What is the physical difference between a 10 HDU, 15 HDU and a 20 HDU? I am thinking of purchasing a 10HDU, but the specifications on the flows are too low. My situation is more like the HDU 20. Can the 10 HDU be converted to a 20 HDU?

What items are required and what sort of investment is it?

Thanks in advance

The 10, 15, and 20 HDU use the same body just some parts are bigger and others are smaller depending on the model. If you had one and wanted to go to the other it wouldn't be hard to change them out and would cost around $300 for the change of parts. If you wanted to give us a call I will be able to give you a full breakdown of the parts and give you some other options.
