20L explosion-proof filling machine
Explosion-proof filling system for 20L drums with ATEX Zone 1 certification. Handles solvents/flammables (±0.1% accuracy). Grounding monitor & vapor recovery. 35 drums/hour.
- Brand： glzon
- Model： GZM_30L
Product Essence: Safety Engineered for Combustibles
Shanghai Guangzhi’s 20L Explosion-Proof Filler delivers ATEX/IECEx Zone 1 rated performance for acetone, ethanol, thinners (flash point <23°C). Featuring air-driven components, static-dissipative materials, and <0.1% filling accuracy, it achieves 35 drums/hour with vapor recovery >98% while maintaining oxygen concentration <5% LEL in hazardous environments.
