I know the trs is the sparkless model, but I’m wondering if there is a difference mechanically between the two?
Does the trs just have a spark less motor? They look identical to each other but the product catalogue says that the tr21 isn’t rated for use with flammable refrigerants.
I tried to ask CPS the difference between the two models and their response was basically “Dont use either for extracting CBD oil.”
I didn’t mention using it for extracting so they probably get emails like that all the time. When I tried to ask a follow up question they didn’t reply lol.
I have both in my graveyard. I tore them both down many times any they are near identical. Mine always leaked quick. That company that’s modding them look cool I’d prolly go with those guys if I wanted a pump and that pump was a trs. I run passive tho. I need to liquidate my graveyard…
