Who Are We?
CompressorQuote.com is an online network of quality compressed air equipment dealers. The site is setup to ensure that you not only have access to the latest and most appropriate air compressor units available but that you also get this access at an affordable price-point.
Furthermore, by utilizing CompressorQuote.com, you gain access to this professional network for related needs such as application questions, maintenance and repair concerns and even installation needs and questions. So where does the air compressor equipment offered on this site come from?
Professional dealers are often asked to install new air compressors and related equipment on sites that already have equipment but where the existing unit may be undersized for the application.
Consequently, these dealers are left with a perfectly good and serviceable air compressor and related equipment that can be re-purposed for other applications.
The types and brands of compressors that come available at any given time varies. Some of the more recognized air compressor brands include those such as Ingersoll Rand, Doosan, Atlas Copco and Kaeser, among others.
Among some of the different types of compressors that are available through this online network include a mix of the following types of units:
Towable Air Compressors
Towable air compressors are vital for worksites that do not have their own power onsite yet or that are not conducive to portable compressor use for whatever reason.
These air compressors are mobile, easily serviced and come in a range of air capacities measured in Cubic Feet Per Minute or CFM.
Rotary Screw Air Compressors
These air compressors are fixed units that are meant to be permanently installed. Rotary screw air compressors have a set of helical screws that are embedded within in an oil lubricant which acts as a hydraulic seal that transfers more effectively the mechanical energy between the screws.
These vary in size according to horsepower with lower horsepower units being belt-driven and higher horsepower units being gear driven.
Reciprocating Air Compressors
This type of air compressor unit utilizes what is referred to as a positive displacement mechanism. This air compressor relies on a traditional piston-driven motor that compresses the air and then stores it in an attached storage tank.
These units are portable although limited in size. Air compressors have a wide industrial application across a range of different industries and occupations. Selecting the right one is critical to productivity. However, selecting the most cost-effective solution is also important.
Those companies that require the use of an air compressor often also require the use of an air dryer. Natural air contains moisture which must be removed in some fashion during compression within an air compressor. Air dryers are elaborate mechanisms that remove the moisture from the air that is being compressed.
This is accomplished by either a refrigerated air dryer or a desiccant air dryer:
Refrigerated Air Dryer
Refrigerated air dryers cool the air to its Pressure Dew Point or PDP which varies from about 33 degrees Fahrenheit to about 39 degrees Fahrenheit. These types of air dryers are either non-cycling or cycling in which non-cycling units use the refrigerant to cool the air while cycling units only use the refrigerant to cool the heat exchanger within the circuit.
Desiccant Air Dryer
The desiccant air dryer forces the air through a pressurized unit that contains a desiccant material (silica, alumina, etc…) in the form of absorbent beads which capture the atmospheric moisture while during regeneration the moisture is heated to evaporation out of the desiccant material.
It is apparent that air dryers are critical for commercial and industrial air compressor applications. They ensure that the moisture that would otherwise damage sensitive equipment is removed and that the air compressors themselves last longer.
Maintenance and Care
Air compressors and air dryers are a substantial investment for any company. Proper maintenance and care of your air compressor equipment can ensure years of use combined with minimal expenses in costly repairs. Below you will find 5 of the most important maintenance and care steps to ensure long-life and long-use of your air compressor equipment:
- Periodically go through the unit and tighten all of the nuts, bolts, fasteners and screws that are on the unit
- Regularly clean out the unit’s air intake vents and related hoses and filters
- Check, change and service any oil that is used in the system for whatever type of compressor being used and this should be every 500 to about 1000 hours of use
- Depending on the moisture removal system used, check the refrigerant levels, change the desiccant material or drain the air tanks of moisture on a regular basis regularly
- Last but not least, READ the owner’s manual that is provided with the unit for required service guidance
