High Pressure Fan Applications

High-pressure fans are configured for industrial systems where long duct runs, filtration equipment, process equipment, or conveying pipelines create substantial pressure resistance.

Pneumatic Conveying — Deliver the pressure required to move plastic pellets, grains, wood chips, powders, and other dry materials through enclosed pipelines.

Industrial Combustion — Supply primary or secondary combustion air to furnaces, boilers, rotary kilns, burners, and thermal processing equipment.

Dust Collection & Filtration

Maintain required airflow through baghouses, cyclones, scrubbers, and other high-resistance filtration systems.

Process Drying & Cooling

Provide high-velocity process air for metal cooling, textile drying, chemical processing, and material dehydration.

Industrial Exhaust

Handle high-resistance exhaust systems where airflow must be maintained through long duct networks and process equipment.

FAQ

Q: How do I select a high-pressure fan?

A: Start with the required airflow and pressure at the operating point, then check the gas temperature, medium, system resistance, fan speed, motor, and installation conditions. Airflow alone is not sufficient for final selection.

Q: What is the difference between static pressure and total pressure?

A: Static pressure represents the pressure available to overcome system resistance, while total pressure includes both static and velocity pressure. The pressure basis should be confirmed before comparing fan performance curves.

Q: Can a high-pressure fan handle long duct runs?

A: Yes. Long ducts, multiple elbows, filters, and process equipment increase system resistance, which is one of the main reasons high-pressure centrifugal fans are specified. The fan should be selected for the required airflow at the calculated system pressure.

Q: Can I select a high-pressure fan if I only know the airflow?

A: Not for final selection. Airflow is only one part of the duty point. If static pressure is unavailable, duct dimensions, duct length, fittings, filters, or process equipment and existing fan data can be used to establish the required pressure.

Q: Can a high-pressure fan be used for pneumatic conveying?

A: Yes. High-pressure centrifugal fans are commonly used to move pellets, grains, powders, and other dry materials through enclosed conveying pipelines. The required pressure depends on pipeline length, bends, material handling equipment, and downstream resistance.

Q: Can you replace an existing high-pressure fan with a different model?

A: Yes. Existing fan performance, motor data, connection dimensions, and installation layout can be reviewed to determine a suitable replacement rather than matching the model number alone.
