A mushroom ship vent is a type of ventilation system used on marine vessels. It is characterized by its distinctive mushroom-shaped head, which is designed to be installed on the deck. This unique shape allows for efficient airflow while also preventing water, rain, and spray from entering the ship's interior. These vents are crucial for maintaining air quality, preventing moisture buildup, and reducing odors in various compartments, such as cabins, engine rooms, and cargo holds. They can be either fixed or adjustable, with some models featuring a built-in damper to control the amount of airflow

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.
