Looks like a hairdryer but nice circular flow...

Awesome. A spray bar AND a lily pipe type flow......

the lighting products on the last bit of the video look interesting as well

It's nice that there's a Chinese company that breaks the sterotype...

What a great product! Go maxspect.

Impressive, something I think most of us have designed in our head but don't have the money to produce a good prototype. Hope they make a micro version, if it ends up as stylish as there lights I'm sure I'll need one.

They had these at Interzoo - the amount of water they can shift is amazing.

It's an underwater cross flow fan - from Wikipedia
'The cross-flow or tangential fan, sometimes known as a tubular fan was patented in 1893 by Paul Mortier,[10] and is used extensively in the HVAC industry. The fan is usually long in relation to the diameter, so the flow approximately remains two-dimensional away from the ends. The CFF uses an impeller with forward curved blades, placed in a housing consisting of a rear wall and vortex wall. Unlike radial machines, the main flow moves transversely across the impeller, passing the blading twice. The flow within a cross-flow fan may be broken up into three distinct regions: a vortex region near the fan discharge, called an eccentric vortex, the through-flow region, and a paddling region directly opposite. Both the vortex and paddling regions are dissipative, and as a result, only a portion of the impeller imparts usable work on the flow. The cross-flow fan, or transverse fan, is thus a two-stage partial admission machine. The popularity of the crossflow fan in the HVAC industry comes from its compactness, shape, quiet operation, and ability to provide high pressure coefficient. Effectively a rectangular fan in terms of inlet and outlet geometry, the diameter readily scales to fit the available space, and the length is adjustable to meet flow rate requirements for the particular application.
Much of the early work focused on developing the cross-flow fan for both high and low-flow-rate conditions, and resulted in numerous patents. Key contributions were made by Coester, Ilberg and Sadeh, Porter and Markland, and Eck.
One phenomenon particular to the cross-flow fan is that, as the blades rotate, the local air incidence angle changes. The result is that in certain positions the blades act as compressors (pressure increase), while at other azimuthal locations the blades act as turbines (pressure decrease)'
It's a nice re use of existing technology. They've been used as cross flow (water) turbines for years along with millions in cars AC units, fans etc. I wonder what patents they managed to secure? Can you get a patent for waterproofing something and sticking it in water?
