Typed this out recently for another user in the PMs hope this helps.
So after some digging I found that the bouncer filters are simply ron-vik filters with their custom logo put onto it. you can buy them for half the price from Amazon.

I have a table that sits about 1' above the top of the keg and the flow is good enough. It will take about 10 mins to drain the fermenter. Could be slower depending on the amount of debris. There have been some occasions where I have had to clear the filter midway through to get it flowing.
Here is my process.
Equipment needed:
Filter with silicon tubing on both inlet and outlet. Liquid QD connected to outlet.
Liquid to liquid QD jumper
Gas QD to rubber bung (3/8" OD tube fits snugly into a standard rubber bung)
Keg A: Keg sitting full of star san.
Keg B: Empty Keg
CO2, Regulator
Fermenter with bottom spigot (spigot should have that little vent hole used to drain the line after the filter is closed, most have this)
I always have a keg sitting full of star san.
I connect the liquid QD to the filter (the QD goes on the discharge side of the filter. )
I open the lid of Keg B.
I connect the filter-QD assembly to the liquid post on Keg A.
I aim the other side of the filter (normally the supply side but here we are filling it backward to purge the unit)
I set my regulator to 10 PSIg
I connect the CO2 to the gas post on Keg A.
I start the flow of CO2
Once the filter is full of liquid i remove the QD from the liquid post on Keg A
I fold over the open end of the tube (supply side of the filter) and close it with a binder clip to keep it liquid full.
I then unse a Liquid to Liquid jumper to connect the liquid post on Keg A to the liquid post on Keg B.
I push all the liquid in Keg A out to Keg B via CO2
Once Keg B starts rumbling (Keg A is out of liquid and sending gas forward) I unhook the liquid QD from Keg A.
I remove the gas QD from Keg A after it has settled at 10 PSIg
Keg A is now empty and has about 10 PSIg of CO2 in it.
I then take the liquid filled QD assembly and remove the binder clip.
Then aim the open end of the tube at the opening of Keg B.
Quickly connect the QD on the filter assembly to Keg A to push the liquid out via CO2.
As soon as the filter is empty I unhook the liquid QD to keep from loosing too much CO2.
I close the open end of the tube with a binder clip again to keep it full of CO2.
I connect my Gas QD - bung assembly to the gas post on the keg breifly to purge the line with CO2 (2-3 seconds will do)
i remove the airlock on my fermenter and put in the bung with the gas line.
I collect my FG sample. This serves to flush out the spigot and draw a slight vacuum on the fermenter.
I connect the open end of the purged filter to the spigot on the fermenter.
I connect the liquid QD to the keg. This will cause the rest of the CO2 in the keg to whistle out of the vent hole in the spigot to flush out the spigot as well.
Once the spigot is good and flushed I pull the PRV on the keg to vent the last bit of the pressure. (dont want the pressure popping the top of the fermenter)
I open the spigot to begin flow of beer.
I connect the gas QD to the keg.
As the liquid fills into the keg the CO2 in the keg will now replace the liquid in the fermenter.
I know the process seems wordy but in practice setup takes no time.
It is absolutely critical to purge the filter well because otherwise it will sit full of O2 and then will cause great mixing with the beer as it is flowing causing unwanted oxidation.
