Putting a larger blower on a motor will over power the motor. You could cool the motor or expect the motor to fail fairly quickly. If you get a bigger blower you will get a bigger motor (either at the start or after the motor dies).</div><div><br></div><div>Another way to increase the air flow is to increase the airflow through the filter. Increase the surface area of the filters. Please note that a canister filter provides a LOT more surface area in the same size footprint. Factories have “Bag rooms” for their dust collection. You could just exit the dust outside for max air flow.</div><div><br></div><div>The last area where you can increase air flow is on the input side. Big pipe will increase air flow. The down side of large pipe is a decrease in static pressure. The ability to lift and move is with high static pressure. A Shop Vac can lift a cannon ball but it can’t collect fine saw dust from a foot away. Whereas an 8” pipe connected to a large DC can collect fine sawdust from 3’ away.</div><div><br></div><div>Recap:</div><div><br></div><div>Bigger blower (fan) needs a bigger motor</div><div><br></div><div>More filter increases airflow but bigger filters cost more.</div><div><br></div><div>Bigger pipes move more air but cant lift heavy loads.

Ordered and received a Wynn filter. Haven’t mounted it yet.<br>
Ordered an impeller upgrade from Rikon.<br>
The one used on the Rikon Model 60-200 is a 12 inch diameter unit that is a drop-in swap for the HF collector.<br>
The HF impeller is only a 9.75 inch diameter unit<br>
Unfortunately, Rikon says the new impeller is on back-order. Won’t be in until JUNE !!<br>
Seems far too many folks are buying this unit as an upgrade for their HF systems.<br>
O well.leaves me more time to work in the shop.<br>
