Video Blog: Eliminating Static in the Printing Industry

While we’re still dealing with the high humidity and heat of summer in much of the US, cooler temperatures and lower humidity is right around the corner. Your home energy bill will certainly thank you as the less humid conditions allow you to turn off your A/C. While that’s great for lowering your bills, it creates a favorable environment for the generation of static electricity.

When the relative humidity is high, there’s a higher concentration of water molecules present in the air. These water molecules “coat” the surface of the material, allowing electrons to move more freely and form a layer over the material. This layer of water molecules acts like a lubricant, reducing the forces that cause static to generate. There are many applications that static may only pose an issue once the climate changes.

Anyone who works in the printing industry is sure to be aware of the types of problems associated with static electricity. One common application for EXAIR’s Static Eliminators is the neutralization of static in sheet-feeding processes.

Check out this demonstration depicting how the Super Ion Air Knife can be used to “float” a stack of material and saturate it with static eliminating ions. The SIAK can be operated at very low pressures to prevent disturbing the process, while still maintaining the effectiveness required to neutralize any static present on the surface of your parts or material.

As we begin to approach fall and winter, make sure you’re prepared to handle any static by speaking with one of our Application Engineers. With a whole line of products designed for neutralizing static, we have a solution available to ship from stock to ensure you’re prepared this year!

EXAIR’s Heavy Duty Safety Air Guns Provide Powerful Blowing Force

EXAIR’s Heavy Duty Safety Air Gun is designed to provide powerful blasts of compressed air for use in rugged, industrial environments. With a larger 3/8 NPT air inlet compared to our other Safety Air Guns, it allows for higher force and flow values. It comes with a durable cast aluminum body and ergonomic composite rubber grip. The wide curved trigger allows for continuous use for hours without operator’s experiencing fatigue.

All of EXAIR’s Safety Air Guns come with an engineered compressed air nozzle at the tip. This allows you to remain OSHA compliant while still getting the force you need to get the job done. EXAIR’s Super Air Nozzles utilize the coanda effect to entrain large amounts of ambient air from the environment. This ambient air mixes with the primary airstream and is projected towards the target with more force and flow than the supplied compressed air could deliver alone.

Each of the Safety Air Guns is available with extensions fully assembled ranging from 6”-72”. You can simply add a “-“ and the required length, in inches, to the end of any Safety Air Gun Model number.

In addition, they’re also available with a Chip Shield to prevent any chips or debris from coming back into the faces of your operators. Effective chip guarding is another component of OSHA 1910.242(b) in addition to the concerns of dead-end pressure. To add a Chip Shield onto the gun as well, a “-CS” to the standard Model number. For example, a Model 1310-12-CS would be a 1310 gun with 12” extension and a Chip Shield installed. If the application involves blowing off metal chips or shavings, your operators will certainly appreciate this Chip Shield preventing the debris from blowing back all over them.

Top Factors for Air Compressor & System Maintenance

Performing regular maintenance on your compressor system helps to keep everything operating in peak condition and ensures you’re not wasting unnecessary energy. Just as you perform regular routine maintenance on your vehicles, a compressed air system also needs a little TLC to keep things running smoothly. Neglected maintenance items can lead to increased energy costs, high operating temperatures, and coolant carryover. Much of these issues can be eliminated simply by performing routine maintenance on the components of the system.

According to the Best Practices for Compressed Air Systems by the Compressed Air Challenge (1), components within the system that need maintained include: the compressor, heat exchanger surfaces, lubricant, lubricant filter, air inlet filter, motors, belts, and air/oil separators.  

The compressor and all surfaces of the heat exchanger need to be kept clean and free of contaminants. When these components are dirty, compressor efficiency is greatly reduced. Any fans and water pumps should also be regularly inspected to ensure that they’re functioning properly. The air inlet filter and piping should also be cleaned. The quality of the air in the facility will impact the frequency, refer to the manufacturer’s specifications for ideal intervals for performing scheduled maintenance.

The lubricant and lubricant filter must also be changed per manufacturer’s specifications. Old coolant can become corrosive, impacting useful life and damaging other components while reducing efficiency. While synthetic lubricants are available that have an extended life compared to standard coolants, this does not extend the life of the lubricant filter itself.

Belts should be routinely checked for tension (every 400 hours is reasonable) to alleviate bearing wear. Belts will stretch and wear under normal operation and must be adjusted periodically. It’s a good practice to keep some spares on hand in the event of a failure.

End use filters, regulators, and lubricators should also be periodically inspected and filter elements replaced as needed. If left unchecked, a clogged filter will increase pressure drop. This can cause both a reduction of pressure at the point of use or an increase in the pressure supplied by the compressor, leading to increased energy costs.

Another often overlooked maintenance item is leak detection and repair. Leaks contribute to unnecessary air usage, pressure drop, and increased energy costs. EXAIR offers an Ultrasonic Leak Detector that can be used to identify the leaks in your system and allow you to make the necessary repairs.

In order to keep your system running in peak condition, regular maintenance is critical. By paying close attention to the manufacture’s recommendations, and implementing a regular maintenance schedule, you can ensure you’re getting the most out of your system components.

Conveying Coffee Beans With EXAIR’s Line Vacs

We often take for granted the simple process of brewing a fresh pot of hot coffee in the morning. But do you ever consider where this coffee came from and how it made its way into your kitchen? We’ve documented the life of the coffee bean previously here on the EXAIR Blog.

For manufacturers looking for a way to convey bulk coffee beans (both before and after roasting or grinding), EXAIR’s Line Vac is the simple and easy solution. In many cases, this operation is performed manually by an operator. In applications where operators must manually lift loads of bulk material, this opens them up to a variety of potential risks and hazards.

EXAIR's Threaded Line Vac Family

The EXAIR Line Vac allows you to use an ordinary supply of compressed air and standard hose, tube, or pipe to turn that compressed air into a powerful conveying system. Installation is quick and easy. With no moving parts to wear out or replace, the Line Vac is a maintenance-free product that’ll not only keep your operators safe but also dramatically increase productivity.

This was the exact case for a customer of our Colombian Distributor (home of some of the best coffee beans in the world). They were seeking a method of transferring their whole and ground products automatically so as to eliminate any potential safety concerns to their personnel. What turned out as simply a means of increasing safety, also provided them with an ability to transfer the product more quickly.

They were manually moving bulk sacks of coffee at a rate of approximately 80kg/hr. With the Model 141100-316 (1” NPT Threaded 316 SS) Line Vac, they were able to convey 150 kg/hr of ground coffee and 250 kg/hr of coffee beans at a height of over 30’ (10m). So, not only did they eliminate a potentially hazardous process, but they were able to move nearly 2x the volume of coffee in the same time period.

EXAIR’s Line Vacs are available from stock in aluminum, type 303 & 316 stainless steel, and a hardened alloy steel for use in abrasive applications. Each style is offered with either smooth connections for use with smooth-bore hose, or with NPT threads depending on your preferred connection style.

Available to ship same day from stock with orders in by 2:00 ET and backed by our unconditional 30-day guarantee, there’s no excuse not to try one out in your process! If you’d like to discuss a possible application for our Line Vacs, feel free to get in touch with us via phone, chat, or e-mail.
