Ever wonder how much motor grease is enough when pumping it into a motor? Or what type of grease is the best? We wondered the same so we invited in John Wojdyla from Timken, to educate us on bearing greasing. We took our previous knowledge and combined it with what he taught us to produce the below information. The challenge we face as an air compressor service company, is that we maintain many different brands of compressors that use different brands of motors, some of which are domestic and many that are European and Asian. To add to the confusion,... Read more »

Winter is upon us again. We all know the summer went too fast, but hey – how can you be better prepared for the cold weather? By learning how cold ambient temperatures affect your compressed air system! Temperatures below freezing can have many adverse effects on compressed air equipment. The one that is most obvious is that compressed air generates condensate. Condensate will freeze when temperatures drop below freezing. This can cause short-term and long-lasting damage to your equipment such as freezing control lines, freezing and cracking of heat exchangers, frozen drain valves, and much more. Ideally, your air compressor... Read more »

There is really only one key difference between fixed speed and variable speed drive rotary screw air compressors; the way the motor is controlled. There is very little variation in the way the machine compresses air. Basically, a VSD machine varies the frequency and voltage supplied to the electric motor, thus allowing the speed of the motor to be efficiently controlled with the demand for air at any given point in time. On the other hand, a fixed speed compressor gives consistent frequency and voltage to the motor, meaning that when the demand for air is lower, the efficiency is... Read more »

How does pressure drop cost me money? Every compressed air user needs to understand the importance of minimizing pressure drop. Pressure drop is costing you money if, in order to maintain the desired pressure at your point-of-use, you have to run your air compressor at a higher pressure than the minimum pressure needed to keep your factory operating. It takes more energy to produce air at a higher pressure, and energy costs money. To put it in context: If a machine only needs 90 PSI to function properly, but you have to operate your air compressor at 120 PSI in... Read more »

1. How large is your demand? Rotary screw air compressors are especially durable and are able to handle large amounts of demand for extended periods of time. They are still more efficient and durable in smaller horse powers than piston compressors, but this is noticeable when getting into larger demands (i.e. 15 horsepower and more). Rotary screw air compressors are designed to run at 100% duty cycle, day in and day out. 2. Is lifetime cost important to you? While yes, a rotary screw compressor may have higher air compressor maintenance cost and/or initial capital cost, the lifetime expectancy is... Read more »

Inline filters are used to keep your compressed air clean and free of particulates and oils that are passed from your compressed air equipment into your system. These filters can technically be placed anywhere in the compressed air piping systems. Some of the most common placements are the following: Directly after the commercial air compressor Before and after the air dryer (refrigerated air dryers, desiccant air dryers) Just prior to point of use (i.e. on each compressed air drop) All of the above Or any other way that is specific to your system’s needs Keep in mind, the better the compressed...

What are the main differences between refrigerated and desiccant air dryers? Refrigerated Air Dryers A refrigerated air dryer chills the compressed air to 33 – 40 degrees Fahrenheit at which water vapor is condensed into a liquid and is then expelled from the system via a water-trap and automatic drain. The cool dry air then is typically re-heated to around room temperature before exiting the dryer and going to your production lines. This helps reduce condensation on the compressed air piping. There are two types of refrigerated dryers; cycling and non-cycling. Non-Cycling Air Dryers: Non-Cycling air dryers allow the refrigeration circuit... Read more »

Changing the oil on your rotary screw air compressor is important for the life of the machine and can avoid large repair costs. On top of checking it regularly to ensure it’s topped off, you should change it at regular intervals. The length of this interval depends on the type of oil being used in your machine. Rotary Screw Air Compressor or Rotary Vane Air Compressor** Standard Oil every 8000 hrs or 12 months Food Grade Oil every 2000 hrs or 3 months If you don’t change your oil as above a few things can happen to your compressor: Buildup...

1. Loop type distribution system – In most cases a loop type distribution system is beneficial. Loop type compressed air systems allow the air to flow in any direction to get to the demand in the path of least resistance. Typically you can multiply the capacity of straight line piping by 1.5 for loop type compressed air distribution systems. For example: If a 2” pipe is rated for 500 CFM at 125 PSI that same length of pipe in a loop system would be rated for 750 CFM at 125 PSI. 2. Feed the loop type piping from a dry... Read more »

There are 2 key aspects to sizing your piping correctly: max system CFM requirements and minimum required operating pressure.   Max CFM A study needs to be completed to determine what the max demand in the system (in CFM) is going to be. This needs to be a worst case scenario, with even momentary uses being considered Momentary uses of compressed air are considered any usage of your air for a period of time that is less than a minute. Examples of these momentary uses are; dust collector blow down valves, large air cylinder/ ram actuation, sometimes diaphragm pumps, and... Read more »

Have you ever dusted yourself off with compressed air and ended up getting power washed with water instead?! Where did that water come from and does it belong there? As we learned in science class, the air we breathe contains water in a gaseous state. The compressed air industry expresses the amount of water in a system by dewpoint and relative humidity. The warmer the air, the more water the compressed air can hold. This is why we see so much more water in our compressed air on a hot summer day after it has rained. When we compress the...
