Enclosure protection vent
EPV-*-SA-*
Features
• Top or side mount configurations
• Seamless cap
• Friction free valve assembly
• Spark arresting exhaust
• Can only be purchased in conjunction with corresponding
Purge system or as a replacement
Function
The EPV (enclosure protection vents) are self-seating, gravity
controlled, low pressure relief valve designed to ventilate
excessive enclosure pressures created by the Rapid
Exchange
control devices.
Each vent features a seamless cap, a spark arresting (SA)
style exhaust element, a friction-free valve assembly, a base,
and a mounting hub. The mounting hub, along with associated
pipe fittings, permits direct mounting through a round cutout
on the top or side of a protected enclosure.
This device functions only in conjunction with Pepperl+Fuchs
Bebco EPS® purge systems, to reduce the hazardous
(classified) area rating within protected enclosure(s), in
accordance with the NEC - NFPA 70, Article 500, NFPA 496,
and ISA 12.4.
