Decoding the Duty Cycle Rating of Piston Compressors Selecting the correct air compressor for your application can be a complicated process. Before making a purchase, operators need to specify the quality and amount of air their application requires. Each compressor technology (rotary, piston, centrifugal, etc.) has an optimal flow output, so users should choose compressor technology based on the compressed airflow requirement of their application. Some compressors, like rotary screw and centrifugal, are designed to run continuously at full speed while maintaining peak airflow (defined in cubic feet per minute, or CFM). The motors and cooling systems of these compressors are engineered to run 100 percent of the time without overheating. However, this isn’t true for all compressors. Piston compressors do not have the cooling capabilities to run continuously for extended periods of time. Therefore, each piston compressor must have a specified flow output and pressure, as...

Splash and Pressure Lubrication in Piston Compressors Piston compressors  have been around for centuries. They can be either oil-injected or oil-free, depending on the application and end use. In oil-injected models, the oil typically serves three crucial purposes: cooling, sealing and lubricating. But not all oil-injected piston compressors lubricate components the same way. There are two common methods of lubricating the pump in piston compressors: splash and pressure lubrication. Splash lubrication In splash lubrication, oil is applied to the cylinders and pistons by rotating dippers on the connecting-rod bearing caps. Each time they rotate, the dippers pass through an oil-filled trough. After running through the oil trough, the dippers splash oil onto the cylinders and pistons to lubricate them. While splash lubrication is effective for smaller engines and pumps, it’s not a precise process. Parts of the pump may be insufficiently oiled or oiled too much. The ...

Using Compressed Air? Think again! We know this might sound strange from a guy who's all about compressed air... ... but did you ever wonder WHY and IF you really need to use compressed air? It might have been a very bad decision to make use of compressed air for your tools, machines, actuators, etc. Sure, some applications DEMAND compressed air. It's simply the only real option for it. And we know, compressed air and has many upsides: compressed air tools are very powerful they are safe to use can operate in very dirty environments are cheaper compared to their electrical counterparts can last a lifetime. I love all the benefits that using compressed air for your application brings.. but there is one very big downside.. Compressed air is EXPENSIVE. Very expensive. In fact, it's 7x - 8x more expensive compared to electricity. We talked about the cost of compressed air. And here's an example that shows exactly how and why using compressed...

VSD (Variable Speed / Frequency Drive) Compressors The energy savings were huge… of course. The pay-back time would be a few months, or days, or less.. for sure! Stop here! Yes, a VSD compressor can save huge amounts of energy (and thus money), but only if a propoer homework is one, make some calculations and use your common sense. [For those in the dark: a VSD or variable-speed compressor uses a frequency drive to match the compressor speed (and thus capacity) to the amount of compressed air needed. This as opposed to 'load-unload' machines that runs at a fixed speed but 'loads' and 'unloads' between a minimum and maximum pressure). And IF a VSD compressor is a good idea in your situation, buy the right size of VSD compressor. Here's when a VSD compressor will save you money: when it runs at less than 80% speed for most of the time and when it runs continuously (daily). In these cases, the cost-savings can be huge. Tens of thousands of dollars per year ...

3 Ways to Save Money On Compressed Air What if you knew that your compressed air system was completely optimized… running happily day after day. No more waste of money and electricity… Because let's face it: wasting thousands of dollars per year on electricity, without you knowing it, sucks. Want to optimize your compressed air system? It's impossible to share the complete step-by-step system in an email, but I can get you started on the right path. Compressed air optimization #1: Air leaks As discusses in our previous blog: fix those leaks! Compressed air leaks are the number one energy wasters! The biggest, most rewarding, leaks will be easy to find. For the smaller leaks, you might have to do some extra work, but it will pay off! But more importantly, once you fixed most of the leaks, put a system in place to continually check for and repair new compressed air leaks. You can also use some stealth tactics like dividing your compressed air network in zones and shutti...

Power and installation: For every horsepower, a compressor delivers 4-5 cfm (m3/hr), at 100 psi (7 bar) pressure . A 50 HP air compressor can produce up to 12 gallons / 45 liters of water per day (with only 8 running hours daily). Air receivers should be sized about 4 gallon capacity for each CFM of compressor capacity. That's 9 liters per m3/h in metric units. For example, a small 20 cfm compressor needs an 80 gallon air receiver. Costs and energy savings: On average, compressed air costs about 30 cents per 1000 cfm (1700 m3/hr). This depends on the size of the compressor and includes electricity, purchase price of compressor and maintenance costs. A 50 HP air compressor will cost you about 25.000 dollars in electricity cost per year (at 6.000 running hours per year). Every 2 psi (0.15 bar) of pressure drop in your system will cost you 1% extra in energy cost (this adds up quickly!!!) Pressure - Rule of Thumb Lowering Compressor Inlet Air Temp...

SmartAir Master Compressed air  management system Superior control solution with great energy saving potential Compressed air systems typically comprise of multiple compressors delivering air to a common distribution system. The combined capacity of those machines is generally greater than the maximum site demand. With CompAir's advanced demand responsive sequencer SmartAir Master, the efficiency of compressor stations with up to twelve compressors including downstream equipment can be maximised. Apart from the energy savings, the compressed air management system also contributes to decreased downtime, optimum performance, service and monitoring and ultimately leads to increased plant productivity. A profitable investment Up to 35% energy savings can be achieved by implementing a central SmartAir Master multi-compressor controller. Harmonises the workload of up to 12 fixed or regulated speed compressors Eliminates energy waste by tightening the network pressure ...
