Most varieties of air compressors can be found in as ‘Oil lubed’ and ‘Oil-less’ variants. Oil lubed means these Membrane Compressor have their internal mechanical system that produce the vacuum and pressure have a synthetic or semi-synthetic lubricants greasing the ingredients, etc. Whereas, Oil-less designs have seen more specialized development through the years. Nevertheless, these are fairly expensive, much louder and last for a shorter span of time as compared to Oil-lubed models. In spite of, the Oil-less models are known for delivering considerably better quality air and higher compression rates measured compared to the amount of energy required for operating them.
Uses of Air Compressors
Air compressors can be applied for everything. In fact, you may even invent something or some idea, which requires their use. For e.g., scuba divers, are now using these for breathing underwater. They carry air tanks (for oxygen) along with them when diving into deep ends in the oceans or even while diving for extended periods once they usually do not want to come up for the surface frequently for air. Even researchers, science enthusiasts or environmentalists going out towards the seas or oceans require them for filling up their air tanks to use underwater. It may be noted that such models are usually oil-lubed as they need to last longer and just small quantities of air is needed while filling air tanks.
Another range of equipment – air conditioners – is founded on this mechanism. Inside an Air Conditioner, the cooling agent (usually an inert gas) that absorbs heat from the air drawn in is pumped through a fine mesh of pipes. A Oxygen Compressor, typically runs this gas through these cooling fins. Without compressing and forcing this cooling agent, there could be no loss of heat and therefore, the cooling effect in the room or area would not take place. This is the absorption of heat and blowing it away from the room, which results in a cooler place.
Several other industries have adopted and, in fact, designed several hand tools, machinery and even robotics tools aided by air compressors. For e.g.:
– Nail guns for securing planks of wood or even affixing objects to walls etc.
– Jackhammers or pneumatic hammers for breaking apart hard materials like roads walls or other structure produced by brick and cement, etc.
– An engine may require Nitrogen Generator for cooling and heating its high-performance systems
– Specially engineered models will also be found in large power plants for delivering energy to huge machinery
Before choosing an air compressor, determine the kind of application in which is it intended. Whether or not this will be used intermittently or be kept running continuously at a time? A two-stage air compressor model first draws in air, then compresses it. This results in improved air flow and pressure. This also provides storing greater level of air, whilst reducing the amount of heat generated from the air compressor. Two stage models, thus, are recognized to possess a far greater shelf life than other models. Moreover, a zpjqpr mechanism model is best suited for intermittent use and rotary screw compressors for continuous use. Centrifugal compressors are large engines, created for power plants and high industrial units and hence, are not suited for or financially feasible for small-scale tasks.
