Suitable for most types of respiratory therapy where medical air (rather than oxygen) is the prescribed gas. The S.I.S. (Specific Index System) oxygen handwheel provides safe, calibrated control across the 0-15 L\/min range.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure-compensated design\u003c\/strong\u003e — flow accuracy maintained regardless of varying supply pressures.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e0-15 L\/min outlet pressure range\u003c\/strong\u003e — covers standard respiratory therapy.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e±5% accuracy\u003c\/strong\u003e (of full scale reading) — clinical-grade precision.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eS.I.S. oxygen handwheel\u003c\/strong\u003e for safe controlled adjustment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor medical air gas only\u003c\/strong\u003e — distinct from oxygen-service equipment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eGas type: Medical air (not oxygen)\u003c\/li\u003e\n  \u003cli\u003eMaximum outlet pressure: 0-15 L\/min\u003c\/li\u003e\n  \u003cli\u003eAccuracy: ±5% of full scale\u003c\/li\u003e\n  \u003cli\u003eHandwheel: S.I.S.

The Ezi-Flow Air is for medical air supply only — pair it with a medical oxygen flowmeter (like the Gentec FM197) when both gases are required, never substitute one for the other. Common applications for medical air include nebulised therapy where mixing oxygen and air at controlled ratios is required.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhy a separate flowmeter for air vs oxygen?\u003c\/strong\u003e\u003cbr\u003eDifferent gas densities mean different float behaviour. An oxygen flowmeter used on medical air will read inaccurately — and vice versa. Always match the flowmeter to the gas.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere would I need medical air?\u003c\/strong\u003e\u003cbr\u003eNebulised therapy with non-oxygen-compatible medications, blended oxygen\/air therapy, or ventilator setups requiring controlled gas mix. Most home and basic clinical setups need oxygen only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes pressure compensation make a real difference?\u003c\/strong\u003e\u003cbr\u003eYes — wall-pipeline supply pressures can vary, and downstream restrictions (humidifiers) create back-pressure. Compensation keeps the indicated flow accurate regardless.\u003c\/p\u003e","brand":"Comweld","offers":[{"title":"Default Title","offer_id":51398761087297,"sku":"CWD-FM-EZIAIR","price":260.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/1550\/3937\/files\/986e22d0-515820.jpg?v=1771288794","url":"https:\/\/vectrmedical.com.au\/products\/comweld-ezi-flow-air-flow-meter","provider":"Vectr Medical","version":"1.0","type":"link"}
