High Pressure Blowers

High Pressure Blowers, aka forced draft high-pressure fans, are the go-to design for continuous duty industrial applications with high static pressure and low airflow. They can move clean air, light particulate, or vapor, and can be customized to handle abrasive, sticky, and hot airstreams.

AirPro designs and constructs custom heavy-duty, durable High Pressure Blowers using fully welded material, which provides a higher quality product compared to riveted construction. There are multiple options for materials of construction, including fiberglass, for various thermal, corrosive, particle-laden processes, and environmental conditions.

Types of High Pressure Blowers

High Pressure Blower wheels have straight radial blades (positioned at 90-degree angles to the outside surface of the wheel hub) to keep them free of debris as the air and materials flow through the airstream.

Our High Pressure Blowers include two primary wheel types – Open and Shrouded. Surgeless design enables them to provide consistent performance through variable flow (low to medium) and uniform pressure. The most appropriate wheel design is based on the volume and pressure combination of the air, along with the desired operating efficiency of the blower.

In addition to four pre-engineered models, our High Pressure Blower line includes two hyper-custom models with several base designs. Capable of handling low particulate or vapor in high-pressure applications, our highly Custom High Pressure Blowers:

  • Meet unique customer requirements, space limitations, and equipment footprints to achieve API 673/560 requirements.
  • Serve the widest range of applications, larger fans, and higher horsepower (1.5 – 1500 HP range) motors even when fixed speed is required.
  • Accommodate consistent wheel width and optimize for low volume with greater efficiency at peak performance.
  • Carry our industry-leading 3-Year Gold Standard Warranty (like all AirPro products). Precise, rugged and reliable, we build these fans to last.
  • They also allow for a vast array of customization options, including:
    →Gas-Tight Fans
    →High-Temperature Fans
    →Special Alloys/Abrasion & Corrosion-Resistant Materials
    →Insulated Housing & Other Thermal Controls
    →Special Coatings & Finishes
    →Unique Sound Requirements
    →Unique Space Requirements
    →Skidded Process System

High Pressure Fan Performance & Design Specs

Product Description: Open High-Pressure Blower:

HPRL – blower designed with an open radial wheel. Engineered for low air volumes at high static pressures. The open radial wheel does involve decreased operating efficiency when compared to the shrouded wheel but covers a wider range of air volume and pressure combinations.

HPRM – high pressure blower similar to the HPRL but with a wider wheel design. The increased wheel width increases the air volume capacity, which increases the efficiency of the high-pressure blowers.

HP#R (*Design Number appropriate to the application) – highly custom blower able to meet far more points on the fan performance curve for higher efficiency at peak. Engineered to the Nth degree based on your specific application requirements, these designs also solve for fixed speed requirements.

Product Description: Shrouded High-Pressure Blower:

HPSL – blower featuring a shrouded wheel design. This wheel type is designed to move low volumes of air at high static pressures with high operating efficiencies.

HPSM – blower also featuring the shrouded wheel design. With increased wheel width, this model is designed for low-to-medium air volumes at high pressures.

HP#S (*Design Number appropriate to the application) – highly custom shrouded blower able to meet far more points on the fan performance curve for higher efficiency at peak. Engineered to the Nth degree based on your specific application requirements, these designs also solve for fixed speed requirements.
