Introduction

●	Larger diameter round box filled with more activated carbon particles, allowing longer protection
●	High quality coconut shell activated carbon and high density micro and medium holes, ensuring large specific surface area and high phase-gas absorption capability
●	Activated carbon layer modified by high temperature, greatly reducing oxygen-containing groups and improving hydrophobicity (lower hydrophilia) and absorption capability
●	Activated carbon fully immersed in chemicals (metal oxide), ensuring effective chemical decomposition, catalysis and absorption
●	Circular design, high air flow speed, low breathing resistance
●	Suitable for preventing acid gases including chlorine, sulfur dioxide, hydrogen sulfide, nitrogen oxide (hydrogen sulfide prevention for escape purposes only)
