3D Printing or Additive manufacturing is now the eminent player in the 4.0 Industrial Revolution phase. This technology has opened the door to using materials to make almost anything we can think of and creating a technology that has opened the door for the development of new materials that are developed specifically use in 3D Printing.

Many of these materials are produced by either heating up printing nozzles to temperatures reaching 300 degrees C and above, or by using laser systems to melt metal in the new metal printers or jetting systems that use a wide variety of compounds for creating objects.

All of these systems produce either very fine particulate or significant odors or both. Since 3D Printing or Additive manufacturing is still relatively new, there have not been a lot of studies to determine the levels and size ranges of the particulates that are generated by these machines.

Pure Air Systems has been making HEPA and Carbon based fan powered, air filtration systems since 1985. These systems, ranging is air volume from 50 CFM to 2,000 CFM, are made from all metal housings, using commercial grade HEPA filters and variable speed drive ECM motors. The units come in a number of configurations and control options so they can be attached to any HVAC system , used as stand-alone units and the fans can be controlled to run at any speed.

These systems come with a ring panel prefilter, scanned HEPA certified to 99.99% at 0.3 microns and a large Carbon filter for odors and gases.

In a 3D Printing/Additive manufacturing environment the PAS systems could be used as stand-alone units pulling air from one to four machines and removing the fine airborne particulate. Many newer printers are enclosed so it is easy to attach a small duct to the enclosure and pull that air into the PAS HEPA system.

Another option is to attach the PAS system to the main HVAC units in the lab or production area and remove the particulate and odors using the main HVAC ducting system to pull all the contaminated air back to the filtration unit.

The Pure Air Systems HEPA units have been used on almost every application requiring filtration in almost every corner of the world. They have been used in applications where toxic gases and dangerous airborne particulate are present. Their rugged durability and history of high performance over long periods of time are the reason Pure Air Systems has been in business for 33 years.

When we hear the term “fresh air” we often think about being outside next to the ocean feeling the breeze or on top of a mountain breathing the cool, crisp air. Or, when you are stuck indoors in a building or home for long periods of time you might say, “I’m going outside to get some fresh air.” If we really believe the air is better outside, why do we spend so much time indoors? And, more importantly, what is fresh air?

In reality the term “Fresh Air” is really a misnomer. While it is true that air outdoors is not prone to have that “stale air” smell you have indoors due to lack of ventilation, the levels of airborne contaminants and gaseous molecules outdoors is often not any lower. Yes, that is correct. Depending upon where you are outdoors the levels of harmful airborne particulate and gaseous pollutants can be extremely high.

You already know that during the spring and fall of the year various grasses, weeds, trees, etc. produce pollen of all sorts creating significant allergic reactions and health problems. Is this fresh air? You are outside…aren’t you? Or if you are in a downtown area of a large city you can sometimes feel some stinging in you eyes and throat. That’s usually caused by the high levels of gases such as nitrogen oxide, carbon monoxide, sulphur dioxide and hydrocarbons from all the vehicles. Of course you also have all the airborne particulate that is produced by tires grinding dirt into sub-micron particles. So now that we have identified fresh air let’s take a look at the process of using outside air for ventilation and reduction of CO2 in homes and buildings.

Pure Air Systems has been manufacturing HEPA and Carbon based fan powered, commercial grade air filtration systems since 1985. These units were not only designed to filter the air in a room, home or commercial facility but also to concurrently introduce small amounts of outside air and filter that air prior to introducing it to the indoor environment. As we mentioned before, the term fresh air is really a misnomer. Unless the outside air source is filtered prior to mixing with the indoor environment, it is not fresh air.

The PAS product line is capable of introducing high percentages of outside air that is filtered by three different medias. First there is a polyester dual-layer ring panel filter that is designed to take out the larger particles. Second the carbon media removes many of the odors and gases. Third, is the HEPA filter itself which is a certified HEPA rated at 99.99% removal of all particles 0.3 microns and larger. This three stage filtration ensures that any outside air will be in actuality, “Fresh Filtered Air.”

So the next time you hear the term fresh air remember there are levels of fresh air and you need to make sure that you use the right filtration process to ensure you and your family are breathing fresh air.
