Flow Sciences FS4500 Stacked HEPA 12404 Dual-Stage Filtration Accessory

The Flow Sciences FS4500 Stacked HEPA 12404 is a powerful, space-efficient dual-stage filtration system designed to protect both laboratory personnel and sensitive processes. Engineered for use with balance enclosures and other containment systems, it combines high-efficiency particulate capture with odor reduction in one compact unit. By safely recirculating filtered air back into the workspace, the FS4500 provides a compliant, cost-effective solution for labs that lack external exhaust systems while maintaining a clean, controlled environment.

At HiTechTrader, we make advanced containment systems like the FS4500 accessible to laboratories of all sizes by offering thoroughly tested refurbished units. This model integrates a HEPA filter for particulate control with an activated carbon stage for odor abatement, delivering robust protection in pharmaceutical labs, weighing stations, and toxic powder handling environments. Compact yet durable, the FS4500 is built for seamless integration with Flow Sciences enclosures and ensures continuous safe operation without requiring costly facility modifications. It's a reliable way to keep your lab compliant, your personnel safe, and your weighing operations accurate.
