    The Model 300 Roundaire Micro-Pleat mobile fume extractor is designed to protect the operator’s breathing zone from harmful airborne fumes and particulates found in many industrial settings due to welding, metal working, solvents, powder handling and chemicals. Capable of providing up to 725 CFM of air volume this system facilitates the capture of pollutants at the source before they contaminate the larger work space.

    This system is equipped with a round, cleanable and reusable Micro-Pleat Series 2 Particulate Filter that is cleaned by applying pressurized air to the filter while still in the unit’s chassis. The operator simply sprays air onto the surface of the filter media to clean and rejuvenate it, while excess dust and waste falls into the internal dust pan, allowing for simple and clean debris removal. Due to the round filter design, the unit offers greater capture area by avoiding corner dead space commonly found in non-round units. 

    The compact, light-weight Model 300 Roundaire comes with a sturdy portability handle and four industrial-grade locking casters; making moving this unit virtually effortless. Other standard features include a Variable Speed Control and Magnehelic Gage. The Variable Speed Control offers a wide gradient of power settings between 480 and 725 CFM while the Magnehelic Gage tracks filter resistance by measuring differential air pressure within the filter/fan chassis; letting the operators know when it is time to clean the filter.

    Another cleanable system is our Model 500 Industrial Fume Extractor.

    No self-cleaning components - Self-cleaning units often require a handful of parts that are required for the self-cleaning mechanism to work. These parts are often consumables as they tend to wear down and break which adds to the overall lifetime cost.
    Roundaire Benefit: With no self-cleaning components this unit will save thousands in potential lifetime costs.

    Quick and quiet cleaning - The mechanism used in self-cleaning units often stores pressurized air then rapidly releases it onto the filter creating loud, distracting noises.
    Roundaire Benefit: Cleaning the filter only requires about 3-5 minutes and the air applied by the operator is relatively quiet when compared to traditional self-cleaning units.

    Filter resistance gage - Self-cleaning units may automatically clean the filter even if it’s unnecessary. This causes wear-and-tear on the cleaning components and may burst the filter. 
    Roundaire Benefit: The magnehelic gage tracks filter resistance, allowing the operator to determine when the filter needs cleaning.

    Easy to access filter - Many self-cleaning units have the filter enclosed in a chassis which makes accessing the filter difficult and cumbersome.
    Roundaire Benefit: The exposed filter design is protected by a mesh screen which makes accessing the filter to clean it virtually effortless.
