Application field for every
blade type by considering
the nature of the conveying
medium.
1) For larger solid material in
the conveying medium with
additional tendency to extremely
heavy solid build-up
2) For applications with high
quantities of particles to be conveyed
as e.g. wood chips or
gypsum
3) This impeller with radial ending
blade tip is particularly suitable
for conveying media with
heavy solid build-up tendency or
with high dust load.
4) For clean or slightly dusty
conveying medium, preferred if
fitting with wear protection is
required
5) Often used for hot air circulation

FEM Analysis
Our plug
fans achieve maximum
efficiencies (often up to 80%)
by using our method of pinpoint
accuracy in the
fan design for
the specific performance data in
combination with the integration
of the constructional engineering.
In turn, the complete commercial
aspect of the system
benefits from this excellent
efficiency,:
- Compact
fan design
- Energy efficient execution
- Low operating cost
We offer plug
fans for circulating
ambient air at 20°C as
well as plug
fans for extreme
process conditions e.g. melting
furnaces with 800°C.
The impeller geometry as a
freedom of choice
The 9 different intake/discharge
diameter ratios for 5 different
blade types and 21 impeller
sizes enable us to choose from
ca. 1,000 available impeller
configurations to customize the
impeller exactly to your requirements.
Whether it is wear
protection in case of abrasive
material, special material for
high temperatures or alloy steels
– we are offering you „Your System
Solution“.
