The Parker TSA source capture extraction arm systems a source extraction device that is positioned in the work zone to capture and remove dust, smoke, fumes and process emissions such as welding or cutting fume at the particulate generation source before they enter the workers breathing zone, the immediate workspace or ambient work environment. The XA extraction arm is a type of engineering control mechanism that is part of a LEV or Local Exhaust Ventilation System where it is positioned near the process or source of dust or fume generation and designed to capture, extract and evacuate any process particulate that may become entrained and suspended in the air. Capturing pollutants at the source is the most effective way to protect workers in the area and prevent dust from migrating or drifting into other areas of the workplace. Typical applications include the extraction of welding fume, oil mist machining (coolants), soldering, bulk powders and other miscellaneous dusts. The Parker TSA extraction arms are constructed with a combination of metal and plastic components. The rigid ducts and capture hood are aluminum with a black powder coated finish. The elbows are black anodized cast aluminum. The steel components including the base assembly, spring brackets, and hood brackets are steel with a black powder coated finish. All powder coated components are rated to a minimum 500-hour salt spray test. The flexible duct/hoses are constructed of UL -94V0 rated materials in order to assure quality and minimize the risk of fire. The extraction arms are flexible and allow the hood to be easily relocated near the pollutant source. Each arm is equipped with a swivel base and (2) or (3) pivot points to provide a wide range of motion and is designed to hold its position throughout the entire range of motion. The tension on each joint is adjustable allowing the user to increase or decrease the amount of force required to reposition the arm. The support system for each arm is located external to the airflow, minimizing the pressure drop through the arm and allowing for easy maintenance and adjustment as necessary. Extraction arms come equipped with a hood screen. The XA Telescopic Extraction Arm requires a wall mounting kit for either the 6- or 8-inch diameter.
