An ESD chair is EPA seating that helps control charge on the operator while they work at a grounded workstation; buyers should specify resistance class intent, caster and brake rules, height range, and any cleanroom notes before comparing offers. Use it to connect seating rules with footwear and workstation carts. It is a checklist for electronics buyers – not sizing or approval for esd-chair-epa-seating-rfq.
Part 1. What Role Does an ESD Chair Play in an EPA?
An ESD chair supports personnel charge control while operators sit at grounded benches. Name the station type and shift length before comparing seating claims.
Readers searching for ESD chair usually need a project checklist, not a catalog slogan.
Part 2. Which Resistance Class and Upholstery Fields Belong in the RFQ?
State resistance class intent and upholstery expectations without inventing ohm values. Cite the program document that owns seating verification.
| RFQ field | Why it matters | Buyer note |
|---|---|---|
| Resistance class intent | Defines seating role | Cite program document |
| Height / adjustment | Fits bench ergonomics | List range |
| Casters / brakes | Controls rollaway risk | Name floor type |
| Cleanroom notes | Protects particle limits | Wipe method owner |
Part 3. How Should Height, Casters, and Brakes Be Specified?
List height range, caster type, and brake needs so chairs do not roll into uncontrolled zones.
Important: Do not buy an ESD chair from an office-furniture photo alone. Attach resistance class intent, caster rules, and footwear pairing notes. (Source: ANSI/ESD S20.20 personnel grounding practice.)
Part 4. Where Do Cleanroom or Particle Notes Fit?
If the EPA shares cleanroom rules, add particle and wipe-down expectations for seating surfaces.
Part 5. How Should Chairs Pair with Footwear and Mats?
Write entry rules so shoes, mats, and chairs share one personnel grounding story.
Part 6. Which Sanwei Routes Support Chair Program RFQs?
Sanwei routes footwear, gloves, and trolleys while ESD chair SKUs are confirmed through inquiry.
| Project signal | Sanwei route | Send with quote |
|---|---|---|
| Personnel footwear | Anti-Static Shoes | Entry sequence |
| Handling PPE | Anti-Static Gloves 3W-9517-1 | Task list |
| Chair SKU inquiry | Contact Sanwei | Class intent + caster rules |
- Anti-Static Shoes – personnel path paired with seating reviews.
- Anti-Static Gloves 3W-9517-1 – handling PPE often quoted with workstation kits.
- ESD Trolley 3W-9806101 – line-side cart route beside seating stations.

Bring the RFQ notes to the Sanwei ESD supplies range discussion, or contact Sanwei with drawings and acceptance owners.
Why not: Do not treat an unmarked office chair as an ESD chair package without resistance class intent and caster notes.
Part 7. What Are the Fit Boundaries?
This guide explains RFQ language for ESD chairs. It does not certify seating resistance or replace the site EPA owner.
FAQ
What is an ESD chair?
It is EPA seating intended to help control charge on seated operators at grounded workstations.
Which fields belong on an ESD chair RFQ?
Resistance class intent, height range, caster and brake rules, and any cleanroom notes.
Do chairs replace wrist straps?
No. Seating is one element; personnel grounding still follows the site program.
Why do casters matter?
Wrong casters can roll into uncontrolled areas or damage ESD floors.
How do shoes connect?
Write one entry sequence covering footwear and seating so operators do not skip steps.
Can Sanwei supply chairs from catalog alone?
Chair SKUs are confirmed through inquiry; footwear, gloves, and trolleys have catalog routes.
Does this page certify chair resistance?
No. Acceptance belongs to verified methods and responsible engineers.
