Ventilation system

Is this system already in a clean room environment?

Sir:

Dust Collection Systems makes a dust collector that will help. They specialize in a line of small capacity collectors for small airflow needs for chemical and food processing plants.

What makes DCS special is their housing are corrosion resistant and are ideal for caustic and corrosive chemicals. The standard housing is good for abiant air temperatures, but there are alternative materials that can be used to give up to 200 – 210 degree f and 300 degrees f. I think that 200 just past the upper limits of your needs.

For the past five years, they worked to developed a new process and material that allows them to sell their collectors for about 50% of what other companies in the US are selling their units. They have been very popular in food and chemical plants, because the housings have been approved by plant inspectors for food-grade use.

They have a 150mm stub tube connection for a short length of flexible hose.

The filter they use is a pleated spun bond polyester cloth, but they have been experimenting with porous plastic filter media, but the media has an upward temperature limitation of !60F.. We are all very excited about our latest improvement. The filter will last three times longer than our standard filter (10 year guarantee) and can have a collection efficiency down to .00004 grains per cubic meter (I think this almost rivals HEPA's performance).

We are working at a plant in western US that originally wanted to have a central dust collection system but changed their minds very quickly when we made our proposal

The original system was a 3,000 cfm blower with 20hp motor, a Donaldson DFO with 8 oval cartridges, (carbon steel too) with 100 feet of 12 inch main duct that reduced at each of the six branches. Each branch was 4 inches pulling about 350 cfm. They had three quotes for equipment and installation ranging from slightly under $30,000 to $39,000.

We used three smaller dust collectors connected via 4 inch flexible duct to two machines and used a 2hp blower per duct collector. We supplied the collectors and blowers and the customer furnished the hose and had the supporting brackets local fabricated by his maintenance department. The project was cost for the equipment and the installation was just under $15,000 and they were able to recover the airborne product captured by the collector and return it to the process.

Contact me by the end of this week if you are interested.

Sir,

You told that you have a packed scrubbing unit for exhaust. I understand that you may cause any other problems at this scrubber, if you send dusty air. Why don't you think to change the scruber with an un-packed type ? If you prefer, you can contact with me. We have many experiences about these kind of applications.
