Apex Ductless Fume Cabinet

Ductless Fume cabinets, also referred to as portable fume cabinets, are self-contained, laboratory enclosures that remove hazardous and noxious fumes, vapours and particulate from the enclosed work area. The advantage that this design has over traditional ducted units is that the installation costs are significantly lower as no ductwork is required and there are no unsightly ducts on the outside of the building.

Ductless fume cabinets are easy to retrofit into an existing building as they will not interfere with the existing HVAC system and are thus also often a good choice from an environmental perspective as they do not remove conditioned air from the building. However, this design does have limitations that need to be considered when selecting a fume cabinet for the laboratory.

  • Intake air velocity: 0.5 – 1m/s
  • Mighting (min lux) 800
  • Power supply: 220 / 240V 50 Hz

Product Requirements

A ductless fume hood can be considered if the following criteria are met:

Limited or specific chemicals and substances, the SBT Apex range of Ductless Fume Cabinets can be supplied with a range of filter media to suit many applications for example:

  • Particulate – HEPA filters (High Efficiency Particulate Air) can filter particulate matter down to 0.3 microns to 99.99% efficiency
  • Organic Vapours – Activated Carbon Filters
  • Formaldehyde
  • Acids and Sulphur
  • Ammonia

Limited Chemical Volumes, typically it is not recommended to use a ductless fume cabinet if more than 500 mL of any chemical is to be used in the cabinet.

Limited or Short Duration, depending on the chemicals being used and the duration that the cabinet will be in operation every day will have a significant impact on the life of the filters. The expected life of the filters will usually range between 6 months and 2 years, these costs will have to be compared to the installation costs of a ducted fume cabinet as well as the additional energy costs incurred as airconditioned air is exhausted from the building.

High Temperatures, in most cases it is not recommended that ductless fume cabinets be used in applications requiring high temperatures such as acid digestion.

Our team of experts will be able to assist you in determining whether your application is suitable for a ductless fume cabinet and what filters you would require.
