Dust Collector Motor Replacement

Probably not. The air flow is created by the impeller (fan). Unless the impeller speed increases, you won’t see any air flow increase.

Yeah, that’s what I figured. Thanks anyway.

As Sawkerf said, the airflow won’t increase by going to a larger motor. The problem is the diameter and design of the fan impeller. Most DC’s suitable for woodworking have fan impellers at least 12” in diameter with a minimum of 1 1/2 HP and 3450 RPM. I would guess that your 1/3 HP unit has a much smaller impeller.

You can put more than one blower in a system….

For example, you can put use a seperate blower as a booster next to a machine that has an especially heavy load (i.e. a big planer). Or you can simply put two blowers in series feeding into cyclone and then a bank of bags or filters

So I’d recommend hanging on to that unit and coming up with a plan that incorporates it with a second blower some day.

What is the inlet diameter? The only reason I ask is: typical 1 HP dust collectors have an impeller that is around 9-10”. The 1/3 HP would be able to turn an impeller of this diameter if the system is air starved ie the inlet is less than 4”. If the impeller is around 10” you could add the 1.5HP motor and open the inlet size to 4”. It will at least get you started in ever continuing journey of dust collection! Keep in mind that the felt bags are real dust pumps and inherently allow particulate matter through in order to increase air flow. Most good bags are good down to 1 micron which means the nasty stuff gets through even after the bags are seasoned (which takes a long time.) But filtering down to 1 micron is better than nothing at all. Have fun on your journey…it’s a wild one.
