Membrane diffusers are more efficient at 2 kg to 3 kg of oxygen per kW. The Dryden Aqua diffuser at over 5 kg is therefore the most efficient fine bubble diffuser available and is ideal for retrofit applications as a simple drop in product for tanks and ponds in Aquaculture and Waste Water Treatment.\u003c\/p\u003e","brand":"Dryden","offers":[{"title":"Default Title","offer_id":47751883030842,"sku":"DA-70008-XL","price":349.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0247\/9531\/6278\/products\/dryden-air-diffusers-327168.jpg?v=1684513663","url":"https:\/\/groaqua.store\/en-nz\/products\/dryden-air-diffusers","provider":"GroAqua","version":"1.0","type":"link"}
