How long does a VIAIR Compressor last?
When looking for compressors, you will come across a concept known as duty cycle. A duty cycle means the amount of time a compressor can operate before it needs to be cooled down. VIAIR states that its 400p air comopressors have been rated at 33 %. This means that a 400p VIAIR air compressor can run for 15 minutes and then you will need to cool it down for half an hour. The 450p VIAIR air compressors, with their 100 % duty cycle, can run for 60 minutes straight. However, this rating is for 100 psi at a standard temperature of 72 degrees Fahrenheit. If you go by the duty cycle methodology, your VIAIR air compressor can last for a long time. However, if you don’t allow the compressor to cool down, it won’t last long. On average, a VIAIR compressor can last for 10 to 15 years.
How do you use the VIAIR 400p?
A VIAR 400p portable air compressor can make your life easy but do several tasks efficiently. This compressor can easily fill 35-inch tires and due to its portability, you can easily carry it around. However, if you haven’t used a VIAR 400p compressor below, go through the instructions below:
Safety
As with other power and electrical equipment, you should always wear safety glasses before using a VIAIR 400p air compressor. Once you have the safety gear on, connect your hose to the valve and the power tool to the hose.
Start the Compressor
Before you start the compressor, ensure the pressure gauge switch is off. Plug the power cord in an electrical outlet. However, refrain from using an extension lead as this can cause the engine to overheat. If required, use an additional hose. Then, turn on the pressure gauge switch, this will enable the compressor to build pressure in the air tank. Keep the pressure gauge on until the pressure has reached the desired level. Once you start using the compressor, the pressure will decrease but the compressor automatically build the pressure. Set the psi specification in the compressor, you can do this by adjusting the regulator knob. However, try not to increase the psi pressure recommended by VIAR.
What is the Difference Between VIAIR 400p and VIAIR 450p?
The VIAIR 400p portable compressor is part of the company’s heavyweight class and comes with a 300 % duty cycle. On the other hand, the 450p VIAIR air compressor is part of the extreme series line and has a 100 % duty cycle. The 450p compressor edges out the 400p air compressor because of it 100 % duty cycle. The main difference between the two air compressors is speed, as 450p air compressors doesn’t take long to cool down. However, while the 450p VIAIR air compressor can run longer, it is technically slower than the 400p portable compressor. When these two compressors were tested on a car, it was concluded that the 400p compressor has a fill rate of 37 seconds on 35 inch tires. While the 400p is an air compressor for 35 inch tires and is undoubtedly faster per tire, you could run into a situation where the compressor needs to cool down for half an hour. Both 400p and 450p are worldclass compressors and, but the 450p is a more consistent compressor.
Do VIAIR Compressors need Oil?
No! VIAIR Compressors are oil-less, and you can mount these compressors in any direction you want to.
What Size Air Compressor is good for Inflating tires?
There are a few factors that you need to consider before using an air compressor for inflating tires:
PSI
This is the most important factor, and it is the maximum PSI rating of an air compressor. PSI stands for pounds per square inch and is a measurement of the amount of air an air compressor can offer. If the tire requires more air than what the compressor can offer, you won’t be able to inflate the tire with the compressor. The compressor will only be able to inflate the tire partially. For example, if your compressor works at a maximum pressure of 70 psi, and you use to fill a tire that requires 100 psi, you won’t be able to inflate the tire with the compressor. It is best to always use a compressor that has a maximum operating capacity of 10 psi or higher that the suggested tire pressure. So for instance, your tire requires 100 psi, but you should invest in a compressor that is 11o psi or higher.
CFM
CFM stands for cubic feet per minute and is an important factor when measuring the CFM rating of a compressor. The CFM rating typically impacts how efficiently and quickly you can fill a tire. However, you should remember that CFM is always measured in the context of the air pressure. For instance, if a compressor can offer 1 CFM at 100 psi, it will probably be able to offer 2 CFM at 50 psi. This is necessary to understand because you shouldn’t be going lower than 1 CFM at the required tire pressure, unless you don’t mind doing fill times with tires.
Duty Cycle
An air compressor duty cycle rating is the recommended time a pump should be turned on during a given usage duty cycle. For instance a duty cycle rating of 50 % means that you shouldn’t let the pump run for more than half time you are using the air compressor. This means that the pump should rest for 1 minute after being in operation for a minute.
Hose Length
Another thing you need to consider is air hose and power cord length. Generally, experts say that it is best to avoid extension cords for air compressors, as they can degrade the motor quality and can cause reproductive harm. It is always better to use a hose that is lengthy, even though this can lead to a loss in power. Since it is not always convenient to bring the tires to the air compressor, you should invest in a portable compressor kit that you can take to the tires.
Size of the Tank
The size of the compressor’s tank will make a differnce in the fill rates and dictate how long your compressor can operate. If you are topping off a tire or two tires, a 1-gallon compressor tank should get the job done for you. However, if you are filling a tire that is empty, it will take multiple fill cycles to get the tired filled completely. Generally, the larger the compressor tank, the less fill times it requires. Portable compressors that have a 3-gallon and 6-gallon tank, are typically better at filling empty tires.
Do I need an air compressor for Off Roading?
Do you require an air compressor for off roading? Yes! reducing the amount of air in your tires while driving off-road is one of the easiest way to improve ride comfort and traction. Off road enthusiasts worldwide recommend carrying an air compressor or a tire inflator so that you can reinflate tires once you leave the trail.
What Size Air Compressor do I need for Bicycle Tires?
A cheap compressor should do the trick for you when it comes to filling the bicycle tires. However, there are a few elements that you should consider before buying an air compressor for your bicycle tires. The more expensive air compressors come with a big tank, and they offer more filling options than cheap air compressors who can just do basic tasks. The increased capacity of air compressors means that they can offer more air before the pressure reduces. That being said, it is not important to have a large air compressor when filling bicycle tires because bicycles usually have small tires. The minimum requirement for bicycle tires is a 3-gallon tank compressor or a low cost 6-gallon tank compressor.
What is the most Powerful 12 volt Air Compressor?
