Ductless Nanoparticle Containment Enclosures

HFH Ductless Nanoparticle Containment Enclosures utilise advanced HEPA and supplementary carbon filtration technology to capture nanoparticles (less than 100nm in size). Our range of ductless nanoparticle enclosures isolate and trap chemical vapours to prevent ecological impact through release into the environment.

HEPA and Carbon filters create a safe working environment over one of the widest ranges of applications in the industry. Optional Air Velometer and mobile base stand add to overall versatility.

Ductless Nanoparticle Enclosures from HFH are self-contained and do not require venting to the outside. The cabinet is portable and may be moved with minimal downtime and without filter changes. Ductless Nanoparticle Containment Enclosures set-up, operation and filter maintenance are straightforward.

 Because filtered air is returned to the room, no demands are required of the facility HVAC capacity for make-up air improving overall energy efficiency in the facility. 

Facility ductwork, HVAC and construction costs are eliminated because filtered air is returned to the room, no demands are required of the facility HVAC capacity for make-up air. Energy-efficient ebm-papst brand centrifugal blowers promote long life and dependable performance of DNCE workstations. Internal systems are isolated from fumes, extending product life. A convenient, strategically placed front cover window shows the installed filter part number and installation date to encourage timely filter replacement in all models of ductless downflow workstations.

The electrostatic pre-filter is accessible from inside the chamber and 91% effective down to 1-3 microns and it can be replaced while unit is in operation. The main filters are easy to replace with no tools required. The filter clamps tightly against the filter gasket to prevent filter bypass and maintain filter integrity. Self testing (on selected models) assures continuous safety.
