Reusable Cleanroom Coverall

What is the Reusable Cleanroom Coverall?

A reusable cleanroom coverall is a full-body polyester garment with conductive fibre grid, laundered and sterilized for repeated use. It contains particles shed by personnel in ISO 5–8 cleanrooms. It suits routine gowning.

Overview

The coverall is made from woven 100 % continuous-filament polyester with carbon or stainless steel conductive threads in a grid pattern, typically 5 mm, providing ESD dissipation. Fabric weight is 100–120 g/m2, and seams are double-stitched and sealed or bound to prevent fibre release. Closures include a zip with a cover flap and elastic or knitted cuffs, collar and ankle. Garments can be laundered in cleanroom laundries for 50–100 cycles and gamma sterilized for aseptic areas. Particle filtration efficiency of the fabric exceeds 99 % at 0.5 micrometres in standard tests. Sizes range from S to 4XL, and the hood and boots are separate or integrated depending on the gowning system.

How does it work?

Cleanroom accessories work by limiting the generation, transfer and retention of contaminants. Garments and gloves act as barriers against skin flakes, hair and fibres shed by personnel, using tightly woven low-linting fabrics with pore sizes small enough to retain particles of 0.5 micrometres or larger. Wipers absorb and remove liquids and particles using continuous-filament polyester or microfibre knit with sealed edges, so fibres do not release. Tacky mats use a pressure-sensitive adhesive layer that captures particles from shoe soles and cart wheels as they walk across. Shoe covers and boots contain floor contamination. Materials are selected for low particle shedding, low ionic and extractable residues, and compatibility with disinfectants, with cleaning and packaging done in controlled environments.

What are the key features?

• Woven continuous-filament polyester with conductive grid
• Double-stitched sealed or bound seams
• Zip with cover flap and knitted cuffs
• 50–100 laundering cycles
• Gamma sterilization option
• Sizes from S to 4XL

What are the technical specifications?

A typical reusable cleanroom coverall configuration offers fabric of 100 % polyester, continuous filament, conductive grid of Carbon thread, 5 mm spacing, fabric weight of 100–120 g/m2, filtration efficiency of > 99 % at 0.5 μm, surface resistance of 106–109 ohm and seams of Double-stitched, sealed. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Reusable Cleanroom Coverall is used in pharmaceutical production, semiconductor fabs, medical-device assembly and biotech cleanrooms. Across the wider Cleanroom Accessories class, laboratories also deploy it for pharmaceutical manufacturing, semiconductor fabs and medical-device assembly.

Which standards and certifications apply?

Relevant standards and methods include IEST-RP-CC003 (garment system considerations), IEST-RP-CC004 (evaluating wiping materials), IEST-RP-CC005 (cleanroom gloves), ISO 14644-5 (cleanroom operations), ASTM D6319 (nitrile examination gloves) and EU GMP Annex 1 (sterile manufacturing). Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Store accessories in sealed bags or cabinets in the clean area, away from moisture and sunlight, and follow first-in-first-out rotation with expiry dates. Verify supplier certificates and lot test data on receipt, including particle counts, bioburden and sterility for sterile items. Set garment laundering cycles and inspect for tears and zipper damage. Change gloves often, for example every 2 hours or when contaminated, and never reuse disposable items. Replace tacky mat sheets when soiled, and follow a documented schedule. Incorporate accessories into gowning SOPs and training, and keep records for GMP or ISO 14644 audits.

How do I select the right Reusable Cleanroom Coverall?

Choose reusable coveralls for routine ISO 6–8 use where laundering is available, and sterile versions for ISO 5–6 aseptic areas. Disposable coveralls suit low-volume or visitor use. RFQ: size range, ESD requirement, sterile option, laundering cycles and colour coding.

How does it compare with other Cleanroom Accessories variants?

Start from the room class and the contamination risk of the process. ISO 7–8 areas often use polyester garments and nitrile gloves, while ISO 5 sterile areas need sterile, double-gloved garments in low-particle fabrics. Check particle shedding, often tested to IEST-RP-CC003 and IEST-RP-CC004, extractable ions, absorbency and sterility assurance level when sterile is required. For gloves, compare thickness, length, AQL and chemical resistance. For wipers, match fibre type, edge sealing and solvent compatibility. Consider packaging, such as double bagging, and lot traceability. Compare sizes, cost per use and laundering cycles for reusable garments, and ensure items are compatible with ESD requirements in electronics.
