The EPV 6500 vent series offers a range of specialized vents designed for various applications, ensuring intrinsically safe operation. These vents are ideal for continuous flow outputs used in dilution, purging, and pressurization processes.
The EPV 6500 vent family is engineered to provide reliable venting solutions in environments requiring explosion protection. These vents are tailored for applications involving air or inert gas conversations, with options available for both low and high leakage rates to suit specific operational needs. Their robust design accommodates continuous flow, making them suitable for dilution applications, ensuring precise flow rates.
With a maximum enclosure size of 12.75 cubic meters (450 cubic feet), the vents support universal mounting in any orientation, allowing for flexible integration into existing systems. Certified for ATEX/IECEx Zone 1/21, these vents ensure safe operation in hazardous environments while meeting stringent safety standards, including up to SIL 2 according to IEC 61508. The EPV 6500 series is the preferred choice for industries requiring stringent safety measures and reliable performance in explosion-prone areas.
