Fixed recirculating fume cupboards from TCS are designed for classrooms and prep rooms where installing ductwork is problematic eg. listed buildings. The unit recirculates air back into the laboratory via an integral fan unit and carbon filter, rather than exhausting to atmosphere. The carbon filter is suitable all standard chemicals used in GCSE and A Level curriculum work.
We can offer an annual maintenance service which includes carbon filter saturation testing and replacement supply and installation of filters as required by COSHH regulations. In a prep room environment, the carbon filter replacement would typically be more regular due to a higher level of use and exposure to concentrated chemicals over time.
All TCS educational fume cupboards are designed in accordance with CLEAPSS Guide G9 – Fume Cupboards in Schools (Revision of DfEE Building Bulletin 88) and independently tested and passed by CLEAPSS.
