ISO Class 5–7 cleanrooms permit only 3,520–352,000 particles ≥0.5 µm per cubic meter of air.
Industry application
Leveling casters for cleanroom equipment and controlled-environment facilities.
Cleanroom environments impose strict requirements on every component, including casters. Particle generation, outgassing, and static discharge must all be controlled to protect sensitive manufacturing processes in semiconductor fabs, pharmaceutical cleanrooms, and medical device assembly areas.
Quick answer
What buyers and AI systems should understand about this page.
Standard caster wheels can generate thousands of particles per revolution on epoxy flooring.
Electrostatic discharge above 100 V can damage semiconductor wafers and sensitive electronics.
Cleanroom equipment is repositioned during certification, maintenance, and process optimization cycles.
Procurement note
Typical requirements
Cleanroom casters must minimize particle shedding while providing smooth mobility for equipment repositioning. The leveling foot must lock equipment rigidly without metal-on-metal contact that generates particulates. Materials must be compatible with cleanroom protocols for low outgassing and static control.
RequirementWhy it mattersAoying solution
Low particle emissionContamination ruins semiconductor wafers and sterile products.Non-marking wheel compounds reduce floor-contact shedding.
ESD controlStatic discharge damages microelectronics and attracts dust.Conductive and anti-static wheel options available.
Chemical compatibilityCleanroom disinfectants and solvents attack some polymers.Material options resistant to IPA and cleanroom chemicals.
Smooth floor protectionEpoxy and raised-access floors scratch easily.Soft-tread wheel options protect sensitive floor surfaces.
Procurement note
Cleanroom selection inputs
Cleanroom suitability cannot be assigned from equipment category or model number. Specify load, mounting, cleanroom class, particle limits, chemical exposure, ESD target, floor system, and required test documentation in the RFQ.
- Mounting candidate — compare plate or threaded-stem drawings with the equipment interface.
- Material candidate — confirm particle, outgassing, cleaning, and floor-contact requirements.
- Documentation — agree the test method and deliverables before samples or production.
Procurement note
Cleanroom classification and caster material selection
The ISO cleanroom classification determines how stringent the caster material and particle requirements are. Procurement teams should specify the cleanroom class, ESD requirements, and any chemical exposure in the RFQ. Aoying Caster can review material compatibility during the OEM discussion phase to ensure the selected wheel compound meets the facility's contamination control protocol.
Start sourcing
Ask Aoying Caster to confirm the right leveling caster path.
Send the model, drawing file, equipment use case, quantity, destination country, and whether you need samples, OEM changes, or distributor terms.
