Pulse Jet Pointers
Vol. 1, No. 2

Cartridge Collectors
The boss says "Solve this awful dust problem, but don't use up any floor space. Hang it in a low bay. Be sure there are no bags to change and don't spend any money." Sound familiar? We decided to at least take a shot at these demands with our new cartridge collector. A flyer on these unique collectors, which can be filed as a centerfold in your regular Beckert & Hiester pulse jet bulletin, is now available. Write us. You don't have a bulletin on pulse jets either? We will send that too! The new cartridges pack 200 sq. ft. of media into a 12%" dia. x 26" long cylinder. They can also tackle some nasty jobs, like lead fumes and welding smoke.

Getting Away From It
All With new restrictions on dust disposal, many installations are using contract dust haulers. Ever find yourself with the hopper outlets too close to grade level for the trucks to pass under? Rather than spending thousands to raise the dust collector and/or moving it into the yard so that trucks can be loaded from the hoppers direct, use a conveying system. These relatively new devices use a flexible spring wire screw to put material where you need it —around corners, straight up forty feet, whatever is required.
 

Back Talk From Your Dust Collector
Most dust collectors are very reticent. They say nothing about their troubles until it's all too late. We have dust collector control panels that "talk back" and let you know about these little problems before they become work stoppages. Page 14 of our Installation, Operation and Maintenance Instruction book shows the wiring diagram and bill of material—everything you need to make your dust collector "talk back"!
Trying To Change The Old Bag!
Time goes by regardless! Let our experienced crew do the dirty work in your dust collector. If your "bags are in rags," we have a complete array of felts and weaves to meet any requirement. Field engineers are also available for troubleshooting and consultation. Write us for field service scheduling and prices.

Getting Dried Out
Moisture in compressed air is an ever present problem. Most industrial compressors have only rudimentary coolers and separators. If there is at least as much air as oil and water in the 100 PSI line, most plant engineers learn to be satisfied. Pulse jet dust collectors are surprisingly tolerant of contaminated air. Certainly more so than air tools and cylinder operators. However, we usually get two strikes against us before ever getting to bat: 1 ) We are outside in the cold and 2) we are at the end of the line. The solution is quite simple:
First we put an inexpensive automatic moisture trap and/or a coalescing filter on the air header. Then in severe climates we "swallow" the air header and trap/filter into the clean air plenum
where it will stay warm. If ordered with new equipment, the added cost is negligible.

On retrofits, we offer electrical tracing materials and/or insulated header boxes with hinged covers for servicing the diaphragm valves. The boxes can be bolted and "ventilated" into the clean air plenum to circulate warm air into the valve area. 

For the most severe problems we offer desiccant or refrigerant dryers, but 99% of all pulse jets operate successfully year around with a simple drain trap.

For more information on removing water and oil from compressed air, ask us for Baston Bulletin R-14A. Also see our compressed air guidelines on page 8 of the installation manual (which we will also send on request).
