This is the website of the guy who makes the DTR. I strongly recommend adding on the 'direct air' package if you are going to order a DTR.
And ordering some check valves like these (https://www.amazon.com/dp/B07YTVR6LJ/ref=cm_sw_r_cp_apa_i_gtd1DbGPNZCAF) to make using the direct air method even easier for you.
