What is an Inline/Oblique Duct Blower?

An inline blower is a fan that sits in line with the ductwork. It’s a cylindrical fan with an impeller that pushes air straight through the duct. These fans are used to either exhaust air from a space or to pull air through a system with a long duct run or multiple bends, which would cause a loss of air pressure.

An oblique blower (also known as a mixed-flow fan) combines the best characteristics of both axial and centrifugal fans. The impeller of an oblique fan is set at an angle to the airflow, which allows it to generate higher static pressure than a traditional axial fan, while still maintaining the compact, inline design. This makes them highly efficient and effective in applications that require a balance of high airflow and resistance to static pressure.

Key Features and Benefits

• Quiet Operation: Because these fans are installed inside the ductwork, often in attics or crawl spaces, they are significantly quieter than wall-mounted or ceiling-mounted fans. The ducting itself helps to dampen the noise.
• Space-Saving Design: Their compact, cylindrical shape allows them to be discreetly installed in tight spaces, leaving rooms free of bulky equipment.
• Superior Airflow: Unlike simple duct boosters, these fans are powerful enough to move large volumes of air over long distances, making them ideal for complex ventilation systems.
• Versatile Applications: They can be used for both supply (bringing in fresh air) and exhaust (removing stale air), making them highly versatile.

Common Applications

• Residential HVAC: Used to boost airflow to rooms at the end of long duct runs, ensuring even heating and cooling throughout a house.
• Bathroom and Kitchen Exhaust: Ideal for removing moisture, smoke, and odors from these areas. By placing the fan in a remote location, the noise is greatly reduced.
• Grow Rooms and Hydroponics: Essential for creating a controlled environment by ensuring a constant flow of fresh air, managing humidity, and removing heat.
• Server Rooms: Used to circulate and exhaust hot air generated by computer equipment, preventing overheating.
• Commercial Buildings: Perfect for ventilating offices, restaurants, and other commercial spaces that require quiet and efficient air circulation.
