High durability






| Category | EPL Air Diffuser | Composite Rubber |
|---|---|---|
| Material | Silicon and polyurethane | Composite Rubber |
| Characteristics | Excellent efficiency of oxygen delivery | Easy hardening due to containing the plastic component |
| Constant air discharge by the air guide design | A lot of stretching | |
| Excellent strength due to the silicon polyurethane material | Slot clogging due to weak resilience | |
| Long-term use by excellent elasticity and resilience | Low resistance against chemical and oil | |
| Excellent resistance against chemical and oil | Decrease performance as the sealing ability deteriorates over time | |
| No hardening due to the property of the material | Weakness against ultraviolet rays |
