What is an explosion-proof vacuum cleaner? Can you tell me more about it?

An explosion-proof vacuum cleaner refers to a vacuum cleaner that contains enough water vapor or fine dust to cause explosions or fires. Explosion-proof vacuum cleaners can be divided into 3 main categories: single-phase electric explosion-proof (EXP-series), three-phase electric explosion-proof (CD

EX series), and pneumatic explosion-proof (SS-series).

All explosion-proof vacuum cleaners must meet the following basic requirements to ensure the property and personal safety of users: 1. The motor and carbon brushes are completely enclosed inside. Pneumatic explosion-proof vacuum cleaners use venturi tubes and do not require any Moving parts, no heat is generated.

2. Explosion-proof vacuum cleaners must be grounded to ensure that static electricity generated during use of the vacuum cleaner is eliminated. The explosion-proof plug of the electric explosion-proof vacuum cleaner must have a grounding wire and must be plugged into a grounded socket. The grounding is completed pneumatically through the air supply pipe.

3. The preferred material for the recycling barrel of explosion-proof vacuum cleaners is stainless steel 304 (suitable for general industry) or stainless steel 316 (suitable for pharmaceutical industry/clean room).

4. Explosion-proof vacuum cleaners have a HEPA/ULPA filter to capture fine dust (including toxic or nasty dust) to prevent it from returning to the workplace. Some must be equipped with an activated carbon filter to absorb polluting or Toxic gases and odors.

5. Conductive straws and accessories must ensure that they can eliminate static electricity.

6. Explosion-proof vacuum cleaners need to be compulsorily certified by a well-known or recognized certification agency. The main international certifications include CSA and UL in North America, and ATEX certification in Europe.
