Matala Diffuser Base w/ Dual 9" Air Discs & Riser

Award winning design! Matala offers an air diffuser assembly with hollow base that can be filled with sand or gravel. This eliminates the need for bricks and straps to get the diffuser to sink. The base is heavy duty rugged plastic with soft edges. Fill the base with small gravel and sand and purge of all air bubbles. The base comes with a friendly multi-barb that will allow connection to various sizes of air hose including 3/8", 1/2", 5/8" and 1".

• The air diffuser platform mounts diffuser firmly to bottom of pond up out of any mud.
• Hollow base is filled with sand or gravel and water to weigh it down
• Highest quality EPDM rubber membrane on the market. 
• Disc membrane is the lowest back pressure membrane diffuser on the market. 
• Handles airflow 2.1 - 8.4 cfm / 60 - 240 lpm. Recommended for 100 lpm - 200 lpm air pumps. This configuration will give a slightly smaller bubble size for a more gentle roll at the surface of pond.
• 3" riser from base to diffuser
