Ductless Fume Hood

RE-CIRCULATING FUME CUPBOARDS
AURA Re-circulating Fume Cupboards provide full fume and / or particulate containment for operator protection, exceeding safety levels required in the British Standard (BS7989) and fully compliant with COSHH regulations.
No ducting required enabling simple installation, providing an environmentally friendly solution as all exhausted air is captured by the filters resulting in zero emissions to the environment and reduced energy costs.

THE BENEFITS OF CARBON FILTRATION 
Simple installation, no connection to ductwork is necessary; 1 x 13-amp power socket required permitting flexible siting and allowing easy relocation. The re-circulating technology means no extra ventilation or heating is required, important to controlled environments like Clean Rooms or air-conditioned rooms. This means that the cupboards are exceptionally environmentally friwndly compared to ducted systems.
Carbon Filters can be used to remove a majority of chemical fumes; there are 12 types (see figure 1). Main filters can contain up to 4 blends of carbon to allow multi-purpose filtration.

HEPA FILTRATION
Powders / Particulates can be contained using HEPA ( High Efficiency Particulate Air) Filters, alternatively a combination of the two can be specified to maximize flexibility of the cabinet.
Each Filter is rated at 99.997% efficient @ 0.3microns and enables the cabinet to produce clean air to levels better than Class 100.
