Five properties of the Respirox valve
Flow-independent response
Opening is triggered by static pressure, not by airflow velocity.
Ultra-clear housing
Made from thermoplastic polycarbonate, keeping the scale and gasket operation clearly visible.
Guaranteed seal
Precision elastomer that seals tightly, preventing air leakage before reaching the threshold.
Non-corrosive spring
Crafted entirely from grade 304 stainless steel to resist condensation.
Compatible connection
Standard 22 mm inlet and outlet compatible with most training systems.
Threshold valve versus simple orifices
Drawbacks of simple orifice resistance
Conventional diameter reducers allow air through immediately, but disproportionately increase resistance when breathing faster. This leads to inconsistent and hard-to-measure workloads.
True threshold principle
The Respirox T-Flow valve blocks air until inspiratory force reaches the exact set target. This keeps the muscular load stable throughout the entire breathing cycle.
User experiences with the Respirox model
"You can really feel the difference when training with a threshold valve compared to adjustable orifice devices. The resistance feels identical on every inhalation."
Fernando G.
Customer
"Fits my usual mouthpiece perfectly and cleans up in two minutes. Very solid build."
