Product overviewThe TopAir Downflow Powder Workstation is a standalone, ductless enclosure designed to protect operators from hazardous powders and fumes while allowing close visual and manual access to samples. Air is drawn downward through the stainless steel work surface into a multistage filtration system; cleaned air is then recirculated to the room.
Features- Welded white polypropylene structure for chemical resistance
- 304 stainless steel worktop with integrated drawer for easy cleaning
- Filtration chain: H14 HEPA stage plus activated carbon stage for fumes and odors
- Front access for quick filter replacement and maintenance
- Analog control panel with fan speed control and high-pressure (filter block) alarm
- 800 LUX, 24 W energy-efficient LED lighting
- Selectable supply voltage 110/220 V (115/230 V), 50/60 Hz, single phase
