Hot air rework station pumps - food for thought ?

Vacuum cleaner air pump cutaway

Yes, I was thinking of the impeller design with its shaped blades. The Quick blower certainly seems to have had thought put into its design. Hence this thread. I am interested to understand how hot air station manufacturers created the required performance from centrifugal blowers. I still wonder why they took that path rather than the equally ‘simple’ regenerative blower design.

Interesting..... look at this teardown of a vacuum cleaner air pump.... it has curved ‘fin’ profiles built into the casing. I wonder if that is similar to the ametek dual turbine idea ? It has a pretty standard looking impeller but exhausts air from multiple ports around the casing rather than just one.

FWIW if you look at blower fan used in Hakko FR810B, it's trash in comparison. Way more noise produced at similar airflow. From Quick I only hear what seems to be a motor noise and noise from air coming out of the nozzle. Hakko sounds like a cheap vacuum cleaner.

Hi Wraper,

Yes I have watched the Quick 861DW hot air station being used on the NorthridgeFIX YouTube channel and whilst you can hear the PACE fume extractor running, you do not hear the blower of the Quick station. That is a very nice unit and if I were in the market for another I would buy a genuine Quick 861DW  :-+ Sadly there are fakes that can make obtaining a genuine Quick product more challenging. I do not mind seeing clones with different makers names, but the fakes pretending to be Quick products are a real PITA.

The HAKKO FR810B blower ..... it looks the part but, as Wraper has stated, it is the internal design that matters !

Not a cheap blower at $80 either.
