From the super-portable models to the huge and stationary machines, air compressors come in a variety of sizes and shapes. Each machine is designed to serve a different purpose, so it is important to understand the differences between different makes and models before choosing one for your projects. When it comes to portable air compressors, the most popular models are the pancake type and the hotdog type ones.
Both models are perfect for small jobs around the home as well as professional workshops, but understanding the difference between them can be a concern for many. These portable air compressors often feature transport wheels and some sort of a carrying handle, and they are popular among DIY enthusiasts, carpenters, and handymen.
Pancake compressors derive their name from their low-profile pancake-shaped air tank design. The air compressor tank is around one to six gallons, but there are few exceptions with up to 8-gallon capacity. Typically, they are compact and weigh about 30 pounds a design that is not only easy to carry but also convenient to store.
Also, most are equipped with oil-free pumps to minimize the amount of maintenance required and also to allow for less mess around the workplace. Oil-less pancake air compressors are designed with user convenience in mind, and they are ideal for residential use.
One of the most desirable features of a pancake compressor is its stability, which makes it perfect for roofing projects and similar projects. Most pancake compressors deliver about 2 SCFM, so if you need a small compressor for home use or to take with you, a pancake compressor is an ideal tool for you. Ideally, you can use them in a range of projects including, running pneumatic brad nailers and inflating tires and balls.
Advantages of Pancake Compressor
We have already mentioned that pancake compressors are incredibly lightweight, but it is also important to note that they have a sturdy design that enables them to stay in a tip-top condition when placed in the trunk of your car. Also, you do not need to monitor the oil level now and then since most are oil-free, and the motor is not susceptible to overheating issues.
The noise level is also something worth noting, and generally, pancakes are considered a quiet option. Although they are not entirely silent, pancake compressors are a preference for those who need to stay focused and with minimal background noise.
Disadvantages of Pancake Compressor
As expected, there are several things you may not like about a pancake compressor, one of them being the small tank capacity. As stated, most have a 6-gallon tank, and this may not be sufficient to run all your pneumatic tools before the tank runs dry. The small capacity also implies that you’ll need to stop now and then to refill. However, this should not be a big issue if downtime is not much of a concern.
Also, their recovery time is not the best in the market, because they come with a small motor. The small motor tends to struggle to recompress air, and this reduces their efficiency and the amount of work you can cover in a day. Besides, a pancake compressor is not the most versatile power tool out there. If you need to operate heavy-duty appliances such as die grinders, you may need to invest in a more powerful air compressor.
What is a Hotdog Air Compressor?
A hotdog compressor, just like its pancake counterpart, is highly portable and lightweight, meaning it is also easy to carry, and it does not take too much space. However, hotdog compressors feature a bulky design, and they typically weigh more than pancake compressors. These compressors assume a tubular shape hence the name hot dog.
This shape can sometimes present storage challenges, although most models are compact enough to be packed away. Ensure to get one with carrying handle and additional accessories to help you move it around the job site.
The tank size range from 2 to 8 gallon, which means they provide more air volume pancake compressors and you can use them to run heavy-duty appliances including an angle grinder, air hammer, and impact driver. Many units come with oil-lubed pumps to maximum performance, but such models require a bit of regular maintenance. However, there are still oil-free models if you don’t want to be disturbed by maintenance hassle, but it is always a good idea to go for an oil-lubed design to ensure enhanced performance and long life.
Advantages of Hotdog Compressor
Fundamentally, a hotdog compressor is a highly portable machine that you can take with you to various job sites. These compressors come with carrying handles to enable you to move and lift as needed, like when you need to use it as an emergency pump for inflating your car’s tires.
Another competitive advantage that hotdog compressors have over pancake compressors is that they are capable of delivering more than 10 SCFM. This is more than enough to run most of your pneumatic tools from airbrushes to impact drives, and more.
Disadvantages of Hotdog Compressor
Perhaps one of the biggest downsides of hotdog compressors is that they tend to vibrate a lot when in use. However, choosing a machine fitted with rubber feet will help with help keep it in place and help reduce the vibrations substantially. In addition, placing a cloth underneath will help cushion the unit when it is running back and forth.
Secondly, they are typically noisy than pancake styles, so ensure to apply appropriate noise deafening techniques when using these tools. Thirdly, these machines are not the most powerful air compressor in the industry, so if you need to run powerful devices such as impact wrench, a hotdog compressor may not be a perfect choice.
That’s a Wrap
In the end, the choice of the air compressor between pancake and hotdog air compressors will depend on the type of work you will be engaged in or your individual needs. For example, if your primary consideration is efficiency, then you are better off with a hotdog air compressor. If, on the other hand, you are more concerned about a quiet operation and you are willing to spend more minutes on your home tasks, then you might want to consider investing in a pancake air compressor. However, if you want to get the most out of your compressor, it is always a good idea to invest in a larger air compressor.
