QIYUE FAN product directions for these projects include FKZ / FKCDZ main ventilation fans, K / DK main or auxiliary mine fans, and JK / DJK or FK / FKD local ventilation fan directions.
01 / MAIN
Main Mine Ventilation
Supports the primary underground airflow network and mine ventilation station duty.
02 / AUXILIARY
Auxiliary Ventilation
Supports branch roadways, underground work zones and areas requiring additional airflow.
03 / LOCAL
Local Roadway Ventilation
Provides duct-connected fresh-air supply for development headings, roadway excavation and underground working faces.

02 · Main / Auxiliary / Local
Separate the Ventilation Role Before Choosing the Fan Family
The same mine may require more than one fan role. Main network duty, auxiliary branch ventilation and duct-connected local roadway ventilation should be reviewed separately.

Select the product direction according to mine type, ventilation role, airflow volume, system resistance, duct conditions, installation position and operating requirements.
Primary Main Ventilation
FKZ / FKCDZ Series Mine Ventilation Fan
Primary main-ventilation direction for metal and non-coal mine airflow networks where airflow, pressure and installation conditions are defined.
View FKZ / FKCDZ → Main / Auxiliary Efficiency Direction
K / DK Series Mine Energy Saving Fan
Main or auxiliary mine ventilation direction where the operating point, branch resistance and long-term efficiency are reviewed together.
View K / DK → Local Roadway Ventilation
JK / DJK & FK / FKD Local Mine Fans
Local forced-ventilation direction for metal and non-coal mine headings, roadway excavation, drifting, stope ventilation and duct-connected working-face air supply.
Local Mine Fan Naming and Selection
JK / DJK and FK / FKD designations can appear in metal and non-coal mine local-ventilation projects. For replacement work, confirm the original nameplate, motor data, duct diameter, airflow and pressure requirement instead of selecting from the model name alone.
JK / DJK
Existing mine-roadway and local-ventilation product direction for excavation, stope and underground duct applications.
View JK / DJK → FK / FKD
FK covers conventional single-stage local ventilation duties. FKD uses a counter-rotating configuration where greater pressure capability or longer duct duty is required.

Main ventilation, auxiliary branch ventilation or local roadway ventilation.
03
Airflow
Required air volume for the main network, branch roadway or local working face.
04
Pressure / Resistance
Required pressure or known system resistance from roadway and ventilation-network conditions.
05
Roadway / Duct Data
Roadway layout, branch route, ventilation-duct diameter, total duct length, bends and known leakage condition for local ventilation duty.
06

08
Electrical Supply
Voltage, frequency, phase, motor requirements, starting method and quantity.
09
Replacement Data
For existing-fan replacement, send the original model, nameplate, motor data, duct diameter, dimensions and required operating duty.
06 · Long-Term Operation
The Operating Point Matters More Than the Series Name
For long-term mine operation, the fan family should be reviewed together with the actual airflow and resistance duty, motor configuration, installation conditions and maintenance requirements.
01 / DUTY POINT
Airflow + Resistance
Match the fan direction to the required mine airflow and system resistance.
02 / LAYOUT
Mine Network Conditions
Roadway layout, branches and local ventilation routes influence the required fan duty.
03 / OPERATION
Long-Term Efficiency
Efficiency and motor configuration should be reviewed for long-term mine operation.
04 / MAINTENANCE
Installation & Service
Installation position and maintenance conditions should be included in the final configuration review.
07 · Engineering Path
Move from Mine Airflow Network to the Correct Fan Series
Use the system page to establish the airflow network and resistance first, then move to the product family that matches main, auxiliary or local ventilation duty.

08 · FAQ
Metal & Non-Coal Mine Ventilation Fan Questions
What are metal and non-coal mine ventilation fans used for?
They support main ventilation, auxiliary ventilation and local air supply in metal mines, non-ferrous mines, gold mines and underground engineering projects.
Which fan series are used for non-coal mine main ventilation?
FKZ / FKCDZ is the primary main-ventilation direction on this page. K / DK can also be reviewed for main or auxiliary duty where the project operating point and efficiency requirements fit.
Which series are used for local metal-mine ventilation?
JK / DJK and FK / FKD are local-ventilation directions used for roadway excavation, development headings, stopes and duct-connected working-face air supply. Final selection should be based on the actual airflow, duct resistance and installation conditions.
What is the difference between FK and FKD?
FK covers conventional single-stage local ventilation configurations. FKD uses a counter-rotating arrangement and is reviewed where the ventilation system requires greater pressure capability or longer duct air delivery.
Can an old JK or DJK fan be replaced with an FK or FKD model?
Replacement should be reviewed from the existing fan nameplate, motor data, airflow, pressure, duct diameter and installation dimensions. Do not select a replacement from the model name alone.
Should the fan be selected from airflow alone?
No. Airflow should be reviewed together with system resistance, ventilation role, duct conditions, mine layout, installation position and operating conditions.
Why is mine layout important?
Roadway layout and branch conditions affect the ventilation network and influence the required fan operating duty.
What information should be sent for selection?
Send the mine type, ventilation role, airflow, pressure or resistance, roadway or duct information, installation position, operating conditions and electrical supply.
