The high-pressure centrifugal mining fan can be used for local mine ventilation and ducted extraction, including the removal of underground welding fumes and post-blast fumes and dust. For long duct runs or systems with higher resistance, a suitable fan model and motor configuration can be selected based on the required airflow and pressure, taking into account the properties of the air or gas handled, duct layout and installation conditions.
High-Pressure Centrifugal Mining Fan
1. Product Overview
The high-pressure centrifugal mining fan can be used for local mine ventilation and ducted extraction. Applications include underground welding fume extraction, post-blast fume and dust removal, and exhaust ventilation in work areas. For long duct runs, restricted duct diameters or systems with higher resistance, the fan model can be selected according to the required airflow and pressure, with the configuration determined by the properties of the air or gas handled, duct layout, power supply and installation conditions.
2. Key Features
High Pressure Output: Designed to increase air pressure and move air through duct systems with higher resistance. For long duct runs, multiple bends or connections to other equipment, the appropriate model is selected based on the required airflow and pressure. Specific performance should be checked against the selected model's fan curve.
Long-Distance Duct Applications: Can be selected for ducted extraction in vertical shafts, inclined shafts and mine roadways, taking into account duct length, diameter and layout, together with the required extraction airflow. Actual extraction capacity depends on the fan operating point, duct resistance and air leakage.
Centrifugal Design with a Scroll Housing: Air gains energy as it passes through the impeller, is collected by the scroll housing and is discharged through the outlet. The impeller and scroll housing work together to increase pressure and move air, while the connected inlet and outlet ducts direct the supply or exhaust airflow.
Configuration Matched to Operating Conditions: The fan model, speed and motor power are selected using the required airflow, pressure and fan performance curves, taking both extraction requirements and operating efficiency into account. A larger motor or higher pressure rating alone is not a sufficient basis for selection.
3. Typical Applications
Underground Welding Fume Extraction: Can be used with collection inlets and extraction ducting to remove fumes locally at welding work areas, conveying contaminated air to the discharge or treatment location specified in the ventilation design.
Post-Blast Fume and Dust Extraction: Can serve as a component of local extraction systems for conveying fumes and dust-laden air after blasting, in conjunction with the mine ventilation system.
Mine Duct Ventilation: Local ventilation and ducted extraction requirements are assessed in relation to duct layouts in vertical shafts, inclined shafts and mine roadways. The fan is then selected for the corresponding operating point.

The photos illustrate the products and shipment preparation. The supplied unit's design, connection dimensions and configuration are subject to the selected model and the agreed technical specifications.
5. Fan Selection and Configuration
Fan selection is primarily based on the required airflow and pressure. Both values must correspond to the same operating point, and the pressure requirement must be identified as total pressure or static pressure. Once the operating point is confirmed, the fan model and configuration are determined based on the properties of the air or gas handled, power supply and installation requirements.
Selection Information | Details to Provide |
Required Airflow | Provide the design airflow in m³/s or m³/h and specify the corresponding operating conditions. |
Required Pressure | Provide the pressure required at the specified airflow in Pa, and state whether it is total pressure or static pressure. |
Air or Gas Handled | Specify the extraction application, air or gas properties, dust content and temperature. |
Power Supply | Provide the voltage, frequency and number of phases. |
Installation Conditions | Specify the installation location, space restrictions, inlet and outlet orientation, and duct connection dimensions. |
Other Requirements | Where applicable, provide the altitude, ambient temperature, operating mode, and any explosion-protection, corrosion-resistance, noise or control requirements. |
If the required pressure has not yet been determined, provide details of the duct diameter, length, bends, branches and connected equipment so that system resistance can be calculated. Duct diameter and run length are considered as part of the overall selection process and should not be used alone to determine suitability.
For high-temperature or corrosive media, or environments requiring explosion protection, the suitability of the specific fan model and configuration must be confirmed separately.
6. Request Fan Selection and a Quotation
Please provide your required airflow, pressure and operating conditions for fan selection and a quotation. Specific performance parameters, suitability for the air or gas handled, and the supplied configuration are subject to the technical specifications agreed by both parties.
