New Explosion Vent from Oseco for High Vacuum Operation

Oseco's new MV-RD explosion vent for operation in high vacuum environments.

Protecting personnel and equipment during deflagrations in high cycling/ high vacuum applications, Oseco offers the new MV-RD explosion vent. The vent provides extended in-service life, lower burst pressure (pstat) in smaller sizes, and an industry-first two-year warranty.

The MV-RD explosion vent is designed for high cycling applications, such as in dust collectors and bag houses that experience vacuum pressures up to 12 psig/ 24.4 inHg. The vent mounts on enclosures where dust explosions may occur, and will activate to safely relieve pressure in the event of a deflagration, thereby preventing a large explosion. The MV-RD can also be used on bulk storage units and in ductwork applications requiring a square explosion vent.

Oseco's newest vent features a high vacuum rating (-12 psig/24.4 inHg) to help extend the life of the vent in applications where high vacuum pressure exists. Its lower burst pressures give users the ability to reach required relief area without having to go up in vent size. Unlike other domed vents, the MV-RD can operate in temperatures up to 450°F.

The MV-RD meets the requirements of the OSHA Combustible Dust National Emphasis Program and NFPA 68. It offers industry-best performance tolerances of ± .25 psig and an operating ratio of 80%. The MV-RD is also the first product in its class to offer a two-year warranty.
