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