The main thing I would like to see improved would be for the system to be quieter during operation; not from the standpoint of the mechanical portion, but at the workstations where the air (&dust) is removed. The greater the suction, the noisier it is.

~Dennis C, Research & Development, Seattle/Tacoma, WA

Easier access to filters, better spark traps, better use of energy on motors, lower static pressure inside the units, longer filter life, fewer chances of fires, better compliance with explosion vents

Answers:

Take account of any off-line time and this includes cleaning cycles. Also consider what happens to the overall process if the dust collection system is off-line, i.e. would the whole process be affected and to what degree?

~M H, Engineering Consultant, Johannesburg, RSA

Most errors are with the ducting system leading to the collector, with insufficient velocities to keep dust in suspension, or with velocities which cause the static pressure design levels to be exceeded.

~Gregory B, Engineer, Golden, CO

Specify accurately the operating conditions, especially variable flow conditions and particle size distribution, and acid components in the gaseous stream. For dry systems, stay well above the dew point.

~Romualdo Salcedo, CTO, Professor, Porto, Portugal

Do not increase the dust capturing points from the original concept; attend for maintenance as per operator's manual, clean the compressed air for filters cleaning, to be in knowledge that a dust collector is capable to manage fine dusts fine emissions only.

~Javier V, Marketing/Sales, Tlalnepantla, Mexico

1- It is preferable to use a cartridge filter, upstream of blowback gas (eg: Nitrogen,instrument air etc.) which is used for blowback operation, prior to entering main dust collector housing.

Dust collectors should not be treated as one fits all kinds of equipment. Small changes in process/material etc may greatly affect dust collector performance.

~Narendra L, Project Manager, Bakersfield, CA

If you plan to not return the air into the building allow for air make up into the building especially if the building is closed during colder weather.

Don't buy a "Cookie Cutter" baghouse. Each application is different, and you should have your collector designed from the bottom up to meet your needs.

~Dominick D, Marketing/Sales, Bloomingdale, IL

In high temperature dust collectors (more than 150C), best is to use filter's materials that resist up to the next step of temperature (f.e. 200C).

Never jump into a band wagon solution. Just because John has a good dust collector for his problem, you shouldn't copy the same for your problem.

~Christopher S, Maintenance Head, Imus, Philippines

Try to remember that every thing in this planet interacts because of interfaces component of each process. Also remember that energy is paid for ever, it doesn't matter if one is producing some or not, the watch will be always running and the result will come off at the end of the month, showing the bill to pay for.

~Paulo V, Engineering Consultant, Sao Jose dos Campos, Brazil

Air-to-media ratios are the most important thing when sizing a collector. If the wrong ratio is used, the filter life will be very short.
