Performance & Importance of Pre-filters
A large pharmaceutical packaging and distribution company in Arizona was experiencing some failures in its prefiltration stage. The company’s pre-filters were bleeding dust downstream and reaching the recommended final resistance within just a few months time, requiring constant filter changeouts.
The company expressed its concerns to AAF International. As with all pharmaceutical packaging facilities, Indoor Air Quality (IAQ) is of the utmost importance. The company was willing to look at a new solution, but was most interested in filter efficiency, longer life, and energy efficiency.
Challenges 1 – Failure of existing pre-filters
Challenges 2 – High Total Cost of Ownership (TCO)
Challenges 3 – Improves filtration
AAF recommended that the company switch to the new MEGApleat M8 filter, the longest-lasting MERV 8 pleated panel filter in the market. The filter offered everything that the company was looking for, with a few additional benefits. In order to best illustrate the effectiveness of the MEGApleat M8 filter, AAF suggested doing a comparison study.
The company agreed and two identical air handling units (AHUs) were selected. AHU I was loaded with the current failing pre-filter product, and AHU II was loaded with AAF MEGApleat M8 filters.
It did not take long for the facility to see the advantages of the MEGApleat M8 filter. After just 90 days, the Facilities Manager (FM) did a visual inspection of the filters in each AHU. The FM could see that unlike the filters they had been using, the MEGApleat M8 filters had no shedding of dust. At the 120 day mark, the original set of filters in AHU I had already reached the final resistance, and a second set of filters had been installed. The second set of filters were loading quickly, rising to a resistance of .45″ w.g. During this same time period, the initial set of MEGApleat M8 installed in AHU II were just getting started, with only a .40″ w.g. resistance reading. Before the AAF representative could even highlight the energy savings, the FM had decided to switch all of the AHUs to MEGApleat M8 filters.
Recommended Product & Solution
Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ) is a term that refers to the air quality in your building, breathed in every day by the building’s occupants. The pollution levels in indoor air can be up to 5 times higher than outdoor levels, and people spend more than 90% of their time indoors.
Within the pharmaceutical industry, strict requirements on air purity levels are necessary because of the direct effect that airborne contamination has on the quality of the pharmaceutical products. Anything that could come into direct contact with a pharmaceutical product is a potential risk toward contamination.
Air Filtration Audit
A thorough air filter audit of your HVAC systems is the first step that AAF International takes in order to provide you with professional guidance and analysis for cost savings and risk reduction. By conducting this audit, we will be able to understand exactly how you compare to the best practices of companies that are similar to you.
