Teaching fume cupboard

chemical filtrationlaboratoryfloor-standing

Product overview
Fixed recirculating fume cupboards from Envair Technology are designed for classrooms and preparation rooms where installing ductwork is problematic (for example listed buildings). The unit recirculates air back into the laboratory via an integral fan unit and an integral carbon filter rather than exhausting to atmosphere. The carbon filter is suitable for the standard chemicals used in GCSE and A Level curriculum work.

Maintenance and compliance
Annual maintenance service is available which includes carbon filter saturation testing and replacement supply and installation of filters as required by COSHH regulations. In a preparation-room environment, carbon filter replacement will typically be more frequent due to higher usage and exposure to concentrated chemicals over time. All Envair Technology educational fume cupboards are designed in accordance with CLEAPSS Guide G9 – Fume Cupboards in Schools and are independently tested and passed by CLEAPSS.
