A very large number of appliances and motorized equipment that we use utilize electric motors. Some are very tiny and they run small appliances and consumer products like 3D Printers and grinders. Most of these are induction type motors that may have some form of speed controller or are just on/off motors. And, many of them are designed for single voltage use, meaning they are either 120 volt 60 Hz or 240 volt 50 Hz ( like those in Europe ). 

In 1998 General Electric developed a new motor that incorporated a magnetic drive system as opposed to a copper wound motor. These new motors could run forwards or backwards and would operate on 120/240 Volt 50/60 Hz current. First, this allowed them to be used any country in the world and secondly opened the door for development of a wide variety of new devices for many equipment manufacturers. 

In addition to being able to run in both directions, they could be controlled to run at increments of 1% to 100% in 1% increments making them extremely viable for applications where finite speed control was required. In addition, these motors can now be programmed to speed up or slow down based upon the performance requirements of the equipment. For example, if the motors are being used on systems that require different speed profiles for various performance requirements. These new motors can now also be operated by using a App on your phone so they can be controlled from any distance as long as there is wifi available. 

Pure Air Systems, an Indiana based corporation, has been using these new motors in their HEPA based, fan powered air filtration systems since 1999. PAS was one of the first companies to incorporate these motors into their systems replacing the standard induction motors. The new motors provided an entry into the European market and created an entirely new market for these air filtration systems. They could now be used both attached to existing HVAC systems with the ability to match the airflow requirements and also as stand-alone units where air filtration was needed in non-conditioned space.

Pure Air Systems was founded in 1985 with the specific intent of bringing commercial grade HEPA based air filtration systems to the residential and industrial markets. Over the years PAS developed 7 different system configurations that could either be attached to an existing HVAC system or used as stand-alone units. 

Over the years PAS has improved its air filtration systems by incorporating programmable variable speed drive motors that can now be operated with an app on your cell phone. This allows for infinite air flow adjustment for best filtration efficiency and performance. This process provides a unique advantage of using the PAS line of HEPA filters over all the other competitors in the market. In fact, Pure Air Systems, Inc, is one off only 3 companies in the world that make this type of air filtration system.

The PAS HEPA systems use all metal housings and can incorporate a variety of filter types in their units. These include the scanned 99.995% HEPA filters, carbon media filters and ring panel pre-filters. The system range in air flow capacity from a low of 50 CFM up to 2,000 CFM for the larger units. The systems can be used strictly as odor or gaseous removal systems by using just the pre-filter and carbon media filters without the HEPA. This makes these systems extremely flexible as they can be modified in the field with different filter arrangements in a matter of minutes.

No matter how you may feel about the Covid virus issue, there is a new variant that is quickly moving through the US. Viruses will mutate rapidly to stay viable even though there are a number of vaccines now available for the general public. One of the major reasons these viruses stay active is the fact that people that have this virus and are coughing or sneezing and they often mis-diagnose this as a cold or allergies or sinus issues. So, they continue to congregate with other people at work or school and the virus spreads faster.

Pure Air Systems has been making high end, commercial grade HEPA based air filtration systems that are specifically designed to remove bacteria and a high percentage of viruses. Viruses are extremely small and are impossible to capture with general duty air filters. HEPA filters are designed to capture 99.99% of all particles 0.3 microns and smaller. These particle sizes are invisible to naked eye so it is impossible to see them when they are airborne. 

PAS make a wide range of sizes and air flow capacities for any application. The fan powered units can be used either as a stand-alone unit or attached to an existing HVAC system. The systems can move anywhere from 50 CFM to 2,000 CFM depending upon the requirements. Also, these units use variable speed drive motors with speed adjustments from 1% TO 100% in 1% increments. And, they can be adjusted from an app on your phone. PAS also makes a small portable unit that can be taken with you in you car if you travel and stay at a hotel or motel and are visiting family members.

Tesla has been incorporating true HEPA filters along with standard filters in all of their cars and the Cybertruck. These are installed as a method of both keeping hazardous particulate from entering the interior of the car and maintaining an allergy free environment. They even have a setting in case there is a nuclear incident where the car maintains a sealed off interior from exterior elements. 

HEPA filters have been around for many years and were first developed during the initial phases of creating the bombs used on Hiroshima. These specially designed filters utilize a special wet – layed paper like material that is extremely dense. It is then folded into an accordion style format to allow for greater filter surface area in a small envelope. Most HEPA suppliers use either aluminum or glues to keep the pleats separate and rigid. These HEPA filters come in various sizes to fit a wide variety of applications including medical, chip manufacturing, clean rooms, surgery suites, pharmaceutical manufacturing and some food processing applications.

HEPA filters are relatively expensive and usually come in a metal frame or stiff cardboard frame for some applications. The Tesla HEPA filters use a stiff paper frame to allow for some flexibility in inserting the HEPA filter into the appropriate slots. The normal life of the HEPA in the Tesla is approximately two years as the HEPA is preceded by a general duty filter to keep the HEPA clean and only allow the very tiny particles to enter the HEPA.

Pure Air Systems has been manufacturing HEPA filter systems since 1985 and is now only one of three companies in the world that make a fan powered, commercial grade HEPA system that includes prefilters and carbon media along with the HEPA. These units range in air flow capacity form 50 CFM to 2,000 CFM and use variable speed drive motors that are programmable and can be operated remotely from a phone app. For more information on the complete line of HEPA systems please go to our website at;  http//:www.pureairsystems.com  or call us on our toll free number at:  800-869-8025.

HEPA filters have been around for a long time and they are used in a wide variety of applications including hospital surgery suites, commercial air filtration applications, cars, homes and in AI chip manufacturing. These filters are unique, in that they are made from special fibrous paper and extremely good at removing particles in the air is sizes down to .01 microns with efficiencies approaching 99.99999%. 

There are various grades of HEPA filters. The standard HEPA filters are effective down to 0.3 microns at 99.99% and are capable of removing all bacteria and some larger viruses. There are ULPA HEPA filters ( Ultra Low Particulate Air ) and SULPA  HEPA filters( Super Ultra Low Particulate Air ). These HEPA filters are normally used in Clean Rooms where the elimination of 99.99995% of all particles .01 microns and larger are required. To give you an idea of how small this is, your hair is about 100 microns in diameter. Also, you can only see down to about 20 microns with the naked eye. So .01 microns is very small. 

Over the past 30 years, HEPA filters have been incorporated into many air filtration devices and systems. Pure Air Systems, Inc. developed a fan powered, HEPA based air filtration system in 1985 that used the standard HEPA as its base filter. The company has seven different systems with air flows in the range of 50 CFM to 2,000 CFM. These are all metal housings using programmable variable speed motors that can compensate for the increase of static pressure across the HEPA filter and automatically maintain the required air flow for the applications. These are also capable of being operated by an app on your cell phone.

It’s time to stop over thinking how AI can affect your business world and actually begin to understand its’ uses and how it can give you the advantages to grow your market and modify your product line to keep pace with the rest of the world. If you think the world is moving too fast you are wrong. You are about to be overwhelmed with a new Process Interruption that will affect everything you do.

The incorporation of AI and AGI along with autonomous robots, cars, trucks and are changing the way companies plan their new product lines and look at incorporation of these technologies to minimize labor costs ( and labor ) and expand their operations globally. Unlike new products like computers, iPhones, and the internet, you will not have 3 years to adapt to the new technology. This is a NOW technology. Your competition is already using it and aligning themselves with companies and products that will enable them to be in the fore front of their industries. 

Pure Air Systems, a manufacturer of high end, commercial grade HEPA and Carbon based air filtration systems, has been in business since 1985. This Forty year old company has been modifying their systems over the past few years and incorporating more AI technology to enhance both their equipment design and remote operations controls. They are now one of only three companies in the world that still make this type of equipment and they are constantly trying to stay in the fore front of new technology.

The advent of the new tariffs being applied to a number of countries by the new administration are significantly affecting the US manufacturing complex as many parts, assemblies, products, chemicals, clothing and retail items come from outside the U.S. These additional costs, in many cases, can not be absorbed by the US companies so the extra costs are passed along to the consumer.. These additional costs, along with the current rate of inflation, have proven to be a real burden on the American public. Food prices are also at a all-time high and the rise of imported food products is part of that issue.

For companies like Pure Air Systems, Inc, that manufacturing high end fan powered, HEPA based air filtration systems, the additional cost of importing their HEPA filters and some of the electronic components for their remote controlled systems, has created a challenge. While PAS, is a highly specialized company, their customer base, of which 50% are retail customers, are somewhat hesitant to pay the higher prices for their systems. The commercial customers are still buying but waiting longer to make purchasing decisions. 

The high end, commercial grade HEPA filters are currently coming from Turkey, and they meet the specifications and delivery time for the PAS production process. Going back to a US vendor would delay production as going back to a US supplier would require renegotiating the purchase and delivery time table. 

The other issue, is the length of time these tariffs may be in place. Part of the rationalization for the tariffs is bringing manufacturing back to the US. However, as we have seen, this is very difficult to do and there are few companies with the capabilities to match the in-place production facilities that now exist everywhere in the world.

Everyday there is information provided regarding the level of outdoor air quality and it’s potential affects. The levels can range from good to very poor. While some people with severe allergies or respiratory issues value this information, most people pay little attention to these outdoor air quality warnings because most of us are indoors the majority of our time. Either at home or work or both. And we believe that being inside is much safer and healthier. And nothing could be further from the truth.

Indoor air quality is maintained, primarily, by the HVAC systems that both heat and cool the interior spaces. These systems recirculate the air with very little fresh air being introduced into the home or building creating a somewhat stagnant indoor air environment. The air filters that are used in most HVAC systems are general duty filters designed to capture very large dust particles that are airborne. These filters don’t capture bacteria, viruses or various forms of allergens. This means that all the airborne particulate are being recirculated throughout the interiors spaces for everyone and anyone to breathe. 

Most new homes are now designed so that when the HVAC units are running the home is under positive pressure, meaning no outside air is being introduced into the interior spaces. While this keeps the home warmer in the winter and cooler in the summer, the lack of outside fresh air creates a very unhealthy indoor environment. But there are solutions to this problem.

Pure Air Systems has been manufacturing HEPA and Carbon based, fan-powered air filtration systems since 1985. This US based company makes a line of systems that can be attached to the return air side of your HVAC unit and because they have their own fan assembly, they can be installed to introduce small amounts of fresh, filtered, outside air into the home or office. Since the HEPA filters are designed to capture bacteria and many types of viruses along with other allergens, The PAS units provide the perfect solution to keeping the air in your home or office clean and fresh.

Since it’s beginnings in 1985, Pure Air Systems has strived to push the limits of available technology to continue to improve its HEPA based air filtration systems and offer more operational flexibility for its commercial and residential customer base. During the early years of operation PAS used the common induction motors for their systems. These were limited to one speed and limited the amount of volume adjustment in the filtration systems. 

In 1999, GE produced a new variable speed drive motor known as an ECM motor. This motor was a total departure from the wound copper induction motors as it use magnets for its drive mechanism. It could run forward or backwards and could be controlled digitally to operate in 1% increments from % of volume to 100% of volume. PAS was one of the first companies in the US to test this motor and eventually incorporate it into all of our systems. Additionally, these motors could be used in 120/240 50/60 Hz applications, making them perfectly suited for use overseas where most electrical systems are 240 volt/50Hz. This allowed us to open up new markets in Europe and Asia.

In the past year the the 2nd generation of these motors now allows us to operate them using Bluetooth apps on any smart phone. This gives the customer complete control of the HEPA systems no matter where they are located. And, the new motors can be programmed for different HP requirements from 1/3 HP up to 1 HP and run at full speed even when the pressure drop across the HEPA filters gets as high a 3.3 inches of static pressure.

Beginning in 2006, many of the major manufacturers in the U.S. decided that labor costs were too high here and that competing with overseas companies required a different strategy. The companies shipped both their R&D and Manufacturing operations overseas. Mostly to China and Indonesia. Some had offices in those area but those were absorbed by the other countries. This also included the tech industries who required employees with specialized skill sets and allowed did design the products here but had them made in China.

With the advent of Amazon on the scene, the American public began purchasing items based on cost not on where it was made. Today China makes over 65 % of the products we use in the US and some are now made in Vietnam, Cambodia, India, Ireland and Mexico. In addition, the vast majority of high end electronics now also come from Japan and South Korea. You can’t purchase a TV made in the U.S.

Manufacturing is a very difficult and expensive process and building new plants requires a few years of investment with little profit. So, while many people believe that the new tariffs will change that equation, they are not dealing in reality. Also, any new manufacturing  visa-vie Tesla, will be done using the robots now being produced in the U.S and overseas. People are too expensive and we no longer have the skilled technical labor to create this companies. Even Apple has admitted that the labor costs in China are no longer cheaper but the highly technical manufacturing processes they now have in place are far superior to what we have in the U.S.

Pure Air Systems, Inc., a U.S. based operation makes some of the most sophisticate HEPA based, fan-powered, digitally controlled air filtration systems on the market and is now only one of three companies in the world that still make that type of product. PAS has had to purchase some of their components from overseas operation because they are no longer made here but continues to use as much U.S. made components as possible for their product line.
