Agitation and a strong Porty can get the job done. While it may not be as efficient as a truckmount, Brody said - he's a one man crew so he's OK if jobs take me a little longer. A rock solid Porty, along with a CRB or a rotary for pre-scrubbing, could be a cost effective approach. A couple of grand can purchase a good Porty https://www.excellent-supply.com/TruckPort-500-psi-HEATED-Extractor_p_345.html
I'm calling BS on this. Rick almost nobody that uses a porty regularly that is a carpet cleaner uses one with INTERNAL heaters. The life expectancy of the motor and pump with the heater in the same compartment is significantly lower. Also most porty guys (Willy is the main Exception but he is Canadian) focus their electric energy on suction.

You run an Excellent Business but I call BS....

Always use an external heater with its own power cord. Even then, it's a help but really won't keep up with a normal flow rate. Unless you do like Willy and use a kleenrite dual cord heater. Something like 3600 watts.

I agree. Heat in a Porty is not a big piece of the equation. The Truckport has a basic Porty heater if you want to use it. So it has heat - as Porty's go (but nothing compared to a truckmount). But for me, that's not the selling point. A Porty is all about squirt & suck. And on that end, the Truckport delivers.

For Porty cleaning, I'd place more emphasis on the A in the TACT pie and bump up the agitation. Temp can be a lesser factor if you have plenty of agitation. That's why I recommend the dual approach - pre-scrub first, and then rinse with the Porty.

P.S. I'm an Old Bike Guy too. :)
I know about you being a Bike man also---there are a few of us on here...

The problem with the portys with internal heaters is they usually put lower powered vac motors. This is so you can use the heater and vac motors at the same time. The same body with stronger vac motors and no internal heater is probably available, cheaper also.

I'm guessing your biking season is just starting to come on strong with the cooler weather---

The Truckport has 2 Airwatt vac motors producing 200 inches of water-lift. (See image below.)

This time of year, we ride early in the AM. We live near the Pinellas Trail - which is a converted railroad to multi-use trail. Nice for the road bikes! And on Thursday mornings we normally drive over to Alafia River where there are old abandoned phosphate mines that have been converted into some aggressive MTB trails. My wife and I start riding around 7:30 and ride for about 3 hours. So we try to get all our riding in early in the AM - before the sun gets too intense. In the cooler months it's nice since we get a little more flexibility with the temperature. The Florida sun is brutal!!!

Here's a picture of the Truckport with a vacuum tester - pegged at 200 inches of lift. For a Porty, it doesn't get much better than that.

Interesting.

So a Roots 47 Blower has around 140 water lift from memory.

Something isn't adding up for me here.
The 47 blower, assuming set at 14"hg is around 190 inches of water lift.

but alone this is a meaningless number

If you start looking at the curve of progressively larger blowers you see that they are capable of moving more air AT 14"hg . The actual work being done under a specific load so to speak.


Generally the lift of any given tm is set at 14" hg. The performance increase is seen in the amount of air being moved at 14hg.

So a good question is how many CFM will a truckport move AT that lift level?

Yes there are many questions to ask.

470 cfm from memory.

I like to set the Hg lift at 17

I edited for clarity and to fix a mistake/something that could cause confusion.

Here are the performance graphs of a 36 and 47 standard sutorbilt urai blower. Chosen because they share the same max rpm. Both are easily capable of 14"hg/190in of water. The difference is how much air is being moved at that lift level throughout the curve.

At the red dot in this image (3000rpm) the 37 is pulling 220cfm at 14". The 47 is pulling 360cfm.

I got a killer deal on three Devilbiss Compact HVLP spray guns. 1.4, 1.8 and 2.2 tips. Perfect shape. Industry leading pressure-feed guns, stack them up to an Iwata. And the price! They retail $550 each and I got all three for $140 from a retiring painter.
But they are hogs for cfm. I ganged my two 120V compressors and STILL cannot properly feed them. Close but not adequate atomization. So now I either paint the Piggy with a small Binks gun that has lower demand (and correspondingly lower capacity) or rent an asskicking compressor.
I could buy one too, but it must either be gas powered or 240V. Either way, an expense I do not want.

Sometimes it boils down to choices driven by circumstance, not desire. I’ll figure out a way to profit from those guns, but will simply do what I must to get my van painted without unloading a couple grand.

Same for using my porty. As things stand, a truck mount is not a smart choice. One day (sooner or later) it might be the only rational move. Meanwhile I build my suite of tools towards more capability and to be useful if and when I jump from electric to engin driven.

Also, I like penguins. They waddle around like fat little self-important Napoleons, squawk, eat shit and are government protected.

Just like some carpet cleaners, BAHAHAHAHAHAHAHA!

Some how I avoided this shit fest until 5 AM on a Saturday.

Obviously Brodie is in a bad place now, family health issues and living and running a CC gig in the second poorest state in the nation.

Id be far grumpier than him.


If does get a pos etm and ends up offing himself, Fred will be out rep at his funeral.






I see a pattern developing here.. :eekk::eekk:

It's nice to see that your mom had so many good years. I agree with what you said about the gift of life. You just don't know when it's going to end. My parents both died a few years ago and I miss being able to talk to them. You kinda take it for granted, and then they're gone. It's helped me to look at life differently. I'm looking forward to seeing them in the resurrection. Hang in there!
