Monuments

There is a lot of discussion these days about historical monuments and the issue of whether they should remain or be moved or destroyed. No matter which side you choose the fact remains that these were built for a specific purpose in their time. Many are still standing and a number are now gone.

Many corporations started out creating products that were relevant for their time in the development of our country and it’s industrial base. Over time, many of those companies have either changed completely, went out of business or merged with another larger corporation. Time changes everything.

Pure Air Systems started in 1985 by offering its’ first HEPA based, fan powered air filtration system. At the time it was slightly ahead of the curve as this type of high-end filtration system began to set the standards for high-performance in the area of reduction and/or removal of large percentages of harmful, airborne sub-micron particulate.

Over time, Pure Air Systems saw the opportunity to add larger systems with more airflow capabilities to its product line and began to expand its systems into the commercial, institutional, medical and industrial markets. The addition of the new ECM variable speed motors in 1999 added a new dimension to their product line.

The variable speed motors were magnet driven as apposed to the traditional use of wound motors thus giving PAS the ability to use digital controllers which allowed them to control the airflow in 1% increments. In addition, the motors were rated 120/240 v 50/60 Hz so they could be used anywhere in the world. This propelled the PAS line into another level which lead to the addition of 3 more products to their line.

If PAS was a monument it would probably look slightly different today, 32 years later, than the original built in 1985. Everything changes, nothing remains the same. Technology will move forward in spite of our attempts to slow it down. Time changes everything.

Make Sure Your Bakery Smells Like a Bakery

The other day I went to purchase some doughnuts at a new Bakery that opened up in an old strip mall near our house. The other tenants in the building include a bar, fix it shop and automotive repair shop at the end.

Older buildings, especially small strip mall building often had very little barrier between business compartment and odors from one business could and often did migrate into the adjacent store or even businesses two stores away.

This Bakery had that problem. Walking in to the doughnut shop one would think the aroma would be of baked goods. Not this one. It had the odor of un-burned hydrocarbons, oil and something else I could not identify. Fortunately the baked goods did not share that odor but it did make it somewhat unappetizing when I purchased the baked goods.

Pure Air Systems has been making Hepa and Carbon based, fan powered, commercial grade air filtration systems since 1985. These units can move as little as 50 CFM or as much as 2,000 CFM and can operate either attached to an existing HVAC unit or as a stand-alone system.

A 2000 CFM unit could be placed in the odor infected business and both filter out the odors and particulate as well as pressurize the environment to minimize the infiltration of the airborne contaminants. This has been done hundreds of times with the 2000HS units with exceptional results.

The problems facing the doughnut shop are duplicated in strip malls across the U.S. It is especially challenging when your store is next to a Nail Salon or Hair Salon. Odors from the chemicals used in these facilities can actually destroy your business. And trying to get the management to allow you to move to another location may not be possible or not allowed in your contract.

Home Health Care In A Box

The cost of health care continues to rise with much of the higher costs in prescription medicines and hospital treatments. We continue to see more “preventative” ideas for improving your health as you age. It is no surprise that your life style has significant impact on your short-term and long-term health. Excessive drinking, high fat food contents, smoking, lack of exercise and stress are all contributors to affecting your health.

However, one of the other areas that we continue to sweep aside but has a very significant impact on our lives is…the air we breathe.  We ingest thousands of sub-micron airborne particles every day and they come from a wide variety of areas. Grasses, pollen, ragweed, un-burned hydrocarbons, heavy metals, inorganic compounds, soot, dirt and finely ground animal particles.

Pure Air Systems has been around since 1985 making HEPA based air filtration systems for the residential, commercial, medical, institutional and industrial markets. These systems remove a very high percentage of harmful airborne particulate in any environment. Over the past 32 years we have been able to show that there is a direct correlation between living in a filtered environment and the reduction of respiratory dysfunctions, allergies and certain skin irritation issues.

Ingestion of harmful airborne particulate is also dependent upon where you live in the U.S.  The Midwest has a more stagnant air problem with a lot of particulate coming from fossil fuel (coal fired ) power plants and the industrial complex.  The coastal areas tend to get more fresh air as the ocean breezes bring in clean air from the oceans. This is especially true in State like Florida and California.

Use of air filtration in your home and office can help reduce medical costs as they help reduce the potential for health problems directly tied to the air you breathe.

Air Filtration For Your 3D Printer

For five years I have been working with 3D Printers of all types and have printed with over 20 different filaments from PLA to PETG and even Bronze. Some of these filaments when heated to over 205 degrees C to melt them for extrusion give off no noticeable odor Some, like ABS, Polycarbonate and Nylon do emit an odor. Often  a very strong odor.

It is also known that some measure of small sub-micron sized particles are released during the printing process as the extruder moves the heated filament from the nozzle to the build platform. Gases and particulate that are, perhaps,  benign in small quantities but potentially harmful in large quantities or over long terms of exposure.

Pure Air Systems along with its partner, LiteWorld LLC , have developed a plexiglas enclosure with two large access doors that will fit over most large bed 3D printers allowing for two benefits. First, the enclosure has a fan and carbon media filter to capture any odors that might be produced by the materials during the printing process. Second, the unit will significantly minimize the amount of fine airborne particles that are emitted during the printing process.

Air filtration for your 3D printer is perhaps something you don’t think about but it should be on your radar at this point in the evolution of 3D printers. Especially the FDM or FFF printers that use filament in the 1.75 mm or 2.85 mm size range.

The other reason for the use of the enclosure is the safety it provides in keeping little hands out of the moving mechanisms and from the very hot nozzle and build platform. Many schools are now requiring the use of an enclosure to fit over the printer to keep them free from any liability when used in the classroom.

Pure Air University

When evaluating a product for which you may have little knowledge it is always good to get some objective information from a reliable source. The company from which you want to purchase the product will have a lot of sales data and list the benefits and features but little about the technology used in the design and operation of the product.

The philosophy of many companies is to list features that people will recognize and not confuse them with the technical specifications.This allows for more reading space to sell the product and show the applications.

Selling air filtration systems can be challenging especially when you now have a standard that is used when rating the efficiency of the filters. The MERV ratings are used to provide the consumer with some idea of the overall effectiveness of the filters based on a percentage of removal of certain size particulate. The ratings start at 1 and go 20 with the higher numbers meaning better efficiency at removing smaller airborne particulate.

Most furnace filters are in the MERV 4 to MERV 7  ratings. These are general duty filters and they are good at taking out large particles with minimal air flow resistance. To remove a very high percent of those particles that are sub-micron in size and the most harmful you need a MERV 20 filter.

Pure Air Systems has an in-depth archive in their “Pure Air University” section that goes into depth on the technology behind air filtration, both mechanical and electronic. With this information you can better determine the type and size of air filter or filtration system required for your application or specific health issue.

HEPA Filters are rated MERV 20 and as shown in a MERV chart  and are the best mechanical filter for use in applications where sub-micron particulate needs to be removed. These units are used in medical, institutional, industrial, commercial and laboratory applications.

HEPA Filter Systems With Variable Speed Fan Drives

True, commercial grade HEPA filtration systems use a very dense HEPA paper media that requires a fair amount of energy to pull air through it using a radial blade fan. This is one reason that you have very small portable style units for the residential market as they use much smaller HEPA filters and fractional horsepower motors to keep the costs down.

These home HEPA units can usually provide up to 150 CFM of HEPA filtered air as a maximum rate and as the HEPA filter loads up it will slowly back down to the increase in static pressure.

Pure Air Systems offers a line of commercial grade HEPA filtration systems that use the variable speed ECM style motors that us magnets to turn the motor rather than copper windings. This allows for incremental speed adjustments to the motor so that the appropriate amount of horsepower is used to meet the preset CFM volume.

These motors can be programmed to speed up as the resistance across the HEPA filter increase due to dust loading thus providing a constant volume of HEPA filtered air over the life of the HEPA filter. This is critical in applications where certain air filtration exchange rates are required to maintain a clean room level class 100 or 1000 for the specific application.

The other advantage with ECM motors is their ease of modification to operate in any voltage anywhere in the world. These motors are rated 120/240 volt 50/60 Hz and with a simple wiring change the motors can be swapped to work with either voltage. This made it possible for Pure Air Systems to sell their units anywhere in the world without making any changes to their equipment’s electrical components.

The Shallows

I recently rented the movie ” The Shallows” staring Blake Lively playing a stranded surfer on an island in Mexico where she tangles with a very large shark.  The Shark won’t let her get back to shore after she inadvertently got on a small whale that the Shark had killed thinking she was taking his food.

Surprisingly the movie was good although I believe the Shark would not have been so aggressive in real life. It is always fun when movies take an idea and give it enough truth to be able to sell the unbelievable parts.

Companies often do the same thing when marketing their products. They spin the benefits and features as being the most effective and best performing of any product of its type on the market and show you a video proving their claims. Only the video, like the Shark movie, is slightly to the left of the truth. We all want to believe that what someone is telling us is both accurate and the truth. It is getting harder today to distinguish the truth from fiction.

Performance tends to be the best way to judge the merit of a concept, idea, product or even a movie. With the use of social media as the primary method of exchanging information these days, people are very quick to send out a  review of a certain product, restaurant, movie, play or people in politics. The upside is that a quality product that works well as promised will get a significant amount of positive comments by the masses. Conversely, if the product fails to live up to its performance guarantees, then a huge number of people with eviscerate the company or the product through the internet. And all the TV and newspaper ads won’t stop the bleeding.

Pure Air Systems started its company in 1985 on the premise that it would produce the highest quality, best performing products for the air filtration market. The HEPA and Carbon based, commercial grade, fan powered air filtration systems by Pure Air Systems are considered one of the best in the world today. This did not happen by accident.

Meeting the ever-changing needs of the market place is difficult. PAS has managed to do this by continuing to develop products asked for by the commercial market and consumers alike. They sell performance and reliability on a daily basis.
