Product Description
Product Overview
The XBF series multi-blade, low-noise kitchen exhaust centrifugal ventilators incorporate and adopt the design technology of the American "LAV" impeller. They feature the 11-62 and CF series multi-blade configurations, specifically addressing the challenge of oil buildup during kitchen exhaust applications—where conventional impellers are notoriously difficult to clean. Through focused research and continuous improvement, these fans are meticulously engineered and manufactured using advanced techniques and extensive industry experience.
