JDS Air -Tech 750 ER

Jorge

Among the things I must be thinking on, Shop Dust Collection is tops.

In 2006 my lathe was the Nova 3000, squeezed in the boiler room between the boiler and the fuel tank in a 10' x 12' room. Sanding was torture, with a full beard the respirators never did filter out the fine stuff, so I did bite the bullet and got a JDS Air -Tech 750 ER, Installed it on arrival and by chance, the plumber guy came to tune up the boiler when I was wiring the 750 ER. He did not let me complete the job saying that that unit was to overpower the blower in the burner and the flames could come out, as he did not trust me, he and his assistant took the unit down and put it back in its box and moved it to the wood shed.

Now that the new shop is up and have ample space and the boiler will be in it's own separate room, I will install the 750 ER right away to take care of the fine dust.

Where in relation to the lathe it should be? The shop space is about 2700 cubic feet and plan to hang a shower curtain to contain the shavings to a small area around the lahe.

Down the road I am thinking a cyclone. What is the foot print?

The JDS Air-Tech 750 ER is an ambient air filter. It should be installed in a central location -- away from corners and heating/air conditioning vents. It's designed to capture the fine dust that floats in the air long after you've quit sanding. It's NOT a substitute for a respirator or a dust collector. Those, in that order, should be your primary lines of defense.

Since you have a beard, I strongly recommend a powered respirator that has a full face shield. Those units have a gusset that fits under your chin. They work very well with a full beard. An example of these is the Trend Airshield. 3M also makes several PAPRs (Powered Air Purifying Respirator), such as the Airstream and the Versaflo. Because they are powered, the gusset does not need to seal tightly against your skin. The filtered air flows over your face and down past the gusset. That airflow prevents unfiltered air from entering the mask.

That is a very competent air filtration system. It is the unit I have installed in my shop.

You want to situate it where it moves the most air with the least turbulance, and where the biggest creator of fine dust (probably the shop cat :D ) is in front of the intake. Imagine your shop is an oval Nascar track. The filter should optimally be placed near the ceiling at the start-finish line, moving air in the direction of traffic. Situate it with the lathe, or whatever creates the most fine dust, coming out of turn four. Your shower curtain, however, will interfere with the circulation and collection of dust by the JDS, and probably trap it around your nose. At least, it is movable, so it could be pulled into position when you are turning wet wood, and pushed aside, or even adjusted to help channel air from the lathe to the filter, while you are sanding.

Your boilerman was full of it. Since the air filter only circulates air within the shop, but does not affect the pressure differential between the air intake to the heater and its exhaust port (chimney), it should have had no appreciable effect on the operation of the furnace. If you had erroneously mounted the JDS through a wall with the intake in one room and the outlet in another (or even worse, outside) then it could have had the effect he described.

Thank you for the info David,

Yes I have a dust collector, a small but usable unit until I can get the Cyclone.

I'll save for the Airstream, hopeful to get it in January.
