Features
·The constant velocity technology can avoid the risk of leaking because of low velocity or low negative pressure that caused by the voltage fluctuation or increment of HEPA (ULPA) resistance.
·The collection efficiency of ULPA for the particle , smog, microorganism between 0.1~0.2μm exceeds 99.999%.
·The blower’s full pressure is as 2 times as the initial pressure of HEPA, which effectively extends HEPA service life and reducing the operating cost.
·With the omnidistance monitoring technology, the LCD fully displays various real parameters, such as velocity, differential pressure, air quantity and HEPA (ULPA) running status, etc.
·With the innovative internal negative pressure design, any leaking airflow will be captured and environed by the negative pressure system.
·BT unique airproof design, epoxy resin coat on stainless steel frame and airproof door cover ensure no air leaking under any circumstances.
·Self-testing on ULPA/HEPA running status.
·ULPA/HEPA invalidity pre-warning and alarming system.
·ULPA/HEPA breakage alarming system.
·Double alarming system, linked with internal blower fan, consists of independent low velocity alarm and main circuit .
·Sash over-lift audio and visual alarm.
·Self-diagnosing system provides instant reaction for supply and exhaust air fan malfunction.
·Preset disinfection enhances work efficiency.
·Linkage design between sash and UV lamp protect operator from accidental ultraviolet radiation.
· In terms of human engineering, the transparent sash design with incline angle of 10°reduces the glare to maximum extent, which makes the user’s operation more convenient..
·Non-reflecting double tectorial glass specializes in explosion protection, breakage proofing and ultraviolet proofing.
·Particular seamless sealed inner surface and one piece formed, detachable stainless steel operating platform are solid, perdurable and easy for cleaning.
·Waterproof outlet and standard water and air valve fittings.
·Fluorescent lamp, installed out of the work area, makes it easy to fix and free of pollution. Illumination intensity is higher than that the NSF standard Section 49 indicates.
·The contaminated air can be exhausted into the room or out through ducts.
·BT provides all duct fittings.
