This "Demo Machines line-up" catalog presents three distinct industrial equipment types for various applications. The "Horizontal type" is a versatile unit designed for both outdoor and indoor trials, offering multi-purpose utility. The "PJ-2" is engineered for indoor circulation, likely managing air or other substances to maintain specific environmental conditions. Lastly, the "Vertical type" serves as a local suction solution exclusively for indoor use, featuring an upright configuration with a U-shaped duct for effective localized extraction of airborne elements directly at their source. These demo machines collectively provide flexible options for testing, environmental control, and localized air management in industrial settings.
