Thanks.

We had these in a nursing facility, ask kindly for another unit. They become more noisy after they have been worked-on and their aging process. New ones are definitely quieter. I'm assuming this is a rental unit?
If you bought it, you can put a longer tube/extension, and put it in another room. You shouldn't enclose it.

Yes, it's a rental unit. It has a 50 foot hose on it and it's down the hall and in the family room about 40 feet away, but
it's a lot noisier than a mouse ****in' on a blotter. :-(

They have a compressor in them and can become noisy...I would ask for another unit, preferably, newer.
