Provides the maximum airflow consistent with operating efficiency, fire protection and low cost maintenance. Mounts on the end of a tank vent pipe or process vent pipe, allowing vapors to escape into the atmosphere and for air to be drawn into the tank through the stainless steel crimped metal element. They have been certified for use with the following chemical vapor mixtures as defined in NEC Article 500.
- Accurate and consistent element windings.
- Low pressure drops, less susceptible to clogging.
- Weatherhood easily removed for maintenance.
- Removable element.
