36-Inch-Deep Ductless Fume Hood

Use a gas phase bonded carbon filter

The ductless fume hood lineup from AirClean Systems, Raleigh, NC, has been further expanded to provide lab designers with a range of options without the need for costly customization. Based on the company's 30-inch-depth design, the new 36-inch depth is available in AirClean Systems' 3-, 4-, 6-, and 8-foot wide folding-sash ductless fume hood models. These 30-inch- and 36-inch-deep polypropylene ductless fume hoods use a gas phase bonded carbon filter. This filter eliminates filter dusting and dead zones associated with many traditional granular carbon filters, according to the company. Each unit features a microprocessor-based automatic safety controller, keeping constant check on airflow and filter quality, and alerting the operator in the event of filter saturation. The ductless fume hoods feature dual-wall construction for plumbing and mounting fixtures, and a vertical sliding safety glass sash. The seamless polypropylene construction is chemically resistant and will not rust.
