Rotary Air

A Brief History Of Air Compressors

Air compressors have been around for literally thousands of years. Now granted the devices the ancients used for compressing air bear little resemblance to the modern air compressor. However, the basic principle is the same and without the primitive air compressors, civilization would not have evolved as fast it has. One of the primary uses for compressed air was to increase the combustion in a furnace. The operator of a forge would use a bellows to blast compressed air into the furnace to stoke up the heat. This allowed ancient man to produce stronger and better metals for tools and weapons. Most people today would not equate a bellows as an air compressor, but that is exactly what it is. The blacksmith would pull apart the handles on the bellows and a check valve would allow fresh air to rush into the accordion like chamber. Then using muscles as the power source, the blacksmith would squeeze the handles together and the compressed air would shoot out the fitting on the end. Using this process it became possible to create a fire hot enough to smelt ores of copper, tin, lead and iron. Bellows are still used today in a variety of applications. The organ at your local church is probable powered by a bellows that is practically identical to one a thousand years ago. They even pop up in medical applications such as breathing machines in operation rooms.

It wasn't until later in history that it became possible to compress air using mechanical methods. In the past, only human and animal power was possible to power crude air compressors and this severely limited the utility of these primitive devices. With the industrial revolution, the mechanical air compressor was born. Engines running from steam power became the first method to power an air compressor. One of the first uses of a steam powered air compressor was in underwater diving equipment. This opened up whole new methods for under water exploration and even underwater construction. The compressed air could be pumped down to a diver and allow extended stays below surface. Compressed air was also much safer to use as a power source for early pneumatic tools and drills. For example, early rock drills were powered by steam. However, hot steam is far more hazardous than compressed air. A ruptured steam line can kill or seriously injure a worker while compressed air is relatively benign. Steam powered rock drills eventually gave way to drills powered by air compressors.

As the internal combustion engine gained popularity, they began to be used as a power source for air compressors. Gasoline engines are today commonly used in piston type air compressors. This would be a common air compressor you would find in your garage or on the back of a service truck. The gasoline engine drives a crankshaft and piston. As the piston moves into the downstroke postion, air flows into the cylinder on the low pressure end. When the upstroke begins, air moves into the high pressure. This action produces compressed air. In larger industrial applications, a rotary type air compressor is used. Rotary air compressors produce compressed air by turning a vaned rotor inside of a long enclosed chamber. As the engine spins the rotor, air is sucked inside the chamber. The air is then forced down the vanes into smaller and smaller areas. This action compresses the air and forces it out the other end. Rotary vane air compressors work very well in industrial applications because they are capable of producing large amounts of compressed air for extended periods of time.

The 2006-2011 World Outlook for New Stationary Rotary-Positive Air Compressors with Discharge Pressure of 50 P.s.i.g. or Less $795 The latent demand for new stationary rotary-positive air compressors with discharge pressure of 50 p.s.i.g. or less is not actual or historic sales. Nor is latent demand future sales. In fact, latent demand can be lower either lower or higher than actual sales if a market is inefficient (i.e., not representative of relatively competitive levels). Inefficiencies arise from a number of factors, including the lack of international openness, cultural barriers to consumption, regulations, and cartel-like behavior on the part of firms. In general, however, latent demand is typically larger than actual sales in a country market.

Yamaha Ytr-948Ffms Custom Series Rotary C Trumpet Silver $4935.99 The YTR-948FFMS Custom Series Rotary C Trumpet incorporates the newest design features with the tradition of classic European rotary trumpets. The 948FFMS features a .443-inch bore plus a new leadpipe, valve section and "Light Touch" rotor mechanism for a responsive instrument. The YTR-948FFMS Custom Series Rotary C Trumpet includes a case and mouthpiece and is available in silver (YTR-948FFMS) finish.The YTR-948FFMS Custom Series Rotary C Trumpet was designed by Brassmeister Thomas Lubitz at the Yamaha Frankfurt Atelier. The FFM in the model number stands for Frankfurt am Main. The YTR-948FFMS was developed with input from Markus Bebek, Associate Principal Trumpet of the Opera Frankfurt am Main.LeadpipeThe taper of the leadpipe on the rotary valve trumpet has the optimum taper for superb intonation and dark powerful tone.Hand-Hammered One-Piece BellA one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone. A hammered, gold brass bell produces a more broad and rich, yet perfectly-balanced tone with quick response and extra presence due to advanced manufacturing.Hand-Lapped Valves and SlidesHand-lapping rotary valves and slides ensure an absolutely perfect fit and seal between the valve and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.Pressure-Formed TubingPerfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.ToneThe tone of the YTR-948FFMS is softer and rounder than piston valve trumpets.
