Camfil dust collectors now have integrated safety monitoring filters (iSMF) to isolate toxic particles, preventing the discharge of any measurable emissions and are available with HEPA or ASHRAE certification.
These iSMF units are factory installed on Camfil APC's Farr Gold Series dust collector, minimizing the total footprint, as no additional ducts, transitions or supports are required. The dangerous particles are contained because the unit allows to locate the filters before the fan, keeping them under negative pressure.
They also prevent the collected dust from re-entering the work area if there is a leak in the primary filters and stops the flames that occur due to incidents of combustible dust, protecting the equipment located at the bottom.
These devices are monitored by changes in the differential pressure and can be programmed to generate alarms or turn off the dust collector.
The HEPA grade filters achieve a DOP efficiency of 99,97% in 0,3 micron particles. ASHRAE-grade Riga-Flo filters achieve an 95% efficiency and are rated for 2650 cfm (4248 cmh) per filter.
