This very small Fan Blade assembly has 10
blades and the center hub together in one 
single unit.  It is designed for the very 
smallest Richard Glässer  169-170 
series of pyramids.  

Example: Mini Candle-less pyramid

These pyramids don't actually use candles but 
are placed where heat naturally rises near 
radiators, etc.
