What ISO cleanroom classes are Jesterlift equipment compatible with?

Jesterlift cleanroom material handling equipment is certified to ISO 14644 Class 7 as standard and is compatible with ISO Class 5 through Class 8 environments. Class 5 and Class 6 deployments are available with enhanced electropolish specification and additional particle generation testing on request.

What makes cleanroom-rated equipment different from standard industrial equipment?

Cleanroom-rated material handling equipment differs from standard industrial equipment in five key areas: particle generation (electropolished stainless vs painted carbon steel), surface geometry (no crevices or open weaves that trap contamination), hydraulic design (fully enclosed systems vs open reservoirs), static management (anti-static materials and grounding paths), and documentation (full ISO 14644 compliance pack vs none).

Does Jesterlift supply documentation for cleanroom qualification?

Yes. Every Jesterlift cleanroom equipment order ships with a complete qualification documentation package: ISO 14644-compliant design record, mill certificates (304L or 316L), electropolish surface roughness report (Ra ≤0.5 µm certified), IQ/OQ template, FAT/SAT protocol and change control log — all packed in the crate with the machine.

The contamination risk standard equipment carries

Standard industrial equipment is a contamination source. By design.

Standard industrial material handling equipment is engineered for warehouses, loading docks and manufacturing floors where contamination control is not a design requirement. When that equipment enters a cleanroom, it brings every contamination source along: particle-shedding paint, open hydraulic reservoirs, carbon-steel surfaces that corrode and shed, open-weave components that trap and release debris, and crevice geometries that defeat any cleaning protocol.

The result is not a matter of degree — it is a classification failure. Introducing a standard pallet truck into an ISO Class 7 pharmaceutical or medical device cleanroom creates an uncontrolled particle source that invalidates the environmental monitoring programme the facility has invested months establishing.

Jesterlift cleanroom material handling equipment is engineered from first principles for classified environments. The contamination sources present in standard equipment are eliminated, not mitigated — through 304L and 316L stainless construction, electropolished surfaces, enclosed hydraulics, anti-static design and the complete removal of paints, open fabrics and crevice geometries from the product.

01 · What cleanroom-rated equipment means

Five design decisions that separate cleanroom equipment from the rest.

Cleanroom certification is not a label applied to a standard product. It is the outcome of specific engineering decisions made at every level of the design — materials, geometry, actuation, surface finish and electrostatic management.

Controlled Particle Generation

Electropolished 304L and 316L stainless surfaces generate no paint particles, no rust particles and no fiber contamination. ISO 14644 cleanroom qualification testing verifies particle counts at every class level — Jesterlift units pass Class 7 as standard, with Class 5 and 6 available on request.

No Crevices, No Traps

Standard equipment is assembled with crevice geometries — gaps between components, open fastener threads, recessed bolt heads — that trap contamination and resist cleaning. Jesterlift cleanroom units use crevice-free weld geometry, flush fasteners and continuous-weld construction to eliminate every trap site.

Electropolish to Ra ≤0.5 µm

Mechanical polishing leaves a directional surface pattern with micro-peaks that anchor contamination. Electropolishing removes those peaks electrolytically, producing a mathematically smoother, isotropic surface that is certifiably cleaner, more corrosion-resistant and easier to sanitise. Ra values are measured and reported on every unit.

Anti-Static Construction

Static charge accumulation on equipment surfaces attracts and holds sub-micron particles, defeating even the most thorough cleaning protocol. Jesterlift cleanroom units are built with anti-static materials and conductive grounding paths throughout, preventing static-driven particle adhesion in the lowest-particle-count environments.

Fully Enclosed Hydraulics

Conventional hydraulic systems use open or semi-open reservoirs that allow hydraulic fluid to contact classified air. Jesterlift cleanroom units use fully enclosed hydraulic systems with sealed reservoirs and positive-seal fittings — eliminating aerosol generation and fluid contamination risk across all normal operating conditions.

02 · ISO class compatibility

Equipment for every cleanroom classification.

ISO 14644 defines cleanroom classes by airborne particle concentration. Jesterlift material handling equipment is validated for the classes where material handling operations most commonly occur — from ISO Class 8 secondary packaging through ISO Class 5 aseptic filling.

05 · FAQ

Frequently asked questions.

Jesterlift cleanroom material handling equipment is certified to ISO 14644 Class 7 as standard, with compatibility across ISO Class 5 through Class 8 environments. ISO Class 7 and Class 8 deployments use standard 304L or 316L specification. ISO Class 5 and Class 6 environments are supported with enhanced electropolish specification (Ra ≤0.25 µm) and additional particle generation testing — available on request when ordering.
Cleanroom-rated material handling equipment differs from standard industrial equipment across five critical design dimensions. First, particle generation: electropolished stainless steel generates no paint particles, rust or fiber contamination, unlike painted carbon steel. Second, surface geometry: crevice-free weld construction eliminates contamination traps that standard equipment retains. Third, hydraulic design: fully enclosed systems prevent hydraulic fluid aerosolisation. Fourth, static management: anti-static materials and conductive grounding paths prevent particle adhesion from electrostatic charge. Fifth, documentation: ISO 14644 compliance documentation is supplied as standard; standard industrial equipment carries none.
Yes. Every Jesterlift cleanroom equipment order ships with a complete qualification documentation package: ISO 14644-compliant design record, 304L or 316L mill certificate (with heat number and material traceability), electropolish surface roughness report (Ra ≤0.5 µm measured and certified, calibration record included), pre-filled IQ/OQ template, FAT/SAT protocol and dated change control log. All documents arrive in the crate with the machine — not requested through a portal three weeks after the purchase order closes.
