High Pressure Blowers
Delivering air at pressure takes a high pressure blower. These centrifugal fans are the right choice for applications involving cooling, drying, filtration, powder conveying, combustion processes, and long runs of ducting.
Paul’s Fans builds and supplies high pressure blower fans to industries ranging from petrochemicals to paper and pulp. With delivery available throughout North America, each one is engineered for durability and backed by our service and support organization.
High Pressure Blower Fan Design
Blower fans use a centrifugal design to create air movement. The heart of a blower looks like a water wheel but is driven through the axle by a motor or engine. Air enters through the center in a direction parallel to the axle and wheel rotation throws it out with the housing directing it into the attached ductwork. In contrast, axial fans use an aerofoil section that creates lift.
Blower fans take one of two designs: radial or squirrel cage, sometimes called barrel. Radial blower fans move air using a water wheel-style impeller. In squirrel cage blower fans the impeller is wider and more like the wheel of a sternwheeler riverboat.
Wheels used in high pressure blowers take several forms such as backward inclined and curved. For optimal performance, match the wheel to the application. Specialists at Paul’s Fan Company can advise on the appropriate design for your air handling needs.
Blower Fan Strengths
These types of fans are energy-efficient when compared with axial fans. They run quietly, require little maintenance, and hold up well to air containing moisture and particulates. Their primary strength is in delivering high pressure air in a specific direction. They are not a fan for moving high volumes of air over a wide area.
Application for High Pressure Blowers
Centrifugal fans / high pressure blowers are the right choice for systems with long duct runs and where the air is needed at a very specific place rather than over a general area. They’re also good for conveying materials.
- Powder transport (powders, granules, fibers)
- Combustion applications – for example, flue gas recirculation
- Room pressurization (clean rooms, metrology rooms)
- Dust collection systems (when installed on the clean side of the filter)
- Directed cooling – portable units are often used to lower the temperature of a control panel or motor
- Drying (accelerating evaporation)
Special Features to Consider
Paul’s Fan Company will design and build a high pressure blower fan to meet the particular needs of your application. Six aspects to consider in addition to wheel type and size are:
- Airflow and pressure required (CFM and SPWG)
- Operating temperature range – blowers for hot air may need special components, materials, and tolerances
- Explosion-proof environments
- Housing material – especially when the air could contain grit or dirt
- Direct or belt drive
- Electrically or engine-driven
Why Choose Paul’s Fan Company?
Buying from a catalog will never give you the air-handling performance you need.
At Paul’s Fan Company we take the time to understand your application before proposing a solution. Only when the requirements are defined and agreed will we put our decades of fan experience to work in designing and building the fan you need. We’ve learned this is the only way to ensure you get a fan that meets your performance and reliability goals.
To help you get your fan running in the least time possible we offer a turn-key installation service. This includes any necessary ductwork. After installation, because industrial fans are expected to perform in challenging environments, we provide 24/7 support and complete maintenance service.
If you’re looking for a custom high pressure blower fan, Paul’s Fans provides the products and service you need.
