I have an H20 vertical releaser with submersible pump good for 4000 taps on continuous vacuum. It was only used 1 year, and never in the sun light so there is no fading. The pump is a 120-volt pump and comes with the check valve, 90's and all connections ready to use. Unit is in brand new condition, and can pump out with no problem at 28" this was built for high vacuum unlike a lot of the cheaper models. Brand new this releaser goes for $2,500 but, it is too big for my needs and would make a great releaser for someone on a larger scale. Give me a call at (802) 881-6Zero2six if you are interested, and I can send you pictures. Thanks
