Good Durable Tire Inflator?


I am looking for a good, durable tire inflator that can be used for a variety of purposes including:

a) keeping our Safari SS25 tires at pressure (65 psi)
b) flushing water out of the pipes when winterizing
c) pumping the high pressure tires on our tandem recumbent bike (100 psi)

Because the 12V power outlet in the truck is plus or minus 35' from the tires, I would need a combined length of 12V power cord and air hose of at least that much distance. I have begun combing the websites for products and can find NO combination that long. Therefore it looks like I'll have to go with a cordless rechargeable. I did see the Black & Decker AS1500 12V/Cordless Air Station that meets this requirement. I am wondering if anyone out there has had experience with this particular brand/model, or any other brand that meets my requirement and would be durable. Would appreciate the benefit of anyone's wisdom and recommendation! Thank you.

Any of the 12V ones that I have ever used tend to be noisy as heck, and weak as, well, weak.

If you really feel you need a 12V one, be sure to actually try it out on your TT before buying.

We just drag along our 120V compressor from home. It's a smaller one, but can pump up anything relatively fast. If you are checking tires very regularly (minimum every morning and evening when we are on the move) you will hopefully catch any problems before they get dramatic...

I bought a small one a Walmart that works fine on tires, even truck tires to 65 pounds, but the requirement of blowing the water lines will require lots more volume than any of the small 12 VDC compressors that I have seen.

I've been happy with the Black & Decker Electromate 400. It's inflator keeps the tires at 65 psi (but usually only has to bring them up a couple of psi).

We have a 25 ft Safari Rear Bedroom. When I hook the electromate up the city water input, it blows the water out of the kitchen, bathroom and shower faucets. I only open one faucet at a time. The faucets are all about in line with the water inlet on our trailer.

It also has an inverter so you can run a house fan for a couple of hours too.

inflator OR compressor?

tank or tankless?

hard wired or not?

12v or 120v ?

pressure rating and duty cycle?

and the most important question, how much $$ do ya wanna spend?

-first lets solve the 35 ft of 12v cord issue...

there are 12 outlets INSIDE the stream, so use them when inflating the trailer tires...

using the trailer outlets means a 10-20 ft COILED 12v extension cord solves the distance issue...

(be aware of the amp/volt requirements and limitations of these extension cords)

skip looking for a battery version it will be expensive and have VERY limited utility.

-at 100$ or less there are a couple of directions 4 a portable 12v or a small 120v...

the small tankless 12v inflators WILL air up a tire, but take a lOOOOOng time doin it.

for example going from 55psi to 65 psi might take 10-15 minutes PER tire.

i carried and used one of these for 5 years and it worked ok.

slow, but it would eventually get the tires UP to pressure, and it still works fine.

many versions but this one is adequate at 50$ and i still use it occasionally.

search the brand/name online, i had LOW expectations for this 35$ purchase but it worked fine, still does.

because i wanted something with more UMMMMPH! a small 120v was purchased.

see post #5 here...

with the small (1 gallon?) tank, it was much faster to inflate and can be used to blow out the lines too...

lots of versions and brands in the 100$ price range, but one does need AC juice (or a genset) to use it...

again still in service at 5 years but as the garage compressor now.

last year i added a 12v HARDWIRED compressor and reservoir tank to the truck...

it's installed UNDER the bed (inside the double wall) on the frame rail

a couple of companies market these but they are available from 100s of truck accessory websites and stores...

VIAIR Corporation - Portable Compressors

these are 200-500$ with pumps rated for 25% up to 100% duty cycles...

the duty cycle is HOW LONG the pump can run continuously...

relative to how HOW LONG it must be rested 2 avoid OVER heating and failure.

this is important when inflating large tires like those on the truck or trailer.

with/out a tank they also make portable versions of the airlift/viair noted above,

that either plug into a 12v round outlet or connect to the battery POSTS...

typically they come in a bag with a long coiled air hose like this...

again many versions and price points and vendors (camping world, and most truck enthusiast stores)

there are versions at harbor freight for less money but durability may be an issue.

mine is 100% duty cycle, does tires quickly and will blow out lines and even work with LOW volume air tools.

the tank is always FULL of compressed air at 170 psi, for a speedy tire or blowing job...

it's probably more than most folks want or need.

many other examples in these threads and the LINKS within...

so again sort of price point and features when choosing, from the many options.

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.

I had a 125 inflator from Black and Decker purchased at Home Depot for about $45. It worked o.k. until I tried to inflate 4 tires on the Airstream to 65 pounds and also those in the tow vehicle to 55 lbs. After 20 minutes of hard use, It stopped working and could not be user serviced.
I purchased its replacement at Ace Hardware for about the same price and like it much better as it has a user replaceable fuse. It is a Cambell Hausfeld 120 volt inflator. It will inflate tires to 80 lbs + (that takes a bit of time) and has plenty of capacity to blow out the water lines.
Both inflators have air pressure gauges. The Black and Decker had an automatic shutoff which is a convenience.
I have one of those 12volt Truck Inflators pictured in 2air's post. It is heavy duty and has a cooling fan. It works o.k. and is durable but is inconvenient to use on the Airstream because of the 12v power.

air compressor

Proper blowing out of water lines, for winterizing purposes, takes a 5 horsepower compressor to do it correctly.

Smaller compressors will take a long time to get the job, almost done, but not completely done.

The volume of air pumped into the water lines, "MUST" be huge, or else you take the chances.

I use the Masterflow Q-Max from Costco. Fast, high volume, high pressure, and quiet. Has to be hooked up direct to your battery as it draws almost 30 amps. $50 bucks at Costco or can be found on line for $60. Yes, easily blows out water lines. Best bang for your buck, period.

I have a cordless model that I am happy with - it will top off my tires to maintain at 65 psi. I have not winterized, so I can't comment on it's ability to blow out the lines. This model holds a charge for a very respectable amount of time and is easy to store/recharge. It isn't fast, but is adequate.

I use a TRUCKAIR 12 volt compressor, slow but gets the job done. It may no longer be available, haven't checked.
I also made up an extension cord to plug in the trailer plug on the TV and terminated in a lighter plug so it is easier to get at the trailer tires.

None of these will be much good for blowing out lines. We prefer to winterize with pink anti freeze . Blow out may still leave a little water in a low spot or valve

My inflator works well to blow out the lines. I let the pressure build to about 20 pounds and then open one faucet at a time letting the pressure build back up each time I turn on a faucet. I have a bypass on my hot water heater as it takes quite a while to put enough air in the tank to pressurize it.
A big compressor is overkill as you don't want the air pressure going above 40 pounds under any circumstance and this happens fast with a big compressor with all the faucets off and the hot water tank bypassed.
Previously, I have drained the holding and water tanks and put rv anti freeze in the grey and black tanks and sink drain taps.
Last, I take the inlet and outlet off the fresh water pump and turn it on for a second to blow the water out of the pump.
This has worked fine for me in multiple below zero winters.

Warn Industries - Air Products: WARN Air-Power SPC
I have this 12-volt Warn Air-Power SPC, which is reasonably priced and strong enough to fill the tires to 65 lbs in short order. After filling eight tires, you'll want to cool it a few minutes before you store it. I really struggled with the 12-volt vs. 110-volt compressor arguments but I'm glad I went with this one since I can use the trailer or truck batteries to fill tires anywhere.

I also have this compressor. I am very pleased with how it works. It is definitely not one of the plastic toy kind that I have been disappointed with in the past.

Tire pressure 34ft

Good Evening,

Hopefully we will be picking up our 34 footer this friday (and a long 1400 mile drive home). Not knowing if the previous owner will have the manual, I would appreciate if one of you could let me know what is the recommended tire pressure. They are GYM. I am used to 65 psi on our Safari.
