The patented* Protector XStream Laboratory Hood was engineered to be the best containing fume hood. Testing shows the Protector XStream easily meets containment per SEFA-1† low velocity hood standards when subjected to the ASHRAE 110† test protocol with results of less than 0.05 ppm leak rate when tested at 4.0 lpm at OSHA-recognized 60 fpm face velocity.
During independent testing**, the Protector XStream Hood was challenged well beyond the SEFA-1† standards. With a face velocity of 40 fpm and sash fully open, the Protector XStream was subjected to 50 fpm cross drafts, NIH† protocol, and tracer gas measurements in the chest of the mannequin. In all scenarios, the Protector XStream allowed 0.00 ppm average level of tracer gas outside the fume hood. Download the independent test results now. Although your safety officer or 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 determines the energy consumption of a fume hood. Operating a 6' Protector XStream Hood at 60 fpm face velocity, with the sash in its fully open position, requires only 690 CFM. Regardless of your desired operating face velocity, the Protector XStream yields the lowest required CFM.
Energy savings translates to dollar savings. The Protector XStream Hood provides an excellent economic payback when compared to traditional by-pass hoods operated at 80 or 100 fpm. For example, a 6' Protector XStream Hood with sash fully open when operated at 60 fpm face velocity consumes a mere 690 CFM as previously mentioned. Compared to a traditional by-pass hood operated at 100 fpm (1250 CFM), the Protector XStream Hood offers significant savings, which adds up to annual dollar savings per year of $3920.††
For even greater savings, the Protector XStream may be factory-prepared to accommodate a variable air volume system without the need for by-pass modifications. Learn more. Download the brochure now.
