FilterBox 12A ePTFE

Automatically cleaned for medium to heavy welding fumes and for applications like sticky and hygroscopic non-combustible dust.

The FilterBox 12A ePTFE is specially designed for hygroscopic and sticky substances in humid environments, but also suitable for different welding applications such as MIG, MAG, FCAW, MMA (Stick Welding) including high alloy.

The unit has an advanced filter control system indicating the pressure drop with a series of LED's as well as on the LCD display. When the air flow is too low an audial alarm precedes the automatic, motorized cleaning sequence. An integrated silencer reduces noise from the fan and outlet air. Additional protection from harmful particles is provided if a HEPA filter is installed (optional).

Note! FilterBox is not for use in environments where combustible dust or gases are present, and it is not for use in filtering combustible dust or gases.
