It reduces the 50-60 bar cylinder pressure to a lower working pressure. This is then dosed by a small handwheel (fine needle valve) so precisely that individual CO2 bubbles can be seen and counted in the connected bubble counter. The cylinder pressure and the working pressure are indicated on pressure gauges on some pressure reducers. These displays are not strictly necessary, as - unlike with diving cylinders with compressed air - the cylinder pressure does not slowly drop, and you do not need to be warned when the cylinder is running low. Instead, the pressure remains at its maximum pressure and then drops to zero in a very short time. So, unfortunately, there is no slow decrease of the cylinder filling pressure. The working pressure would only be important if it needed to be adjusted, though this is normally not necessary. However a lot of people are happier with two pressure gauges giving them readings.\u003c\/span\u003e\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":53555713999227,"sku":"302656","price":51.59,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/files\/BasicPressureRegulator.jpg?v=1731408541"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/collections\/CO2AdvancedU-2.jpg?v=1746009304","url":"https:\/\/charterhouse-aquatics.com\/collections\/complete-co2-sets.oembed","provider":"Charterhouse Aquatics","version":"1.0","type":"link"}
