Designed to withstand and arrest unconfined deflagrations, confined deflagrations and both stable and unstable detonations. Required for safety in long or complex piping runs such as those encountered in vapor recovery or manifolded tank systems. These arresters are bi-directional, capable of stopping a flame or detonation approaching from either direction in a piping system. The unitized wound crimped metal arrester elements are easily removable and interchangeable, allowing a spare element to be installed during maintenance for positive protection at all times. Optional flanged or tapped fittings may be provided on the arrester housing for drains pressure taps or temperature probes if required. They have been certified for use with the following chemical vapor groups as defined in the National Electric Code (NEC Article 500).
- Series 25000 for NEC Group D,IECGroupIIA vapors
- Series 26000 for NEC Group D & C,IECGroupsIIA &IIB3 Vapors
- 150# ANSI Standard, DINPN16 Optional
- Interchangeable elements minimize "down-time"
- Low pressure drop, less susceptible to clogging
- Optional flanged or tapped fittings for drains, pressure taps or temperature probes
