Having lots of product to select from, attractively arranged and kept clean and dusted is a far cry from boxes of finished product cluttering the walkways or shelves.

I started out in this industry working for a guy that had the theory that having finished product in the showroom showed his clients how busy he was. From a salesperson stand point, I hated it because I kept trying to show clients product, and would trip over boxes as I was trying to get close to the wall to pick up a product and hand it to the client. He wrapped the products in newspaper so they wouldn't bump as they were transported, so you saw boxes all over with crumpled newspaper sticking out of the tops of the boxes.

I'll bet your showroom doesn't not match this 'clutter' I'm referring to.

Your post made me shudder.

No the show area is neat in that respect, just too many products per shelf.

That seems to be the key.

When you finally understand it completely... it changes.

Hermes,
You mentioned a noise reduction device for the exhaust. I would appreciate tips on the construction of this. Recently the exhaust noise has become an issue for us due to a relocation.

What we used to do in recording studios for the air conditioning ducts was to build a box with twice the square area of the duct. Looking from the top of the box was the opening to the duct in the lower section...

I'll attach a picture.

The top, bottom, and walls were covered with fiberglass. It muffles all but very high and very low frequencies.

OOOOoooo we are having BIG issues with exhaust noise now that the weather is getting warmer and neighbors are opening doors/windows. I'm so concerned of the 747 impression we're producing here!

I can't wait to read more tips/tricks on this thread! Keep them coming!!

So Harvey - can you use a 4" car muffler for this application?

Pardon me...I'm just a girl! :)

I think you willl have to try a Diesel Truck surpressor for a 4" pipe.

How much CFP are you pulling ??

1100 CFM....... How far is the laser from the vent outlet..........

Just 1 laser or is there more hooked up??

I'm running just under 300 cfm and I can push 15-20 feet with no problem

Right now, the laser is only 6 feet away from both the blower and exhaust hole.

My current set up has the motor at ankle level on the floor with it venting directly via a dedicated hole outside. (this setup is in a garage.)

We want to change the config so that the vent hole will be farther from the laser - approx. a 30 foot run - thru 4" PVC. We also want to vent it out thru the roof making it push 30 feet and up thru the roof.

Do you know if it will be quieter if I use this setup or would you recommend some sort of muffler?

I should hope that by venting through the roof the noise factor would be projected up out of ear shot.

How noisy is the unit running on the floor by your feet??

I'm not a noise expert but I believe the current setup of the exhaust directly venting to the outside with no piping/tubing between the exhaust and the outside is the problem. It is incredibly loud.

There is 6' of flex hose from the laser to the blower and then there is 8" from the exit of the blower to the outside.

But before my husband begins cutting holes in the roof, etc., I'm hoping to get some type of reassurance that it's only got to get better (i.e. quieter on the outside) with his efforts.

But where is the fan unit going to be loacted??? up in the attic???

That's what is making all the noise..

Is the Smell a major factor to moving to the roof. If not a small fan is in order...

Just my recomendation. At 300cfm I have to check the "on" switch to make sure mine in even running.......

Well now that's interesting....It is the noise - not the smell - that is a major concern. There is absolutely no question when mine is on.

Maybe you've got a point...my unit would not be moved in this new set up. It would stay on the floor in the shop. My thought (or wishful thinking) was all this PVC run of pipe was needed to get the noise level down. But maybe what I need is a smaller/quieter blower??

What unit are you using?

You say you have to even check your 'on' switch to see if it is running. How is the noise from the outside?
