Onga PWT-SDB 0.7m Fibreglass Deep Bed Pool Filter with 1.2m Sand Bed and 4" Sight Glass

The Onga PWT-SDB-12-07-20 commercial deep bed filter combines a compact 0.7 metre vessel diameter with an extended 1.2 metre sand bed depth for applications requiring increased filtration contact time and stable commercial water treatment performance. The deeper media bed assists with improved debris retention across swimming pools, aquatic systems, and continuous-duty circulation installations.

An effective filtration area of 0.38 m² supports maximum flow rates up to approximately 15.2 m³/hr, while backwash performance reaches approximately 12.3 m³/hr during servicing and media cleaning cycles. The vessel accommodates approximately 696 kg of filtration sand media and incorporates a 2” / 50 mm valve connection together with a maximum operating pressure rating of 250 kPa.

Water movement throughout the media bed is supported by dual layers of laterals designed to maintain balanced hydraulic distribution during continuous operation. A 4” sight glass provides visual monitoring during backwash procedures, while the integrated manhole allows internal access for servicing and media inspection when maintenance is required.

The spun-woven UV resistant fibreglass tank construction provides resistance against chemically treated water, outdoor exposure, and long-term commercial operating conditions. A 50 mm / 2” drain arrangement is incorporated to simplify servicing and drainage procedures across commercial filtration installations.
