Self-Cleaning Portable Downdraft Workstations

Looking for a low-maintenance downdraft system that is portable and powerful? You’ve found it!

The Small Portable Cartridge DownDraft Bench (SPCB) is designed to provide efficient, cost-effective control of dry dusts, fumes, and smoke generated from sanding, polishing, buffing, grinding and other processes. Typically used for light to moderate concentrations of dry contaminants, the SPCB- series of workstations are a low-maintenance downdraft system that is portable and powerful. The top is an aluminum surface to protect against parts that cannot be scratched, can support a table load of 50 pounds per square feet maximum, and it has a back enclosure with hinged side wing panels to adapt to most processes.

The filter in the SPCB units is a 99.97% HEPA-like efficiency pleated Flame Retardant media cartridge. The cleaning system is a manual push button filter cleaning system. The SPCB portable downdraft workstations are designed to be powered up as soon as you receive them by offering a power cord and switch operating at 110 volts. Optional rubber mats are available for the placing on the table top.
