The 500,000 THB giant purifier is expected to reduce dust particles by half. According the website of the advertiser, “The Jet Venturi Scrubber utilizes a liquid motivated ejector design to entrain contaminated gases, generally without the need for a blower…it utilizes a vertical countercurrent design for highly efficient absorption of a variety of toxic gases… and is ideally suited to the capture of small particles less than 3 microns in size. It is effective as well in the submicron range and requires little or no maintenance.”
