Chevrolet Nova – A Car After It’s Time

The Chevy Nova was made in the early 60’s through part of the 70’s and was somewhat popular as a mid sized, low cost vehicle. This car also had many mechanical issues and was dropped from the line up only to be resurrected as the Chevy Citation in the 80’s. Different design, same issues. When the Japanese entered the US car market they were surprised that General Motors ad chosen the name Nova because in Japanese this word means NO GO. This should have been a warning to GM not to use that name.

When Pure Air Systems came out with their HEPA filtration systems in 1985, the units were considered too expensive and the existing furnace type media filters were considered the best filters on the market. Ozone generators and Ion Generators were also sold as high efficiency air filter systems and were much less expensive than the HEPA units. However, like the Nova, these general duty air filtration filters and mechanical systems did not work as promised and are still sold today to unsuspecting consumers. 

The fan powered, commercial grade HEPA filtration systems by PAS are considered some of the best overall HEPA systems on the market. And, Pure Air Systems, Inc. is one of only 3 companies in the world that make this type of HEPA system with a wide range of sizes and housing configurations. The PAS line offers systems that range from 50 CFM to 2000 CFM using new ECM variable speed drive motors.

Blockchain Filtration

Blockchain technology is in the news everyday and unless you have been hiding under a rock all you hear anymore is Cryptocurrency, Bitcoin and Blockchain. The advantages of using the blockchain process for storing data is the ability to have a secure set of data that cannot be changed or altered making it a very unique method of storing all types of encrypted data including Bitcoin.

Pure Air Systems has been manufacturing HEPA air filtration systems since 1985. Their fan powered commercial grade systems utilize a three-stage filter system. The first stage, is a dual-layer polyester ring panel filter. This captures much of the larger particles and protects the carbon filter and HEPA filter that follow. The carbon media unit that follows the prefilter, captures airborne gaseous pollutants. Lastly, the 99.99% scanned commercial grade HEPA filter that follows the Carbon filter captures over 99.99% of all particles 0.3 microns in size and lager.

As with the Blockchain technology, the three-stage filtration process used by Pure Air Systems in all of their systems capture all the particulate and retain it in their air filter components forever. HEPA filters are the primary filtration technology used by the CDC, hospitals, clinics, surgery suites, and the reduction/removal of airborne viruses such as the Covid-19 strain.

Tobacco Road

In the 60’s Eric Burton of the rock group The Animals sang a song about a lost soul. The name of the song was Tobacco Road. The animals and song went on to become an iconic part of early rock and roll. Along the same lines the product tobacco had also become one the most influential soft drugs in the US and around the world. Nicotine, one of the main components of cigarettes and other tobacco related products, is also one of the most addictive compounds legally allowed in every country in the world.

In addition to the nicotine that is harmful to the user, the cotinine that is released as a result of burning the nicotine is a sticky material that sticks to everything it touches and releases an odor that lingers for a long period of time. Attempting to remove this airborne gaseous compound is difficult as it requires both carbon for adsorption of the odor as well as filter media ( usually HEPA filters) to capture the very fine airborne particulates that are released by the cigarette.

Because of the nature of the two emissions both the carbon and media filters ( HEPA ) need to be changed frequently making it very expensive and challenging to remove cigarette smoke in a room or enclosed area. This is one of the major reasons whey smoking is now prohibited in almost every public building and most restaurants.

Creating The Portable Clean Room

Creating a room that meets the criteria considered class 1000 ( maximum of 1000 particles per cubic foot at 0.3 microns) usually requires special construction and an air handler system that includes HEPA filters and a motor/blower system capable of moving 2,000 CFM or higher of filtered air in a positive pressure environment. This design is both expensive and takes a fair amount of time to construct.

Using one of the larger HEPA Shield systems, made by Pure Air Systems, would provide a system that could be easily convert any room into a clean room or temporary surgery suite. The 2000HS unit comes with a 1HP programmable, variable speed drive motor, prefilter, carbon media filter and true, commercial grade 99.99% scanned HEPA Filter. The 2,000 CFM unit can be placed in the ceiling area or along the top of a wall attached to sections of sheet metal ductwork with diffusers located in various parts of the ceiling area. When the unit is operational it will be pushing 2,000 CFM of filtered air into the enclosed space. This will pressurize the room so that when a door is opened into the room the air will move out of the room creating a positive pressure seal of sorts. In this way no airborne contaminants are allowed to enter the room. 

This concept has been used in third world countries where almost any building can be turned into a quasi-clean room or semi-surgery suite for under $3,000.00. In addition, all of the filtration systems from Pure Air Systems are rated at 120/240Volt 50.60Hz.making them suited for any location anywhere in the world.

High Performance HEPA Portable By Pure Air Systems

Pure Air Systems has been making commercial grade, fan powered HEPA air filtration systems since 1985. They are one of three companies in the world that provide this type of filtration systems. PAS makes a number of models of HEPA systems that range from 600 CFM to 2000 CFM all using variable speed drive motors. Their portable system, the HPS series was introduced around 1992 and has since gone through a number of refinements. It was the only HEPA unit in the line-up that did not use a variable speed drive motor. In stead, it used a 4 speed motor from EBM. 

Coming this year, PAS will be fitting the popular portable HPS unit wiith it’s own variable speed drive motor. This will allow for a CFM range from 25 CFM up to 250 CFM in 1% increments. In addition, the new motor will be designed to maintain the same speed/cfm rating even as the pressure drop increses across the HEPA filter.And likes the original version, the new HPS unit will have a prefilter,carbon filter and a true 99.99% scanned HEPA fitler as standard equipment.

The portable HEPA unit has a wide range of applications and is very well suited fror the laboratory environment as well as small confined areas requiring HEPA filtraiton in both a positive or negative room application. The all metal housing and rugged construction make this one of the best portable HEPA systems on the global market.

Pure Air Systems Is Major Supplier Of Filtration Systems To Fight Covid-19

Created in 1985, Pure Air Systems was one of the first US companies to offer commercial grade, fan powered, HEPA air filtration systems for the general publc. These systems are designed to be used as both stand-alone units as well as attaching them to existing HVAC systems to provide central and whole house filtration. Over the next 10 years Pure Air Systems developed seven different sizes and configurations varying in air volume capacity from 50 CFM to 2,000 CFM. In addition the systems had the capacity to add carbon media and prefiltration in conjunction with the HEPA filters providing systems that could handle almost any air filtration or odor challenge in the market.

When Covid-19 entered the globe in eary 2020, many of the hospitals, clinics, laboratories and municipal facilities across Norht America started lookng for HEPA based air filtration systems as HEPA filters are the only type of air filter that can remove a subtantial amounty of airborne viruses. Standard air filters are, for the most part, not very effective in removing these sub-micron particulate from the air. 

The Pure Air Systems units use very powerful, variable speed drive motors ranging from 1/3 HP to 1 HP, they can move a lot of air through the HEPA filters which are extremely dense. In additon, the units can move air through ductwork that is connected to the filtration systems so they can be used to provide clean air in a large space. The systems can also be used to create either a positive or negative room area for patient isolation as is the common practice in most Hospitals.

Today, Pure Air Systems is one of only three companies around the world that produces a metal framed, commercial grade, fan powered true HEPA air filtration that can be used in a very wide range of applications in the residential, commercial, institutional, industrial and medical markets.

Mechanical VS Electronic Air Filtration Systems

Most people are familiar with the air filters that go into your HVAC system that look like folded or pleated paper media. These are normally refered to as mechanical filters because they use the mechanics of air velocity to impinge the airborne particulater onto the surface of the filter. Electronic air filters use positive – negative charging as their method of collecting these same particles. These electronic air cleaners use plates for wire grids to trap the particles but unlike mechanical filters, are less efficient than mechanical air filters as they allow for much of the particulate to pass by the collection grids without capture. For this reason mechancial air filters are the preferred method of dust collection.

Air filters perform two major functions in HVAC systems. One is to keep the dust from accumulating on the cooling coils in your air handler to ensure proper performance of you air conditioning system. The second is the removal of airborne particulate in the air to keep the indoor environment cleaner. These mechanical air filters come in different efficiencies from general duty up the high efficiency HEPA air filters.

The use of very high efficiency mechanical filters including HEPA sysems is now extremely important due to the need to remove airborne bacteria and viruses during this pandemic. Schools, office buildings, and all medical faciities are using mechanical air filters with higher efficiency ratings to contain the airbone contaminents as much as possible.

Do UV Lights Really Kill Covid 19 ?

Ultra Violet lights (germicidal lamps) or UV systems come in both a hot (8,000 hours life) and cold plasma (rate 36,000 hours life) lamp systems. They produce a specific wavelength of 253 nanometers and produce UV C. This wavelength has the ability to affect microbiological contaminants like mold and bacteria. The UV C light can destroy the DNA of the microbiological and keep it from replicating. UV C has no effect on solid particles and it does NOT remove anything from the air stream. UV C lights are normally placed in the return air stream, although the speed of the air past the lights can minimize the effectiveness of the UV lights. We suggest that placing a UV light at or near the cooling coils works better as the light can irradiate this moist area all the time and help in minimizing the growth of mold or bacteria. UV lights are an ancillary piece of equipment and should always be used in conjunction with an air filter or air filtration system.

The Use of UV lights to reduce or kill Covid 19 viruses is somewhat limited to the distance to and the duration of time it sees the virus. That is why UV lights are more effective placed in the return air duct of the HVAC system and the fan has to be running all the time. Further more, you need really good filtration in front of the UV lights otherwise they will become coated with dirt and dust and thus significantly reduce their effectiveness.

If you look at the miriad of photos and TV footage of Hospital wards treating Covid 19 patients, you never see any UV lights in and around the patient beds. Sterilaztion with chemicals and the use of PPE are much more effective in that area of the hospital. The real danger in using UV lights is the thought that this technology is a primary method of eliminating the Covid virus when in truth it is  only a terciary device at best.

Pure Air Systems has been making HEPA based air filtration systems for over 35 years and today the use of HEPA filters has become the primary method of maintaining surgery room cleanliness in Hosptials, Clinics and laboratories all working with Covid. 19.

Using HEPA Fan Powered Systems For Virus Protection

Keeping employees and customers safe in buildings, stores and other enclosed spaces will be a major part of returning to the new normal. Aside from making desks and work spaces at least 6 feet apart the ability to maintain some form of control over the ventilation systems would be the next major hurdle. The standard HAVC system in residential and commercial building is designed to move the air through return air and supply air ductwork and keep the room cool or warm. The types of filters normally used in these systems are what we call “general duty” air filters. Meaning they will remove large particles, dust and some smoke, but are not really capable of removing anything close to the size of viruese which are down to .005 microns in size. Basically a billionth of an inch.

Pure Air Systems has been making fan powered, commercial grade, HEPA air filtration systems since 1985 and has seven different configurations and air volume sizes to meet most needs in the commercial, institutional and industrial markets. Since its inception, PAS has provided a unique adaptation of their systems so they can be used in a partial by-pass configuration. This allows the HEPA systems to be connected to the main return air duct in a partial-connection taking a portion of the return air and putting in through a 3-stage filter system including a prefilter, carbon media pack and a scanned 99.99% HEPA filter. Using this concept allows for partical cleaning of the air continuously without affecting the performance of the main air handler. In most cases all the air in the room would be filtered once every 30 minutes to an hour. In addition, it is possible to add small amounts of outside air into and through the PAS unit prior to entering the main air handler which helps to pressurize the room area and also dilute the inside air. The small amount of air that is added from the outside does not really affect the temperature since the percentage is usually around 3% to 5 % of the total volume of air being cooled and or heated.

The systems offered by Pure Air Systems range in CFM volume from 50 CFM to 2,000 CFM. These systems all use variable speed motors and are digitially controlled. They are made from components all made in the USA and assembled in Indianapolis, IN.
