What types of antistatic vacuum cleaners are suitable for ISO 4 and ISO 5 cleanrooms?
Antistatic vacuum cleaners suitable for ISO 4 and ISO 5 (Class 100) cleanrooms must have HEPA/ULPA filters (>99.97%@0.3μm), be made entirely of antistatic materials (antistatic hose, wheels, body), have high airtightness, and be lint-free. Equipment that meets the ISO 14644-1 standard should be preferred, and the suction power must be above 30kPa to quickly capture fine particles.
Core Requirements and Configuration:
* **Filtration System (Core):** Must be equipped with a HEPA or ULPA ultra-high efficiency filter with a filtration efficiency of 99.97% or even 99.9995%, ensuring that particles are not re-entered into the cleanroom through the motor exhaust.
* **Antistatic Design (ESD):** All components, including the body, hose, and brush head, should be made of conductive or static-dissipative materials to ensure electrostatic safety.
* **Physical Characteristics:** The equipment material should not generate dust, shed lint, be corrosion-resistant, and washable.
Airtightness: It has extremely high airtightness to prevent secondary contamination.
