The Weller FT91000056 Pre-Filter Lid Complete is a robust and precisely engineered accessory designed to enhance the performance and maintenance convenience of Weller fume extraction systems. Crafted from durable, high-impact materials, this lid securely seals the pre-filter compartment, ensuring an optimized airflow path that prevents air bypass. Its rugged construction withstands frequent handling and exposure to soldering residues, securing filtration effectiveness in demanding environments.

Designed with user convenience in mind, the lid offers tool-free access via ergonomic latches, enabling quick and easy maintenance during high-throughput workflows. Technicians can perform filter swaps or inspections quickly, minimizing downtime and maintaining continuous extraction performance. Its precision fit and pressure-sealing design contribute to tight airflow control and filtration efficiency, essential for ensuring that all captured particulates pass through the intended filtration stages.

The Weller FT91000056 Pre-Filter Lid Complete integrates seamlessly with industry-standard Weller pre-filters—such as ePM1 75% class or F7 mats—and matches existing fume extraction housing units. It guards against alignment shifts or leaks and helps preserve the intended filtration order: pre-filter → main HEPA/gas filters → extraction stream. The smooth, flush surface design also simplifies cleaning and reduces areas where contaminants can accumulate.

Ideal for electronics assembly lines, soldering and rework stations, R&D laboratories, and cleanroom settings, the Weller FT91000056 Pre-Filter Lid Complete plays a vital role in maintaining extraction system integrity. By securing the initial filtration stage, it helps preserve clean airflow, extend downstream filter lifespan, and support regulatory air quality compliance. Easy maintenance, reliable sealing, and durability make this lid a key component of any professional-grade fume extraction setup.
