Gas Phase Filtraion   Bry-Air, recently, setup a state-of-the-art Gas Phase Filtration laboratory at its Gurgaon plant. The lab is one of its own kind in India and in the world. The Gas Phase Filtration Laboratory (GPFL) is equipped with world class technology and systems. It is capable of testing the performance of – impregnated / non-impregnated loose granular media and impregnated / nonimpregnated air cleaning devices such as chemical filter, under one roof. The tests are conducted as per ISO/ASHRAE Standard 145.1 and BSR/ASHRAE Standard 145.2/ISO Standard 11155-2 guidelines. The core objective of the tests are to assess the performance and efficiency of loose granular sorptive media and induct sorptive media (chemical filter), in any particular application.
 
ISO/ASHRAE Standard 145.1
This standard prescribes a small-scale laboratory test method for measuring the contamination removal efficiency of loose granular sorptive media used in gas-phase air -cleaning system. The result of this test can provide information to the engineers in selection of air-cleaning equipment and the designing of air-cleaning system. The test also, allows engineers to compare the media rather than directly predicting the performance in any particular application.
 
BSR/ASHRAE Standard 145.2
This standard prescribes a full-scale laboratory test method for measuring the performance of induct sorptive media gas-phase air cleaning devices. In this context, sorptive media is defined as the active agent of the air cleaner, whether granular or sheet or pleated, that operate by adsorbing and/or chemically reacting with contaminant gases. Test is used to compare devices rather than directly predicting the performance in any particular application. The result of this test can provide information to the engineers in selection of air-cleaning equipment and the designing
