Spirafirm EX-3 Calibrated Expiratory Device

Expiratory resistance instrument with magnetic-mechanical system
The Spirafirm EX-3 generates continuous positive resistance during the exhalation phase, promoting controlled work of the abdominal and internal thoracic muscles. Its fixed-chamber mechanical design ensures a constant airflow without sudden backpressure spikes. The internal system relies on a balanced 304 grade stainless steel plunger that responds immediately to the outgoing flow. The laser-etched scale on the outer body allows tracking training progress without depending on batteries or complex external calibrations.

User experiences

★★★★★

"The piston glides very smoothly and does not jam at the end of the breath. The clear body gives peace of mind to see that everything is clean inside."

Guillermo T. Customer
★★★★★

"The adjustment locks securely and does not slip on its own. It is a solid device and easy to wash after exercising."

Nuria L. Customer
This product is a mechanical expiratory resistance instrument for general physical exercise. It is not a medical physical therapy device, nor is it intended to clear pathological secretions or treat bronchial conditions.

Frequently asked questions

How does it differ from an inspiratory trainer? +

The Spirafirm EX-3 provides resistance exclusively when blowing out, allowing free inhalation without load.

Does it make disturbing noises during exhalation? +

The passage of air creates a soft, steady sound characteristic of restrictive flow, with no metallic clicking.

How is it disassembled for periodic cleaning? +

The top cap unscrews by hand, releasing the plunger and spring for thorough washing with warm water.

What payment options can I choose when ordering? +

We accept cash on delivery upon arrival or bank transfer prior to dispatch.
