Explosion-proof vacuum cleaners can be divided into three main categories: single-person 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 user's property and personal safety:
1. The motor and carbon brush of the explosion-proof vacuum cleaner are completely enclosed inside. The pneumatic explosion-proof vacuum cleaner uses the venturi and does not require any China Vacuums Cleaners Manufacturersrunning parts and does not generate any heat.
2. The explosion-proof vacuum cleaner must be grounded to ensure that static electricity generated during the 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 and pneumatically grounded through the air supply pipe.
3. The preferred material for the explosion-proof vacuum cleaner's recycling tank is stainless steel 304 (for general industry) or stainless steel 316 (for pharmaceutical industry / clean room).
4. The explosion-proof vacuum cleaner has a HEPA/ULPA filter to capture fine dust (including toxic or annoying dust) to prevent it from returning to the workplace, and 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 static electricity can be eliminated.
