Air Compressor Blowers
| Jeff McEachran
Car owners have differing theories about how to care for their vehicles. Some insist that the focus should be on washing the windshield and windows daily with soap to ensure clear vision while driving. Others think washing the windows too often can reduce transparency. Regardless, drivers have learned to do what they feel works.
Another hypothesis that leaves car owners needing help with what to do is the topic of drying their cars after a wash. Many thought that since the car would be outside, making a conscious effort to dry it was unnecessary. However, drying is considered a big part of the car wash process. It does not only help to avoid water spots and streaks from settling on your vehicle after it dries on its own. Drying your car after a wash also protects the delicate painting on your vehicle's body and should already be a part of your wash routine.
This article will shed more light on using air compressor blowers to dry your car effectively.
Difference Between an Air Compressor & an Air Blower
You might be familiar with car air compressor blowers for drying cars, especially if you judiciously wash and dry your vehicle appropriately. Air compressors and air blowers serve the same purpose of drying after washing, but there are fundamental differences between the two.
The pressure ratio is the primary feature that differentiates an air compressor from an air blower. The air compressor blower contains air in its compact form, and because of this compressed air, its particles are under a lot more pressure. This compression makes the air in them denser and the pressure ratio higher. The opposite is the case for the air blower system. The air contained in it is uncompressed, and it is lighter. Hence, they have less pressure ratio when compared to the air compressor.
What is an Air Compressor
The air compressor reduces the standard volume of atmospheric air and packs it in a smaller space. The process involves storing the compacted air inside a pressurized chamber until you need to eject a focused airstream. This system is more appropriate for manufacturing due to the intermittent burst of air operating at a high-pressure to-volume ratio.
The air compressor operates in two main ways:
When the screws or pistons in the air compressor decrease the air volume in the chamber, it uses positive displacement to convert power from electric motors or gasoline engines to pressurized air.
Here the air in the chamber accelerates or decelerates by centrifugal force. It takes air from the atmosphere and compresses it with a diffuser and an impeller. The centrifugal air compressors run at a higher speed than blowers to create higher pressure rises for larger applications.
Benefits of The Air Compressor
Adaptable working conditions:
With either fixed or variable volumes of compressed air, you can meet the need of various equipment making the air compressor more valid for industrial use. The flexible control option allows for the necessary adjustment based on the environmental conditions, including extreme weather conditions like high temperatures and humid levels.
You can direct or aim the airflow from the compressor and control it based on the situation. For cleaning, it supplies concentrated bursts to target areas. The dense nature of the air makes drying cars easier and faster. If you want a quick dry for your newly washed cars, an air compressor is what you need.
Compared to blowers, it’s pretty expensive to operate the electric costs of an air compressor over time. Therefore, several brands offer energy-efficient units with variable speed drive to decrease energy usage.
What is an Air Blower
Air blowers apply moderate pressure increases to move large volumes of air. Compared to air compressors, the BLO air blowers operate at a lower pressure-to-volume ratio to allow continuous and unsupervised use. In classifying the blower as centrifugal or positive displacement, the air blowers can be either since all models of BLO car blow dryers apply reliable low-pressure, high-volume air.
It functions as rotators, impellers, or fan blades that suck and compress air in the device’s suction side, where it releases in a high-speed stream. In the centrifugal blower, the air volume remains constant as it displaces from one end to another. As the propeller in the blower rotates using centrifugal force, the positive displacement accelerates the air outwards with flow rate and pressure as dependent variables.
Benefits of The Air Blower
Air blowers are powerful and cost-effective, making them more suited for prolonged use.
Air blowers can function in various situations and industries since it requires no regular monitoring or human supervision. It’s also self-sufficient, beneficial, effective, versatile, and requires lesser maintenance.
With a steady airflow, the air blowers can move large quantities of air for a longer time, moving water off your car paintwork and ensuring it maintains its sparkle.
Affordable and Accessible:
Air blowers are cheaper to use than air compressors. The cost of purchasing, maintaining, and utilizing air blowers is pocket-friendly, which is why they can be found easily in most car washes. They are also commonly purchased from physical and online automobile shops, like BLO dryers.
What is The Difference Between a Pump & a Blower?
A pump pushes incompressible fluids like water and oil at high pressure from one point to another, mainly for circulation. The blower is a duct fan to blow air and other compressible substances at high speed, driving dust, scraps, smoke residues, and water away. In reverse, the blower is a vacuum cleaner.
The compressor differs from other devices as it has a storage tank to compress fluids in an enclosed place. The compressed air is from the tank, but when the pressurized gas drops, the compressor refills the tank. Both air compressors and blowers are useful for industrial purposes in most car wash outlets.
What is the best CFM for an Air Compressor?
Air compressors with lower Cubic feet per minute (CFM) work better for minor duties such as tire inflation. The primary use of the ones with higher CFM is for industrial functions. On average, you should consider between 30 to 40 CFM for an air compressor, especially if you are not purchasing one for industrial use.
How many CFM is a 7.5 HP Air Compressor?
A 7.5HP Two stage air compressor has a CFM of 31 at 100PSI
