Same as the BV660H-D but 930mm wide contains a larger filter two fans. Also single speed.The BenchVent BV930H-D is a large ducted hood mounted local extraction cabinet designed specifically for laboratories. It is commonly used in dental & medical labs pharmaceutical laboratories research & development and school science laboratories.This unit exhausts air through a flexi-duct externally to the atmosphere. Although it's a ducted fume extractor you don't need to have a special vent to use the BV930H-D. Its flexi-ducts can be fitted to a normal domestic vent or placed on a partially opened window. (We would recommend either one hole per duct or if combining into on outlet the outlet should be 150mm diameter)The BV930H-D also provides operators with a safe workstation as handling of all the potential harmful chemicals is done within the hood enclosure in front of the the intake filter area. For artwork applications the enclosure can accommodate a standard A1 drawing boards which will fit at an angle so the unit captures the over-spray efficiently keeping the surrounding working area clean.The BV930H-D fume cabinet is designed for immediate operator protection . If outside venting isn't possible BenchVent also offers re-circulatory fume cabinets such as the BV660H-C and BV930H-C.
