Efficient fan motors, low maintenance designs, and complete monitoring systems mean that Non-Ducted Fume Cupboards can cut utility costs and provide a low-cost solution for filtration in a variety of laboratories.

Which industries currently use Non-Ducted Fume Cabinets?

Non-Ducted Fume Cabinets are installed around the world in a variety of industrial and laboratory applications. Non-Ducted Fume Cabinets can be used in the life sciences, pharmaceutical manufacturing, forensics and evidence collection, industrial research, education and environmental sciences.

Can I use Non-Ducted Fume Cabinets and Ducted Fame Cabinets in the same facility?

In most laboratories, a combination of Ducted Fume Cabinets and Non-Ducted Fume Cabinets is an effective way to ensure complete filtration for all chemical applications. Non-Ducted Fume Cabinets can be incorporated to help expand the capabilities of an existing lab, while avoiding additional construction costs and ongoing HVAC and utility expenses. Non-Ducted Fume Cabinets can also be on casters to allow the unit to be moved around within a facility, providing ultimate flexibility of placement.

Do Non-Ducted Fume Cabinets run continuously?

They do not have to run continuously, but can if that is what your application requires. If continuous operation is not required, power switch controls turn off the fan and other monitoring systems. This can help cut utility costs and save on equipment wear and tear.
