The Ultimate Compressor Review 2021

[Frederic 14,997]

Offroading in the UAE desert requires you to deflate your tires. If you are lucky to be exiting nearby a petrol station, you can make use of their compressor to inflate your tires before going back on the tarmac, but that is not always an option. For that reason, having your own compressor will be a necessity and this should be a piece of your off-road kit that you know won't leave you stranded.

Depending on the size of your tires, or the type of compressor you are using, inflating can be a task that will take you anywhere between 2-4 minutes and sometimes up to 25minutes. With the hot blazing sun shining down on us most of the time, we want to get this job done as quickly as possible.

In below article we will be going through some of the technical issues related to using a compressor, and what to look out for when purchasing one.

Hot, Hotter, Hottest

The main problem with all compressors is that they run hot. The friction that occurs when air molecules are squeezed together generates heat. This heat can be felt at the piston head, but also on the hose itself. That is also the reason why most compressors have cooling fins and a piece of metal pipe at the outlet to allow the heat to dissipate and to avoid the hose from getting too hot. You should always be careful in handling a compressor after inflation, as it might burn your hands.

It is normal for parts of the air compressor to get hot sometimes, especially if you are running the compressor for an extended period or if it is particularly hot outside. The best thing is to keep the compressor in the shade, run it for a limited amount of time, and not to exceed the duty cycle that is mentioned in the technical details. 

What to look after when buying a compressor ?

1) Warranty. A premium brand should provide 4-5 years warranty which will make the higher price worthwhile. This is hard to find nowadays.

2) Output in liters per minute (lpm). The more the better of course. Everything from 50lpm upwards should be fine. Some will show a rating in cfm (cubic feet per minute). 2.3 cfm = 65lpm. Unfortunately these values are not always very accurate, as manufacturers can put whatever they want on the box, and on top of that, some manufacturers will give a flow rate at 0psi (free air delivery), while others will give the flowrate at 40psi (which is quite demanding for the compressor). 

3) Duty Cycle: Air compressors heat up when running so most have a limited consistent output before they need to stop and cool off. This run time in-between cycles is called a duty cycle. Manufacturers typically represent run time with a number, such as “20”, which means you can run the compressor for 20 minutes every hour. sometimes they show a percentage. 20 minutes would indicate a 33% duty cycle. Keep this in mind when you are using the compressor every week. Avoid exceeding the duty cycle time as in a short period of time it would overheat / destroy the compressor.

4) Quality of the coiled hose, pressure gauge, and clip-on chuck.

5) Automatic pressure shut-off function. This makes the compressor stop automatically when you are not engaging the trigger. 

6) inline fuse and thermal overload protection. Will come standard with premium models.

Below a typical specs example of a Bushranger Black Max:

Duty cycle is 30 minutes @40psi at 24°C ambient temperature. Obviously the ambient temperature will be much higher for us here in the UAE, so you will need to take that into account. Keep the compressor in the shade while using (or even on the inside of the car if possible) and keep your engine running. These compressors are rated to work most efficiently at 13.8 Volts, so your alternator should be running. 

Below i will be going through most of the brands we have encountered in the club, and how we can rate them:

Premium Brands (****)

Brands like ARB, Bushranger, TJM, Dobinsons, and Mean Mother, are the most famous premium brands that will be providing a quality unit that should last years. ARB and Bushranger/Viair have the advantage that you will find spare parts for them, so if you are interested and savvy, you can rebuild your compressor later on.  

Price range of these compressor is from 750 AED upwards up to 2500+AED. The main reason why they cost more is due to the quality of materials used, higher duty cycle of their compressor, and of course marketing as well.

ARB

ARB has the single cylinder unit for about 1000AED, while its big brother will be around 2,700AED.  They have by far the best quality of hoses and gauges.

MeanMother

The Mean Mother Adventurer is the only brand/model we know of in the UAE that offers 5year warranty, hence this model has become very popular in our off-roading community. You will find the Adventurer III model for around 750AED (150lpm), but now there is also the Adventurer IV which is having slightly better performance (180lpm) and costs about 999AED. We have heard about a few models failing but were replaced within warranty.

Bushranger / Viair

Bushranger/Viair has a range of different models with output ratings from 52lpm up to 72lpm.  (Black Max for 800AED and Max Air III for 1120AED). The Max Air III  has an automatic pressure shut-off. Their compressors are extremely reliable, but i have never been impressed with their yellow plastic coiled hoses and clip-on, except for the black hoses they use on the old SuperMax and the newer Max Air III model. Their smallest model (RV Air for 599AED) is the minimum in terms of output flow (52lpm) and will take quite some time to inflate your tires, but should work fine.

Dobinsons

Dobinsons have the Zenith model (170 lpm) that is being sold for 999AED. Quality looks top notch with good set of accessories and backed by a premium quality brand.

 

Midrange Brands (***)

 

Golden Camel

The "Golden Camel" brand with its red compressors, sold in single cylinder and double cylinder models are fantastic performers for the price (200 AED for the single big cylinder 160lpm, and 280AED for the double cylinder compressor (300 lpm). Yes the hoses break, the electrics fail sometimes, and it won't be the most reliable compressor, but for that price it's worth a try if you want it. You will find the hoses also separarely in DM, and if you are a bit handy with a soldering gun you might make an attempt to replace the switches or solder a wire back on.

They now even have a mighty big 4-cylinder unit, but we have not been able to get feedback of these units for a longer period of time in use. 

The problem nowadays is that you have even "fake" Golden Camel compressors, who look 100% identical, but their quality is even more of a question mark. I recently bought one and it started overheating and shutting off after only two tyres. The vibration coming from the compressor makes me wonder about the tolerances used in the manufacturing process. On the other hand i also have a single cylinder Golden Camel that has been going strong for 3 years now and never failed. 

Vitaly

Vitaly is a brand that basically re-labels these Chinese compressors and sells them at a higher price in hardware stores like ACE and Speedex. Again they are a bit of a gamble and the only advantage you will have is you will get at least 1year warranty through these stores.

T-Max

These compressors are looking very similar to the DM Single big cylinder compressors and the Mean Mother Adventurer. There is a smaller 72lpm unit and a big 150lpm unit. Prices are similar to Vitaly, and T-Max seems to be a reputable Australian brand, so perhaps the build quality will be a slight notch above the DM compressors.

Volcano

I recently stumbled upon this brand via a shop in Ajman. They are manufactured in Taiwan and the K100 twin cylinder model costs about 350AED, is very small, and serves great as backup compressor (flow rate of 60lpm).  

Their biggest compressor model is the B850 which is being sold for about 650AED. Have seen them on sale in DM as well. They come in a sturdy box, with decent hose (like the Bushranger top model) and have a pressure gauge with automatic cut-off.  Flow rate is 98lpm. 

Brands/ Models  to avoid:
-The smaller "Golden Camel" Compressor. Absolutely worthless. Also sold under the "X-Cessories" brand name.

-Mini compressors to connect to the cigarette lighter: Will last only a few drives. Not made to inflate weekly from 15 to 35psi, unless you want to wait for 25mins or longer. Will overheat easily because of this. These are made for sedans and bicycles.

The Black and Decker and Michelin models seem to work better, but it will take you upwards of 25 minutes to inflate your tires. If you happen to have one of those, i strongly recommend to only inflate to about 25psi you can then drive to the nearest petrol station and use their compressor.

If you are in the market of buying a new compressor, i hope this article can shed some light and useful information that will guide you in the right direction. As you can clearly see, inflating tyres on a 4x4 in the summer heat requires a big powerful compressor that can quickly inflate your tyres before overheating or shutting down.

Thank you Fred, this is a very informative article about compressors, I have spent a week and got pretty much the same information on certain points.

Addition: Working pressure - This is should be understood as the efficiency of the air pumping into tire.

Below is my observation to validate:

single cylinder, air flow volume 150L/min, max working pressure 150 PSI, 3mins+ to fill up factory sized tire

twin cylinder, air flow volume 300L/min, max working pressure 150 PSI, 1.5mins+ to fill up factory sized tire

A shop clerk in DM told me if the golden camel logo is a sticker on the box, it is the "fake" ones

I went to those shops myself and found out the same🤣, even a pc X-cessories with melted hose in display.

Vitaly ones come with 1 year warranty I guess is because they know too well that the golden camels roughly stop working after a year. Basically you are spending 100 AED more for the warranty.

So I decided to try my luck and got a golden camel single cylinder, thinking that single cylinder should produce less heat than the twin cylinder one while the working pressure remains the same, only the air flow volume is halved, im ok with it taking 3+mins to fill up each tire while chitchating post drive

The Golden Camel single cylinder is the one I purchased when started off-roading and later gave it to Vanessa. She’s still using it every week and never broke down. (Fingers crossed). I’m a bit handy so whenever something breaks I’ll tear it apart and make one good compressor out of 3 bad ones 😅

A good thread for anyone joining in new and looking for compressor wish had this insight when I spent 70-80 aed on these...😃😃

[Looper 1,129]

I have a 70mai air Compressor along with my onboard ARB one for when I have to top up air because I deflated more or to level the tires after a drive. This one goes into the cigarette lighter and auto inflated to the set pressure. It also shows pressure in .1 increments. 

I have OCD that all my tires have to have the same pressure on my car center console screen, else I pull my hair out or have sleeplessness. 🤣

[Enrico Biscaro 206]

Great info as usual. Where one can find the premium brands? Amazon does not seem to have 

[Niki 2,850]

@Enrico Biscaro :

• Mean Mother - google search mean mother compressor dubai, the first non-Ad result is the UAE dealer (where i purchased from) 
• ARB - have a branch in International City and trade via every offroad shop or ACE in the UAE.  
• The Dobinsons Compressor which has a tiny tank (approx 900-1kaed) and they are available direct from Dobinsons, Amazon or a google search lists (second result) a supplier. 

I have switched to the ARB portable twin with a tank and couldn't be happier.... if you have the budget just jump straight to that setup vs taking my route which had me holding 3 compressors at one stage prior to the current setup!

@Looper i also have a mi one along with mean mother for precisely the same reason 😁

@Niki

Like you, I also have a MM compressor, purchased 2-3 month  ago. I am considering an onboard set up now. Did you manage to sell off your MM compressor with your recent conversion?

Hey @topgear I did … it’s a great option for many as has a long warranty.  I now run the ARB dual with tank (portable one) and have the built in compressor as the back up unit.   Maybe offer it up on a new thread and for future absolute newbies who don’t yet have one.  I sold mine privately but was going to post on here.  
 

another option is to make the mean mother an onboard setup… I had fabricated 2 cages in the trunk so didn’t have the space to mount it .. I was told it is very easy to mount and could give you an option.
