Maximizing the Energy Efficiency of Your Compressed Air System

Air compressors are some of the most demanding energy users in a plant. In fact, over the life of an average compressor, the energy cost often exceeds the equipment cost several times over. Improving your air compressor’s energy efficiency can make a huge impact on your bottom line. Here are a few ways to reduce the cost of producing compressed air and maximize your energy savings:

Request a Compressed Air Energy Audit

Having a professional perform an air audit to measure your current flow rates, energy consumption and operating pressure can help identify significant cost savings. Often, evaluating things like how your compressors are controlled or whether you need extra storage can improve compressor efficiency. Air audits should be performed on a regular basis and any time changes have been made in your plant that may impact your compressed air system.

Find and Repair Air Leaks

Leaks in your system cause an unnecessary load on compressors, which inevitably requires more energy and maintenance. Without a proper air leak maintenance program in place, leaks in your air compressor could account for 20–30% of your total air demand and cost you thousands of dollars a year in wasted energy. Some leak surveys have actually enabled customers to completely shut down extra compressors.

Reduce Air Pressure

Less pressure = less energy. It’s that simple. According to the Compressed Air & Gas Institute, for every 2 psi reduction, you can save approximately 1% in energy consumption. Make sure your system hasn’t been set at a higher pressure than is necessary or requiring additional pressure as a result of leaks.

Maintain Your Equipment

Compressed air equipment is a big investment. Avoiding regular maintenance can lead to inefficient operation, costly repairs and even equipment failure. Following a consistent preventive maintenance schedule is a smart way to protect your investment and maximize savings. Changing filters and lubricants and having your equipment inspected regularly will keep it running efficiently and reduce your total cost of ownership.

Put Wasted Heat to Work

Compressing air naturally generates heat. Generally, this heat is wasted, but the majority of it can actually be recovered and used for operations like heating a warehouse or providing hot water for cleaning.

Use Your Energy Wisely

Too often, compressed air is used for tasks that could be completed more economically, such as using it as a blower to clean up or as a fan for cooling. Make sure your staff is educated on proper and improper uses of compressed air.

At Lewis Systems, we want to make sure you’re getting the most efficient performance from your system. Our factory trained service team can perform everything from ultrasonic leak detection to an in-depth Energy Audit and Air Study. We also offer maintenance, service plans and compressor repair services to ensure your equipment is operating at peak efficiency. To discuss your energy needs, contact us at 800.222.4553.

PD Blowers and Vacuum Pumps: Why Replace the Whole Package?

Keeping positive displacement blowers and vacuum pumps well maintained by performing small repairs can extend the life of both pieces of equipment. But as they age and corrosion occurs from moisture inside the inlet and discharge silencers, both will eventually need to be replaced. When the time comes to replace a bare blower or vacuum pump, it’s smart to consider replacing the whole package.

Advantages to Replacing the Whole Package:

  • Energy efficiency: New packages are considerably more energy efficient and could help provide long-term cost savings for your operation.
  • Reduced noise: New packages are often quieter and can reduce pulsation issues.
  • Space savings: New smaller packages can accommodate sizing requirements that have changed since the original package was installed. They’re also easier to access for repairs.

As you evaluate your positive displacement blower and vacuum pump package needs, there are a few questions you should consider to make sure the replacement process goes smoothly.

Does the blower motor need to be replaced?

If your PD blower is showing signs of wear, how much longer do you really expect the drive motor to last? Replacing the motor before there is a serious issue can help avoid a costly breakdown.

What type of blower do you need?

New tri-lobe or helical screw blowers are more efficient than a bi-lobe blower. Upgrading your blower style can also reduce pulsation and noise.

Would you like new controllers or VFDs?

New packages can be fitted with all sorts of controllers, monitors and variable frequency drives.

Could you benefit from a new cabinet enclosure?

Upgrading or adding a cabinet enclosure could help reduce noise.

Is it time for new gauges and/or monitoring?

New packages offer intelligent monitoring solutions that can help you keep track of how your equipment is performing at all times.

Lewis Systems sells and services major PD blower and vacuum pump brands such as Gardner Denver, Powerex and Travaini. Our factory trained and certified technicians can work with you to determine the extent of your repair or replacement needs.

Air Compressor Troubleshooting Guide

air compressor troubleshooting guide to help with compressor repairs

When an air compressor goes down, productivity can immediately slow or stop. Fortunately, there are some things you can check yourself to see if you’re facing a major compressor issue or something that can quickly be resolved. 

My compressor won’t start.

You’re pressing the button but nothing’s happening. You may be experiencing an electrical issue or your compressor’s safety device may have been tripped. Check the:

  • System display for errors
  • Power supply and fuses
  • Wiring system for wrong lead connections
  • Temperature shutdown switch
  • Motor starter overload heaters
  • Oil level

My compressor starts, but it won’t stay on.

If your compressor will only run for a short time, it’s possible that the unit is overheating. Check the:

  • Discharge temperature switch setting
  • Oil level, oil cooler and oil filter
  • Thermostatic mixing valve (rotary screw compressors)
  • Temperature shutdown switch
  • Motor starter overload heaters
  • Room ventilation and ambient air temperatures

My compressor is very noisy.

A compressor that is making loud noises likely has a part that is loose, damaged or worn out. Check for:

My compressor is using too much oil. 

If your compressor is using an excessive amount of oil, you probably have a leak. Check for:

My compressor isn’t delivering enough pressure.

You need a certain amount of pressure to run a tool or complete a task and the compressor can’t seem to keep up. First look to see if there’s an air leak in the hose or piping, then: 

  • Make sure the inlet valve is not restricted or broken
  • Check for air leaks downstream
  • Check for improperly adjusted controls
  • Clean or replace the air filter
  • Tighten belts if applicable

It’s important to follow basic safety procedures when troubleshooting. Always open the main disconnect switch and remove all power from the unit before trying to determine the issue. Follow “Lock Out” or “Tag Out” procedures. Also, remember to relieve the system pressure before removing parts or breaking any lines. If you are experiencing a serious compressor issue or can’t determine why your compressor isn’t working, contact Lewis Systems at 800.222.4553. Our dedicated service team can troubleshoot your air compressor and help you determine next steps.
