Rotary Screw Basics

There are many types of air compressors.  You need to evaluate your purpose before you decide if a rotary screw air compressor is what you need.  Air compressors are used to power small tools like automotive ratchets and construction nail guns.  Large Air compressors like rotary screw or centrifugal air compressors are used for industrial applications and can power a whole factory. If you need a steady flow of air to power your equipment without interruption rotary screw is for you.  Rotary compressors can provide a source of power to drive punching and stamping machines.  Compressed air can also power robotic equipment. Sandblasters and paint sprayers use the air directly.  A steady flow of air pressure is critical in a paint spraying application. Gas powered rotary air compressors do not have pistons.  They have two twin screws next to each other that push the air to higher levels.  Most rotary […]

Overview of Reciprocating Air Compressors

Air compressors explained quite simply, is a machine that moves the surrounding air into the machine and reduce its volume thereby producing pressure. The air, when released from the chamber, is then emitted forcefully out of the machine serving its main purpose. Some of the major purposes of air compressors would include supplying air for divers who are carrying oxygen tanks with them; providing the necessary pressure for common household tools that are pressure driven such as screw and bolt drivers, nail guns, and etc.; navigating air currents for centralized air-conditioning; or just simply filling your automobile tires. Reciprocating air compressor
 This type of compressor belongs to the positive displacement category as do rotary screw compressors and the vane compressors. It uses pistons in order to take in surrounding air and pushes it inward into the machine’s chamber and accumulating more air particles packed into a very small volume. One […]

High Pressure Compressors – What You Need to Know

As compressors proliferate throughout business and consumer use the demand for high pressure compressors has skyrocketed. Pressure is measured in pounds per square inch (psi or psig). The usage of one air compressor will vary according to the amount of pressure it is capable of exerting. The household air compressor that is used to inflate bike tires will have lesser capacity compared to dental air compressors and industrial compressors that often need a high pressure to perform the job required. Big corporations make use of the high pressure compressor to power their huge machines and manufacturing equipment etc. With insufficient pressure, the big machines would come to halt early or just does not function at all. This high pressure units are also used for compressing breathing equipment like diving oxygen tanks and those that are delivered and used in hospitals. In this type, a specialized filtration system is made available […]

Dental Air Compressors

Dental air compressor is now used as the primary tool in any dental clinic worldwide! The compressor is the main tool in the dental chair and powers the lift to adjust the height and position of the dental chair. And that’s not all. The tool the dentist uses to “blow” air into your mouth to dry the tooth’s surface is powered by an air compressor.  Further let’s not forget the spinning tool used when grinding a surface for a dental veneer, drilling for a cavity or adding polish to your teeth after a cleaning.  All that is powered by the dental air compressor. Even the saliva ejector is reliant on this technology. Most dental tools (if not electric) rely on air pressure to function properly. Dental air compressors these days use the oil free type so that no oil vapor goes into the dental patient which could possibly pose as […]

Pros and Cons of Gas Air Compressors

Gas air compressor or gasoline powered air compressors are those mentioned that require gasoline in the small generator-like component of the machine. The fuel (in this case gasoline) is burned much like those on car engines and the combustion produces energy which is then converted into mechanical energy that turns the rotors, fans, vanes etc. inward the machine, locks the air passageway (thus trapping the air), and finally accumulating and storing the air, decreasing its volume and increasing the pressure within the tank. Advantages: Gas air compressors come in handy most especially during power interruptions, on a construction site or when a gas air compressor is needed because electricity access is either not available or insufficient. Disadvantages: The down side about this is that gasoline can become really expensive and would largely depend on the economic supply and demand. When prices for gasoline rises, so does the cost of operation.  […]

Tips on Choosing a Reciprocating Air Compressor

Reciprocating Air Compressors are commonly known as piston driven compressors. They are generally smaller and portable, a popular style for contractors. Larger units are available for industrial use and are less expensive than rotary screw compressors, but keep in mind they are noisier and vibrate more. How they work The compression element in a reciprocating air compressor is a piston inside a cylinder driven by a crankshaft. They are positive displacement machines, this means they increase air pressure by reducing volume. The motor (electric or gas) powers the crankshaft to move the piston up and down. The compressed air is pushed into a high pressure holding tank. A one way check valve prevents the air from coming back into the cylinder. The air is now ready for use. Set the regulator to the amount of pressure you need for your particular application. Most power tools will have the PSI requirement […]

Advantages and Disadvantages of Remanufactured Compressors

Like many machines, air compressors too undergo wear and tear. It “ages” and depreciates according to how often it is used and the care and maintenance that it is afforded. But even with the fullest amount of caring, the machine will eventually break down and have its parts broken or malfunction. More often than not, when this happens, that machine will surely be bound for the junk yard and replaced with new ones. Well, that is way faster than trying to replace the damaged parts and finding the right individual to do it for you. But do you know that remanufactured compressors provide the same power that the new ones or the second hand compressors do? See Used Dessicant Dryers Here Remanufactured compressors are those compressors that previously broke down because of damaged parts or malfunctioning units. The defective parts are replaced with new ones, the unit cleaned and refurbished. […]

Tips on Buying a Used Industrial Air Compressor

Are you in the market for a used industrial air compressor? If so, you already know the benefits of buying used instead of new. Often people sell their used compressor not because anything is wrong with it, but because they have outgrown the particular model and require something with a bit more power. This is highly beneficial to you as you can generally pick up a solid air compressor at a fraction of the cost. Advantages aside, there are a few key considerations you should keep in mind when buying a used industrial air compressor. Tool Requirements An air compressor, whether new or used, is only an asset if it can power all of your tools properly. So the first thing you need to make sure of is if the compressor you’re interested in can power the tools you currently have, and any you think you might acquire in the […]
