Air Filtration For Your 3D Printer

For five years I have been working with 3D Printers of all types and have printed with over 20 different filaments from PLA to PETG and even Bronze. Some of these filaments when heated to over 205 degrees C to melt them for extrusion give off no noticeable odor Some, like ABS, Polycarbonate and Nylon do emit an odor. Often  a very strong odor.

It is also known that some measure of small sub-micron sized particles are released during the printing process as the extruder moves the heated filament from the nozzle to the build platform. Gases and particulate that are, perhaps,  benign in small quantities but potentially harmful in large quantities or over long terms of exposure.

Pure Air Systems along with its partner, LiteWorld LLC , have developed a plexiglas enclosure with two large access doors that will fit over most large bed 3D printers allowing for two benefits. First, the enclosure has a fan and carbon media filter to capture any odors that might be produced by the materials during the printing process. Second, the unit will significantly minimize the amount of fine airborne particles that are emitted during the printing process.

Air filtration for your 3D printer is perhaps something you don’t think about but it should be on your radar at this point in the evolution of 3D printers. Especially the FDM or FFF printers that use filament in the 1.75 mm or 2.85 mm size range.

The other reason for the use of the enclosure is the safety it provides in keeping little hands out of the moving mechanisms and from the very hot nozzle and build platform. Many schools are now requiring the use of an enclosure to fit over the printer to keep them free from any liability when used in the classroom.

Isolation Room

Isolation is a word that means to separate from or detach from another area in all aspects. Isolation rooms are used often in the medical market to maintain a safe environment from the general public by isolating a dangerous or highly communicable diseased patient from the the general population.

Isolation is more than just separation by walls and doors. In the realm of airborne viruses you require a special filtration method to ensure that any air that is passed between the isolation room and the outside world is properly filtered. This is always done using HEPA based air filtration systems to remove even the smallest airborne particles to eliminate the possible transmission of deadly diseases.

Pure Air Systems has been providing commercial grade, certified HEPA and ULPA filters for a wide range of applications and markets since 1985. HEPA filters have been the only true mechanical filter type that has the ability to absolutely trap the airborne allergens and pathogens that are associated with creating serious illnesses and health issues since the early 1980’s.

Pure Air Systems also makes HEPA systems that can be used in the residential, institutional, commercial, industrial and military markets. After 32 years of being in business Pure Air Systems has well over 10,000 units in the field in both the US and overseas.

Seven different models are available from fan powered air volumes starting at 50 CFM to 2,000 CFM. All the systems use the new variable speed drive motors and they are all rated at, 120/240 volt, 50/60 Hz so they can be used anywhere in the world.

The all metal housings and commercial grade components ensure that these systems will provide high performance service over very long periods of time.  For more information on the complete line of HEPA and Carbon based systems, please go to our website at: https://www.pureairsystems.com  or call us on our toll-free number at: 800-869-8025.

HEPA For Terrorism

We are constantly reminded that we live in a era where anyone at anytime can create mayhem with simple, exotic or well crafted killing tools. There are no limits as to what device a motivated anarchist can do with any of these style devices. Yet, for all the external damage that can be done with hard technology, the invisible, airborne pathogen still creates the greatest threat.

Tiny viruses and bacteria are invisible to the naked eye but can be a major threat to our bodies if these pathogens are inhaled, absorbed or injected into our systems. The only true method of totally removing these objects is to use a mechanical filter such as HEPA. High Efficiency Particulate Air filters have been around since 1940 but their real push into the market came in the late 70’s and early 80’s with the development of the micro-chip.

As HEPA technology improved the types of HEPA paper and testing methods became more effective especially as organizations like the CDC began to work with some really horrible contagions and had to isolate them in special rooms with multiple levels of HEPA filters including the newer ULPA (Ultra Low Particulate Air ) and the new SULPA (Super Ultra Low Particulate Air) filters.

In 1985, Pure Air Systems came onto the market offering true, commercial grade, fan-powered HEPA air filtration systems. This was the first true entry of commercial grade HEPA units into the residential market place. Over the years a total of 7 HEPA systems were produced by PAS and the incorporation of the new ECM motors allowed them to create models that had variable speed motors and that could be sold anywhere in the world.

These systems are considered some of the best HEPA filtration systems in the world and have been used in applications where the facility is being prepared to protect against biological attacks. There is no better filter for removal of harmful airborne pathogens than HEPA.

Stand-Alone Air Filtration Systems

Air filtration systems for both residential and commercial applications come in a variety of types and performance packages. Depending upon the type of particulate or gaseous pollutant that needs to be removed, the filter media used in the air filtration systems can be general duty filters or high efficiency filters such as HEPA media.

Stand-Alone units mean just that. They are units that incorporate a blower/motor system that is capable of pulling air from an area and pushing air out to the environment or other area. These systems can range in volumes of air moved ( as measured in CFM, or cubic feet per minute ) from a low of 50 CFM to 2,000 CFM and higher.

Pure Air Systems has been making HEPA based, fan powered, commercial grade, stand-alone units since 1985. These systems use the newer ECM Variable Speed motors that can be automatically or manually adjusted to produce various ranges of air movement (CFM). This feature makes the units more viable for a multitude of applications using one system.

Pure Air Systems offers 7 different variations of their Hepa Shield Plus units including a small, powerful portable unit for laboratory type applications. Each unit has a dual-layer prefilter, carbon media and true HEPA filter. These are all commercial grade filters and are designed for even the most difficult of pollution control applications.

PAS stand-alone systems can be mounted on a wheeled cart or platform and moved from location to location. The S versions have threaded nuts in the top section so they can be mounted from a ceiling using threaded rod. The units come in 1/3, 3/4 and 1 HP versions and all the motors are rated, 120/240 volt , 50/60 Hz so they can be used anywhere in the world.

Allergies Are Airborne

Most people who suffer from allergies caused by grass, ragweed, tree pollen or animal dander connect with this allergen through ingestion through their nose or mouth. All of these allergens are airborne and whether you are inside a home, building, school or other indoor environment avoiding the outdoors will not protect you from breathing in these tiny, airborne particles.

Often you will see pollen residue on a table outside or even on windows in your car. However, much of the airborne particulate are smaller than 20 microns which makes them invisible to see with the naked eye. These  tiny particles are carried into the home or building on your clothes as you transport them from one location to another. Then when you walk or move you shake off the allergen particles and they become airborne again which brings them into the air for you to inhale…..again.

Home air filters or furnace filters are not capable of removing these small, sub-micron sized particles. Only HEPA filters will actually remove these tiny airborne particles and the best solution for your home is to install a whole-house HEPA system from Pure Air Systems.

PAS has been making whole-house HEPA filtration systems since 1985 and is the leader in producing a wide range of fan powered, commercial grade, HEPA air filtration systems that use variable speed drive blower/motor units which allow for use as part of your HVAC system or as stand-alone units where you can control the fan speed in 1% increments up to  100% of fan speed.

These systems come with a scanned 99.99% commercial grade HEPA systems, a ring panel prefilter and a true Carbon filter. The PAS housings are all metal as is the blower. Typical life span of these systems is 15 to 20 years.

HEPA Filter Systems With Variable Speed Fan Drives

True, commercial grade HEPA filtration systems use a very dense HEPA paper media that requires a fair amount of energy to pull air through it using a radial blade fan. This is one reason that you have very small portable style units for the residential market as they use much smaller HEPA filters and fractional horsepower motors to keep the costs down.

These home HEPA units can usually provide up to 150 CFM of HEPA filtered air as a maximum rate and as the HEPA filter loads up it will slowly back down to the increase in static pressure.

Pure Air Systems offers a line of commercial grade HEPA filtration systems that use the variable speed ECM style motors that us magnets to turn the motor rather than copper windings. This allows for incremental speed adjustments to the motor so that the appropriate amount of horsepower is used to meet the preset CFM volume.

These motors can be programmed to speed up as the resistance across the HEPA filter increase due to dust loading thus providing a constant volume of HEPA filtered air over the life of the HEPA filter. This is critical in applications where certain air filtration exchange rates are required to maintain a clean room level class 100 or 1000 for the specific application.

The other advantage with ECM motors is their ease of modification to operate in any voltage anywhere in the world. These motors are rated 120/240 volt 50/60 Hz and with a simple wiring change the motors can be swapped to work with either voltage. This made it possible for Pure Air Systems to sell their units anywhere in the world without making any changes to their equipment’s electrical components.

More Than A Feeling

It is often said that people don’t want to hear you complain about issues and things that bother you on a regular basis. With the ability to express your every thought using social media, your issues are now broadcast around the world. Yes, everyone wants to vent about something and everyone hopes someone else will jump on their complaint band wagon.

However, when we do have a legitimate issue, especially one pertaining to our health, we do want someone to take our complaint seriously and not reject it as another “boy who cried wolf” emotion.

For 31 years Pure Air Systems has been selling their HEPA based air filtration systems to a wide range of customers including medical, institutional, industrial and residential. A large number of residential customers suffer from allergies or respiratory dysfunctions brought on by ingesting sub-micron airborne allergens and various types of particulate matter. Because the airborne particles are too small to see with the naked eye, when someone in the house or office complained about their severe reactions to the environment most people disregarded their complaints and paid little attention.

But for allergy sufferers and those individuals who really have issues with airborne molds and other building generated airborne contaminants these issues are real and can cause significant long-term health issues. It is ironic the the particles that tend to be trapped in the lung linings and mucus membranes are too small to see yet cause much more damage than the larger, visible airborne particulate that are aspirated in then out again.

The ability for the commercial grade, scanned HEPA filters, rated at 99.99% efficiency, to remove over 97% of these small, sub-micron particles is the reason people continue to purchase the PAS units over other types of filtration devices or systems. With over 31 years of experience in this arena, Pure Air Systems has become a major supplier of high-end, high performance, fan powered HEPA filtration systems.

Why HEPA Filtration Is The Best

HEPA filters are designed to remove a very high percentage; more than 99.97%, of all particles 0.3 microns in size or larger. In truth they are actually more efficient than that as they become dirty they actually increase in efficiency. This is true of most mechanical filters but HEPA media starts out at an efficiency that is higher than the general duty filters that you use in your HVAC systems after they are fully loaded.

HEPA filters are the ONLY filters used in Hospital Surgery Suites, Clean Rooms, the CDC and any application where the the removal of sub-micron particulate is an absolute necessity. You would be in serious trouble if you have your body was opened up in an environment such as you bedroom. Even if you think it is clean, it is not. Airborne pathogens are a constant cause for infection and having surgery in anything but a 100% HEPA filtered room is asking for trouble.

While HEPA filters are extremely effective in trapping sub-micron sized particles, they are also extremely dense and have a fair amount of air-flow restriction. As a result, larger, more powerful motors and specially designed fans are required to pull the air through the HEPA filter. And, as the HEPA loads up the fan motors must be able to increase in speed to make up for the air flow volume loss that takes place as the HEPA becomes dirty.

Because HEPA filter media ( wet laid HEPA paper ) is so dense it will load up very quickly, a pre-filter media is required in front of the HEPA filter to capture as much of the larger particles as possible and only allow the very small, sub-micron particles to enter the HEPA filter. Without the use of a pre-filter a HEPA filter could load up in a few days and make the HEPA useless.

HEPA filters are available for use in the residential markets through companies such as Pure Air Systems out of Indianapolis, IN. In business since 1985, PAS is the leader in fan-powered HEPA based air filtration systems and they range in capacity from 50 CFM to 2000 CFM. These metal housed units also use variable speed drive motors  ( ECM ) that are rated 120/240 50/60 Hz so they can be used anywhere in the world.

RAMBO

Of all the roles played by Sylvester Salon, Rambo is probably my favorite. It is a mixture of his Rocky character…slow spoken with deep honesty in his eyes, and his Expendables character where killing and maiming are often done with some weird humor. And of course, he faces numerous bad guys and barely gets scratched. Or if he does he has amazing healing powers.

Some companies have this same character trait where they keep the best parts of their operations as they move forward with new technologies and marketing concepts. In this way the customers still feel like they are dealing with the same people even though the company logo, location and product design are changing.

Pure Air Systems started its operation in 1985 with the promise that they would produce the highest quality products and offer superior performance and exceptional customer service. Fast forward 31 years later and Pure Air Systems still makes the same great HEPA based, fan powered air filtration systems in North America and have added a few new products along the way.

The PAS line of HEPA and Carbon filters use the newer variable speed ECM motors that can be digitally controlled producing air volumes from 50 CFM to 2,000 CFM in one percent increments if necessary. These systems can even be designed to work in series with ducted HVAC systems.

These units are used in almost every application with the reduction/removal of airborne contaminants at sizes below 0.3 microns in size. In fact the newer scanned, certified HEPA filters can remove 99.99% of all particles 0.3 microns and larger, consistently.

PAS has units in the commercial, medical, agricultural, industrial, institutional, military and residential markets. Some of them are even operating on ocean going vessels. Used as stand-alone or connected to your heating/cooling/ventilation systems, the HEPA systems from PAS are the most effective method for airborne contaminant control.

High Speed Rail

The world has to move billions of people every day from one place to another and it does it via numerous modes of transportation. Car, truck, bus, bike, motorcycle, boat, plane, train and even camel. Other than planes, no other mode of transportation is as fast or efficient as high-speed rail.

Bullet trains are common place in Japan and some other parts of Asia. Moving at speed up to 300 miles per hour, people can make one hour trips that used to take 4 to 6 hours using vehicular modes of transport. In addition, these trains carry as many as 500 passengers making this a very effective method of moving a lot of people quickly with minimal energy used per passenger.

Speed is important in other businesses as well. Pure Air Systems has been delivering high-speed, high performance HEPA based, fan powered air filtration systems since 1985. The ability to move a large amount of air ( CFM ) to effectively remove harmful airborne contaminants separates the PAS systems from the rest of the filtering devices. With the ability to move up to 2,000 CFM at long distances, the PAS products are capable of being used in a wide range of applications in the residential, commercial, institutional, industrial, medical and military.

These all metal units use the ECM variable speed motors that are rate 120/240 v 50/60 Hz so they can be used anywhere in the world. And, they incorporate not only a 99.99% scanned, commercial grade HEPA, but also a dual layer prefilter and carbon media filter as standard components.

There is a significant move to making all the health care facilities safer and using more of a defensive posture to reduce the level of airborne pathogens, viruses, bacteria and other harmful sub-micron sized particles. PAS is playing a major part in assisting your local health care facilities by using our systems to provide for isolation rooms and areas to separate infected people from the general population. These systems also help to protect the health care workers.
