Backdraft and Downdraft for Explosive ST1 Dusts

SPC Backdraft

Designed for source capture. The SPC units are compliant with NFPA 652 standard for collection of ST1 Explosive Dusts.

Compact Backdraft Collector


This is a completely self-contained dust collector with very impressive suction. The filter is cleaned by means of an internal filter pulse mechanism, which uses a small supply of compressed air to ‘back wash’ the filter.

The standard identifies 7 specific requirements:

NFPA 652 requires all facilities handling combustible dust, even in NON-Classified environments, to use vacuum systems that meet very specific design requirements as laid out in NFPA 652 Section

  • The materials of construction must be conductive, except in a few specific circumstances.
  • Hoses must be conductive or static dissipative.
  • All conductive components, including wands and attachments, must be bonded and grounded.
  • Dust-laden air must not pass through the fan or blower.
  • Electrical motors must not be in the dust-laden air stream unless listed for Class II, Division I, locations.
  • Paper filter elements aren’t allowed for picking up liquids or wet materials.
  • Vacuum systems used for metal dust must meet the requirements of NFPA 484, which is the standard for combustible metals.

Compact Downdraft Tables


Made in the USA, PDC Portable Downdraft Benches are engineered for effective, economical control of dry dusts, fume and smoke that is generated from sanding, polishing, grinding and more. Ideal for light to moderate concentrations of dry contaminants, the Downdraft Benches draw fumes, vapors, smoke and particulate down and back- away from the operator’s breathing zone. Highly efficient cartridge filters trap particulate down to .5 microns, while pulse-jet compressed air blasts keep filters clear and operating at optimum efficiency.
