CK0900-43 - Lincoln LFA 4.1 Stationary Fume Extraction Package 2HP

Industrial-Grade Source Capture Technology

The Lincoln Electric LFA 4.1 Package (CK0900-43) represents a robust solution for stationary fume extraction in industrial welding environments. Designed to mitigate the health risks associated with welding particulates and gases, this package integrates a high-efficiency 2 HP extraction fan with the versatile LFA 4.1 suction arm. The system is engineered for direct source capture, removing contaminants before they enter the welder's breathing zone or disperse into the general facility atmosphere.

At the core of this package is the 2 HP motor, wired for 230V/460V 3-phase operation. This voltage flexibility ensures compatibility with standard industrial power infrastructures. The fan is matched to the aerodynamic properties of the arm to maintain optimal face velocity at the hood, ensuring compliance with industrial hygiene standards for fume capture. The fan assembly is designed for wall mounting, typically positioned directly above or adjacent to the welding station to minimize ducting runs and maximize static pressure efficiency.

The LFA 4.1 arm offers an extended reach of approximately 4.1 meters (13.5 feet), making it suitable for large weldments or double-bay configurations. The arm features a hollow tube design with external friction joints (depending on specific revision) or internal support mechanisms that allow for smooth articulation. The 203mm (8-inch) diameter tubing minimizes airflow resistance, reducing the energy load on the fan while maximizing suction volume. The hood is equipped with a 360-degree rotatable connection and an integrated throttle valve, giving the operator precise control over airflow volume and hood orientation.

Installation of the CK0900-43 is streamlined by the inclusion of the necessary mounting brackets and connection hardware. The system is designed for durability, utilizing impact-resistant materials for the hood and heavy-gauge metal for the mounting structures. It is an essential component for facilities aiming to meet OSHA or local safety regulations regarding hexavalent chromium, manganese, and general welding fume exposure limits.
