Dust Collectors; Old vs New Technology

OLD TECHNOLOGY

•85-90% of the market, sold by all the big conventional suppliers.

•Handle most dust loadings, high temperature.

•Circa 1963; compressed air powered cleaning by rows of bags, venturi accelerated the jet to project to bottom of bag. Filter ratio 10:1 or less, dependent on application. Dust penetration (puffing) unacceptable for re-circulation to the work area.

•Circa 1971; “generic” design, modified to use 10-foot bags. Major design flaws led to selection strictly by filter ratio. Most operated at 4-6:1 ratio. Pressure drop is 6-8”wc. High compressed air consumption with higher cleaning frequency.

•High velocity dust impinges on adjacent bags which are too close together.

•The entire industry copied the same design and very little has changed to this day.

NEW ADVANCED TECHNOLOGY

•Ultra-Flow  by  QAM, circa 2003, are the 6th evolution of the advanced technology.

•Circa 1979; “Advanced Technology” first appeared. Proven technology but little known.

•95% less dust emissions, allows for re-circulation to work area.

•25-40% lower power consumption.

•50-80% lower operating and maintenance cost.

•30-40% smaller footprint.

•No venturi to restrict flow, low velocity - high volume jet = gentle but powerful cleaning pulses = no penetration & complete cleaning. 200% increased bag filter life & uses half as many bags.

•High, side inlet eliminates “can velocity”.

•Supersonic nozzles; very high energy cleaning pulse and only 1/4 compressed air consumption.

•Runs at 18-24:1 filter ratio, independent of process & dust loading.

•Runs at 1.5- 3”wc(max) pressure drop.
