This question is hard to answer without knowing your budget or expectations but we figured we could help you answer that question for yourself by reading more down below. To put it simply the big difference between single stage and two stage compressor is the number of times the air is compressed within the pressure side of the compressor head.

A single stage compressor only runs it through one time and then puts it in the tank while a two stage you guessed it!

Within a single stage air compressor the air is drawn into a cylinder and is compressed at PSI and then delivered to the storage tank attached to the compressor. Whereas in facilities that operate with two or more shifts and where the operating costs are quite high, the savings that can be gleaned from a dual-stage compressor are impressive.

As those working in the manufacturing sector will be aware, compressed air is used in various applications and plays an invaluable role in any operation.

It can be used in packaging, product transportation and storage, filling, capping, cooling, spraying and cleaning and even fermentation and aeration. Particularly as operators must meet the air quality standard that is specified in ISO Class O. Sometimes this involves heat-branding the logo onto the glass. In most cases, pneumatic robotic arms apply a sticker to the bottle. Packaging: After the bottles are filled, sealed and labeled, they are ready to be packaged and shipped.

Some drinks are grouped together in packs of four or six, while others are sold separately. At beverage plants, air-powered robotic arms safely and neatly package each bottle into a box for easy delivery. A similar process happens in factories the package foods in cans and jars. Dual-stage compressors are ideal for the processes employed along the conveyor systems at food and beverage processing plants.

Food assembly and packaging could either need a single- or multi-stage compressor. It depends on the scope and magnitude of the processes. If you are producing foods inside a bakery or the in-house kitchen of a supermarket, you can probably accomplish everything with a one-stage air compressor.

For mass preparation and packaging in a factory, you would need a two-stage. Either way, compressed air is typically used to drive the following processes in the food industry:.

Mixing: Compressed-air tools are often used to blend the ingredients of various baked goods, such as breads, pastries, cakes and cookies. Once the ingredients are perfectly measured and added for each batch, the mixture is readied in a large bowl with pneumatic blending equipment. This way, bakers can produce these goods in much larger quantities than would otherwise be possible if the mixing relied on human hands.

Powdering: For mass-produced powdered doughnuts and cookies, air-powered equipment usually does the powdering. The impact and radius of applied air are enough to cover the entire surface of each edible item in one application and also light enough to prevent damage. Frosting: For cakes and other frosted treats, air-powered tools apply the icing. Air-powered tools also inject fillings such as cream or jelly into pastries.

Chopping: Pneumatic tools typically cut chopped or sliced foods. Potato chips, for example, are cut uniformly from raw potatoes. In factories, machine-peeled potatoes pass through conveyors where they are sliced with precision, sometimes with specially designed cutting tools that give certain potato chips their ridges.

After being fried, the slices are dried with compressed air and flavor-coated with pneumatic equipment. Cooling: Air-powered tools cool baked or fried foods to bring them back to room temperature. This reduces the cooling time so foods can be packaged more quickly.

Without the aid of air-powered cooling, some of these heated foods could take up to an hour to cool down to a temperature suitable for packaging. Cleaning: Pneumatic blowing tools clean food and beverage containers before packaging.

Containers on a conveyor system receive a blast of air to remove dirt, moisture or air-bound impurities that may have stuck to the interior surfaces. Nitrogen : For certain packaged foods, pneumatic nitrogen blowers pump nitrogen into the package before sealing to prevent the contents from being crushed.

In a bakery, single-stage air compressors are ideal for the air-powered process that food preparation would normally require. For mass-produced foods, factories need a dual-stage compressor to meet the higher demands of industrial machinery. For aircraft, tanks and other large pieces of equipment, air-powered machines are used in all stages of assembly. As with any factory production, you need a dual-stage compressor to generate the air power needed for the machinery at hand.

So how does a two-stage compressor work in aircraft and artillery construction? It does so in the following ways:. Cutting: The parts that comprise an airplane, jet or rocket must first be molded from raw metals and cut into finished shapes. These steps are conducted along large conveyor systems. First, the raw metals are cut into shapes with specific dimensions. Then, the parts are formed inside molding cavities.

These parts are then sent along for polishing and further preparation. A similar set of steps is employed for land vehicles and artillery. Such steps generally require high-powered dual-stage air compressors.
