Variable Speed Drive Motors VS Induction Motors

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 41 Year History

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.

Understanding Indoor Air Quality

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.

The Arrow of Time Theory

In essence, the Arrow of Time Theory states that we tend to look at future technology and processes by carrying things from the past and putting them into these future ideas and concepts. This is very limiting as it tends to eliminate advanced or out of the box thinking with the resulting new concepts having parts of our old thinking linked with them. This type of thinking is doomed for failure.

Today, the advancements being made in AI, Robotics, Additive Manufacturing, Electric Cars, and Space Exploration are changing and will change forever the way the world works. These advancements are, in part, designed to minimize or eliminate the use of human labor is areas where the work is dangerous or the ability to significantly reduce the amount of labor needed to do menial tasks. Electric cars area already making major inroads in the global market and AI is now being used in almost every facet of design, marketing, product development , medical and governmental operations. 

While many people worry about the speed of change, these new concepts and technologies will actually speed up both the speed of change but also the adaption of these new technologies. This is necessary for our civilization to thrive and survive.

Meeting The Unbelievable Expectations of Customers

Have a customer who thinks they know more about your product than you do and can site facts from 20 years ago to prove it? And, they want answers to un-answerable questions? Welcome to the new world of main street business. Yes, customers can be down right nasty and intractable and it is getting worse. This is not always the case, but if you are dealing with a more senior individual there is a better chance of having a major discord with this individual.

One of the reasons for this challenge is the fact that many people now have to either converse with a Bot on their computer or talk to an individual thousands of miles away with a foreign accent that they can’t understand.

Go back 30 years and customer service was the epitome of many companies and they touted their ability to deal with your issues like you were part of their family. And, many companies were family owned and operated or the corporations actually had compassion for their customers. Money was not the only object. Repeat business was king.

Today, you need to have a phone, computer or tablet to order, track, pay for and return any item or service. In many cases major transactions can take place  like selling or buying cars, homes, boats, etc. without ever talking to a human being. Airline reservations are done on-line as is booking hotels, buying groceries and getting your plumbing fixed. If you throw in the use of AI, there are operations where you are having a conversation with a computer generated program that is as effective as using a human being. 

Pure Air Systems got its start in 1985 with the old fashioned process of going door to door and making products that worked extremely well. Every aspect of the selling process as face to face and person to person on the phone. ( corded version) If you needed a replacement part we had it in stock and it was sent out the next day and a follow up call was made to make sure the customer was satisfied with the replacement. Extended conversations with customers on how to set up or operate the equipment were common place. There were no bar codes or QR codes to use to access a website. 

Today, Pure Air Systems relies heavily on its website to promote and educate potential customers as well as offer detailed descriptions of their line of HEPA based air filtration systems. Customer service is still done verbally via phone of email and the products are still made with the best performing parts available on the market.

Pure Air Systems Still Use All Metal Housings

Pure Air Systems began its journey in 1985 producing one of the first true, commercial grade, fan powered air filtration system that could be used in either commercial or residential applications. These units were made from 20 gauge mild steel that is powder coated for a durable, long-lasting finish. 

Today, the line up of 7 different systems made in variations in both size and air flow design are still made from the same high-grade 20 gauge powder coated steel housings now using the latest iteration of the variable speed drive motors that are digitally controlled. The HEPA filters are all 99.99% efficient at .3 microns and larger and the prefilters and carbon filters come standard with each unit. 

The HEPA Shield systems come in air flow ranges from a low of 50 CFM from our portable unit up to 2,000 CFM on our largest model 2000HS unit. These systems can also be modified to be attached to an existing HVAC duct work system or as stand-alone units. 

Pure Air Systems are all made here in the USA with most of the components manufactured in the US. Some of the original units are still in operation and the average longevity of any of the systems is better than 15 years. Making the PAS units one of the best economical purchases for any air filtration system on the market today.

How Companies Stay In Business Beyond 30 Years

Starting a business today is easier than it has ever been. Running it and keeping it a float is another. Longevity in businesses today is no longer the norm. Companies are born, merge, change direction and die faster than ever before, so having a company stay in business and keeping it on a positive revenue stream for 30 plus years is no easy feat. 

Pure Air Systems was started in 1985 by Don Musilli, and was sold in 2006. The concept of manufacturing a high end, fan powered, commercial grade, HEPA air filtration system that could be used in almost any configuration was very foreign in 1985 but the concept, the quality and performance of the systems allowed us to continually increase our market share.

Over time, Pure Air Systems added more products to its catalog and eventually ended up with 7 different systems allowing for complete penetration into the commercial and residential markets requiring high end HEPA based air filtration systems. The addition of the ECM, variable speed motors in 1999 provided an entry into the over seas market allowing us to offer 120/240 volt 50/60 Hz motors for all of our systems.

Pure Air Systems learned that feedback from its customers was important and responding to the feedback in the way of modifications to the systems was essential in growing its business. Keeping the same quality even though prices increased was necessary as people are quick to switch companies when something doesn’t work like it should. Losing customers is easy….keeping customers is hard.

Pure Air Systems is now 37 years old. That puts it in rare company these days especially for a manufacturing operation. The adage of “adapt or die” is very true today and “modifying, changing and altering” your operation to meet the changing needs of the market is critical in keeping your company moving forward and growing.

Air Filtration 101

The use of air filters for removing airborne particulates has been around for over 100 years. Today’s filtration technology is eons ahead of just using cheese cloth to filter our particles for fan powered device. The newer, blended filtration medias are much better at capturing small, sub-micron particles with higher capture rates and lower pressure drops over time.

Air filters range in efficiency from general duty, like furnace filters, to high capacity, high efficiency, like HEPA filters. For most home applications the general duty filters are used as they both help keep the cooling coils in the HVAC system clean as well as minimize the dust in your home. 

The higher efficiency filters, like HEPA, are used mostly in commercial applications like hospitals, clinics, surgery suites, chip manufacturing, clean rooms, laboratories and more. There are also HEPA based systems available for the residential market that utilize their own fan/motor system to augment the blower/motor assembly in the HVAC unit. HEPA filters have a much higher resistance to air flow but can capture particles as small as a virus. 

It should be noted, that the use of non-mechanical filtration devices such as ozone generators or electronic air cleaners are not really that effective at removing particles from the air. Ozone generators are really more effective on the reduction of airborne gaseous contaminants and electronic air cleaners need constant cleaning to make them work.

Time To Consider Whole House Air Filtration

For most home owners, having an air filter in the main return air duct next to the HVAC fan system or separate filters in the numerous return air outlets in the rooms of the house, constitute whole house air filtration. 99% of these filters are general duty filters that are capable of removing very large airborne particles and not adding any static pressure load to the HVAC fans. The compromise here is that you are trading air flow for not so good air filtration.

In 1985, Pure Air Systems introduced a new HEPA based, fan powered air filtration system that would provide a much higher level of removing much smaller airborne particulate including bateria and some viruses. By using a concept called, partial by-pass system, PAS can attach their HEPA units to the return air side of the HVAC ducting system and because the PAS systems have their own fan, they will not impede the performance of the main HVAC blower/motor assembly.  In addition, the PAS units also incorporate a prefilter and carbon media filter for removal of odors and gaseous pollutants. 

Since the inception of the partial by-pass concept, PAS has sold thousands of these units to home owners across North America and has even placed some on board ships and in the hospitality industry. This concept is easy to install and can be retrofitted on existing, ducted HVAC systems in any application.
