The OK International BVX-201 Series Fume Extraction Systems are revolutionary two-arm units that combine powerful fan performance with efficient filtration, quiet operation and complete portability. They can be placed under or next to the bench-top and fitted with either two 50mm (2") diameter BVX arms or one 63mm (2.5") diameter Omniflex arm.Using the proven fan motor of the it's predecessor, the OKi BVX-100 Series, the BVX 201 Series Fume Extraction Systems, the BVX-201 Series Fume Extractions Systems add a proprietary one-stage impeller design that doubles the total free-blowing airflow.The result is a maximum free-blowing airflow of 250m3/h (150cfm), with a maximum suction force of 850 Pa (3.5"WC). This suction force provides ample capability in reserve to handle any clogging that may occur during the normal life of the filter. It is, in fact, the suction rating for this unit is one of the best in its class offered for such compact and portable systems.78% (17)
Air Filtration Machines
View of six installed HEPA-filtration machines in operation being used for asbestos abatement work; shows "reverse-side" of the air machine devices with exhaust discharge ducts. These particular machines are currently designed to function at a rate of 2,000 cubic feet per minute and remove a basic HEPA standard of at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. When an asbestos abatement project requires construction of a containment or enclosed work area, these devices are used create a negative air pressure inside the sealed enclosure, which alludes to the equipment oftentimes being refered to as "negative air machines" (NAM) or "negative pressure unit" (NPU) in some parts of the asbestos abatement and contaminant remediation industries. This type of air filtration equipment is also sometimes refered to as an "air filtration device" or "absolute filtering device" (AFD), air machine, HEPA-machine, air scrubber, or even affectionately called "hog" by certain U.S. abatement personnel.One step forward, two steps back...
Pros of new air cleaner^Wpurifier (on right): • Filter change/clean LEDs. • 'Lifetime' HEPA filter. • Adjustment knob on top instead of bottom. • Felt feet instead of hard plastic base: no longer need to put cardboard underneath it. • Actually works. Cons compared with the previous model: • Power outlet on side instead of back. • Requires you turn the unit upside down to change the filters. • Shiny pseudo-metallic plastic (which gets easily scratched when you turn the unit upside down to change the filters). • ObBlue LED. • Adjustment knob is off-high-medium-low rather than off-low-medium-high even though you're always supposed to set it to high first (hello, Fitts's law?). • Adjustment knob is labeled with stupid translucent plastic icons you can't read without squinting, instead of simple numbers 0-3. • Bigger, yet uses the same size filters and cleans the same size room. Ah, progress.
