01 / Engineering Overview
Pressure-First Fan for Small Airflow Duties
The 6-27 series occupies a different operating region from ordinary factory ventilation fans. Its airflow is relatively small, while available pressure is significantly higher.
This makes the fan suitable for equipment requiring concentrated high-pressure air delivery rather than large-volume room ventilation.
02 / Duty Position
When 6-27 Makes Sense
Small Airflow
Applications where only a limited volume of process air is required.
High Resistance
Systems with restrictive equipment, small passages or process components requiring high available pressure.
Process Air
Forced air for instruments, laboratory equipment, glass processing and selected industrial processes.
Not General Ventilation
For high-volume workshop ventilation, a general-purpose centrifugal or axial fan is usually more appropriate.
03 / Construction
Compact Direct-Driven Centrifugal Arrangement
01
Single Inlet
Compact centrifugal air path for concentrated pressure generation.
02
A-Type Drive
Impeller is directly driven by the motor for a compact overall arrangement.
03
High-Speed Duty
Reference performance is based on approximately 2900 rpm operation.
04
Filter Option
Legacy 6-27 configurations may include an inlet filter for clean forced-air applications.

10 / FAQ
6-27 High-Pressure Fan Questions
What is the main characteristic of the 6-27 fan?
The 6-27 series is characterized by very small airflow combined with relatively high pressure, making it different from ordinary industrial ventilation fans.
What is the reference airflow range?
Published reference performance covers approximately 72 to 621 m³/h.
What pressure can the fan provide?
Reference performance points cover approximately 6,600 to 7,492 Pa total pressure.
Is 6-27 suitable for workshop ventilation?
Normally no. Its operating region is better suited to small-volume high-pressure process air than large-space general ventilation.
Can the fan handle high-temperature gas?
The standard reference configuration is intended for relatively low-temperature gas. Higher-temperature duties require a different fan configuration and engineering review.
What information is needed before quotation?
Provide airflow, pressure, medium, temperature, inlet condition, rotation, outlet direction, voltage, frequency and quantity.
