This handy all-in-one unit is designed to fit in most ceiling grid systems, simplifying installation in your culture lab or other clean room. Features a 48 x 24 inch HEPA filter (47 5/8 x 23 5/8 inches actual dimension) that filters airborne particles down to .3 microns with 99.99% efficiency. The built-in three speed fan runs between 500 and 850 CFM, which can provide sufficient clean air for 10 air exchanges per hour in a 1,000 square foot laboratory (assuming an 8 foot high ceiling), and generates only 48dB of noise. The sturdy metal housing includes a 20 x 20 inch prefilter housing to extend the life of the filter (prefilter not included). This unit can be operated both horizontally and vertically, making it ideal for everything from permanent installation in culture laboratories to quick-setup spot filtration where you need it. (Note: these units are designed for general air filtration. Because of its relatively low air velocity [approximately 106 feet per minute], the MFDI4824 is not suitable for use as a laminar flow hood; it does not generate a powerful enough air flow to keep airborne particles from entering your sterile work area.) Comes fully assembled.
