Description

This sturdy 7″ Air Diffuser has a 1/4″ brass NPT fitting with a heavy base bottom plate and comes with a check valve.  The check valve stops the water from going back up the tube when the windmill flow stops.  

Normal flow for this air stone is 1.5 CFM.  This durable diffuser is made from compressed silica sand. It will handle up to about 3.5 CFM  When used for winter de-icing the air stone will give maximum water turnover for ice reduction. 

Individual check valves available upon request.
