XPert weigh boxes have inlet and outlet HEPA filters and provide a leak-tight physical barrier to protect the operator from hazardous airborne particulates and powders.

• One-piece molded, medium-density PE shell; dry powder epoxy-coated steel superstructure
• 1/4" thick laminated safety glass viewing window, removable for loading equipment, with powder-coated steel frame and neoprene gasket
• Space-saving inner and outer transfer chamber doors that pivot upward, are counterbalanced and equipped with quick-latches
• Black, chemical-resistant work surface sealed to the glove box floor
• Anti-static ionizer fan to circulate ionized air inside the box to reduce static charge during weighing
• Built-in blower with speed control capable of airflow from 13 CFM to 100 CFM
• Inlet and outlet HEPA filters, 99,99% efficient on 0,3 micron particulates

These boxes include an anti-static ionizer fan to reduce static charge and a balance vibration isolator, both useful during weighing operations. Airborne particulate cleanliness (measured under positive and negative pressures per ISO 14644-1 test method) exceeds ISO Class 5 conditions (equivalent to Class 100) and achieved ISO Class 3 conditions (equivalent to Class 1) at both minimum and maximum operational airflow volumes.
