About Oil Less Air Compressors

Portable air compressors vary by size and power level, and there are a few different models available from which to choose depending on the tools you will use. Be sure to check the power requirements of your tools to ensure that you purchase a model that has sufficient power to run your strongest tool. Regardless of the compressor you purchase, it is always very important to follow the safety precautions including safety goggles, protective clothing and proper footwear. Portable rotary screw compressors are one of the more commonly used compressors. They range from 65 to 1,600 cubic feet per minute, with pressure ratings ranging from 100 to 350 PSI. As discussed above, the compressor you need depends on your tools and the required power level. Contractors often use 185 CFM because they are able to power two tools simultaneously. One benefit to this compressor is its suitability for both the lighter and heavy duty jobs. The truck mounted compressor is an oil less air compressor and ca...

Compressed Air Leaking? Is It The Valve Or Is It The Cylinder?

Reducing air leaks in your plant can save thousands of dollars annually. Compressed air is one of the most costly forms of energy you can use in your plant, of course, it's one of the most versatile, fast and strong too. When it's "quiet time" in the plant, wander around the machinery and listen. You will often hear the gentle (or perhaps not so gentle) hissing of air escaping from the exhaust port of your air valves. The sound of compressed air "chewing up your dollars" as it wafts to atmosphere can be muted if your air valves have mufflers in the exhaust ports, but nevertheless, it can be heard. Also, there are commercially available ultra-sonic compressed air leak detectors on the market. If your plant doesn't have a "quiet time", which would enable you to actually hear the leaks yourself, investing in an ultrasonic leak detector can bring substantial payback in energy savings. Usually you'll have one air valve connected to one air c...

How Air Duct Cleaning Improves Air Quality

Air duct cleaning is the term commonly applied to the work performed by professional HVAC cleaning contractors. It’s a service that is necessary in order to provide clean air throughout commercial buildings and homes. In business environments air duct cleaning is an important way to insure the comfort of employees for better work performance. It is important to clean air ducts occasionally to insure the safety and security of employees in the work place. Especially in cases where there is a need to remove harmful fumes. Many believe air duct cleaning is as important as having clean running water. Buildings that don't have proper working air ducts tend to be very muggy and seem very damp. Air duct cleaning is one task that when performed, can help keep the indoor air safe and clean for residents to breathe. Home owners are beginning to realize air duct cleaning is an important part of home maintenance and is essential to keeping their indoor air healthy. Home owners should be aware...

How to Buy a Refrigerated Compressed Air Dryer

Many customers are often confused as to which kind of dryer for compressed air would work well for them. While some people prefer high-end brands, others may want to opt for more cost-effective solutions. No matter what your prerogative maybe you should consider the following aspects before purchasing any air dryer system. Reputation of the brand First and foremost, no matter which kind of dryer mechanism you are looking for, make sure the manufacturer enjoys a good reputation in the market. You may end up purchasing a lower end model at a cheaper rate but the downside to this is that your maintenance and repair costs may go up in the long term. Always select a brand, which is well versed with the compressed gas treatment domain. Most manufacturers of compressed air dryer mechanisms should enjoy a good level of customer service not just before the sale but also post sales as that is when it counts the most. Feature sets Once you have zeroed in on a particular brand, you want to explore...

Compressed Air Filters

Compressed air filters are widely used in the industrial arena. They are used to remove water, oil, oil vapor, dirt and other contamination from a compressed air supply. Compressed air filters are used to control and cool various forms of industrial instruments. A pneumatically operated machine suffers serious effects caused by dirt particles, oil carryover and moisture. In most of the applications, contamination of the air supply could lead to serious performance degradation and most likely will increase the maintenance cost in terms of repairs. The result of this is that productive time is lost. The only way to cut down the costs and increase the performance is to properly maintain compressed air filters. There are different types of compressed air filters. All of them are built in a way to remove the oil and other contamination from the air supply. Some have special features that make them more effective in specific applications. Coalescing oil removal filters are able to remove oil...

How to Tell When Your Compressor Needs an Air Dryer

Ask a Question: Can water or moisture be damaging my compressed air system? Answer: Absolutely! Water corrodes pipes, valves, machinery controls. None of this is good. When controls malfunction, production can stop or product can be impaired and all this costs you time and money. Water in Aerosol or Vapor form is more difficult to remove and requires the use of a Compressed Air Dryer. Ask a Question: How does water or moisture get into my compressed air? Answer: Through your Compressor inlet. Water vapor (humidity-moisture) enters the air system through the air compressor inlet air filter. The air compressor sucks in approximately 7 cubic feet of atmospheric air at 0 psig, and that volume of air is compressed into 1 cubic feet of air at 100 psig. The water vapor (humidity-moisture) that was in the 7 cubic feet of atmospheric air is now compressed into 1 cubic feet of compressed air. There are 3 forms of water in compressed air: -Liquid water -Aerosol (mist) -Vapor (gas) Any of these fo...

Compressed Air Dryers and Refrigerated Air Dryers

Compressed air dryers are being used in different industries. They are needed to ensure that the operations of machines are performing perfectly. However, there are so many of them in the market right now that coming up with the most ideal choice will always be very hard. Nevertheless, there are the ones that stand out. When you want to buy compressed air dryers or refrigerated air dryers, you may want to choose any of the following: Cycling Refrigerated Air Dryers. If you are looking for a device that will allow you to save as much as a thousand dollars for every piece of equipment that you buy per year, then the best option will be the cycling refrigerated air dryer. This one is able to maintain its dew point, even if it is performing below its design capacity. Since the total cost of energy will be dependent on the amount of air that is dried, you know that you are able to maximize on the performance and thus are able to save with these compressed air dryers. High Inlet Temperature ...

Tips to Reduce Compressed Air System Pressure Drops

Ask a Question: What causes pressure drops in my compressed air system and how can I reduce them? Answer: Pressure drop can become a compressed air system problem that steals production time and money. What causes pressure drops? Any type of obstruction, restriction, or roughness in the system will cause resistance to air flow and cause pressure drop. In the distribution system, the highest pressure drops usually are found at the points-of-use, including undersized or leaking hoses, tubes, disconnects, filters, regulators and lubricators (FRLs). On the supply side of the system, air/lubricant separators, aftercoolers, moisture separators, dryers and filters can be the main items causing significant pressure drops. The maximum pressure drop from the supply side to the points-of-use will occur when the compressed air flow rate and temperature are highest. Your Compressed Air System components should be selected based upon these conditions and the manufacturer of each component should b...
