The UltraTech 9938 Self Bailer Large Replacement Filter (1-Pack) is an industrial hydrocarbon filtration cartridge designed for installation within UltraTech Large Self Bailer assemblies. This engineered media insert intercepts and retains trace oils, fuels, and petroleum sheens from passing stormwater, ensuring only clean water is discharged from secondary containment structures. Regular maintenance and replacement of this cartridge prevents system fouling, sustains design flow velocities, and ensures continuous compliance with environmental discharge standards.
Key Features
-
Targeted Hydrocarbon Capture: Features specialized absorbent media that traps and solidifies trace oils and fuels while allowing uncontaminated rainwater to drain unhindered.
-
Exact OEM Fit: Precision-sized exclusively for the standard Large UltraTech Self Bailer housing to prevent bypass leaks and maintain system efficiency.
-
Optimized Flow Dynamics: Engineered to minimize flow restriction, ensuring maximum stormwater discharge rates are maintained during high-volume rain events.
-
Particulate Pre-Filtration: Acts as a secondary physical barrier to capture fine silt, sediment, and suspended solids before they can impact the mechanical valve mechanism
