal size: 28-1\/2 x 17-1\/2 x 1″\u003c\/li\u003e\n
