In the industrial market there are a number of companies that produce batteries that contain components manufactured from lead. While the technology of producing batteries is changing rapidly there are still many operations that use lead.

Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.

To produce the lead or when shaping or casting the lead, the particulates that are emitted are extremely dangerous when ingested into the body either through contact with the skin or inhaled.

Plants that make or use lead have their employees wear special clothing and wear respirators whenever they are in areas of lead production. These precautions are necessary as lead dust is very fine and will find its way to any part of the building or structure.

Pure Air Systems, a manufacturer of commercial grade HEPA filtration systems since 1985, has installed many of their 2000HS Plus units in plants where lead is made or utilized in production. In many cases the fan powered HEPA units are located in employee changing rooms or offices within the manufacturing complex.

These filters remove 99.99% of all particles .3 microns and larger and the use of variable speed drive motors allows for finite control of air volume from 50 CFM to 2000 CFM in one percent increments. This provides the correct movement of air for the application.

For example, when the changing rooms or offices are unoccupied the units can run at 30% of volume. When the employees are in the rooms changing out of their protective garments the fans will run up to 100% of volume so that any dust that is thrown into the air during changing is quickly removed.

Pure Air Systems has been in the Air Filtration business since 1985 and has successfully kept its position in the HEPA based air filtration market by continuing to make advancements in its product line.

Since its’ beginning, Pure Air Systems has pushed the envelope in bringing HEPA based air filtration technology to the residential and commercial markets. It was the first company to develop the partial by-pass concept allow us to attach very large, fan-powered true HEPA systems to any forced air ducted heating/cooling systems.

In the later part of the 1990’s we were one of the first companies to use the new variable speed drive, ECM motors from GE. These motors were digitally controlled and they were rated 120/240 v 50/6h0Hz. So we could sell our filtration systems anywhere in the world. This opened up a whole new market for Pure Air Systems.

In 2001 we began working on the HPS portable HEPA unit. This small HEPA system used a four-speed EBM combination blower/motor and had a 12″ square housing that was 21″ long. It was designed for Laboratory applications as well as small rooms and offices. This was the first portable to use a scanned HEPA filter rated at 99.99% at 0.3 microns. It also included a carbon media filter like all of our other systems utilized.

The addition of the ECM motors also allowed us to develop some digital speed controllers that would give our customers the ability to use the systems in a stand-alone configuration and control fan speed from 1% to 100% in 1% increments. This opened up the door for applications where customers wanted to control the air flow for positive and negative room conditioning or where the application required a specific volume for proper ventilation or contaminant capture.

Pure Air Systems continues to use all metal housings for their Air Filtration systems and these powder-coated housings are designed to last up to 20 years and longer. We still have systems in the field that have been running since the late 1980’s.

The word negative is always associated with something bad or the lack of something good. It is the opposite of the word positive.

In the world of minimizing contact with harmful airborne contaminants the word negative is often used in conjunction with negative air pressure, or making a specific room or area negative.

Hospitals have rooms where they isolate a patient that has a highly communicable disease where the air in the room is constantly being filtered through a HEPA based air filtration system and air handler. The pressure in the room is slightly lower than the air outside the room so when the door to the room is opened all the air moves into the room thus keeping any airborne pathogens from escaping the room.

Negative pressure rooms are common at the CDC in Atlanta and in R&D labs around the world where highly toxic or corrosive chemicals and materials are used for product development. These rooms use both HEPA and Carbon or other adsorptive materials to remove airborne particulate as well as gaseous pollutants.

Pure Air Systems, based in Indianapolis, Indiana manufactures high end, commercial grade HEPA and Carbon based, fan-powered air filtration systems which are used in many of these negative room applications. Their systems can move from 50 CFM up to 2,000 CFM of air through the scanned HEPA filters where in many cases the units themselves are the only air moving device creating the negative pressure.

These systems can also be attached to or be part of the air handling units working in conjunction with cooling and heating systems.

In many instances homes can be under negative pressure when the HVAC system is not properly balanced making the home slightly negative which in this case is bad. That means every time the air handler fan comes on the house tends to draw some air in from the outside which means you are bringing in warm, moist or cold air all the time. Getting your HVAC systems balanced is recommended.

In 1995 Pure Air Systems purchased its existing URL. At that time there were few companies with a URL and most people had little knowledge of this digital process and even less of an understanding of what to do with the URL. Back in that era there were few websites and only Windows as a major operating system. IOS was still in its infancy.

By 1996 the internet was beginning to show some power in providing real information to a growing computer savvy public. By 1997 about 10% of all new customers for PAS were linked to our very new website that had a few photos and some text.

By 2000 almost 63% of our business was derived from customers viewing our website. We started to ask for their feedback on the information we provided in the site and made those changes accordingly. Over the years we added more products to the website then in 2007 we made a major change to the entire site.

Now, 2018, we are making another major change to the site. This will incorporate more photos and graphics with more bullet points and easy to understand information on how the filtration systems work and their applications including our Pure Air University section that provided a wealth of information on everything “air filtration.”

The website re-design should be in place sometime in May, 2018. The site is being modified by a very experienced team that has created some of the more impressive sites on the internet.

One of the main issues that will be addressed with the new website is the fact that Pure Air Systems only makes one grade of air filtration device. And that is commercial grade. There is no residential grade systems so everyone who buys one of our systems gets the same units we sell to the commercial world.

There is a long history of issues with much of manufacturing moving out of the US. For the most part a lot of the reasons were high  labor costs and corporate greed. In many cases the Asian markets had developed more companies that did injection molding and machining processes that were considerably less expensive with the ability to change product parts almost over night.

For many items imported into the US there will be little change of manufacturing venue. Technology has afforded countries around the world to make products faster and cheaper than the US. Even countries like Cambodia, Vietnam, and Thailand are now major exporters to the U.S. And, many of the companies that own these operations are U.S. corporations.

Pure Air Systems has been making HEPA based, fan powered air filtration systems in the US since 1985. Everyone of these systems has a made in the USA label on it and all the components are also made in the USA. Knowing that one would think that customers would not consider purchasing any other filtration systems. But that is and was not the case. The PAS line of high end, commercial grade filtration systems is more expensive than the closest competitor but the units are designed to run for 15 to 20 years and they perform exactly as promised. Most of the competitors use cheaper, off shore components and are not made of steel or use the high end ECM variable speed drive motors.

After 32 years PAS has proven that if you make a great product, consistently and deliver what you promise, people and companies will continue to come back and order more. PAS now offers a line of 7 different HEPA systems ranging from the small portable HPS series to our 2000HS Plus units that can move up to 2000 CFM of HEPA filtered air.

In 1985 Pure Air Systems was founded to produce true HEPA filtration systems for the residential, commercial, institutional, medical and industrial markets. The first HEPA system, the model 600H, was 16″ x16″ x 34″ high and weighed 97 lbs. That unit is still made today under the new name 600HS.

Over the years PAS made larger units to handle larger areas and applications and also develoed a smaller portable HEPA unit that is 13″ x  13″ x 21″ long and weighs 30lbs. There are now two versions of that large, portable unit.

In 2018 PAS embarked on an R&D project to develop a small, in-car true HEPA unit that also included a combination prefilter/carbon media wrap. The round HEPA filter is rated at 99.99% at 0.3 microns and will remove particles as small as 0.12 microns. The carbon will remove odors and the prefilter removes the larger particles keeping the HEPA to remove only the sub-micron particulates.

The CAR HEPA prototype is 5.5″ square and 7″ long. It weighs approximately 3 lbs and uses a small, whisper quiet fan that runs off the 12 volt plug ( or USB) in your car. PAS is also in the process of developing a HEPA Holder so you can mount you HEPA in a stratgic location for best air filtration results.

While some very high end cars ( Tesla, Mercedes and some BMW) have high efficiency cabin air filtration, most vehicles have little or none. The CAR HEPA unit will significantly reduce the levels of harmful, sub-micron particulates. These particles include bacteria, airborne allergens and some viruses.

In order to speed up the development process PAS is utilizing 3D Modeling and 3D Printing to create the housing for the unit. The first iteration took just one week to develop and now some tweaking of the housing size is in the works. It may be that the CAR HEPA will be produced on 3D Printers and they could be individualized or personalized with your name and choice of colors.

For those people who live and work in colder climates, the amount of time you spend indoors is proportionally more than those individuals who live in warmer climates. In addition colder air is much drier than warm moist air and as a result dust particles and other airborne contaminants tend to stay suspended in air for much longer periods of time.

As humans we inhale large quantities of air every time we take a breath. All of that air is filtered through our mucus membranes and lung linings and a large portion of the particulate are ( those particles larger than 20 microns ) air filtered out and most often projected out of the body when exhaling.

The smaller particles, those under 20 microns and especially those sub-micron particles, are trapped in the lung linings and not exhaled. They are absorbed by the body and then flushed out of the body. However, some of those particulate may be harmful to the body and these may be airborne viruses or bacteria or perhaps some other type of airborne contaminant. Collecting these particulate is what Pure Air Systems does with their HEPA based air filtration systems.

Started in 1985, Pure Air Systems created a line of Air Filters that specifically used true, commercial grade, scanned HEPA filters in all their systems. HEPA filters are the most effective mechanical device for removing 99.99% of all particles 0.3 microns or lager and approaching 99.98% at particles as small as 0.12 microns in size.

These HEPA systems are all fan powered and use the newer ECM variable speed drive motors so they can be used on 120/240 volt 50/60Hz electrical systems and used any where in the world.

The systems range in capacity from 50 CFM ( Cubic Foot Per Minute) up to 2,000 CFM. They can be used either attached to an existing ducted HVAC system in the by-pass configuration or as stand-alone units. These Air Filtration systems can be used in residential, commercial, institutional, medical and industrial applications.

Pure Air Systems is now 32 years old and is one of the remaining few companies in North America that still makes high end, commercial grade, fan powered HEPA air filtration systems. These systems are designed to provide true HEPA filtered air in a wide variety of applications including but not limited to: commercial, industrial, institutional, medical and residential.

Pure Air Systems makes only one type of HEPA based air filtration system so the residential customer receives the same identical system as the hospital or laboratory. These systems are designed to last a long time and run for years with minimal maintenance other than changing any one of the three filters at regular intervals.

There are a number of models available designed to fit any application and with the ability to be either installed as stand-alone units or being attached to the return air side of any HVAC system; commercial or residential.

Pure Air Systems is now the Air Apparent in this industry as there is only one other company in Europe that makes fan powered HEPA air filtration systems with the ability to handle air flows from less than 50 CFM up to 2000 CFM in a small housing configuration. In addition, the PAS units utilize the newer ECM variable speed drive motors that are rated 120/240 volt 50/6 Hz motors so they can be used anywhere in the world.

Each system has a prefilter, carbon media filter and true HEPA  filter. The systems can be configured to have all Carbon media with one prefilter for applications where only odors and gases are present. Or, they can be configured with two prefilters for applications where high levels of large particulate are present.

Our company has been around since 1985 and over the past 32 years we have seen some interesting changes in technology and the way we communicate with each other and the world. It is in the communication department that we see major changes.

PAS first had a URL in 1995. There were few ways to promote  yourself in those days and we thought being part of the Internet would be a great way to promote our products and company. Turns our we were correct.

Today, almost 80% of all our new customer leads come through our website. People can view our equipment and learn more about our products and systems and the applications for all of them and how they can be installed. But we need to go further.

Our current site is now over 6 years old and needs some fine tuning . It is not responsive so it is somewhat difficult to view on a mobile device. And since over 60% of our new views are from phones or tablets we need to change that. Also we will make the site more user friendly and eliminate some of the confusion about the differences between commercial systems and residential systems ( clue…there are none ).

We would also like to add a Chat app and be more progressive in using Facebook and Twitter. These social media platforms have become the best way to connect to everyone anywhere at anytime.

Look for a major face-lift on our site coming in February of 2018. We think you will like it a lot.

By now we all know that the Zombie Apocalypse was created through a virus developed by some unknown group. You also know by watching the documentary, Walking Dead, that the only way to put down a Zombie for good is to shoot or stab them or remove their head. So if you want to be a Zombie killer and not a member of the walking dead, then you need to pay attention to the rest of this blog. It may save your life!

Since we now know that an airborne virus is the method by which we become infected, the the obvious solution is to not breath in any contaminated air. Hard to do when the infected are now everywhere. But there is a solution. HEPA air filtration.

Started in 1985, Pure Air Systems introduced a commercial grade, fan powered HEPA air filtration system for use in homes, hospitals, schools, office buildings and other commercial facilities. Had all of these potential customers heeded our warning and installed one of our 7 different HEPA filtration models we may have to be writing about this issue today.

The HEPA systems handle up to 2,000 cubic feet of air per minute and can provide a surgery suite/clean room environment in any structure, even your home where you can hide comfortably from the Zombies.

HEPA filters are the only filtration method of significantly removing or reducing the levels of airborne contaminants at an efficiency of 99.99% at 0.3 microns and larger. They are even effective down to 0.12 microns and smaller ( virus size ) and become more efficient over time. …You are already thinking you need one aren’t you?

So, making the decision to buy one of our HEPA filtration systems is a “no brainer” if you get my drift.
