Farr Air Pollution Control (Jonesboro, AK) has released its Gold Series GS4M Mini dust collector, ideal for use indoors because of its small footprint, especially where noise and space constraints are a concern. The unit controls emissions from small airflow applications, up to 2,000 cfm. The dust collector is complete with a low-noise fan (<70dB), controls, motor starter, filters, and cleaning system. Particles are collected through tour flame-retardant filter cartridges with 788 total sq. ft. of media rated at 99.99 percent efficiency on 0.5 micron particles. The GS4M uses a 3 horsepower fan motor designed to handle 1,000 cfm at 9" w.c. or 2,000 cfm at 5" w.c. static pressure. A number of optional features are available, including an explosion vent, different filter media, a dust hopped, and spark-resistant flex hoses.
