High pressure fans, also known as high pressure blowers, are the gold standard for industrial, continuous duty, high static pressure, low airflow applications. They can move clean air, light particles or steam, and can be adjusted to handle hot, sticky, abrasive airflows. We design and build tough, durable, high-pressure blowers from all-welded material, which compared to riveted construction provides a higher quality product. There are different construction material options, including fiberglass, for various thermal, corrosive, particulate-laden processes and environmental conditions.
High pressure blowers have straight radial blades (set at a 90 degree angle to the outer surface of the wheel hub) to keep them free of debris such as air and materials flowing through the Airflow. Our high pressure blowers include two main types of wheels: open and covered. The non-surge design allows them to provide constant performance through variable flow (low to medium) and constant pressure. The most appropriate wheel design is based on the combination of air volume and pressure, as well as the desired operating efficiency of the fan. In addition to the four pre-engineered models, our line of high-pressure fans includes two hyper-custom models with different base designs.
Our highly customized high pressure blowers are capable of handling fine dust or steam in high pressure applications:
Blowers can be roughly divided into two categories: impeller-based and positive displacement. Impeller-based fans have fins radiating outward from a rotating central shaft. Positive displacement fans use a mechanism to fill and empty chambers at the inlet and outlet respectively to create flow.
Centrifugal blowers, also known as radial blowers, are one of the most common types of high-pressure blowers. They use a rotating impeller blade to move air or gas. This blade extracts air from the centre of the wheel and pushes it towards the outlet at the outer edge of the wheel. Centrifugal blowers are often used for applications where medium to high pressure is required.
Regenerative blowers, also known as side channel blowers, are another popular type of high-pressure blower. They use an impeller with multiple blades that rotate at high speed inside a casing. This causes gas to be drawn in through one side and pushed out the other. One of the advantages of regenerative blowers is that they are very efficient and don’t require oil or lubrication.
Positive displacement blowers work by trapping a volume of gas and then pushing it out, creating a high-pressure flow of air. They are often used for low flow, high-pressure applications, and in situations where constant pressure is important. Positive displacement blowers come in many different types, including rotary lobe blowers, screw compressors, and reciprocating compressors.
Axial flow blowers work by pulling air into their inlet duct and then pushing it out through the outlet duct in a continuous flow. They are often used for high flow, low-pressure applications such as ventilation, and cooling systems. Axial flow blowers are also commonly used in air conditioning units and cooling towers.
Multi-stage blowers are a type of positive displacement blower, with multiple stages or compressors arranged in series. Each stage has its impeller and is optimized for a specific pressure range. Multi-stage blowers can achieve higher pressure outputs than single-stage blowers, making them ideal for high-pressure applications such as pneumatic conveying and gas boosting.
