FILTER TEST PORT SYSTEM
Compromised HEPA filters jeopardize patient safety by increasing the probability of a bad batch despite all other factors being ideal. Thus, HEPA filter integrity must be validated at least semi-annually to ensure the functionality.
The Aerosol Challenge is a widely used and accepted method for this test. This method requires the operator or “Certifier” to introduce an aerosolized inert oil upstream of the filter media while counting the particles which pass through downstream of the media with a calibrated Photometer.
In most cases, this process requires gaining access to the upstream airflow to the filter. This “breach” can result in a complete “terminal clean” due to contaminates entering the space. In the case of facilities, where crawl spaces have been provided to introduce the aerosol may require a second operator to introduce the aerosol, while the first operator scans the filter media.
Until now, the “certifier” must use a theoretical calculation to determine the concentration of the aerosol in the air stream. The “calculation” fails to account for such variables as distance, condensation, impaction, and loss of aerosol due to imperfections in the ductwork.
These conditions require time and effort for the performance of the test, as well as increased downtime in the production cycle of your sterile area.
The PASport System is the clear solution. Its patented design is the only CLOSED-LOOP SYSTEM on the market with both a challenge and test port as well as aerosol dispersion system for HEPA validation testing.
The 316 grade stainless steel, as well as the acrylic PASports, have smooth clean exterior surfaces suitable to be installed in most cleanrooms and are compatible with the disinfectants and cleansers used in cleanrooms today.
HEPA FILTER VALIDATION
Certifiers equipment is compatible with PASport challenge and test ports and allows them to decrease their time validating your filter by as much as 75% which should result in decreased test cost and an increase in your bottom line.
The valve system prevents unfiltered air entering the room during the attachment or disconnection process by the certifier. PASport can be installed in the ceiling next to the filter or in the wall outside room.
INCREASED TEST ACCURACY
Loss of aerosol to leaks in duct work or plenum become a non-issue. The PASport assures photometer will read the concentration of aerosol introduced into the backside of the HEPA filter.
REDUCED STAFF & DOWNTIME
Production can resume quickly. Easy connectivity to our valve system all but eliminates any particles or unfiltered air from entering the room. No breaching of the ceiling, no need for a full terminal clean post testing reduces test time and allows staff to resume work quickly.
DECREASED FINANCIAL IMPACT OF CERTIFICATION
Improvements in efficiency of testing, and reduced down time results in increased staff productivity. Return to production sooner adding to your bottom line.
