TECHNICAL SPECIFICATIONS
F&P ESON 2 EXHAUST FLOW
The F&P Eson 2 Nasal Mask has a unique Diffuser System that is designed to diffuse air which
is expelled from the mask. This reduces draft. The Diffuser does not significantly change the
amount of air flowing from the mask; therefore, the mask can be used with or without the
Diffuser.
