Add to compare

OsecoElfab’s MV-RD is a metal vent designed for high cycling applications such as dust collectors, bag houses, and bulk storage units that require a rectangular vent. It is specifically engineered to safely relieve pressure in the event of a deflagration, thereby preventing a large explosion. The MV-RD is suitable for applications that experience vacuum pressure up to 12psig/24.4 inHg and can be exposed to system pressures up to 80% of the stamped burst pressure range. Its high cycling characteristics reduce maintenance and increase the vent’s life cycle. The MV-RD is made from 316 stainless steel and features a non-fragmenting design, ensuring safety and durability. It meets NFPA 61 and NFPA 68 regulations and is available in a range of sizes from 12 x 12 to 36 x 44. The product comes with a 2-year warranty and is ideal for use in ductwork, bag houses, bulk storage, and dust collection systems.
