Flame Arrester
for vacuum pumps, compressors and blowers

Función y Descripción

PROTEGO® FA-I -V and FA-I -P flame arresters are specifically designed for vacuum pumps, blowers, and compressors. The high flow velocity in the small gaps of these machines can lead to undesirable ignitions within the housing. One of the safest measures against explosion propagation are flame arrester units that are installed on the vacuum and pressure side of the equipment. PROTEGO® FA-I-V devices for the vacuum side and PROTEGO® FA-I-P devices for the pressure side provide a unique modular design that gives every manufacturer of vacuum pumps or comparable devices the option of using optimized and adapted flame arresters. Our expert technical staff will assist you with the proper selection of the devices as well as execution of type testing.

PROTEGO® FA-I-V and FA-I-P devices are symmetrical in design. The arrester essentially consists of two housing parts (1) and the PROTEGO® flame arrester unit (2) in the center. The PROTEGO® flame arrester unit is modular and consists of several FLAMEFILTER® (3) and spacers firmly held in a FLAMEFILTER® cage. The number of FLAMEFILTER® and their gap size depends on the arrester´s conditions of use. PROTEGO® FA-I-V and FA-I-P flame arresters are available for explosion groups IIA to IIC (NEC groups D to B) and special gases such as ethylene oxide.
