Greenheck’s QEI mixed-flow fans are available with aluminum and spark resistance Type A material construction options. The expanded construction material offering combined with the QEI’s high-efficiency mixed-flow wheel makes it a great solution for challenging exhaust air applications.
The aluminum material option including an aluminum mixed flow impeller wheel, inlet cone, housing and straightening vanes is ideal for high humidity environments and corrosive environments where aluminum is a better option than coated steel. The aluminum construction also reduces the fan’s overall weight for easier handling, as well as structural concerns within a facility. Spark resistance Type A construction adds shaft seals, nonferrous shaft covers and welded tubular housing to ensure there are no spark-causing materials in the airstream, making it suitable for flammable applications such as dust, gases or vapors.
Belt-drive model QEI, direct drive model QEID and the QEID-FJ FumeJet are AMCA Licensed for Sound and Air Performance and FEI Fan Energy Index.
