ZGJD 6L fluorine-free foam fire extinguisher (21A 144B) has some key strengths below:

1. Environmentally Friendly: Fluorine-free fire extinguishers do not contain harmful chemicals like PFAS, which can persist in the environment and cause pollution.

2. Safer for Human Health: They eliminate exposure to potentially hazardous fluorinated compounds that may affect human health.

3. Compliant with Emerging Regulations: As more regions enforce bans on fluorinated chemicals, fluorine-free extinguishers are ahead of regulatory compliance. Soon, the EU will set fluorine-free foam as the mandatory foam in EU market

4. Biodegradable Agents: Some fluorine-free extinguishers use biodegradable agents that break down naturally over time.

5. Non-toxic Residue: After use, fluorine-free extinguishers typically leave non-toxic residue, making clean-up easier and safer.

6. Effective Fire Suppression: These extinguishers still maintain high fire-fighting efficiency without relying on fluorinated compounds.

7. Reduced Environmental Liability: Businesses and industries using fluorine-free fire extinguishers lower their risk of facing environmental fines or clean-up costs.
