Designed for use in glass or Perspex screens, Melaphone is specifically designed to allow sterile communication with a high degree of vision and safety. There is no thru-air flow, therefore, no transmission of germs, draughts or dust. Speech is transmitted through a transparent diaphragm which also gives protection against noxious sprays. Certified to ISO 14644-1 Class 5 for cleanroom use, Melaphone is now widely accepted within the medical industry as a low maintenance method of keeping airborne pathogens away from members of staff. Easily fitted in a 229mm dia hole in the glass or acrylic screen, the Melaphone is sealed against dust and germs by compression of the PVC closed cell gasket. The staff are protected on the public facing side by an injection moulded domed crystal clear polycarbonate slotted guard which allows speech but offers high impact resistance. The main back and front casings are made from LG Himacs acrylic resin composite which are non stain and non marking and easily cleaned with IPA wipes to maintain cleanliness.
