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.

House of The Rising Sun

There are some songs that seem to transcend time and this one by Eric Burton and the Animals is not exception. For almost anyone alive today hearing the first 5 cords of this song instantly remind you of what comes next. There are products and companies that also fall into this category.

Pure Air Systems, Inc. Founded in 1985, is one of those companies. PAS was one of the first companies in North America to offer true HEPA based, fan powered, air filtration systems for both residential and commercial applications. The model 600HS was the first HEPA system that was designed to attach to any forced air, ducted HVAC system using the partial by-pass concept. This allowed the use of the 600, 1200 and 2000HS series units to used in any application for any size HVAC unit with the added ability to introduced fresh, filtered outside air in small quantities to help pressurize any environment.

Today, Pure Air Systems is one of only 3 companies in the world that produce this type of commercial grade HEPA air filtration system. These units also use the variable speed drive motors and can be programmed to adjust the speed ( air flow in CFM ) to suit the application.

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.

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.

Filtration For Your 3D Printer

With over 13 years of experience in using FDM and FFF 3D style printers one learns quickly the various quirks in the operation of these printers. While they have improved dramatically since the 2011-2012 introduction of desk top printers, there are still some challenges when printing with various filament types. To be specific, ABS ( Acrylonitrile Butadiene Styrene ) has been one of the more popular materials with which to print. However, this material off-gasses when printing at 245 Degrees C and above and the odor can be quite significant. In addition, the gases produced along with some of the fine particles released during printing can become a health concern if not properly vented or isolated when printing occurs.

One of the other issues when printing with ABS is the layer separation that can take place if the object being printed cools to rapidly during the printing process. To minimize this issue you need to enclose the printer and keep the cold air drafts from falling on the printer bed. This enclosure can also also double as a mechanism to reduce the entry of the odors and particulate into the room. The use of a fan powered exhaust system attached to a vent in the enclosure along with a carbon media and HEPA filter will allow for continued use of the printer inside any room or enclosed area without compromising the environmental integrity of the room.

Pure Air Systems has been making fan powered HEPA and Carbon medial filters since 1985. These systems are designed to move from 50 CFM up to 2000 CFM with the ability to control the air volume in 1% increments. These metal framed units come in seven different configurations with the addition of a portable unit that is a prefect fit for the enclosures that would be placed over the 3D printers.

Pure Air Systems Moving to A New Location

Pure Air Systems has moved its operations from Indianapolis, IN to Danville, IN. Juist a few miles from where Pure Air Systems original location in Clayton, Indiana. This move provides PAS with more room and a more efficient assembly and parts storage area. It will also allow for development of new advancements and custom system designs.

While 2020 was a year of great challenges for most businesses, Pure Air Systems had one of its best years as more medical facilities, and institutional operations requested HEPA based air filtration systems for the reduction and removal of the Covid-19 virus. PAS is now only one of 3 companies in the world the make self-contained, fan powered, commercial grade HEPA and Carbon air filtration systems, in the world. 

In 1999 PAS introduced the variable speed motors ( ECM ) into their product line. This new addition allowed them to provide a motor that could operate at 120 or 240 volt and 50 or 60 Hz. This opened the door to exporting their systems over seas as most other countries use 220 volt/ 50 Hz electrical systems. These motors are used in all the PAS systems including the HPS Portable HEPA series. These ECM motors also allow for the use of digital controllers on the HEPA units providing infinite air volume control and programmed modulation for any application.

The PAS HEPA product line includes systems that can provide true HEPA filtered air from as low as 25 CFM to 2,000 CFM and the systems can be used in conjunction with existing HVAC units ore as stand-alone filtration systems.

Carbon Filters For Removal of Odors and Gaseous Pollutants

The removal of airborne odors and gaseous pollutants is a totally different technology than the removal of airborne particulate. To capture gaseous odors and pollutants requires some form of material or compound that can capture the gaesous molecules and hold them in place. The most commen type of material used for this type of process is carbon which is activated charcoal placed in a web-like enclosure. This material is created under high tempertures and has a very high surface area with lots of openings that can capture gaseous pollutants up to ten times its own weight. 

The term used for capturing gases and odors with carbon and other materials is the “adsorbtive process” This is different than the term “absorb” which is used with sponge-like materials. Carbon has a great affinity to capture and hold the majority of organic and inorganic gases and will hold them until the carbon becomes saturated at which time the carbon needs to bed replaced. Frequency of change is dependent upon the amount of odor producing gas and the volume of air ( in CFM ) that you are cleaning. 

Granular carbon media can be packaged in many ways. For water filtration the carbon media is placed in a porous bag or fine screen enclosure. For use in airborne processes it can be placed in a cardboard frame with fine screening material or infused in a  filter media type substrate an placed accordian style in a frame sized to fit into any opening. These carbon filters can be placed in the return air of HVAC ductwork and used in conjunction with air filters.

Pure Air Systems manufactures a complete line of fan-powered air filtration systems that can include HEPA and Carbon media filters or all Carbon media for applications where just gases and odors need to be removed. In all cases a prefiter is always placed in front of the carbon or HEPA filter fo keep the secondary filters clean.

HEPA Filters. High Efficiency Particulate Absolute

HEPA filters were developed in the early 1940’s during the creationg of the atomic bomb.The use of radioactive materials in the making of the bomb created extreme health hazards for the technicians and engineers that had to handle this type of material. Due the extremely small size of the radioactive particles ( Sub-micron in size ), readily available air filter media like furnace filters, were totally useless in reducing the levels of radioactive particulate. They needed a filter material that could absolutely remove and capture these tiny particles. 

After trying a number of materials a process using a wet laid paper type material infused with tiny pieces of glass was used to develop a very dense material that was capable of filtering out these tiny sub-micron particles. The paper like material was formed into an accordian style form with pieces of aluminum sandwiched beteween each folded layer to protect the paper-like media as it was relatively fragile and could abrade by rubbing on itself.

The filter pack was placed inside a square medtal housing and was glued in place. The outside parameter of the metal housing had a neoprene type gasket so when it was placed in a sheet metal duct it would compress the gasket to form a leak-tight seal. These filters had an initial efficiency of capturing 99.97% of all particles 0.3 microns and larger and as it got dirtier its efficiency increased. The use of this HEPA filter allowed the technicians to work in a safer environment culminating in the eventual creation of the two bombs used on Japan to end WWII.
