Powered dilution exhaust fan. Unit’s axial design creates high dilution rates while maintaining high plume. Power Plume design eliminates the need for mixing box and is superior to any adjustable nozzle design. Unit can be mounted to curbs, stacked or directly paired to a primary laboratory exhaust fan. Typical applications include any laboratory project where the energy savings is required without compromising safety, and projects where the wind study findings show the need for the highest available plume.
