GTI 3991 is a light-scattering linear digital aerosol photometer that subverts the traditional design with advanced technology and scientific design. After the HEPA filter is put into operation, if there are leaks or gaps due to insufficient installation, the predetermined purification effect will not be achieved, and a leak integrity test must be performed on the high-efficiency filter. Due to the low concentration of atmospheric dust upstream of the tested high-efficiency filter, it is necessary to use an aerosol generator to supplement dust generation to meet the test conditions. Use 3991 aerosol photometer to test the concentration of suspended particulate matter upstream of the high-efficiency filter and conduct a uniform-speed scanning test downstream to know the leak rate of the tested high-efficiency filter, which is convenient for the identification and quantification of leak points, and can be used as a reference for repair.

Track the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs. The OnGuard 4000 measures the overall reactivity level of air contaminants, temperature, and humidity in a controlled environment. Wall installation takes only minutes and data is accessible anytime, anywhere. The Purafil OnGuard 4000 (OG4) Atmospheric Corrosion Monitor indicates the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs. Reactivity monitoring is an accu rate and reliable method of evaluating the quality of air, characterizing the room environment, and evaluating the effectiveness of chemical filters. The OG4’s copper and silver sensors measure the rate of corrosion in real-time. An internal data logger stores the results to be accessed through the internet or directly transmit to a process con trol system. Ideal for control rooms, server rooms, motor control centers, rack rooms, or other areas where corrosion is a concern, the OG4 prompts preventive action before serious problems develop.
