FA-I-FC

Flame Arrester Unit for installation in devices

Function and Description

The PROTEGO® FA-I -FC flame arrester units are components installed on or within equipment (e.g. blowers) and have to be tested and approved with this equipment for the respective operating conditions of use. It consists of a FLAMEFILTER® cage (2) filled with FLAMEFILTER® (1). The FLAMEFILTER® cages are sized so that they can be installed between flange connections. The component provides equipment manufacturers protection against deflagrations, volume deflagrations or protection of engines. Each PROTEGO® flame arrester unit is selected from a modular system that provides each manufacturer the option of using optimized, adapted, and cost-effective protection. Our expert technical staff will assist you with the proper selection of the devices as well as execution of type testing.

The PROTEGO® FA-I-FC flame arrester unit consists of two FLAMEFILTER® installed within the FLAMEFILTER® cage. The FLAMEFILTER® diameter and gap size depend on the intended use. PROTEGO® FA-I-FC components can be arranged for all explosion groups and special gases such as ethylene oxide.
