Found this thread after a search for "Circulator"

I inquired about this devise both by phone and email. The respondent was allegedly the inventor of the product. Below is the Email trail FYI.

Original Message:

I am wondering what effect "The Circulator" will have on filter back pressure. My 28,800 gallon pool is set up with a 1 HP super pump, Hayward Perflex DE filter to 3 jets in an ELL shaped pool (arranged on opposite sides from 2 skimmers).
Current back pressure runs about 12 PSIG without the Solar Heating System.

Also --- is there a model which dispersed at a 45 degree angle rather than
90 Degrees?

-----Answer-----
Hayward pumps/filter from their R & D division test the circulator,
And concluded that the circulator has little effect on back pressure.

The discharge opening is similar in size to the "D" eye ball that's
currently used in most pools.
The angle of water discharge can be change to various degrees (45 to 90
degrees) with a deflector that I'll put in your package.

I have not tried this product. The company offered a "special deal" $25.00 per each with a 30 day money back guarantee. Just not sure I need them since it would take three in my pool.
