InWater Technologies provides spare parts and support for the PR Aqua drum filters, which are no longer manufactured. We stock some standard parts including screens, wheels and seals for the drum inlet, but can source most other parts as needed.
Screens
The screens for PRA drum fitlers are 18″ x 24″ (slightly smaller for 32 series) and come with the gasket glued. Available in the following sizes (microns): 11µ, 17µ, 21µ, 30µ, 40µ, 54µ, 80µ, 150µ, 200µ. If you’re not sure what size screens you have, you can check the imprint in the corner. The number of screens required depends on the model number (table below). Please specify if you have a 32 series filter.
