Retrofit & Rebuild Cartridge Dust Collectors

95% of all existing pulse-jet dust collectors are retrofit candidates. Applies to cartridge, pleated filter and pleated bag collectors.

• Increase efficiency and lower particulate emissions coming from the dust collector.
• Increase cartridge filter life 3 to 10 times.
• Lower operating cost by 30-60%.
• Use half the current number of cartridges or increase collector capacity by up to 75%.
• Lower power consumption by 25-40%.
• Upgrade to the best available technology
• Most economical approach, usually purchased in operating rather than capital budgets.
• Attractive payback in just over a year, many times less.

• No risk. Modifications installed and running before invoice is due. No special requirements or training required.

Symptoms to look for:

1. Pressure drop over 3 inches water column across filter elements.

2. Cartridge life less than 12 months.

3. On tandem cartridge sets, dust piles up on upper sections of cartridges.

4. Operating weight of cartridges are more than 4 lbs over the weight of a new cartridge.

5. Dust build up in horizontal duct runs.

The Problem: There are serious flaws in equipment design by all major baghouse dust collector suppliers.

The Solution: QAM’s exclusive Retrofit / Rebuild and consulting service. Apply ten year old proven advanced technology, with over 500 units in service, to the conventionally designed dust collector. Alternatively, purchase one of the very few well designed advanced technology dust collector systems available today.

LAB TESTING: QAM’s test facility will examine the cartridge for bridging, presence of moisture or condensation, evidence of dust leaking to the clean side, oil in the media, permeability of the media, strength tested, type of dust in that application and it’s characteristics.
