Does this auto adjust the speed depending on the impurities in the air?

No. There is a three-speed knob and the user sets the desired speed which stays constant until the unit is manually shut off.

Of course not! To be honest: it's too much money for a "box with a fan" behind a hepa filter... I suggest try another air cleaner.

I'm not aware of it adjusting the fan speed automatically. There may be some type of switch to set it to do that and I'm just not aware of it. I've just had no desire for it to adjust the fan speed automatically.

Yep, you can turn the fan on or set it to to automatic. You can also control the speed.

There is a manual adjustment knob just like on a normal variable speed grinder/polisher. We haven't clocked the speeds but, slow is really slow and fast is good enough. We use it mostly for polishing and metal prep (high grit) not material removal. It doesn't get used everyday, but it is $300 well spent when we do use it.

I don't remember if it had a setting to change the speed or not. However the balls did come out at various angles and speeds. Keep in mind that this is a low quality product. We used it once or twice and wound up throwing it away.

No, but it does have a speed adjustment dial. Works really well for speed control.

Yes it does this automatically. Just make sure your coffee is ground properly for the automatic setting. You can change the settings manually if you want it set differently. Works well.

I personally hoped it was automatic when I bought it, but you have to wind in manually.

No it does not automatically adjust. It's very bright and easy to see from our church stage, but the only negative is that you cannot stop the colon between the minutes and seconds from blinking...other than that it's pretty nice.

Yes. In the auto mode there is a setting. It is a fantastic digital. I use mine al the time.
2094848
Yes, absolutely. I often do just that, manually adjusting speed and incline, and tracking distance.
532225
Yes, it does. You can turn the oscillation on and off independently from the fan speed.

Depends on what you mean. It would measure airflow speed at its sensor, in the direction the sensor it pointing. The impeller is quite sensitive and I would think might be adequate for air speeds relevant to HVAC, but please keep in mind I am not a HVAC professional. It would NOT of course measure airflow volume directly. I think one of the air speed readout settings is feet per second, if those are the units most relevant for HVAC in the US.

Yes, you can adjust the speed with a controller. I did it and not problem so far.

there is a speed dial that allows to increase or lower the speed.I find this to be an excellent method to vary the speed..

There are three speed positions on the adjuster but between them it seems to act like a variable speed control. I have not found a need to adjust the speed in between settings but there may be conditions of material that do need that level of control. It's a good unit and has met my wood working needs very well.

No, it doesn't stop automatically. It does tell you the flow rate, so you could work with that data to stop at the appropriate point.
