Believe it or not the valves on the recovery tank are also a huge restriction. On a typical system you would gotten that done in a fraction of the time. Great video, nice presentation !
Always love your content but if I may expand a little… The length of the hose makes a large difference as well. Example an 8 foot 1/4” hose reduced to a 5 foot 1/4” hose will speed up your evac time by 40%. (Assuming cores are removed) In this video the head to head battle would’ve been a 1/4” hose the same length as the 1/2”. Regardless, there’s no denying the science, the 1/2” hose with cores removed will give the best evac time.
hi Once u get down to required micron 500 although flow is important under pull down it just requires time at this level ,the flow slows anyways . For small repairs fridges , freezers , room a/c , small mini splits , automotive it would be great for larger hoses but not absolute . Recommended even in a mid size or larger domestic install . Dont forget the dedicated vacuum hoses what ever the size *** Automotive has a huge issue they vac out for 30-60 mins . 30mins usually by 99% techs What happens is the system has spent no time at below 500 micron level DOH ...... The system is/could still be wet ......................... thankyou saves time 50% time only 20 mins to 500 micron
On new installs, 2 ton and 80 ft line, I would use the NP4DLM 4 cfm battery powered pump instead of the 2 cfm. Don't pull through gauges and use large diameter hoses

Thanks Jim!

Of course, length play a huge factor.
That bluvac app is so sweet, I've been using it for a while. I needs one of those navac pumps though.
The app is sweet, yah and the pump is fantastic!
I uses the Navac NP2DLM vacuum pump and it is the real deal.
yes it is
I want that pump! 🤘🏽
It's awesome!
You will luv it
This should be perfect for under counter reach in.
I gotta try this
Nice video brother!
thank you man, much appreciated!
Awesome channel! Any durability updates for this pump?
Very durable so far, used it a ton

thank you
Great video, could it work for 2 ton refrigeration 80ft distance line set?

Takes Makita 18v batteries too
Is that the 3ft tru blu hose?
Yes
