150 lid with D38 valve
IBC breathable cover ：
The IBC breathable cover is a special bucket cover with breathing function for 1000L IBC container barrels. It is used to balance the internal and external air pressure of the barrel, prevent collapse or bulging, and also prevent dust, leakage, and block water vapor and impurities.
Core Function - Bidirectional Breathing: Intake during discharge (to prevent negative pressure from causing deformation); Exhaust when temperature rises or liquid expands (to prevent positive pressure from causing expansion).
- Precise Protection: Built-in PTFE microporous membrane, allowing air to pass through but not liquids. It is dust-proof, water-proof, and bacteria-proof, suitable for applications in chemical, food, and pharmaceutical industries.
- Safe Sealing: Main cover sealing + independent design of the breathing valve, preventing leakage, contamination, and tampering.
