Even With Great Air Filters HVAC Maintenance A Must

Most home owners have a minimal amount of knowledge about heating/cooling systems, but one thing they do know is that the unit requires an air filter. Some home owners have enough experience  to know that not changing the air filter can create problems for their air handler efficiency. Those that have severe allergies, asthma or other respiratory issues usually have significant knowledge about air filters and their efficiencies.

Over the past twenty years air filter technology and air filter materials have been significantly improved; especially those filters designed for the residential markets. Many of the newer air filters fit tighter, have more dust holding capacity and lower pressure drops or resistance. This usually means less dust in the house and less dirt and dust accumulating on the air handlers fan and cooling coil components.

As a result, many home owners often believe that general maintenance on the air handler fan and coil sections can be limited to only once every one to two years. This is certainly not true. Even with the best air filtration systems the cooling coils and air handler fan will eventually get dirty. And, keeping the cooling coils clean is important for  cooling or air conditioning efficiency.

During the year as the HVAC system shifts from heating to cooling and back again,  small amounts of moisture will develop in the duct work and small, sub-micron particles will attach to this water vapor and be deposited on the cooling coils and air handler fan blades. If this material is not removed from these surfaces it can actually cause the fan blade to get out of balance and create bearing problems or put enough of a dust coating on the cooling coils and you will reduce the efficiency of your cooling system and provide a home for mold to grow.

Most heating/cooling contractors offer a maintenance program that includes “tune ups” in both the heating and cooling seasons. If you run your systems 8 to 12 months out of the year, then you should have your HVAC system serviced at least once a year or during both seasons. In addition, you should be changing your air filter at least four times a year or once every three months. This ensures the least amount of dirt build up on the air handler components between servicing.

Pure Air Systems has been providing HEPA, Carbon and air filter media systems for the residential and commercial markets since 1985. Using a commercial grade HEPA system or one of their BioPanel air media filters in your HVAC unit will reduce the level of harmful airborne particulate while maintaining a much cleaner heating/cooling system.

Capping Off A Clean Environment For Your Favorite Beverage

The next time you pop off, twist off or pull off that cap from your favorite beverage bottle keep in mind that you are about to put your mouth around a glass surface usually without even thinking about it. Wow! Really? Yes.

When we live in an era where people are using disinfectants for their hands, wipes for any kitchen or eating surface it is interesting how much trust we have in placing that screw top bottle into our mouths without a second thought about where it has been.

To be fair, the bottling process for any beverage that is sold in the retail market is strictly controlled by state and federal regulations. Interestingly, the actual filling of the bottle with the liquid and capping process are actually done in a class 10,000 or better clean room environment.

When the term Class 10 , 100, 0r 10,000  is used, it usually means that the area, when measured for a certain sized particulate per cubic foot, needs to be at or below that required Class rating. And the rating is significant.

For example, a Class 10 rating means that when tested with the correct digital equipment the area only has 10 particles per cubic foot at a 0.3 micron level. This is clean room clean. For comparison, your home environment probably has a level exceeding 300,000 particles per cubic foot at 0.3 microns. Big difference.

Understand that most bottling plants are large factory like structures using large process equipment, conveyor belts and equipment transfer stations; for the most part a fairly dirty environment. In order to keep the actual bottling process areas (filling stations) within the required class ratings they have to use HEPA filtered air to either wash the bottles as they are being filled or maintain a class rating for the entire bottling room.

Pure Air Systems has provided a number of its commercial grade HEPA filtration systems for these bottling applications. The PAS product line includes HEPA systems rated from 300 CFM to 2000 CFM all using variable speed motors for finite HEPA air volume control.

The PAS HEPA units are small enough to be placed close to ( less than 12″) the actual filling station and wash the liquid filling process with HEPA filtered air so that no airborne contaminants will enter the bottle or cap during the filling and capping process.

So the next time you get ready to take a drink of that cold soda or brew, you’ll be comforted to know that the cap and bottle top were HEPA filter clean when they left the bottling plant.

How A&E Firms Utilize The Unique Capabilities Of PAS HEPA Filtration Systems

Architectural and Engineering firms offer engineering and design services primarily for the commercial, industrial and institutional markets.  They may design, engineer and/or specify the types of equipment, controls and materials required to bring a project to completion.

For projects that require some form of HEPA based air filtration for sanitary processes, drug manufacturing, food processing, clean room applications and medical product and health care facilities, A&E firms often work with and incorporate Pure Air Systems HEPA based air filtration systems.

The HEPA based filtration systems offered by Pure Air Systems ( PAS), offer some of the more unique capabilities and features of any HEPA based air filtration system on the market today. First, PAS makes some of the largest and most powerful stand-alone units incorporating both a three-stage filtration system along with the Genteq (GE) ECM variable speed 120/240 volt 50/60 Hz motors.

The three main units, 600HS, 1200HS and 2000HS systems are capable of moving from 100 to 600; 100 to 1200 and 100 to 2000 cfm respectively. Because they incorporate the ECM variable speed motor they can be applied to a wide variety of applications requiring HEPA filtration where specific volumes of air are required and the electrical requirements demand 240 volt motors.

The PAS units are also relatively small and light compared to their overall capabilities. The 600HS is only 97 lbs and the 1200 and 2000HS units weigh just over 200lbs. These units are configured in two different housing styles. One version is configured like an L with the inlet at the top and the discharge at the bottom side. The L versions are comprised of two separate sections that are symmetrical so the top and bottom section can be rotated for any inlet-discharge design requirement.

The S versions, or straight through versions, have the inlet and discharge openings at the ends. These horizontal units can be mounted vertically as well as horizontally and the 1200HS and 20ooHS units each have weld nuts located on the top four corners for ease of mounting.

From an Engineers point of view, the PAS units provide a unique blend of  performance, power, control and durability not found in any other HEPA filtration system today. The fact that the PAS units come standard with a scanned 99.99% at 0.3 micron HEPA filter, carbon media filter and ring panel prefilter means that these units can be applied to almost any application where true, certified HEPA filtration is required.

PAS has been making commercial grade HEPA filtration systems since 1985 and has more HEPA systems installed in commercial applications in North America, Europe and Asia than any other HEPA filtration company.
