The Most Efficient RA LAB Fume Hood Ever.
The X-Stream Laboratory hood was engineered to be the best containing fume hood possible. Testing shows the X-Stream easily meets containment per SEFA-1 low velocity hood standard when subjected to the ASHRAE 110 test protocol with results of less than 0.05 ppm leak rate when tested at 4.0lpm at OSHA-recognized 60 fpm face velocity.
During independent testing, the X-Stream Hood was challenged well beyond the SEFA-1 standard. With a face velocity of 40 fpm and sash fully open, the X-Stream was subjected to 50fpm cross drafts, NIH protocol, and tracer gas measurements in the chest of the mannequin. In all scenarios, the protector X-Stream allowed 0.00 ppm average level of tracer gas outside the fume hood. Although your safety officer on industrial hygienist will determine the actual face velocity setting for your laboratory. the ability of the protector Hood to contain under these adverse conditions sets a new standard of safety.
Safety is foremost, but energy savings is equally impressive. Although face velocity is a factor, it's the volumetric rate (CFM) that determine the energy consumption of a hood. Operating a 6' X-Stream Hood at 60 fpm face velocity, with sash in its fully open position, requires only 690 CFM. Regardless of your desires operating face velocity, the X-Stream yields the lowest required CFM.
Energy saving translates to dollar savings. X-Stream Hood provides an excellent economic payback when compare to traditional by-pass hoods operated at 80 or 100 fpm .For example, a 6' X-Stream hood with sash fully open when operated at 60 fpm face velocity consumes a mere 690CFM as previously mentioned. Compared to a traditional by-pass hood operated at 100fpm (1250 CFM), X-Stream Hood offers significant saving, which adds up to annual dollar saving per year of $3920.
For even greater saving, RA LAB X-Stream may be factory-prepared to accommodate a variable air volume system without the need for by-pass modifications.
