HEPA-ULPA

ULPA Filtration Unit & Fume Scrubbing

The removal of acidic fumes presents a blanket of incoming air which passes directly overtop the samples bringing in a micro-sized contaminant; particulate matter. The addition of a ULPA filtration unit eliminates this issue. High purity air, 99.9999% free of contaminants and particles up to 0.12 µm is introduced into the system in laminar flow pattern from the top of the system. Once the front access door is closed, samples are cut off from laboratory environment completely. The air flow provided by filter assembly and external exhaust system attached to exit port is adjusted in such a way that Vulcan’s main cavity is always kept under negative pressure.
