Actual installed airflow depends on the equipment's airflow resistance.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum static pressure?\u003c\/strong\u003e\u003cbr\u003eThe maximum static pressure is 0.790 inH₂O (20.09 mmH₂O), approximately 196.8 Pa. Maximum pressure occurs at zero airflow rather than simultaneously with maximum free-air flow.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the noise rating and bearing type?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer lists 37.5 dB(A) acoustical noise and a ball bearing system.
