When designing an air compressor or purchasing a pre-designed system for your work, it’s important to consider where your compressor air intake is located because the location has a direct impact on the compressor’s performance. There are three important factors to consider with the inlet location: Particulates in the air (dust which can plug filters) […]
Water is a challenge in every air compressor system. As air is compressed, water is brought into the air stream. During cooling, that water condenses and is mixed with the compressed air that’s delivered to your tool or application. Some water is okay for most applications but too much water can be a problem. That’s […]
VMAC recently received a message from a process engineer in London who had a great question after reading our How to Work Out ‘Time To Fill’ Type Questions Using Simple Logic article. The process engineer asked: “I was wondering if you have a similar calculation that you could share for “How to Calculate the Depressurization […]
Heaterless Type (Pressure Swing Dryers) Dual tower desiccant air dryers are used to produce dewpoint temperatures below the freezing point of water, as well as reduce the moisture content of compressed air used in critical process applications. Typical dewpoints produced by these types of dryers are -40° F to -100° F, although lower dewpoints are […]
Small CFM gas driven air compressors won’t perform as well at 5,000 feet of elevation as they do at sea level. They may fail, bog down, or supply less air power. But why is this? It all comes down to the physics of gas combustion engines.
The air compressor industry loves to use acronyms, especially when measuring airflow and air consumption. Two common acronyms, representing measurements, are ACFM and SCFM. CFM—or Cubic Feet per Minute—is an important metrics when choosing an air compressor and related pneumatic equipment. Pneumatic tools and equipment require a specific minimum air mass, or CFM, to perform […]
The difference between PSI and CFM are what they measure. PSI measures pressure, while CFM measures volume. PSI and CFM are often used as performance specifications for air compressors. Together, they indicate the maximum air volume and pressure produced by an air compressor to power air tools. To better understand the difference between PSI and […]
If you’ve determined what size of compressor you need and the engine requirements to power that compressor the next important step is to ensure that the combination is going to operate optimally in your working environment. In the case of mobile compressors this may include high altitudes, dirty environments and large ambient air temperature fluctuations. […]
Say you have an air tank or some other suitably pressure rated vessel and you want to figure out how long it will take to bring the pressure up to a certain level using a compressor of known capacity (CFM) and you want to do it using common sense, not a lot of formulas.
Anyone who has had to use a compressor at a high altitude knows how frustrating it can be. Compressor performance is degraded and it can take a lot longer to complete tasks. People who move to or work in areas that are at a higher altitude are often surprised when their compressor seems to be […]
