GENERAL INFORMATION
Made primarily of 12 gauge metal construction, Airex Industries’ downdraft tables are designed for industrial applications, including the removal and filtration of dust, smoke and other airborne pollutants. Hazardous materials are removed before reaching the worker-breathing zone. The built in motor/blower and reverse pulse self-cleaning filter system requires virtually no maintenance while prolonging filter life and unit efficiency. Front or side filter access, deep dust trays, optional casters for ease of movement, multiple grating options, as well as different interchangeable top sections allows the downdraft tables to be tailored, customized to your/any/very specific needs. This unit complies with environmental clean air regulations.
ADVANTAGES
VERTICAL CARTRIDGE DESIGN
Due to its vertical cartridge design, the DDT series of downdraft tables, unlike most of its competitors, does not require any semi circle baffles to prevent the unnecessary accumulation of dust on any particular side of the cartridges. Dust particles are spread and filtered equally on all sides of the media; unlike the horizontal cartridge design where you can lose up to 30% of the effective filtering surface, Airex Industries’ DDT series of dust collectors maintain a 100% of its filtration area all the time.

FAST, SIMPLE AND SAFE CARTRIDGE REPLACEMENT
- The entire replacement of the set of cartridges is done from outside the downdraft table and requires no tools.
- The cartridge is provided with a rectangular adapter that simplifies the manipulation of the cartridge, and eliminates installation errors.
MODELS
There are two base models for the DDT series: the DDT 75 and the DDT 100. Custom downdraft tables are not an issue and will most probably be better fitted for your particular needs.
THEORY OF OPERATION
HOW [DDT] DOWNDRAFT TABLES WORK
The Airex Industries self-cleaning down draft table helps eliminate smoke and dust form the workers breathing zone. The work surface of the table uses a high face velocity of downward air to pull debris and pollutants away from the worker and towards a set of highly efficient filters. The air is then filtered and returned to the shop. The self-cleaning system uses a blast of compressed air in the reverse direction to dislodge the debris and can be activated automatically or manually. The solids are then collected in a dust drawer. Custom downdraft table sizes are available upon request.
