Entry: DanELAST Zero Leakage FRP Damper

Submitted by: Daniel Company, Upland, CA

PRODUCT DESCRIPTION
Daniel mechanical’s precision-engineered fiberglass reinforced plastic zero-leakage danelast isolation dampers feature only high corrosion resistant parts for air movement and controls. Dampers are fire retardant, corrosion resistant, and UV protected. All components are designed with replaceable parts that are easily disassembled for maintenance. Damper utilizes a specially formulated elastomer with corrosion resistance equal to and/or superior to EPDM, Hypalon, and even Viton. No circumferential blade seals are required to achieve a full shutoff of the damper thus the weakest part is eliminated resulting in greater reliability. Eliminating blade stops decreases the pressure loss across the damper. Leakage rates are tested using AMCA 500-D procedures, and the certified ratings are authorized by AMCA. Zero-leakage dampers enhance safety by providing greater isolation of process air during shutdown of exhaust system duct lines conveying hazardous air streams. When dealing with confined space entry conditions, use of these dampers may reduce safety risks caused by contaminant air leaks. Dampers require far less maintenance, are more durable, and outperform conventional butterfly dampers.
