Erlab’s Captair Ductless Filtering Fume Hoods and Powder Weighing Stations are 100% ductless, meaning no HVAC connection to the outside is required. Some models can be placed on mobile bases to be wheeled around, or shared between laboratories. The units offer end users protection from particulate, and or liquid handlings. Units are also cleanroom compliant with HEPA at the exhaust. Customers can weigh down to six decimal places without interruption of the scale.
