Today’s downdraft tables come in all types of sizes and options. Some tables have backdraft to optimize collection for grinding applications, spark baffles for welding and cutting applications and regain overhead hoods for contaminate containment. Downdraft tables are ideal for welding, cutting, grinding, and polishing applications and have additional features that can be customized to suit your process.
The heavy-duty SDB Downdraft Bench offers a large work surface, high-capacity dust drawers and a downdraft velocity up to 200 fpm. It is typically used for grinding, polishing, hand sanding and dry buffing. The SDB bench features an automatic pulse cleaning system with four Advanced Nanofiber Filtration Technology cartridge filters, including an option for flame retardant media. It can support 75 lbs. per square foot on its 80″ wide x 55″ deep work surface, and comes standard with a 3 HP motor, 230-460/3/60.
The Filter 1 Benchtron Downdraft/Backdraft Workstation removes dust, fumes, and smoke from sanding, grinding, buffing, or welding of metals, composites, fiberglass, plastics, or wood. The Benchtron meets OSHA requirements for respirable dust down to .05MG/M3, with adjustable suction velocities of 150 to 800 FPM in the “working zone.” High efficiency filters remove 99.9% of all particles 1/2 micron and larger. The unit features automatic self-cleaning, flourescent lighting, and the Regain Air, “Push/Pull” technology pioneered by Filter 1 to provide a blanket of clean air in the “breathing zone.”
The standard design includes a 3 phase TEFC motor with starter and rubber vibration mount, a magnahelic guage, and sound insulation to less than 78 db. The Benchtron is available in configurations of one work surface or two, for sitting or standing.
This down draft table features ultra-efficiency nanofiber media filters, work surface grating, suction velocities of 150-300 FPM across the entire work surface, and automatic power pulse cleaning. The unit is self cleaned on a solid state timer which can be activated by the operator regardless of whether the fan is off or on. The removed dust falls into pull-out drawers in the bottom of the cabinet. Rated at MERV 15 efficiency, the Downtron’s cartridge filters are constructed of nanofiber media, tightly meshed of ultra-fine fibers 300-500 nanometers in diameter, screening out sub-micron particles and resulting in easy release of the dust cake during the cleaning cycle. Because the nanofiber filter media operates at a 40-60% lower pressure drop than traditional cartridge medias, the Downtron industrial downdraft table features lower energy consumption and a longer filter life.
The Filter 1 Downtron table is built of heavy gauge carbon steel to withstand hard use. It is sized to fit the application and provides the flexibility needed for “cell manufacturing.”
The Weldtron backdraft workstation removes fumes from the student’s breathing zone with a generous air flow of 2000 CFM. The state-of-the-art filters are designed to last an entire school year without loss of airflow or servicing to insure worry-free capture and filtration of the hazardous fume produced by welding.
Other special safety features include:
Shielded sides to prevent eye-damaging flash or showers of sparks that could otherwise injure fellow students.
Insulated table: the work surface of the Weldtron is rubber-mounted for insulating against any extraneous welding currents and protecting against damage to the unit.
Ground fault plugs for electric hand tools or extra lighting.
The downdraft and backdraft work bench, DraftMax, is a combination of a welding table, an extraction and filtration system. The compact downdraft table can be placed everywhere, e.g. inside a welding booth or connected to ductwork. The DraftMax is suited for many applications, like welding, grinding and plasma cutting.
The extraction system removes fumes and dust directly from the breathing zone of the welder through the working surface and optional backdraft panel. The backdraft kit is recommended if you work with a heat source, like welding. Fast-rising welding fumes can only be captured effectively by a downdraft and backdraft combination.,
