Better to push or pull gas through a filtration unit?

[sibrit]

To get a better flow, should a VP be fitted to the filtered output to pull gas from the filtration unit to storage, or have the VP push gas into the input of the unit, or both?

I don't use volume pumps at all in my filtration system. Never had any problems with the gas flow to the filtration units, they seem to work extremely fast (using parallel filtering, not serial).

Good question, I been pulling with VP at the point of entry and that works good for flow and emptying the lines however, those pumps use a lot of watts even at idle.

400W for a volume pump while only 5W for a filter (both at idle). So I am currently building switches so one switch will turn on just what I need for a specific ore

Thanks for the replies. My filtration units are in parallel but it seems to take an age to extract those last few MOL's. Really hate to see it go to waste. :)

mine is also in parallel and I tried it with a standard valve and it was not really working well for me. The pipes try to equalize volume between itself and its containers which is not what I want. Running the volume pumps cleans out the pipes rather well and puts that all into the tanks where I want it. (like in a matter of a min or two when smelting 50 units of something.

I guess the risk with putting the VP on the input is that if the Filtration Unit stops working, you'll end up with an over-pressure event. At least with pulling gas from the unit into a tank, the tank can handle higher pressures.

I tested my entire system setup without pressure regulator and its working fine. HOWEVER, I only smelt one thing at a time.

What I consider a negative is the amount of power it uses. I dont have a power issue but in general I am a power nerd so that bothers me

the filtration unit will pull its input quickly faster then a VP on 100% and send to output and waist just as fast. its best to have no pumps or valves in the system if under 60MPa. pumps and vales are good for maintaining temp. meaning pumping the gas to a room,tank, in a block or temp regulated room. a pipe to a tank on the output pipe with only pumps after that pipe/tank would be best in my opinion. that tank is only needed when melting ice ,your MPa in the pipe can quickly reach 60 if u have a small pipe network on the output

I am confused.
If I use a volume pumps near all my tanks (one per), I get pipes upstream cleaned out in seconds after smelting. If just manual valves it never cleans out (and I understand why it wouldnt because by game rules it tries to equalize the entire line with what is in the tank) so what would one use instead?

To get a better idea of this, I did some tests with volume pumps and atmospherics, and put it into a simple guide: https://steamcommunity.com/sharedfiles/filedetails/?id=1650561161

how many pipes do you have between your filter and your tanks? pretty much every time i build my gas storage i only use 1 section of pipe in between my filter/tanks (i just a junction) and have a valve on the output so i can keep the gas in the tank/1 section of pipe and then ill open the valve whenever i need the gas.

Are you filling tanks (stationary) or portable tanks?

For stationary tanks there is really no point in trying to empty those pipes. Just look at it as an extension to your tank volume (the more pipes the bigger volume you can stock).

For portable tanks you could use a pump to get everything out, but I doubt this is very usefull unless you run lots of pipes or switch filter types and want to avoid contamination.

This is the usual setup I have for my filtration network.

In this case I have not used any Volume Pumps as I find the throughput of the Filtration Units is enough to empty the waste pipe network. However, I do not know if they will struggle if the pressure in the storage tanks gets too great.

filtration units dont seem to lose any output with more pressure in the tanks, they just keep pumping gas through and the first thing to fail will be the pipe. so no you wouldnt need pumps forcing gas into/out of the filters. i run the same set up and have no issues, just have to monitor pressure in the tanks so you dont blow the pipe
