Medical air and medical oxygen flow differently through the same tube geometry, so each gas needs its own calibrated flowmeter. Don't substitute one for the other — use FM187 for medical air, FM197 for medical oxygen. For setups requiring both gases (blended therapy, ventilator support), order one of each.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhere is medical air used?\u003c\/strong\u003e\u003cbr\u003eNebulised therapy with non-oxygen-compatible medications, blended oxygen\/air respiratory support, ventilator setups requiring controlled gas mix. Most home applications use oxygen only; medical air is mostly clinical.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill my air-supply fitting match?\u003c\/strong\u003e\u003cbr\u003eSpecify your inlet (cylinder DISS, AS-2473 quick-connect, or wall-pipeline) when ordering. Gentec offers different inlets to match Australian clinical standards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does back-pressure compensation matter?\u003c\/strong\u003e\u003cbr\u003eDownstream restrictions (humidifiers, narrow tubing, masks) create back-pressure that distorts uncompensated flow readings. Compensation maintains accuracy regardless.\u003c\/p\u003e","brand":"Gentec","offers":[{"title":"Default Title","offer_id":51398761054529,"sku":"GEN-FM-187-15L","price":152.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/1550\/3937\/files\/8e1f5a03-1-16.jpg?v=1771288795","url":"https:\/\/vectrmedical.com.au\/products\/gentec-fm187-flowmeter","provider":"Vectr Medical","version":"1.0","type":"link"}
