FAQ

Yes. AQE evaluates underperforming dust collection systems to identify the cause of poor capture, excessive dust, high differential pressure, inadequate airflow, filter problems, duct restrictions, or other performance issues. Depending on the condition of the system, the solution may involve maintenance or repairs, filter replacement, airflow adjustments, ductwork modifications, equipment upgrades, or a larger system redesign.

Maintenance frequency depends on the collector, dust characteristics, production schedule, operating hours, and manufacturer requirements. Routine inspections should monitor filter condition, differential pressure, pulse-cleaning performance, compressed-air supply, hopper and discharge operation, ductwork, fan performance, and visible emissions. Tracking changes in system performance can help identify problems before they lead to downtime or production issues.

Low airflow can result from loaded filters, inadequate filter cleaning, blocked or undersized ductwork, closed dampers, fan problems, incorrect fan rotation or speed, or changes to the production process. Troubleshooting should look at the entire system—from the capture point through the ductwork, collector, fan, and discharge—not just the dust collector itself.

High differential pressure generally indicates increased resistance through the filter media or another restriction in the system. Possible causes include loaded filters, ineffective pulse cleaning, unsuitable filter media, excessive airflow, wet or sticky dust, or duct and hopper restrictions. The correct operating range depends on the collector and application, so pressure trends should be evaluated against the equipment's design conditions rather than relying on a single universal number.

Filter replacement should be based on system performance and filter condition rather than an arbitrary calendar interval. Increasing differential pressure, declining airflow, ineffective cleaning, damaged or leaking filters, and visible emissions can all indicate that filters require attention. AQE can help determine whether filter replacement, a different filter media, or another system correction is the appropriate solution.

Dust emissions can result from damaged or improperly seated filters, collector leaks, overloaded filters, inadequate airflow, duct leaks, poor source capture, or problems with dust discharge. Finding the location and conditions under which dust appears is an important first step in determining whether the problem is at the collection point, ductwork, collector, or discharge system.

Yes. AQE supplies replacement filters, parts, and components for industrial dust collection and air filtration equipment. We can help identify the correct replacement based on the collector model, filter dimensions, media requirements, operating conditions, and application rather than simply matching a part number.

Yes. AQE designs dust collection and source-capture systems for new equipment, production expansions, facility modifications, and process changes. We evaluate the equipment being served, contaminant characteristics, required airflow, duct routing, collector selection, fan requirements, controls, and applicable safety considerations.

Yes. AQE can help evaluate dust collection systems where combustible dust may present a fire or explosion hazard and identify appropriate engineering controls and protection measures. Combustible dust systems require consideration of the material characteristics, collection equipment, ductwork, ignition sources, housekeeping, and applicable fire and explosion prevention requirements. OSHA specifically recommends engineering controls and properly designed dust collection systems as part of combustible-dust hazard management.

Yes. AQE designs and coordinates industrial ductwork for dust, fume, smoke, and mist collection systems. Proper duct sizing, routing, airflow, velocity, balancing, and connection to the source are critical to maintaining capture performance and preventing problems such as settling, excessive pressure drop, and inadequate airflow.

Yes. AQE provides project coordination from system design and equipment sourcing through installation and ongoing service. We work with qualified installation contractors and coordinate the installation to ensure the system is properly implemented, commissioned, and supported after startup.

AQE provides industrial air quality solutions for manufacturing and process environments including aerospace, machining, metal fabrication and welding, blasting, woodworking, food and spice processing, chemical processing, pharmaceutical, pulp and paper, and educational facilities with wood and metalworking operations.

AQE primarily serves customers throughout California, Wisconsin, Nevada, and Illinois, with projects supported nationwide through referrals and project-specific coordination.

NFPA 660 establishes requirements for managing fire and explosion hazards associated with combustible dust. For facilities with combustible dust, compliance can affect dust collector design, explosion protection, ductwork, isolation, fire protection, and other system components. AQE can evaluate existing and new dust collection systems to identify potential hazards and coordinate engineered solutions that address applicable NFPA requirements.

If your process generates combustible dust, NFPA 660 may apply to your dust collection system and facility. Applicability depends on the material, process, equipment, and hazard characteristics. AQE can help evaluate your dust collection system and identify where additional engineering, testing, or protection measures may be needed.
