General Specifications

Characteristics The Stand Alone Portable Filtration System (SAF) provides maximum versatility for air pollution control. The portable dust and fume extractor ships complete on caster wheels and connects easily to existing ducting and hood systems. Self contained air filtration solution; no outdoor exhausting necessary. Patented DualDraw design for Panel Nose ™ fume arm attachment: even distribution of airflow across a perforated surface.
Filtration Systems Choose between dust collection (including combustible aluminum dust), smoke or fume removal, and HEPA filtration. Each smoke filtration system comes with a cleanout tray, a magnetic gauge to monitor filter cleanliness, and an easy-to-remove access door for filter maintenance.
 • Dust  For dust producing applications, the portable fume extractor is configured with a prefilter and a final dust bag filter. A washable metal spark arrestor is also used for a sparking application. The standard air prefilter is 40% efficient to a 0.7 μ and the final dust bag filter is 85% efficient to 1.0 μ.
 • Smoke/Fume For welding applications, the unit is configured with a prefilter, final filter, and washable metal spark arrestor for safety. The standard prefilter is 40% efficient to a 0.7 μ and the final filter is 95% efficient to 0.7 μ. For fume control, 12 lbs. or 60 lbs. of activated carbon or a potassium permanganate/carbon blend filter is used depending on the volume and the chemistry of the fume based on MSDS reports.
 • HEPA Optional High Efficiency Particulate Air filter are available for maximum filter efficiency. HEPA filters are 99.97% efficient to 0.3 μ.
Available Sizes The footprint of the SAF for dust is 40” D x 25” W x 80” H. For fumes the footprint is 25” D x 25” W x 48” H. Flexible design construction allows customers to cost-effectively specify non-standard sizes.
Optional Panel Nose ™ The optional Panel Nose ™ is designed to provide operators with an easy solution to collection needs within a small space. The capture area is 6.25” D x 24” W, well-suited for operators performing their application in a straight line
pattern. The nose comes standard with easy-to-use grabber bars for simple positioning.
Cabinet 12-16 gauge modular body construction.
Finish Electro-galvanized metal finish – non-glare. Powder coat paint finish available as an option.
