Product description

This Square D Pumptrol 9013FHG19J52X air-compressor pressure switch controls an electrically driven air compressor in a power circuit when the adjustable threshold upon falling is reached and is set to turn off at 125 psi. The switch has a 1/4" NPT external fluid connection and is suitable for use with a lower-horsepower motor with 1.5 hp or less. The non-adjustable differential is 30 psi, and the adjustable cut-out range is 70-150 psi. The switch is diaphragm actuated and has a fixed differential. The threshold, or setting point, upon rising adjusts with a screw nut. The switch has screw terminal electrical connections, and two 2-pole NC contacts open on rising pressure. The enclosure is National Electrical Manufacturers Association (NEMA) Type 1 and Ingress Protection (IP) 20 rated. The switch is Underwriters Laboratories (UL) Listed and Canadian Standards Organization (CSA) certified. This switch includes a 2-way pressure release valve. Square D Pumptrol pressure switches are manufactured by Schneider Electric.

Researchers estimate that the oceans produce half to two thirds of all oxygen on Earth. This production is heavily influenced by oceanic plankton, including drifting plants, algae, and some bacteria that are able to photosynthesize.

Wow,didn't know you were allowed.is it expensive?

Maybe they could show the examples that are helping corals…they only show examples nurturing algae growth…

It's good concept but bad design....I can see a storm being able to move them and tumble them around....more thought should be put into the design so its not a stand alone rock, but one that could be stacked, like triangles, which would be better at deflecting wave force....and could be interlocked...the larger the structure gets, the more fish will come.

Sheri Russ-Hoehn 👀👀👀 I choose this one

reef balls are a different concept than sinking, ships and other parts! yet studies on the effectiveness of sinking cars etc. is still in question: For example the paint as well as the whole car (or whatever) could leek toxins. And yes if they get moving in storm it could cause more harm than good. Best example are tire reefs in Australia where loose tires destroyed compensable amounts of coral reef. Also artificial reefs in some areas seem top be not well accepted I believe there are some studies from Italy on reef blocks! However I am totally for the reef balls and similar structures (if probably secured and right material used) as well as seeding native bioengineer species.
