GBK Containment Systems

Flexible Protection for Filter Change-Out

GBK containment systems provide easy-to-use, enhanced containment during filter change-out operations. The systems combine specially designed filter housings and glove bags that seal together, shielding the operator and the surrounding environment from undesirable exposure to harmful liquids and particulates (eg. actives, catalysts). The operator is easily able to introduce replacement filter cartridges into the glove bag via a zippered feed-in sleeve, and then remove the used/spent filter cartridges via a feed-out sleeve using the glove bag’s sensitive nitrile gloves.

The GBK containment system is based upon well-established Pall housing ranges, which have been modified to take the specially-designed glove bags. GBK glove bags have been designed by experts with over twenty years' experience of containment practices in Active Pharmaceutical Ingredient (API) facilities to provide the optimum combination of efficacy, convenience and value. GBK glove bags are available with sealed sleeves to provide solutions for more critical applications, or with feed-in sleeves to provide solutions where greater operational flexibility is required. 

Features and Benefits

 

• Easy to install and to implement into existing process
• Provide flexible economical containment for filter change-out
• Operator-friendly handling/manipulation (typically, a trained operator can perform a complete filter cartridge change-out in 90 to 120 seconds)
• Enhanced containment - independent tests have demonstrated that GBK systems have good ergonomics and are capable of containing a placebo material to 1μg/m³
• PATK series housings provide a compact and robust housing design for Code 7 cartridges and are ideal for API applications
• Two standard glove bag designs are available to suit most requirements
• GBK nitrile gloves have a cuff and elastic ring sealing mechanism with the glove bags and may be easily replaced by alternative site standards if required
• GBK glove bags have a built-in HEPA filter to prevent condensation
• Pall can provide technical support including operator training if required

GBK systems based on other housings and glove bag designs are possible - please contact Pall for details.
