Redesigning Shop

[BobLand]

Because of the noise and low hanging ducting I've decided to radically change the location and ducting in my shop. The shop is 15' x 30 but irregular in shape. Ceiling height is 82". Fortunately for me I'm a short 5'7".

I've identified a spot in the garage where I can isolate the cyclone from the main house so vibration wont be an issue. My concerns to date are:
1) Return air. The shop gets direct hot and cold air from the furnace/ac before the rest of the house. It is overly warm in winter and overly cool in summer. With that in mind, I'm wondering if it will be OK to not worry about return air. On the other hand, I could send it back to the shop or the furnace room which is adjacent to the shop.

2) Since hanging ducting on the ceiling bothers me, how about either directly on the floor or waist height? My reason for laying it on the floor is -- no hanging issues at all; ducting near machines will most likely be covered by support cabinets for that tool, i.e., no tripping issues.

3) As the main source of noise is now distant, will I get any noise from the ducting?

4) I get great suck as the system is now. If I add about 50-75' of ducting to what I have now, will I loose suck? Do I need to upgrade to the CV1800 body?

5) Can I run a remote? The CV1400 will be about 60' max, as the crow flies, from the cyclone to the furthest point in the shop. The shop is encased in concrete. The garage is attached to the kitchen, where directly below is the furnace room which is adjacent to the shop. I can get cell calls with no problem in the shop.

6) The garage get brutally cold in winter and blistering hot in summer. Will this be an issue?

I'll stop here as I'm sure you guys will bring up issues I haven't thought of.

Thanks,
Burt
