A bug blower, also known as a drilling rig fan or marine bug blower, is a heavy-duty industrial fan designed for use in hazardous environments, particularly on oil and gas rigs (both onshore and offshore). Its primary purpose is to: Disperse insects: Its powerful airflow keeps flying insects away from workers and equipment. Ventilate: It helps to clear hazardous gases that can accumulate in drilling areas. Cool: The strong air movement provides a cooling effect for the rig crew in hot environments. These blowers are built with safety in mind, featuring explosion-proof motors, non-sparking blades, and sturdy construction to withstand the demanding conditions of industrial sites.
