LAB EXHAUSTERSAlso Available Through SPR

QBMX-LE This mixed flow, in-line, belt drive lab exhauster uses a mixed flow fan. This type of design has higher efficiencies resulting in lower motor horsepower requirements and lower operating costs.

2100-LE This airfoil, in-line, belt drive lab exhauster uses an in-line centrifugal fan for commercial and industrial settings, available in both class 1 and class 2. This type of design meets higher pressures in a lab exhaust configuration.

Laboratory Exhaust System Planning“For laboratory fume hood exhausts, American Industrial Hygiene Association (AIHA) Standard Z9.5 recommends a minimum stack height of 10 ft above the adjacent roof line, an exhaust velocity Ve of 3000 fpm, and a stack height extending one stack diameter above any architectural screen; National Fire Protection Association (NFPA) Standard45specifiesaminimumstackheightof10fttoprotectrooftop workers.” ASHRAE 2011 Handbook.

To calculate the plume height such that it will circumvent building air intakes and wind re-circulating zones use the following calculation taken from the ASHRAE 2011 Handbook:

hr = 3 * b * de * (Ve / UH )

hr = plume rise b = capping factor where 1.0 is used for uncapped roof exhaustde = stack diameter ft (m)Ve = Stack exit velocity ft/min (m/s)UH = wind speed, ft/min (m/s)
