TriMAT System
High level of operator protection, fully compliant with EN 12469:2000.
Product features
The TriMAT system can be fitted to the full range of CAS microbiological safety cabinets and provides as standard:
Design benefits for containment laboratory designers
The Advisory Committee on Dangerous Pathogens (ACDP) guidance on the design of containment laboratories stipulates that facilities should be maintained at a constant negative pressure (typically -30 to -50 Pa) to ensure safe containment. The use of the constant exhaust TriMAT system greatly simplifies containment laboratory air handling design by providing a fixed exhaust volume irrespective of whether the cabinet if ON, OFF, or undergoing fumigation.
Containment laboratories are normally designed to provide at least 20 air changes per hour. The TriMAT bypass module can allow significant additional room extract volume through the cabinet exhaust duct. This feature can greatly simplify overall air handling design and cost by negating the need for dedicated additional room extracts. TriMAT cabinets can also be manifolded into a central exhaust system allowing for multi-cabinet installations, further reducing design and installation complexity and cost of ownership.

Operational benefits for containment laboratory staff
Normal cabinet operations are completely unaffected by the provision of a TriMAT exhaust module on the microbiological safety cabinet. However, should the main extract fan fail during cabinet operations, the user is immediately alerted to the problem via an audible and visual alarm. The cabinet will immediately revert to recirculation operation returning exhaust air to the laboratory.
This is allowable as the TriMAT module is fitted as standard with a double H14 HEPA cabinet exhaust filter. The user can safely complete cabinet operations under full containment and then shut the cabinet down. Once the cabinet has been switched off, it cannot be restarted until the main exhaust system is healthy.
