Bigneat is firmly established as a world-class manufacturer and leading global provider of ductless fume cabinets, powder weighing satety cabinets. Clean air, hazard containment and safety systems to scientific laboratories and industry.

 

Applications for Bigneat products embrace operator and process/sample protection during laboratory procedures, batch and on-line production processes.

 

The core technologies of these and other cabinets requiring chemical fume and vapour removal is Chemcap™ carbon filtration, first used in ductless fume cabinets, but now used in all types of custom built enclosures and cleanrooms along with HEPA filtration for particulate removal.

Cabinet Filtration Technology

Carbon filtration for chemical fumes and vapours

Highly efficient Chemcap filters eliminate toxic substances and compounds within the recommended occupational exposure limit for pollutant gases having molecular weight equal to or greater than 30. Efficiency is 99.9% for the duration of the filter life and with no deterioration in filter performance.

 

Particulate filtration for aerosols and particulates

Pre-filters fulfil the need to arrest larger particles and are fitter to all Chemcap Clearview cabinets, HEPA filtration is fitted as an option when aerosols and small particles require removal. This can be upgraded to ULPA filtration when nanoparticle removal is required.

Key Development

New Chemcap Clearview cabinet utilise filtration more effectively with an overall retention improvement of 20%

Improvements in the flow patterns in the design of Chemcap Clearview cabinets ensure that more of the carbon within the filtration bed is utilised and that retention capacity is maximised.

Choosing your optimised Chemcap filtration

Bignet offers a multi-purpose (universal) filter which should be selected when a fume cabinet is to be used for a variety of different procedures and handlings.

 

For best performance Bigneat’s chemist recommends choosing an optimised filter which will give the best retention and a long filter life.

Fume Extraction and LEV Dust

Flexible or jointed-arm local extraction. The effective way to eliminate airborne hazards.

Cleantec for Fume extraction and LEV dust is adaptable and may be used as a free standing system, on a mobile or static workbench, with a single flexible or jointed arm, installed under-bench with multiple arms or connected direct into process equipment. With a manual fan speed control it is ideal for either light duties in laboratories, education, or for heavier duties requiring the full power of the fan.

 

Cleantec LEV is designed to solve your fume, dust and odour problems at the press of a button. Efficient filtration within a powerful extraction system removes hazardous material from your process direct from where the extraction is required.
