SHS-CHU9937 Ultra-Self Bailer Large PVC (910mmL x 110mmW x 110mmH) 0.8L
High-Capacity Self-Bailer with Automatic Hydrocarbon Shut-Off for Spill Containment Systems
Overview
The CHU9937 Ultra-Self Bailer Large is a high-capacity drainage solution designed to safely remove clean water from spill containment areas while preventing hydrocarbons from escaping. It is ideal for larger bunds and outdoor containment systems where rainwater accumulation can significantly reduce available capacity.
This self-bailer features advanced hydrocarbon-reactive internal media that expands upon contact with oils and fuels, automatically sealing the unit to prevent environmental contamination. Its gravity-fed operation ensures continuous drainage without the need for power, making it ideal for remote or unmonitored locations.
Constructed from rigid, corrosion-resistant PVC, the unit is built to withstand harsh industrial environments. With increased flow rate and capacity compared to standard models, it provides efficient performance for higher-volume drainage applications.
