Yes, it is a 'brand name' import version.
You also have the benefit that CPC is a proper UK company, part of the Farnell group. So you have all the normal provisions, returns, warranty, safety assurances, etc. associated with buying from a reputable UK company.
P.S. The best way I've found to avoid clogging is to hold the PCB (near) vertical and the gun horizontal - it sounds odd but is surprisingly natural in practice, it also stops you putting excessive pressure on the solder pads.
One other thing, the ZD985 seems to have adopted a black plastic solder debris chamber, while the Duratool retains the original glass one (which afaik can also be retrofitted to the ZD985 and is only £2.45 from CPC).
