I have 2 hepa certified vacuums for sale in New Jersey. These were used in a Pharmaceutical lab that went out of business.
First one is a Goodway VAC2HEPA wet/dry vac. This is a monster of a unit, It's dual motors can run 2 hoses at once, (I only have one hose). This model of VAC is usually used to clean out nuclear facilities and to purchase one new would cost several thousand dollars. I doubt it is really shippable by UPS or FEDEX as it is very large and heavy. It is perfect for attaching to paint strippers for serious production work.
The second is a smaller NILFISK HEPA vac that when new cost over $1000 I don't know the model number. It is extremely powerful, small, and quiet.
I had them both checked out by a local vacuum repair shop and they were given a clean bill of health.
Looking for the best offer as far as price goes.
