bimos ESD Flex stool with castors, black, seat height 450 to 650 mm, 9408E-2000

The bimos ESD Flex is a stool with a gas spring and back support for workstations in electrostatic protected areas (EPAs) where users alternate between sitting and standing. According to the ESD declaration from bimos, the series meets the requirements of DIN EN 61340-5-1 and ANSI/ESD S20.20-2021 for use in EPAs. There are three versions: Flex 1 with castors, Flex 2 with glides and Flex 3 with glides and foot ring. On all three, the seat is made of black SoftTouch PU foam and the star base of polished aluminium.

ESD properties according to the manufacturer’s specification

bimos states a typical resistance to groundable point (Rgp) of 10⁵ to 10⁷ ohms for the ESD Flex. The performance features give 10⁶ ohms as the typical value. According to the declaration, the chair can dissipate charges on persons to the conductive flooring or floor mat. As standard equipment, bimos lists conductively coated steel parts and conductive comfort upholstery, and on the Flex 1 also volume-conductive castors. The ESD declaration is a manufacturer’s declaration from bimos and not a test report from an independent test laboratory.

Castors, glides or foot ring

The Flex 1 rolls on soft, load-dependent braked safety twin castors which, according to the manufacturer, are intended for hard floors such as concrete and tiles. It adjusts from 450 to 650 mm. bimos recommends castors above all for places where you have to stay flexible and mobile.

The Flex 2 and Flex 3 stand on large-area floor glides made of abrasion-resistant plastic and range from 510 to 780 mm, which extends into the range of a standing aid. The manufacturer names glides for places where the chair has to provide support, for example for tasks requiring very high physical effort. The Flex 3 also has a chrome-plated, height-adjustable foot ring as a climbing aid, which, according to the manufacturer, provides support when greater force is applied. For raised tables and installations, the Flex 3 is the obvious choice. The Flex 2 is suitable if no foot ring is wanted.

Seat, back support and rotation

The seat surface is 360 mm wide and 380 mm deep. According to the manufacturer, the Wave surface is slip-resistant and the integrated back support supports the lumbar region. The seat can be swivelled through 360° to the left and right, which, according to the manufacturer, increases the radius of action.

Gas spring, star base and load capacity

The seat height is adjusted steplessly by a self-supporting safety gas spring. According to the manufacturer, a cover protects the gas spring from dust and dirt. The star base is a five-legged undercarriage with flat-tapering feet, made of polished aluminium and 640 mm in diameter. According to the manufacturer, the flat foot ends protect against the risk of tripping. According to the manufacturer, the load capacity is 120 kg.

Seat surface made of integral foam

SoftTouch PU foam is an integral foam, also called polyurethane or PU foam. According to the manufacturer, the surface is resistant, robust and washable and withstands pointed and sharp-edged objects. The manufacturer names integral foam for environments with oils, greases, metal chips, mild acids and alkalis or moisture. Which cleaning agents and disinfectants are suitable in an individual case, also with regard to the ESD property, should be clarified before use.

Typical applications

• Workstations in electrostatic protected areas (EPAs) in electronics manufacturing
• Assembly, testing and inspection stations in industry
• Laboratory workstations with electrostatically sensitive components
• Places with alternating sitting and standing work, at raised tables with the Flex 2 or Flex 3
• Workstations where oils, greases, metal chips or moisture occur

Frequently asked questions about the ESD Flex

Is the Flex also available without ESD?
Yes. The standard version has a black plastic star base and is not an ESD version.

Is there proof of the ESD property?
bimos issues an ESD declaration, which you can download below. It names the ESD Flex series and the typical resistance to groundable point, but no individual item numbers. If you need further proof for an ESD audit, please talk to us.

Can the seat surface be wiped clean?
According to the manufacturer, the integral foam is washable. For care, the operating instructions refer to bimos.de/cleaning.html. Please clarify with us before use which products are suitable for your application.
