Downdraft protein skimmer prototype uses modular neck modules

By on Dec 19, 2011


Cone skimmers, meshwheels and bubble plates are what we tend to compare in most skimmers nowadays but we often forget just how well some previous technologies worked. This strange looking prototype protein skimmer looks to be a downdraft or Beckett design that is using a novel modular neck to tune in your skimming needs, pictured here with probably way more modules than most would need.

Restricting a pump on the injector or even maybe a gate valve can work but those of you who have ran a downdraft realize there are times where you probably just wanted a bit more reaction time. This version of a modular neck protein skimmer would allow just that, letting you add or subtract a module to dial it in just as you need it — more modules for a dry skimmate and fewer for wet skimming.

    All we know is it is a prototype from Japan. Not sure the final company, possibly at Reef Octopus or maybe just a concept that stays on the drawing board.

    Not to post-crap, but the “adjustable neck” is one of the main advantages of a cone skimmer, but you dont have to add or remove parts.  For the most part, a cone skimmer “self adjusts” its neck diameter and height to match output if designed properly.  This is why many cone skimmers have slightly smaller neck diameters at the top (in the cup), so they can be adjusted down for smaller loads than the skimmer might otherwise be capable of.  All you have to do is adjust the water level (outlet standpipe or gate valve) and the extra back pressure on the pump will lower the air intake as well. 

    You can also run a cone body and a beckett and get higher air throughputs with smaller pumps (2200-2500lph with an eheim 1260 at 60 watts/90VA) than when on a downdraft.  Downdrafts place alot of back pressure on the pump as well as beckett output, which kills the potential air intake.
