1. Keep a close eye on your filters

In our current times, think of your compressor filters like a person wearing a face mask. Wearing a mask restricts your air flow when breathing. That’s exactly what a dirty filter is like. It requires a person to use extra energy to inhale, just as it requires a compressor to expend extra energy to operate. Air, oil and sump filters are all important to keep a close eye on.

Air filters are vital components in a compressed air system. Not only do air filters help remove contaminants and debris, but they also help the compressor operate more efficiently and minimize the impact of wear and tear. Therefore, you need to routinely inspect and replace filters.

Air filters create pressure drops which is monitored by the engineering unit of inches of water column. A new filter might be 5-8 inches of water column, while a dirty filter could be 20 inches of water column. The higher the water column, the more it will block the inlet air, so you can’t load. Ultimately, this means your machine is working harder and consuming more energy than is needed.

Oil filters are similar. When dirty, it will cause the oil system to require more power to filter through a higher psi drop across the dirty filter. Make sure you are maintaining both the oil filter and the separator element, which is sometimes referred to as the sump filter.

2. Get an oil sample on your compressor

This is a commonly overlooked component of good air compressor maintenance. Oil sampling and analysis helps identify problems in the early stages, which helps minimize downtime, reduce repair costs and ensure energy efficiency.

Not only do oil samples help ensure your oil quality is good but it also checks for metal particulates, which indicates there may be larger issues at hand, such as a failing air end. The dirtiness of the oil is also an indicator that other consumables need to be changed – things like the sump filter or oil filter.

Depending on your environment, you may need to change your oil more frequently than is designated by the OEM. For instance, in dirty environments, you may need to change the oil every 6,000 hours versus every 8,000 hours.
 

3. Keep your OEM maintenance on schedule

OEM maintenance should not be viewed as a burden or excessive maintenance, but parts simply wear down, where they degrade over time or from usage. Sullair strives to stand behind its promise of durability and reliability by replacing the key components in the compressor to allow for longevity and optimal performance of the compressor. We take pride in our compressors lasting 10, 20 or even 40+ years. We hope your compressor lasts that long, too, but it means you need to keep up with OEM maintenance to allow proper cooling, filtering, and health of the machine. This is the simplest way a customer can protect their investment in their compressed air system. You should also be careful to never use non-OEM, “will fit” parts. You may think the upfront cost savings is worth it. In reality, saving a few dollars on "will fit" parts hurts the large investment of the compressor in the long run. For example, even though a cheaper filter may fit, the media in the filter is never the same as the OEM filter, which can cause more expensive components like the air end to fail. Saving a few dollars now could cost you thousands in the future!

4. Assess your compressor room and system as a whole

A compressor room is more than just a compressor, so look at all the other components. For instance, you should always have a tank. A properly sized tank can optimize the energy consumption from the compressor. Regarding maintenance on a tank, make sure moisture is not being collected in the tank and that there is no water in the tank. If there is water in the tank, you need to either remove the moisture or invest in a higher quality drain.

There are multiple types of drains on the market, but not all are created equal. Some drains that let out moisture also end up letting out compressed air, and compressed air is your money! This is compared to Zero Loss Drains, which only let out moisture and not compressed air. Stay tuned for an upcoming blog on the types of drains and to understand the benefits of Zero Loss Drains over automatic or manual ball drains.

If you have inline filters, make sure they are being properly changed per the time intervals required. Many in line filters have a gauge to show if they are green (good) or red (needs replacement). Take some time to inspect the filter element, not just the gauge.

Also look at your dryer. Is it properly drying the compressed air? Is the OEM's dryer maintenance plan being followed? Inspect the drains on the dryer.

Leaks are a big concern of any compressed air system. Make sure you are using quality pipe that does not corrode if you have the luxury of replacing or selecting pipe for the compressed air system. Make sure red rubber hoses, which are prone to leaking, are not used and replace and inspect properly.

5. Monitor load cycles

Assess your compressor to determine if it has a lot of load cycles or not, as you do not want it to continuously turn on and off. Make sure there is proper time between each cycle.

If you determine there are a lot of load cycles, try adjusting your pressure set points. Even reducing your compressor by 2 psi cuts energy consumption by 1 percent*! Changing the pressure does not increase or decrease the air flow (cfm), which is a common misconception.

By understanding what psi your downstream equipment truly requires, you can better align the output of your air compressor. Often end customers test the waters by turning down their compressor 1 psi each week and assessing how their downstream equipment reacts. Going into this, do understand if it begins impacting your equipment downstream, you will need to readjust accordingly (by increasing psi).

6. Assess energy savings

Once you adjust your psi to the optimal pressure for your processes, you can then use a tool such as Sullair AirSuite to determine how much you’re saving in energy costs. AirSuite provides an analysis of your entire compressed air system via easy-to-read reports, helping you make the right decisions for your operations.

If you are looking for new equipment in next year’s budget, now is the time to do your homework. A proper air audit and simulation with AirSuite can provide you with ROIs when you replace your equipment with new, efficient equipment.

Everyone would love the efficiency of a brand-new air compressor, but we know the reality of challenging economic times. Fortunately, there are many simple and low-cost measures you can take today to ensure your current air compressor system is as optimized as possible to get you through to more promising economic times.

In the world of compressed air systems, the air compressor filter is an unsung hero. It plays a crucial role in ensuring the efficiency, longevity, and safety of your equipment. 

Whether you're a seasoned professional or a newcomer to the field, understanding the importance of air compressor filters and how to maintain them can save you time, money, and headaches. This comprehensive guide will delve into the various aspects of air compressor filters, from their types and functions to the benefits of regular maintenance.

Imagine if you wake up one day, looking forward to drinking your amazing coffee, and you run out of filters. This means your morning coffee is full of grounds and clumps of thick, muddy gunk. That’s a bad new, especially when you remember how wonderful coffee is when it’s properly filtered. 

As for the coffee, also your compressed air risks to be contaminated. An air compressor filter is essential for any compressor installation as it protects the system from harmful particles like dirt, dust, and oil. A high-quality air compressor filter not only prevents damage to equipment and downstream machinery but also safeguards the manufactured product, avoiding loss of production and minimizing the risk of heavy costs. 

When you install an air compressor filter, you:

• Protect Your Equipment: Filters prevent damage to compressors and downstream machinery.  
• Ensure Product Quality: Filters safeguard the manufactured product from contamination.
• Reduce Operational Costs: Proper  filters minimize the risk of breakdowns and costly repairs.
• Enhance Efficiency: Air compressor filters reduce pressure drops, leading to lower energy bills.

Particulate air filters are designed to remove dust, pollen, dirt and other impurities. The better the quality of the filter, the smaller the particulates it blocks. And the quality of the air you need will define the quality of filter you need. All the nasties are trapped on the outer side of the filter, with only air of an acceptable quality passing through into your compressed-air network. 

Particulate air filters are most frequently used after an adsorption dryer. If you find there’s still too much moisture in your air after it’s passed through the particulate filter, you may want to look at a coalescing filter. And if you want a finer filter to remove fumes and vapours, an activated carbon filter should do the trick.

Also known as vapour removal filters, activated carbon filters remove vapours. In fact, the activated carbon in the filter attracts and draws vapours to the filter. This means any kind of gaseous contaminants like chemical fumes and chemical vapours—even odours and smells—are filtered out. 

The filter has a large surface area, giving the activated carbon a much larger opportunity to work its magic. Of course, as the filter becomes more saturated or clogged with the vapours it has filtered out of the air, it will need to be replaced. Otherwise, the pressure will drop. And, of course, you don’t want that.

Activated carbon filters are mostly used in the food-processing industry and other places that require the production of pure, clean, breathable air.

The filters are very easy to maintain. For this reason, they’re often combined with one of the particulate filters you’ve just read about. This offers extra protection in case any of the carbon particles break off the filter and escape into the air.

Of course, there are times when there are better options than activated carbon filters. If you need to remove moisture from your air, you’re best using a coalescing air filter.

Coalescing air filters are designed to remove liquids and moisture. This makes them sound like air dryers. They’re different, and, they work best when operating in conjunction with an air dryer. Install your coalescing air filter a little further down the line from your air dryer so that the majority of the moisture has been removed. Otherwise, your coalescing air filter will become saturated very quickly.

A coalescing filter is best dealing with water, lubricants and other oils when they’re travelling as tiny little particles in an aerosol form. The coalescing air filter basically opens up pathways that force the tiny particles to collide with each other and form larger particles that are more easily caught and filtered out. 

It's worth noting that coalescing air filters will catch other particulates, like dust, pollen and dirt, that a particulate filter would also catch. This means that coalescing air filters score big points for versatility. However, this compressed air filter types are not as efficient as the particulate or the activated carbon ones. They need to be replaced fairly regularly to avoid pressure drop.

The first step to identifying what compressed air filter type you need is to find out the quality of compressed air you need. If you’re inflating the tyres of trucks in a quarry, you won’t need the same air quality as a dentist or a company manufacturing medicines. The quality of air you need will define the type of compressed air filters you need in your compressed air network. Of course, it is possible to filter the air to an incredibly fine degree in any situation. However this is a very costly solution.

You’ll also want to factor in the long-term costs. There are compressed air systems with a relatively small price tag when they’re sitting on the shelf. However, the cost of operations, repairs and new materials will add up over time. If you’re just looking at an air compressor for occasional use, this won’t be a problem. If you’re going to be using it continuously, you’ll want to do a bit of extra homework.
