Q-­BOX - Cost-effective indoor explosion venting for dust explosions



The Q-Box is designed for plant components with low rigidity and large explosion venting areas. The rectangular connection complements the dimensions of standard explosion vents thus allowing it to be retrofitted to existing indoor and outdoor equipment.
