For somebody who began an air tool assortment 20+ years prior, air actually checks out. However I am presently not an expert specialist, every one of my tools returned home with me and I use them consistently in my home shop keeping up with my own armada or chipping away at others' vehicles as a side hustle. A long time ago when I initially began purchasing tools, electric/battery controlled stuff wasn't generally excellent. Today they are brilliant and as a rule out perform even my top of the line air tools. Nonetheless, that includes some significant pitfalls since I'd need to purchase all new cordless tools. For what reason would I do that when my air tools turn out great?
I have buys a couple cordless tools however, for the most part for remote work at my homestead or when I'm out and about an extended get-away. I had a couple trailer tires victory on our last excursion and I had them changed in under 10 minutes out and about with assistance from my cordless effect. Cordless tools today appear to be legit and assuming that I were simply beginning, I'd put more cash into those than I would air tools.
I guess every specialist could have their own response to this. I'm not a repairman but rather I have bunches of tools, air controlled and electric. I work on vehicles and a wide range of different things around the carport/house/yard.
Contemplations:
1) Air controlled tools are a lot more affordable than battery tools when analyzed at comparative quality and power.
2) You basically must have an air blower assuming you are accomplishing vehicle work (tire filling, cleaning things, cleansing things, and so forth) So you have a blower regardless. Furthermore.
3) chipping away at a vehicle is constantly done in the carport. So opportunity of development isn't required, your 25ft self-withdrawing air hose covers everything. In rundown, air fueled tools cost less, don't expect you to keep a lot of costly batteries healthy and charged, and have just the negligible bother of being fastened to the air blower which is as of now arranged not too far off at any rate. For tools I utilize away from the carport, battery power is the best approach. Hauling at least 100 feet of hose around is a significant PITA.
For decades if you needed (nut busting torque) you needed a pneumatic tool. Not sure even with the most advanced tech that you would have the same ability on cordless. Not only that but pneumatic will go all day as long as the compressor kept up, but it was noisy and hazardous with the high pressure required, but a garage needed the air anyways for other parts of the servicing of vehicles so pneumatic made sense.
Now even in our industry cordless is making an entry even into tasks always associated with larger electrically operated tools such as pipe threading; and even medium level air tool like Jack hammering, and corded core drilling are possible with the new MX battery platform.
With all these cordless options now in the home building field, don't get as much call to run temp service and wireing, even temp lighting is going away with all these cordless job site lights.
Talking as somebody who went through years in the air blower industry, when power tools originally advanced, electric tools were no counterpart for pneumatic particularly for convenient, high-force applications. As others have expressed, that has changed in last decade or somewhere in the vicinity. Air actually enjoys a benefit where very high force is required. Weighty hardware mechanics who need ft-lbs or more to eliminate a rusted 2" shaft nut actually use air.
Auto body shops used to shower combustible paint toward one side of the shop and the non-starting part of air tools was a benefit. The paint stalls expected today to meet EPA necessities have the combustible fumes basically contained so this isn't as significant.
Where pneumatic misses the mark is proficiency. It takes something like a 10HP blower to ceaselessly run a 1HP air engine! I don't remember the specific numbers, however it's awful.

I think you mean efficiency instead of proficiency. The ratio of "energy we want" to "energy we pay for".
In the upper limit of perfection, the turbine of the air engine and the compressor that powers the air source, could both be reversible processes, and be 100% efficient. But with practical factors that come in to play for building the machine in reality, is a much more difficult to mitigate the inevitable irreversible processes with the extra moving parts in a pneumatic power transmission system, than it is to mitigate the inevitable irreversible processes when electricity is the medium of power transmission.

As an auto technician, it’s a tough call. The tools you choose depends on the specific job at hand, and in the case of pneumatic vs. cordless, the decision likely isn’t going to be one or the other, it’s going be both.
Pneumatic tools have traditionally always been the tried-and-true auto technicians’ choice, to the point where the sound of an air tool is the most recognizable and defining characteristic of an auto shop over any other. Air tools have always been the “staple” power tools because anywhere there’s an auto repair shop, there will be compressed air, so there’s always a power source for an air tool.
You never have to plug them in or charge them, you don’t have to replace the batteries, worry about them going dead right in the middle of something, or worry about them being superseded by a higher voltage model that requires a different battery. Compressed air is compressed air, and it always will be.
I don’t imagine this advantage of air tools will ever change as compressed air is too valuable for too many reasons. Air tool popularity can also be related to their fundamental mechanical nature. There’s something about a tool that can sit for years and years, and still work perfectly when you dust it off. Of course, our tools don’t sit around, but you get the idea.
Air tools also have the weight advantage with lack of a heavy battery, and modern materials have not only made them lighter and more durable over the years, but they’ve gotten smaller in size allowing better access into tight areas. Improved ergonomics and balance have been fundamental design considerations for years, and along with better sound control and increased power, air tools will always have a place in an auto shop.
So, air tools came out swinging, but cordless can throw a few punches of its own with some of the drawbacks to air power. One is the air delivery system in shops, i.e., the hoses and lines. More often than not, system pressure is fine, but the dynamic pressure, or the pressure available when the tool is in use, is considerably less than it needs to be for proper air tool performance. The problem is usually caused by restrictions in the lines or hoses, but cordless doesn’t care.
Citing poor air tool performance due to the shop air system – that’s hitting below the belt. But air tools come back with a few jabs of their own, with some manufacturers designing built-in gauges on air tools to indicate if the proper dynamic pressure is available.

Now cordless has a sucker-punch. What’s that hose? It’s always there and you can go only so far, not to mention tripping over it, having to clean it and hanging it up. And, what about one of those days when there’s a lot of air being used, and you need to wait for the compressor to catch up? And, air tools need to be oiled before and after use to keep them in good condition, and some require greasing. That’s a lot of maintenance.
Then air comes back with a quick one, two. Batteries are expensive, which is why we usually only have two. If it has a battery, it will need recharged at some point, Pneumatic, on the other hand, keeps going and going (couldn’t resist) with the power source that’s always there. In cases where you’re doing constant sanding or drilling, pneumatic is often the only way to go.
Air tools have traditionally had the power advantage that no electric tool could touch, but cordless is sitting back, waiting to deliver a left hook.
Everyone knows how good batteries have gotten thanks to Lithium-ion (Li-ion) technology. Although cordless tools lose the weight battle, primarily because of the battery, higher voltage and advanced battery technology is providing the power and shaving off weight at the same time.
Two performance factors that can be attributed directly to a Li-ion battery are run time and output consistency. There was a time when you always needed a battery on the charger, and diminishing output was an expected performance aspect of a cordless tool. Now, you may get a day’s use out of a charge, and power output remains consistent with no drop off, down to the last ounce of energy.
The increasing use of brushless motors has added another level of performance to a cordless tool. In the automotive business, we’re all familiar with brushed motors, and we know the brushes wear as the armature and commutator rotate. In a brushless motor, the armature is fixed and surrounds the magnets, which rotate with the motor shaft. This eliminates the brushes, commutator and the related friction between the two, and the current in the armature is electronically controlled.
The armature windings can also be larger since they are on the outside, and the motors can therefore be more powerful. It’s the little things such as this that add up to keep cordless tools in the fight with the power of pneumatic. Maintenance is also less, and when time is money, that’s an important factor.
So, the big question, who will take the title? This is a fight that will go the distance.
I’m not willing to give up my air tools or my cordless tools. What does the future hold? Will one gain the upper hand over time? It’s hard to say, but for now, I’d say it’s a pretty fair fight.
