Air Compressor Buyer's Guide
The Right Air Compressor for the Job
There's an air compressor to meet any budget, whether you're inflating a bed, repainting your car or installing crown molding.
Air compressors are extremely useful machines; they feature a powerful electric motor that compresses air into a steel tank. When the compressed air is unleashed, the pressure allows for a burst of air capable of powering many different pneumatic tools.
When it comes to a purchase as large as an industrial air compressor, you need a unit that meets all your requirements. There are two types to choose from: two-stage compressors & rotary screw compressors. Your first job is making sure which type of compressor you will need.
Two Stage Air Compressors
Two-stage air compressors are found in many garages and manufacturing facilities. Two-stage compressors are used to power air tools, such as air hammers, die grinders, impact wrenches, and nail guns. Most have enough power to run several air tools at once.
These compressors are powered by either gas or electricity, although most are electric. Using two pistons, 2-stage units compress the air twice, delivering more air power than smaller compressors.
Energy costs for two-stage units can begin to cost a lot of money, so keep that in mind when purchasing. Two-stage compressors can usually create up to about 90 CFM (Cubic Feet per Minute).
Rotary Screw Air Compressors
Rotary screw compressors are the largest, most powerful compressors on the market. If you have greater than a 60% duty-cycle need, then choose a rotary air compressor.
You will find these in the most professional garages and factories where a large amount of compressed air is required nonstop. They often provide compressed air for precision tasks such as powder-coating or sand-blasting. Rotary screw compressors are powered by two counter-rotating screws (rotors) which compress air as it is forced through the grooves of the screws.
Exceptionally efficient and surprisingly quiet, rotary screw compressors are the most technologically advanced units in the compressor market. The energy consumption is extremely low despite the great power of rotary compressors. This is due to the great amount of pressure that the rotary screw system can produce, with less work to create that pressure.
Rotary Screw Air Compressor Energy Efficiency
One of the first things you'll notice about a rotary screw air compressor is the price tag. The upfront cost is higher than other types of air compressors, but, the investment will pay off.
With reciprocating air compressors, the cost of energy required to run it can exceed the purchase price in only one year. However, with rotary screw compressors, 10 years of energy costs will roughly amount to 70% of the original purchase price.
These air compressors are built to run constantly for at least a decade. Rotary screw air compressors are designed to handle the demands of the most high-volume professional garages, factories and other industrial settings.
Because of their reliability, power, and longevity, rotary screw compressors are found on oil rigs and in amusement parks, powering roller coasters and fountains.
Garage Equipment Supply offers a variety of air compressors, vertical or horizontal and powered with gas or electricity. Choose the air compressor that will answer the needs of your professional shop or your home garage, whether it's a heavy-duty, tank-mounted floor model or a convenient portable compressor you can wheel from place to place. Accessories include compression testing kits and moisture minders.

Experience the pure power of BendPak Air Compressors
BendPak air compressors have a well-earned reputation for high performance and dependability. When you're concentrating on a project, you shouldn't have to worry about the temperature or moisture inside your air compressor; you need a unit that works just as hard as you do. BendPak's highly efficient TRI-MAX™ line of air compressors are perfect air-pumping power-houses that feature rugged cast-iron construction, reliable belt-drive Baldor™ motors, high-quality Manchester Tanks, true copper piping for cooler operation, pressure control and extra large pumps. BendPak offers a variety of motor options for their TRI-MAX™ air compressors, such as one or three phase, 50 Hz or 60 Hz and 5 horsepower or 7-1/2 horsepower.
But what about the moisture and air temperature?
BendPak TRI-MAX™ air compressors directly address this problem with larger pistons operating at lower speeds. Lower rotations per minute directly result in lower operating temperatures, but thanks to the larger piston size, you don't have to sacrifice any performance. With lower a temperature comes much less moisture, ensuring your TRI-MAX™ has a long and happy existence in your shop or garage. Whatever your high-pressure air needs might be, BendPak has exactly what you need.
