ESD Certified Cleanroom Garment

The company offer an electrically groundable cleanroom garment system that controls both electrostatic discharge (ESD) and particle contamination, now allowing the garment to become a part of the total environmental control process. All parts of these Class 100 cleanroom compatible garments have uniform electrical connectivity through all panels of the garment and are electrically connected from the top of the hood through the soles of the booties. When connected to a ground connection or to ground through a continuous monitor, the cord is attached from the hip, not the wrist, allowing freedom of arm movement for the wearer. Cleanroom personnel wearing the complete garment system can be grounded via the conductive bootie soles when walking on a grounded cleanroom floor without ground cord tethering. These garments were developed in response to the need to overcome poor yields and high failure rates cause by ESD in the cleanroom.

A unique option available in the garments is a patented dual-path-to-ground system that grounds both the wearer of the garment and the garment through dual continuous monitor systems. The first electrical path is from the wearer's wrist contacting the ESD knit cuff and then through an isolated ground path to a ground connection (snap) located at the side of the garment at hip level. The second electrical ground path travels from the wearer's other cuffed wrist, grounding the person and the whole garment. A dual ground cord is attached to the garment and then connected to a continuous monitor that can set off an alert if a static event occurs. The garment system can be used with all dual continuous monitors presently available.

The ESD cleanroom line is produced in the company's ISO 9001 manufacturing facility to assure reliability and performance. The garments are guaranteed to maintain their performance capabilities through the rigors of laundering and daily usage for 100 washes or 2 years. The comfortable garments come in an assortment of colors and are available in an assortment of styles including coveralls, frocks, and labcoats.
