5000 CFM Wet collector will be used with a 72" x 30" DDT for combustible dust that is fully NFPA and OSHA compliant.

What will happen if you exceed the air to cloth ratio for filters in a dust collector? - Class is in session!

If you exceed the air-to-cloth ratio (ACR, also called air-to-media ratio) in a dust collector — meaning you push more airflow (CFM) through the filter media than it’s designed for — several negative things happen, usually in this order:

* Immediate drop in filtration efficiency

Higher face velocity forces dust particles deeper into the filter media (or straight through it in extreme cases).
Fine particles that would normally form a dust cake on the surface now pe*****te the media → higher emissions out the clean air plenum (visible stack plume, bypass, or failed opacity/emission tests).

* Rapid increase in differential pressure

The same amount of dust is now loaded onto less effective surface area.
Pressure drop across the bags/cartridges rises much faster → the system runs at higher static, even right after cleaning.
Fans work harder, energy costs go up, and you may trip high-static alarms or shut down.

* Reduced filter life

Excessive velocity causes flex fatigue and pinhole leaks or tears in bag filters.
In cartridge collectors, it leads to media compaction, blinding, or cracks around the pleats causing bypass.
Typical result: filter replacement interval drops from years to months.

* Poor rotopulse cleaning

At high ACR, the dust cake doesn’t release properly during cleaning pulses because the air is pushing the cake into the media instead on the surface and letting it drop.

* Reduced dust handling capacity in the hopper

Because cleaning becomes ineffective, more dust stays on the filters instead of dropping into the hopper.

* Bottom Line

Exceeding the air-to-cloth ratio is the fastest way to destroy a dust collector’s performance and filter life. It’s almost never worth it to “just turn up the fan.” If you need more airflow, you have to add filter area (more cartridges, or a second module) or switch to a higher-ratio media/technology that is specifically rated for it.

Micro Air is thrilled to announce the launch of the redesigned WC2500, now in
full production as part of the Hydromax lineup. These advanced wet dust collectors are engineered to mitigate risks of fire and deflagration of combustible dust, ensuring safer operations while minimizing costly repairs and downtime.
Key Features of the WC2500:
 Delivers a true 2,500 CFM for superior performance
 Constructed from durable 304 stainless steel with a single sump
 Powered by a 7.5 HP motor and forward inclined non-sparking
blower that is fully removed from the dirty air stream
 Equipped with UL 508A-listed controls and NFPA compliant
interlocks for enhanced safety and reliability
 Feature direct level capacitance sensors, eliminating water level concerns
 Available in industrial stainless steel or with an optional
black marine-grade epoxy coating
 Offer a full range of optional attachments, including silencers, HEPA filters, A-Frame after-filters, and powered-off gas blowers.
Micro Air’s Hydromax Lineup sets a new standard in dust collection technology,
providing businesses with reliable, high-performance solutions to maintain safe
and efficient operations. Ask about a DEMO
