New SAS Sentry Air Systems Fume Extractor #SS-300-PFS These units were bought for a big project and never used. Have been stored in storage units. May have minor scratches since they are out of the original box.

This unit was slightly used indoors in a climate controlled environment and is still in excellent condition. These units new sell for around $2000. I have no other use for this unit any more so that is why I am getting rid of it.
