Flat slotted lined Explosion vent, Explosion membrane – Industrial Safety Accessory

Product Description:

Burst pressure is accurately controlled by the pre- slotted lines and holes connected on the disc, and at its burst pressure, disc opens by tearing along the slots to provide a relief opening.

In production, when the air contains a certain amount of organic dust, it wil cause dust explosion, due to mechanical friction overheated, static electricity, fire, and other factors. The disk is widely used in coal, slag. medicine, chemical fertilizer, plastics, food, paint, fiber and other organic dust processing industries.

Features

Suitable for low pressure, non- backpressure, or vacuum conditions.

Designed for gas, liquid, dust service.

Maximum operating pressure up to 60% of the minimum burst pressure.
