01 / Engineering Overview

Non-Coal Mine Fans Should Be Matched to the Ventilation Network

FKZ / FKCDZ series is intended for non-coal mine ventilation projects where fan performance has to match the complete underground ventilation system. Typical project directions include metal mines, non-ferrous mines, gold mines, chemical mines, building material mines and underground engineering.

The fan should not be selected only from casing diameter, motor power or appearance. Required airflow, roadway resistance, fan station arrangement, reverse-airflow planning and future operating changes all affect the final selection.

01 / AIRFLOW

Start from Ventilation Demand

Required airflow should come from the mine ventilation calculation for the actual operating stage.

02 / RESISTANCE

Match Roadway Resistance

Total pressure should be checked against roadway resistance and the actual mine ventilation network.

03 / LAYOUT

Review Fan Station Conditions

Surface or underground layout, connection direction, available space and maintenance access should be confirmed.

02 / Ventilation Network Matching

Why Mine Ventilation Network Data Matter

Many axial mine fans look similar externally. For a non-coal mine project, the important question is whether the selected fan can operate at the airflow and pressure required by the complete mine ventilation network.

Airflow Demand

Defines the ventilation quantity required for the mine or the specific production stage.

Roadway Resistance

Determines the pressure requirement that the fan must overcome at the intended airflow.

Fan Station Layout

Installation position, connection arrangement and available space affect the practical fan configuration.

Reverse Airflow

Reverse-airflow requirements should be identified during selection when the mine ventilation plan includes reverse operation.

The selected fan should match the ventilation-network operating point rather than simply provide the largest available airflow or motor power.

03 / Series Direction

FKZ or FKCDZ: Which Series Should Be Checked First?

FKZ SERIES

Standard Non-Coal Mine Axial Ventilation

FKZ is normally reviewed first when the mine ventilation network requires a standard axial-flow solution with a defined airflow requirement and a moderate pressure requirement.

Reference range
Airflow: 2.0–164.2 m³/s
Total pressure: 38–2409 Pa
Motor power: 1.1–250 kW

FKCDZ SERIES

Counter-Rotating Structure for Higher Pressure Demand

FKCDZ is normally considered when counter-rotating performance is required to provide stronger pressure capability for larger or more complex underground ventilation networks.

Higher network resistance
Main fan station duty
Reverse airflow planning

04 / Selection Path

Selection Path for Non-Coal Mine Ventilation Projects

The model should be narrowed down step by step from the mine ventilation conditions instead of starting from a preferred fan size.

Confirm Mine Type

Metal mine, non-ferrous mine, gold mine, chemical mine, building material mine or other underground project.

Confirm Airflow

Provide the required airflow from the mine ventilation calculation for the relevant operating stage.

Match Resistance

Check roadway resistance, branch losses and the required pressure margin.

Review Fan Station

Confirm surface or underground installation, inlet and outlet direction, available space and connection conditions.

Check Reverse Airflow

State whether reverse airflow is required and provide the expected reverse operating condition.

Select FKZ or FKCDZ

Compare the required operating point with standard axial FKZ or counter-rotating FKCDZ performance.

07 / Performance Guide

How to Read the FKZ / FKCDZ Reference Data

The table is intended to show performance direction. A fan number or motor power should not be treated as a complete selection result.

Series

Shows whether the model belongs to the FKZ axial or FKCDZ counter-rotating series.

Fan Number

Indicates the model-size direction and should be evaluated together with airflow and pressure.

Airflow

Compare the listed airflow range with the calculated ventilation demand.

Pressure

Check whether the pressure range matches the calculated roadway resistance at the required airflow.

Speed

The listed rotational speed belongs to the reference configuration shown in the table.

Motor Power

Motor power follows the selected fan duty and should not be used as the primary selection criterion.

09 / FAQ

FKZ / FKCDZ Non-Coal Mine Fan Questions

What is the difference between FKZ and FKCDZ?

FKZ is the standard axial-flow direction. FKCDZ uses a counter-rotating structure and is considered where the mine ventilation network requires stronger pressure capability.

Which series should be checked first?

FKZ can be checked first for standard axial ventilation with a moderate pressure requirement. FKCDZ should be reviewed when network resistance or pressure demand is higher.

Can the fan be selected only by mine type?

No. Mine type only defines the project context. The model still has to match required airflow, total pressure, roadway resistance and fan station conditions.

What if the total pressure is not yet available?

Provide the available roadway resistance or ventilation-network calculation data together with the required airflow for review.

Why does the fan station layout matter?

The installation position affects connection arrangement, airflow direction, available space and maintenance conditions, so it should be reviewed before final selection.

Should reverse airflow requirements be provided before quotation?

Yes. If reverse ventilation is part of the mine ventilation strategy, provide the requirement and expected reverse operating condition during selection.

Are the listed models the full product range?

No. The listed rows are reference examples for preliminary comparison. Final operating points should be confirmed from the calculated ventilation requirement.
