Ventilated Balance Enclosure (VBE-4ft) Ventilated Balance Enclosure (VBE) Introduction Control System Package Ventilated Balance Enclosure (VBE) is designed specifically for stability and accuracy while maintaining a high level of operator protection by containing hazardous airborne powder. Using our aerodynamic design on sash and arm rest plus a sectionalized baffle, the airborne powders are well contained inside the enclosure and exhausted through a HEPA filter or direct to the lab exhaust. • RH / Temperature Sensor: 1 unit Vaisala HM120T sensor with LCD Construction The enclosure is made from powder-coated electro-galvanized sheet with polycarbonate sash and side panels. Also equipped with aerodynamic sash handle and arm rest to provide optimized airflow inside the enclosure. The design of VBE is modular in terms of exhaust and filtration system. There are three basic modules: the Base Module, the Filter Module, and the Blower Module. Key Features • Negative Pressure application provides high level of operator's protection from hazardous airborne particles • Disposal Port is equipped with O-Ring to provide a sealed Trash Bag for additional powder containment solution • Fan Speed Control: 1 unit Jumo dTRON 304 controller Filtration Package • SINGLE Filtration System: Single Bag in Bag out Filter - Efficiency: 99.995% at 0.3 micron - Classification: H14 - Media: Glass Fiber - Sealing Method: Gasket • DUAL Filtration System: Two Bag in Bag out Filter installed on top of each other - Efficiency: 99.995% at 0.3 micron - Classification: H14 - Media: Glass Fiber - Sealing Method: Knife-edge Gel sealed Warranty 1 year warranty (excluding consumables). Consumables are ballast, fluorescent, and filters. The warranty will cover all other parts including the blower, fan switch, and electrical main board. During the period of warranty, any repair, modification, testing and commissioning performed by any unauthorized party other than the Esco Service Team, shall void the warranty of the unit. • Modular Design using VBE modules the unit can be fully customized • Filtration System VBE can be equipped with a Filter Module or a Portable Filter Module for added air flow control Blower Module can be added.

EXHAUST MODULE VBE have 3 options for Exhausting Filtered Air such as DUCTED, DUCTLES, PORTABLE FILTER MODULE Filter Module be configured as Dual or Single Filter. Each module Section quantity may vary form 1 - 3 Depending on the Width of the Ensclosure. Additional Carbon filter may be supplied for Odor Control Single Filtration Module Dual Filtration Module ENCLOSURE MODULE VBE Enclosure covers a wide range weighing and powder handling options and requirments. We have the SMALL, MEDIUM, LARGE models. Small Models, is perfet for small spaces, add portable filter options and the enduser will save...
