The superior design insures long life and zero maintenance. URD dampers are easy to install, easy to wire up and come with a 5 year warranty. The URD damper is constructed of heavy 24 ga galvanized steel with factory rolled stiffening beads. The nylon bearings and Thermotuff™ drive shafts insure smooth, quiet operation and provide a thermal barrier to the motor. The URD is designed to operate reliably at static pressures up to 1-1\/2 in WC. The UL listed MA-ND5 actuator is a 24 VAC 3 wire power open\/power close type rated at 18 in-lb of torque. It includes an integrated wiring terminal block and a NEMA1 rated housing. The MA-ND5 motor features bright green and red LED's which correspond to the open and closed position of the blade. The motor also includes adjustable end stops for minimum\/maximum blade position, that allows for field balancing of the full or minimum CFM flow, into a particular zone or area. The position LED's will illuminate regardless of the end stop positions.\u003c\/p\u003e","brand":"ULTRA-ZONE","offers":[{"title":"Default Title","offer_id":53407887458593,"sku":"8 URD","price":229.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0943\/1905\/1041\/files\/Ultra_Zone_10_URD_b04f7caf-c7e5-4680-aded-b0a100d42c2a.jpg?v=1787951989","url":"https:\/\/standardvmi.com\/products\/ultra-zone-8-urd-motorized-zone-damper-with-sealing-gasket-8-x-12-in-damper-24-v-ac-50-60-hz-24-ga-domestic","provider":"Standard Plumbing Supply","version":"1.0","type":"link"}
