electrolytic polishing (etching), so as to avoid environmental pollution.

Explosion-proof air showers are used before personnel enter and exit explosion-proof clean areas, such as:

• Chemical plants (organic solvent workshops)

• Pharmaceutical plants (using flammable solvents such as ethanol and ether)

• Paint and coating workshops

• Workshops with high dust explosion risks (such as aluminum powder, flour, and sugar powder factories)

Design features:

• Use explosion-proof motors, explosion-proof fans, explosion-proof lighting, and explosion-proof electronic control systems

• All electronic control components are sealed to prevent arc ignition

• The control box is located in a safe area or uses a flameproof box

• There is grounding protection to prevent static electricity accumulation
