Ductless Fume Cabinet. A range of six widths and an educational version.
When you want a ductless fume cabinet or hood to contain and remove hazardous fumes, vapours, gases and/or particulates in your laboratory turn to Chemcap Clearview.
Ductless Fume Cabinet and hoods
An economical solution for containing chemical fume hazards; a recirculatory Chemcap carbon filtration fume hood, may be supplied with a support bench, or placed directly onto the laboratory bench.
Once a laboratory is built it can be difficult to install new fume cupboards, the disruptive work of installation of ducting along with the capital cost of the equipment required and the planning consent needed, is sometimes prohibitively expensive and always time consuming.
Chemcap hoods are ductless with recirculatory filtration, they incorporate efficient ‘Chemcap’ carbon filters for fume removal and HEPA filters for particulates. They work by purifying air drawn through the filters and returning it thoroughly cleaned back to the room. Ductless fume cabinets provide additional safe ventilated space when you are running out of fume cupboard space.

Chemcap Cabinets conform to the requirements of all major Standards for containment and filtration:
- US Standard ASHRAE 110: 1995 12- 203 (for containment)
- British Standard BS 7989:2001 (for filter efficiency and retention capacity) ‡
- French Standard AFNOR NF X 15-211 (for filter retention capacity)
- French Standard AFNOR NFX 15-203 (for containment)
Carbon filtration
Chemcap™ filters are used in all Bigneat cabinets and provide a filtration efficiency of 99.9% for the duration of the filter life, with no deterioration in filter performance. Chemcap™ filters have been developed following years of research and are manufactured to maximise both the chemical adsorption and physical absorption characteristics of carbon to achieve this high level of filtration performance.
Bigneat is a leader in carbon filtration technology
High performance laboratory grade carbon filter media is impregnated with additives to ensure the best possible retention capacities and filtration performance. Bigneat was one of the first companies to replace potentially toxic and carcinogenic inorganic additives with environmentally friendly and biodegradable compounds whilst maintaining excellent performance.
Bigneat’s carbon media have excellent retention capacities which are amongst the best in the world. Our programme of research and development continues to improve filter performance.
- Excellent filter casing design
- Only the highest grade of carbon is used, sourced carefully and monitored for changes in its grade
- Good cabinet design ensures an even airflow through the filter
Particulate HEPA filtration
Pre-filtration eliminates particles at 5.0 microns or larger to an efficiency of 92% as defined in BS EN ISO 779.
HEPA filtration (H14 Standard) eliminates particles 0.3 microns or larger to an efficiency of 99.995%.
ULPA (U16 Standard) is available as an optional upgrade and has an efficiency of 99.999% for particle sizes of 0.1 – 0.3 microns MPPS (Most Penetrating Particle Size) as defined in EN 1822.
