Q: Is this the membrane for the Spectra Ventura 150 Deluxe Watermaker Spectra Part Number FT-MB-20

Yes, this element will work for that system.

Q: is this just a part,or the whole thing,,I do not see how this could possibly work ?

Hello! If I understand your question correctly, you're trying to determine whether this is a complete water filtration system or just a component of one. This is the replacement membrane for a seawater desalination system. It is a consumable part - not a stand alone system. This is what goes inside of the white membrane housing/pressure vessels. I hope that makes sense?

Q: Will this fit the Katadyn Survovor 35?

This will not work, search for "Katadyn 8012793"

Q: Did anyone try this on a dessalator 60 water maker ?

My friend on another boat did use this part with his dessalator. Tip for dessalators... if you are struggling to get the end caps off the pressure vessel to get to the membrane (this part) then remove the "cage" that holds the end caps in place and just bring the watermaker up to pressure slowly. One end or the other will pop out due to the pressure inside.
