A particular diffuser for skimmers by RedStarFish
This article is also available in: italiano
A diffuser is a particular tool that spreads the bubbles in the body of the skimmer, right after the exit of the pump. It has a peculiar importance for their diffusion, both for their size and “turbulence“. In hydraulics the term turbulence means that the water particles collide many times. We can speak about turbulence when the Reynolds number is higher than 2100, assume it, because the explanation would be long and complex.
So the diffusion plates present a series of holes that serve to spread the bubbles in the above area. RedStarFish had the intuition to develop the simple design of the holes using conic-cylindrical fissured shapes.
We liked very much the result in the skimmers on trial in the booth. The foam seemed very much and well distributed.
The new skimmers RS-N Plus by RedStarFish
The skimmers designed for this diffuser are three, named RS-N Plus,and they’re the RS-N130 Plus, the RS-N170 Plus and the RS-N230 Plus.
|Model||Recommended aquarium||Pump||Pump consumption||Dimensions||Aspirated air|
|RS-N130 plus||400-500 liters||HP-1500L||12 watt, DC 24V||200x190x485 mm||600 l/h|
|RS-N170 plus||500-700 liters||HP-2500L||25 watt, DC 24V||230x210x530 mm||900 l/h|
|RS-N230 plus||800-1.000 liters||HP-4000L||35 watt, DC 24V||285x260x600 mm||1.450 l/h|
I think the name of the model indicates the diameter of the body of the skimmer. The numbers RedStarFish declares seem to be very competent. The values of the aspirated air seem very realistic so we wanted to suggest you the recommended aquarium too. But for hard corals SPS probably you should consider half of the minimum value.
But it’s the foam that seems to be really great, as you can see in the following pictures:
The pumps are obviously electric, and, according to their names, pumps are capable of a flow rate of 1.500 l/h for the smaller and of 4.000 l/h of the bigger. And, obviously, used with a brush impeller the numbers are very different.
Now we can watch these skimmers closer in the next pictures and appreciate their constructive quality.
The skimmers of the series RS-C
RedStarFish has in its catalog also more normal skimmers of the series RS-C. They’re 5 with increasing characteristics.
They’re always skimmers with regular direct current pumps, with treated air of a minimum of 600 l/h and a maximum of 3.600 l/h.
But in the catalog exist a lot of other things, like a triptyque of beautiful sumps in acrylic.
I models are three, D-50, D-80 and D-100. They differ for the length in centimeters expressed by the number of the model, so they’re all wide 45 cm and high 38 cm, for lengths from 50 to 100 cm.
And more again seaweeds reactors.
And enormous skimmers for industrial purposes.
For more informations you can visit RedStarFish official page. Unluckily they aren’t currently distributed in Italy, but we hope that someone will soon take care of that. We leave you also the link to our editorial of the CIPS 2017, where you can find also the links for the articles we’ve write about and we’re going to write.
