When mobility, flexibility and a compact footprint is key, a mobile solution is the often the best way to avoid contaminant exposure. Nederman FilterBox range of mobile dust and fume extraction units are easy to move around your factory to wherever the extraction is needed.

Ideal for use in MIG welding, TIG welding, and other GMAW welding methods, the FilterBox TWIN A+ is equipped with two 10 ft, 6" NEX-MD extraction arms with spark protectors and a powerful 3.0 hp (2.2 kW) N29 fan for a maximum air flow capacity of 2 x 500 CFM (2 x 850 m3/h). The nanofiber media technology utilized in the extra large 183 ft2 (17 m2) cartridge is ideal for frequent welding. It offers significant performance advantages like higher efficiency (MERV 15) and surface loading properties which results in more effective filter cleaning and longer cleaning intervals. Advantages that will impose benefits in terms of filter life, productivity and lower cost of ownership.

The unit has an advanced filter control system indicating the filter load with a series of LED's as well as differential pressure readings on the LCD display. When the air flow is too low an audible alarms warns the start of the automatic, motorized compressed air cleaning sequence. An integrated silencer reduces noise from the fan and outlet air.
