Tow-behind air compressors took the world by storm a few decades ago when they met a simple need: mobile compressed air, wherever you want it. It was a game-changer for a lot of industries.
But once the novelty of tow-behind air compressors wore off, their limitations became apparent. Manufacturers began to look at innovative ways to solve these problems and, in the 1980’s, companies began to invent new air compressors that would revolutionise mobile air once again.
Today, companies who need compressed air have a choice of compressor options, many of which make more sense than a tow-behind. Let’s talk about 9 reasons you may want to ditch your tow-behind air compressor:
If you have a tow-behind air compressor, chances are you’ve become a bit of a pro at dragging your trailer through busy streets, reversing without jack-knifing, and circling job site lots of times until you find a suitable parking spot. This might even seem normal to you. But there’s a better way!
When you ditch your tow-behind air compressor and switch to a vehicle mounted air compressor instead, you’ll feel liberated. You’ll suddenly have more freedom! Driving, reversing, and parking all become second nature again, and you won’t be restricted by your trailer’s capabilities or driving expertise.
In addition consideration to towing licences and tachographs can be forgotten.
If you’re a business owner, you’ll have peace of mind knowing your staff aren’t trying to negotiate your expensive equipment in heavy traffic, park in precarious situations, or backup in environments where space can be highly limited.
Speaking of which…
Dropping your tow-behind can also improve your access to important job sites, as tow-behind compressors are clunky and can limit your work opportunities. A lot of mobile service work is in remote or off-road areas, requiring vehicles that can navigate the challenging terrain. Trailers don’t tend to do well in tricky environments, requiring additional time and care to get to the work site—if accessible at all.
Tow-behind compressors take up a seriously underrated asset on your vehicle: the tow hitch! Many workers have equipment that can only be transported by a hitch, while others simply prefer to tow a trailer with their tools/mini digger etc. If your air compressor is taking up that spot on the hitch, you’ll need to make other compromises to get your equipment where it needs to be.
In some cases, business owners send out an extra vehicle and driver just to get all the right equipment in one spot. In others, favourite pieces of equipment are left behind or require extra trips to retrieve. When you mount your air compressor to the vehicle itself, you free up your hitch and improve your productivity.
One fantastic example of this improved productivity is with asphalt crack sealing, where cracks need to be blown out before they can be sealed. A truck-mounted air compressor can be used to blow the dirt out of the cracks, as the hitch pulls the asphalt applicator immediately behind.
Imagine this: you’ve just arrived at your next job only to realise it needs the air compressor you left behind. You have to actively plan for every trip with your tow-behind compressor, and decide whether it’s worth bringing along. What a hassle!
Alternative mobile air compressor systems have the compressor mounted to the vehicle itself, which means it goes everywhere the vehicle goes. If you need air, it’s there. You’ll never have to experience the frustration of needing the air compressor that’s halfway across town.
You probably already know that there’s more than just physical baggage with a tow-behind, and they carry the need for extra safety precautions everywhere they go. The hitch, taillights, and tyres all need to be checked frequently and, if any of these parts are failing, you’re not going anywhere until they’re fixed.
In addition, tow-behind air compressors make it harder for vehicles to stop quickly and safely. That means you need to reduce your speed whenever you’re towing your compressor, wasting valuable time that could be spent on the job or with your family. Throw in tow bar regulations, a larger blind spot, and the need to monitor the compressor itself, and you’ve got a lot of extra safety checks in your day.
And let’s not forget about thieves. Tow-behind compressors are often targeted by thieves because the units can be stolen in just a few minutes. By contrast, compressors that are mounted directly to a vehicle are significantly harder to take, while UNDERBONNET air compressor systems are practically impossible to steal.
When you stop towing your air and upgrade to a mounted air compressor, a lot of these safety concerns are instantly eliminated. Your compressor becomes a part of your vehicle or van, requiring fewer checks and precautions, and driving becomes safer.
Tow-behind air compressors require their own engine, in addition to the engine that’s included in the vehicle that’s doing the towing. That means two engines need to be maintained for every tow-behind compressor. This maintenance takes up valuable time and money that could be used elsewhere.
While some mobile air compressors require their own engine, many don’t. Recent air compressor innovation has been highly focused on utilising existing energy sources to power mobile air compressors. For example, petrol and diesel vehicle engines, transmissions, and PTOs that run hydraulics can all be used to power an air compressor.
Time is money. The faster you finish your work, the more time you have to wrap up your “to do” list, take on more jobs, or even just enjoy an extra long break or two. Tow-behind compressors take time to properly position, set up and use.
When you upgrade a tow-behind to an UNDERBONNET , HYDRAULIC or STANDALONE mobile compressor, you’ll be amazed at how quick and easy it is to get a job done. In some cases, the prep is as fast as flipping the “on” switch and grabbing the tool, while the job itself can be just as quick.
If you’d like more time in your day (and who wouldn’t), it might be time to give your tow-behind the boot.
Tow-behind air compressors are beasts. They’re notorious for being overweight monsters and they got that reputation for a reason… The Atlas Copco XAS 110 is a relatively small tow-behind compressor that can produce 110 CFM and weighs in at 499kg. By contrast, the Techni Systems VMAC VR70 provides similar air power to run a jack hammer and weighs about 74kg. That’s a huge difference! Choosing a lightweight air compressor means you’ll be able to add more tools and equipment to your truck, carry more materials, or take advantage of better fuel economy.
One of the best reasons to ditch a tow-behind air compressor is because there are much better options out there! Tow-behinds have the luxury of being overweight space-hogs, while other compressor styles have continually adapted to market demands with fresh innovations. For example, vehicle-mounted compressors can deliver more than enough air for light to medium duty applications, and do so in a system that’s significantly smaller, lighter and more compact than a tow-behind.
With modern compressor technology, you can enjoy all the benefits of having mobile air, while also freeing up cargo space, reducing gross vehicle weight, and working more efficiently.
Vehicle mounted compressors are the smart choice for people who:
At the end of the day, you deserve equipment that helps you get your job done quickly, easily, and safely. Tow-behind air compressors are necessary for some types of work, but there are a lot of downsides that you may have to endure. If you have the option to upgrade to a modern mobile air solution, then it’s time to ditch your tow-behind air compressor!
