HEPA Systems For New Intel Chip Manufacturing Facilities

Intel is investing $20 Billion dollars to build two state-of-the-art Micro Chip manufacturing plants in Albany, Ohio. Chip manufacturing is done in Class 10 and Class 100 clean room facilities which are constantly being cleaned by HEPA filters with the rooms being under positive air pressure.

Chips are comprised of multiple layers and then assembled together. These layers are highly sensitive to any airborne particulate, even in the sub-micron level, as the dust particle will destroy the chips function and short it out when in use. The types of HEPA filters used in the manufacturing and assembly areas are normally comprised of a series of HEPA’s in banks. They use HEPA, ULPA and SULPA HEPA filters that will remove 99.9999% of all particles 0.12 microns and smaller. As as comparison, the Human hair is about 100 microns in diameter.

Pure Air Systems has been providing commercial grade, fan powered, scanned HEPA filters ( 99.99% at 0.3 microns) since 1985. Many of these systems have been and are being used in smaller micro chip operations, medical facilities, hospitals, military and institutional plants. The PAS systems range from 50 CFM up to 2000 CFM and can include Carbon media along with a Prefilter.

Removing Airborne Gaseous Pollutants

The removal of gaseous pollutants ( odors ) is often accomplished by using a masking agent sprayed into the room or area with the odor. If the odor is temporary or infrequent then the aerosol spray deodorizers will usually meet the task. If, however, the odor is from a continuous source and is strong enough or dangerous to breathe then commercial grade carbon media filters will be required.

The use of expanded carbon ( charcoal) for the reduction/removal of airborne gaseous pollutants has been around for over 100 years. These carbon media packs ( usually 1 inch to 4 inches in depth) can be very effective at removing these strong, continuous odors and the carbon can be combined with other materials to catalyze some pollutants that are not removed by just carbon alone.

Pure Air Systems, has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filtration systems, since 1985. These metal framed units incorporate the newer variable speed motors and the air flows range from a low of 50 CFM up to 2,000 CFM. PAS offers a wide range of sizes and configurations to fit any specific need. Some of the large units can hold up to 80 lbs of carbon media or applications where high concentrations of gaseous pollutants are present.

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.

Using Metal Instead of Plastic Composites

Many products that used to be fabricated from metal are now made by using an injection molding process and a wide variety of plastics to keep the cost and weight down. In many cases this option works as the strength of many of the composite plastics are very strong and will work for most applications.

In 1985 Pure Air Systems began its process of making fan powered, commercial grade, HEPA air filtration systems for both the residential and commercial markets. The cabinets used to house the filter components was mild steel that was powder coated. These rugged housings allowed for the use in both interior and exterior applications and provided a housing structure that would last 20 years or longer under heavy use.

The housings ranged in size from the small portable which is approximately 13 inches square by 21 inches long, the 600HS series which is 16 inches square by 34 inches long ( high ), The 1200 HS series which is 25 inches square by 48 inches long and the 2000HS series which is identical to the 1200HS in size. All of these units are fabricated from 16 gauge powder coated steel and are built to last.

Early in the 90’s. Pure Air Systems looked at the possibility of using strong, composite plastic materials in-lieu of metal housings but found both the cost and challenge of making a unit strong enough to hold the metal blowers, ECM motors and HEPA filter and associated prefilter material. In this case, metal was and has always been the best choice for making the high performance HEPA based air filtration systems.

The phrase ” Buy American” should be more than a slobetgan.

No matter who you talk to today, many of the older people are saying we should only buy American made products. That, today, is easier said than done. First, many individuals that order on line ( and that is the majority of people) buy products that meet their needs at the best price and seldom search for its origin of manufacture. 

Pure Air Systems, Inc. has been manufacturing its fan powered, commercial grade HEPA based air filtration systems in the US from all US made components since 1985. Today almost 95% of all the components used in the manufacture of our HEPA Shield systems are made here in the U.S. And, since its inception in 1985, PAS has always put Made in the USA stickers on our filter cabinets.

Customers that are familiar with our systems are happy to pay the higher cost for the systems knowing that the quality of our systems will provide them with great air filtration for 15 to 20 years of service, with reasonable filter changes. and minimal maintenance, Over the years many of our customers purchased less expensive, made over seas products, but eventually came back to PAS because our systems perform so much better than 95% of our competition. In fact, Pure Air Systems, Inc, is now one of only 3 companies in the word that produce this type of HEPA based air filtration system.

If You Expect To Rate As A Gentlemen Don’t Expectorate On The Floor

For the most part, human beings are fairly messy creatures…not being genetically that far apart from the animal kingdom as we know. Everyday we flake off millions of skin cells and spew out thousands of droplets of moisture every time we talk, laugh, cough or yell. This is how germs, bacteria and viruses are spread from person to person. Close contact just increases the chances of the exchange of body fluids.

Hospitals have the challenge of trying to keep their facilities as clean as possible due to the high rate of infections in hospital patients. Visitors coming into see their loved ones are one of the major players in the cause of infection, simply due to the fact that many patients are immunocompromised due to their post-operative state of health. This is why all the operating rooms are pressurized with 100% HEPA filtered air….to minimize or remove the possibility of bacteria or viruses from entering the surgery suite while the patient is under the knife.

Pure Air Systems has been making fan powered, commercial grade, HEPA filtration systems since 1985 and is considered one of the leaders in this specialized industry. These systems range in air volume from 50 CFM up to 2,000 CFM using variable speed motors for finite volume control to suit any application. PAS makes 7 different models that can be used as stand-alone units or in conjunction with a ducted HVAC system. All of the PAS models are fabricated from galvanized steel and are powder coated for a high end finish. 

Each filter unit comes complete with a prefilter, carbon media filter and true, scanned 99.99% HEPA filter. The motors are all variable speed, programmable and offer 120/240 Volt, 50/60Hz operation for locations anywhere in the world.

Gaseous Pollutants Reduction and/or Removal

Airborne pollutants come in many forms. Some we can see like smoke from manufacturing or burning leaves, or particulate in the air from a wide range of sources. But there are many pollutants that are invisible to the naked eye but may produce strong odors some of which can be deadly in large concentrations. Odors produced outside tend to dissipate quickly and unless you are next the source you may not even notice it. On the other hand, gaseous pollutants in closed spaces can be extremely dangerous unless either properly vented or contained in a controlled environment.

Many household odors such as odors from pets, food, cooking, smoking or from various crafts, can be somewhat harmful or a strong irritant if inhaled over a long period of time. These gaseous odors are not removed with standard furnace filters, as those are primarily for capturing airborne particulate, rather you will require a material that will adsorb the gaseous particles. Typically this material is comprised of activated carbon ( charcoal ) and placed in the return air stream of the HVAC system or used in a stand-alone, fan-powered unit.

Carbon is one of the most effective media for reducing and/or removing gaseous pollutants from the air. Expanded carbon has a very high surface area and can adsorb over 100 times its own weight in gaseous pollutants. This material is often contained in a mesh type bag or cannister with perforations to allow air to pass through with minimal resistance. Carbon does have some limitations in that once the carbon has adsorbed it available capacity it will then begin to release this same odor back into the air stream. Typically this material will last 2 to 4 months for most applications before it has to be replaced.

Coronavirus and HEPA Filtration

Viruses are very tiny microbial particles. They are less than .012 microns in size and are easily transmitted by air or touch. The masks that people are wearing to protect themselves from this virus. Unfortunately this is just not the case.

In order to remove viruses from the air you need some very special HEPA type filters. These are called SULPA filters. This stands for Super Ultra Low Particulate AIr or Absolute filters. These are used by the CDC and other medical clinics around the world. Most of the masks now worn by people for protection are not capable of removing any viruses and most bacteria. They are good for removing large dust particles. HEPA masks are available but very expensive and hard to breathe thru as the HEPA paper is very dense and creates a lot of air resistance. 

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985 and has a number of HEPA filter systems that are designed for residential, commercial, institutional and medical applications. Their portable unit is certainly one of the best on the market for reduction/removal of harmful airborne particulate including bacteria and some viruses. Their systems can be attached to existing HVAC units or used as stand-alone systems.

Pure Air Systems HEPA Filtration System Rescues California Home During Fires

As everyone knows, being around smoke from a forest fire is extremely difficult and dangerous as smoke inhalation can be deadly. For California this past year, the forest fires have been nothing short of horrific. Many homes were lost and smoke hung in the air for weeks in many areas of California.

Pure Air Systems, an Indiana based company, has been making fan powered, HEPA based air filtration systems since 1985. Their systems are capable of being used either in conjunction with an existing HVAC system or as stand alone units. The partial by-pass configuration of the units allow for complete filtration of the home environment while also adding the ability to introduce outside, filtered fresh air to pressurize the home.

A homeowner in the San Francisco area purchased a PAS Model 600HS HEPA Plus system to do just that. His ability to bring in outside air through the 600HS unit and pressurize his home allowed him to stay inside and almost eliminate any smoke or odor from coming into his home. In fact, many of his neighbors also came to his house to escape from the smoke that was everywhere in the SF Bay area.

The 600HS unit has three filters. A dual layer ring panel filter to capture large particles and keep the HEPA clean, a 10 lb carbon filter to remove odors and a scanned 99.99% commercial grade HEPA filter to remove sub micron particulate. Pure Air Systems also makes larger versions of this filtration system ranging from 50 CFM to 2,000 CFM. These systems have been on the market for over 34 years and are the best performing HEPA based air filtration systems on the market today.
