DiafraCore D-3 module detail
The DiafraCore D-3 is a technical module designed to structure the breathing pattern, emphasizing mobility in the mid-torso. Its dual mechanical valve architecture combines thermoplastic polycarbonate and precision elastomer components, allowing independent resistance adjustment for both inhalation and exhalation phases. The internal system operates via small coaxial springs made from 304 stainless steel, ensuring that the tension selected on the dials remains stable through continuous use. Its ergonomics promote deep breathing centered at the diaphragmatic base while maintaining stable body posture.
- ✓ Latex-free medical-grade silicone
- ✓ Non-toxic thermoplastic polycarbonate
- ✓ Grade 304 stainless steel springs
