Introductory Terms & Concepts


Does your company have a new crew of salespeople? This post is packed with introductory terms and concepts, and will help your rookies sound like pros when educating end users. 

According to Merriam-Webster’s Dictionary, compressed air is defined as air under pressure greater than that of the atmosphere. Compressed air can also be described as being free air that has been pressed into a volume smaller than it normally occupies. As it exerts pressure it performs work when released and allowed to expand to its normal free state. In today’s blog post, you will learn the basics of compressed air which will increase your credibility when speaking to clients about Quincy compressors. 

Why is compressed air used and who uses it? Since compressed air is essentially stored energy, there are numerous industries that use compressed air for various applications. It supplies motive force, and is preferred to electricity because it is safer and more convenient. Compressed air is the 4th utility to industry and is as important as water, electricity and fuel (gas, oil, etc.)

The great advantage of compressed air is the high ratio of power to weight or power to volume. In comparing electric motors, compressed air produces smooth translation with much more uniform force. Compressed air equipment can be more economical, and more durable without the shock hazard of electricity or the explosion hazard of oil. From a production assembly line to laboratories to heavy construction, compressed air can be used in endless industries. Below are a list of examples in which compressed air can be used: 

Production Line Tools – Automation & Assembly Stations – Plant Maintenance – Chemical Manufacturing – Aircraft Mfg. – Automobiles – Beverages – Agriculture – Cement – Foundries – Plastics – Construction – Hospitals – Monuments – Power Plants – Sewage Plants

The ability of a compressor to supply energy is expressed in both cfm and psig. CFM or Cubic Feet Per Minute is the volume of air measuring the compressors capabilities. The amount of stored energy, or the ability of the compressor to supply this energy is expressed in both cfm and psig. CFM, or Cubic Feet Per Minute is the volume of air measuring the compressors capabilities, and PSIG means pounds per square inch gauge. Compressed air is usually 100 pounds over atmospheric pressure, or PSIG. Atmospheric air can be compressed in several ways: Positive Displacement Compressors, machines in which successive volumes of air are confined within a closed space and elevated to a higher pressure; Dynamic Compressors, machines in which air is compressed by the mechanical action of rotating impellers imparting velocity and pressure into the air; Centrifugal Compressor, which operates like a fan where the flow through the compressor is turned perpendicular to the axis of rotation. The volume (measured in CFM) required determines the size of the compressor needed to do the job. 

For example, a five horsepower compressor will supply 20 CFM at 100 PSIG. A 200 HP compressor will supply 1,000 CFM at 100 PSIG. So, the more volume, the faster the job gets done. In addition, greater pressure increases the force or torque. Some tools, motors, or hammers will not operate without sufficient volume, so it is very important to know what type of compressor to recommend for a specific application. 

Moisture in compressed air can cause big problems Hot air holds more water vapor, so it is vital to performance to make sure the air is cooled and the moisture is removed. To do this, an air cooler aftercooler, moisture separator and refrigerated air dryer are used. Some problems caused by water in compressed air include: maintenance and war increases; air equipment becomes sluggish; rust; air line freeze; shorter air tool life. 

Don’t forget that supplying compressed air is not free. The cost of compressed air can be one of the most expensive sources of energy in a plant. To calculate the cost of compressed air in a facility, use the formula shown below:

Cost ($) =

(bhp) x (0.746) x (# of operating hours) x ($/kWh) x (% time) x (% full load bhp)

Motor Efficiency

Where bhp = Compressor shaft horsepower (frequently higher than the motor nameplate horsepower = check equipment specification) Percent time = percentage of time running at this operating level Percent full-load bhp = bhp as percentage of full-load bhp at this operating level Motor efficiency = motor efficiency at this operating level. 

Case Studies

In today’s competitive sales world, finding ways to establish rapport and credibility can sometimes be tough to find. One tool often overlooked is a “referral” from current customers. Testimonial-type endorsements give potential customers more reasons to purchase from you. Research shows that testimonials can increase sales in consumer businesses by 30 percent and double or triple results in B2B sales.

Quincy Compressor believes these statistics to be true and has published more than half a dozen case studies to assist in spreading the word. A case study is a great way to not only put the spot light on the customer’s success story, but to also shed some light on the company who serves as the compressed air specialist. Although case studies are like endorsements, they are better because each one focuses on a specific industry issue and how a Quincy distributor and product provided the solution.

Now it’s your turn to submit a case study. Why not put your story out there for everyone to see? You’ve been working hard, not it’s time for you to shine! We’re looking for case studies of those who have purchased Quincy Compressor products. Step into the spotlight when your case study turns into an actual published piece for others to read and admire!

Business Resolutions

business planResolutions don’t have to be made solely on New Year’s Eve. In addition, to your personal resolutions, why not make resolutions to help your business grow? One way you can do this is by creating a business plan for your company. A business plan will help you set goals and provide a road map for you to follow, ensuring those goals are met. Careful planning is fundamental to success. Each year, business goals and focuses change based on changes in the economy and other outside elements beyond our control. Far too often, people think they can achieve their goals but fail to outline the steps to help them along the way. That is where this plan will serve as a compass when the winds change.

So where do you start? Since each business is unique, you will need to create a plan that is specific to your needs. The first step is to identify what goals you would like to achieve this year and what goals will lead to growth. For example, let’s say one of your objectives for 2015 is to build a company website (or update an existing one) that will help customers identify your company’s products and services. You will need to identify this as a goal in your business plan, and then outline the steps you will take to achieve it. Also include your financial needs to get the website updated or started. This will help you set a budget and stick to it. Next, consider any low-hanging fruit. Have you included all of the areas that will build your customer relationships?

Along the way, evaluate your progress towards the goal. Schedule weekly or bi-weekly update meetings with everyone involved to find out if you are on track, see if any changes need to be made to strategy, etc. You should also do an evaluation upon completion. The knowledge you take away from this project will help you in setting goals and creating more accurate business plans in the future.

All of this may seem intimidating if you are not used to practicing it annually, but rest assured, there are plenty of resources available. You can find books, online publications and articles that will get you started and help you along the way.

Compressed Air Systems: An Introduction

SystemDid you know that compressed air is so widely used that it is often regarded as the fourth utility, after electricity, natural gas and water?

Compressed Air System Components

A compressed air system is much more than just an air compressor. A basic compressed air system is made up of the following components:

  • The Air Intake Filter is a device composed of fibrous materials designed to trap atmospheric airborne particles such as dust, pollen, mold, etc. before they can reach the compressor.
  • The Air Compressor is a machine used to convert power (usually from an electric motor, a diesel engine or a gasoline engine) into kinetic energy by compressing and pressurizing air, which, on command, can be released in quick bursts. There are several different types of air compressors, including reciprocating, rotary screw, and rotary centrifugal.
  • The Aftercooler cools the system lubricant and discharged air.
  • The Air Receivers provide compressed air storage capacity to meet peak demand events and help control system pressure by controlling the rate of pressure change in the system.
  • The Air Dryer removes condensation from compressed air in order to prevent damage to the system.

Compressed air systems last 10 to 15 years on average. The top two causes of premature system failure are improper installation and improper maintenance.

Simple Tips for Maintaining Your Compressed Air System

It is recommended that your compressed air system be professionally serviced at least annually.

Keeping air filters clean can lower your compressed air system’s electricity use by 5 – 15%. Change your filter every three to six months.

Check your drain traps to make sure these contaminant removal devices have properly functioning drains and no blocked lines.

Check your oil. Just like a car, your air compressor needs regular oil changes or you risk destroying the engine.

Stay Alert for Warning Signs such as unusual noises, overheating, excessive vibrations or belt slippage. 

Choosing the Right Filter for Your Compressed Air System

The proper filters play an important role in your industrial air compressor system. Choosing the right filter not only increases the efficiency of your unit, it can also lower energy costs and protect your employees from harmful chemicals and particulates. Listed below, are the different types of filters commonly used in industrial compressed air systems: 

  • Coalescing Filters – removes dust, oil, mist and liquid condensates
  • Particulate Filters – designed to remove high concentrations of solids, burnt oil and bulk liquids
  • Activated Carbon Absorbers – removes vapors and odors.

What is Compressed Air?

Air at greater than atmospheric pressure- usually 100 pounds over atmospheric pressure- or 100 PSIG. P.S.I.G means pounds per square inch gauge. Air which has been compressed above atmospheric pressure will return to atmospheric pressure when released. Therefore; compressed air is STORED ENERGY! The amount of this stored energy, or the ability of the compressor to supply this energy is expressed in both CFM and PSIG.

CFM or Cubic Feet Per Minute is the volume of air measuring the compressors capabilities. A good rule of thumb is one HP will provide about 4 cubic feet of compressed air at 100 PSIG.

Example: 5 HP Compressor will supply 20 CFM at 100 PSIG
              100 HP Compressor will supply 1,000 CFM at 100 PSIG
