TOP-MOUNTED HEPA · MODULAR DUST COLLECTION
HEPA Dust Collectors
Top-Mounted HEPA.
Save Valuable Factory Floor Space.
Combine dust collection and HEPA final filtration in one vertical assembly. Top-mounted HEPA housings use available height to save floor space, while complete modules can be combined for larger airflow requirements and lower particulate emissions.
For suitable applications, filtered air can be discharged directly into the workshop, retaining heated or cooled air and reducing energy loss through outdoor exhaust. Where permitted, this also removes the need for an outdoor exhaust stack for the dust collection system, creating a cleaner site appearance.
- Top-mounted HEPA — save floor space
- Modular combinations — suit your airflow
- Final filtration — lower dust emissions
- Direct indoor discharge — retain heating & cooling
Direct indoor discharge is subject to dust characteristics, other contaminants and local requirements.
What Is a HEPA Filter?
High-efficiency final filtration for industrial dust collection.
HEPA stands for High Efficiency Particulate Air. A HEPA filter uses densely pleated fibrous media to capture fine airborne particles. In our dust collection systems, it provides a final filtration stage after the primary collector, capturing residual particles for lower outlet dust concentrations.
H14 is our usual choice; H13 is available on request.Our H14 HEPA final filters provide a filtration efficiency of ≥99.995% at the most penetrating particle size (MPPS) according to EN 1822. Combined with high-efficiency primary dust collection, they further improve overall dust removal efficiency and reduce particulate emissions. H13: ≥99.95% at MPPS.

HEPA filters are available in many shapes and sizes. The ratings above describe our commonly selected filters; the final specification and filter quantity depend on the project.
High-Efficiency Primary Collection Matters
The primary dust collector must remove most of the dust before air reaches the HEPA stage. Our polyester cartridges with a PTFE membrane help achieve low residual dust loading and little or no visible dust in suitable applications.
Under suitable operating conditions with effective primary filtration, HEPA service life can reach one year or more. Actual life depends on residual dust loading, operating hours, airflow and moisture; visual clarity alone does not verify air quality.
Replace — Do Not Pulse-Clean
The HEPA filters used in these systems are replaceable consumables. They are not pulse-cleaned or water-washed.
As dust accumulates, pressure drop increases and available airflow may fall. Replace the filter at its specified service limit, or sooner if it is damaged or fails an integrity check. Maintain effective seals and monitor differential pressure.
Operating Conditions
Protect against water. Our standard HEPA filters must be protected from liquid droplets and condensation. Wet dust collectors require upstream mist elimination before the final filters.
Match the operating duty. Select filters to suit the airflow, temperature and pressure drop. High-temperature HEPA options rated up to 280°C are available for applications such as high-temperature baghouse dust collectors. Temperature limits and filtration grades depend on the selected model. Prevent sparks from reaching the filter media.
Two-Stage and Multi-Stage Filtration
A HEPA dust collector combines a conventional primary collector with HEPA final filtration. Cartridge and baghouse collectors can both include an activated carbon stage. Wet collectors use F9 fine filters before HEPA, with activated carbon added when required.
Two-stage particulate filtrationCartridge or Baghouse Collector → HEPA
Three-stage filtration optionCartridge or Baghouse Collector → Activated Carbon → HEPA
Three-stage wet filtration optionWet Collector → F9 Fine Filters → HEPA
Four-stage wet filtration optionWet Collector → F9 Fine Filters → Activated Carbon → HEPA
Wet configurations include upstream mist elimination to protect the downstream filters. The number of F9 filters is matched to the required airflow; F9 is a fine-filter grade, not HEPA. Activated carbon can be selected for suitable gas or odor contaminants. Filter stages are configured to suit the application.
Vertical Cartridge Dust Collectors with HEPA
Top-mounted final filtration. Modular capacity. Proven industrial applications.
DHC-H Series. A HEPA housing sits directly above each vertical cartridge collector module, combining primary dust collection and final filtration in one assembly. This uses available height to save the floor space needed for a separate HEPA unit. Modules can be combined to meet larger airflow requirements.
Dust-laden air → cartridge filtration → HEPA final filtration → filtered-air outlet.
Airflow & Main Components
Air enters the settling chamber below the cartridges, avoiding direct impact on the filter media. Larger particles settle into the hopper, while finer particles travel upward to the cartridges and then the top-mounted HEPA stage. Pulse-jet cleaning serves only the cartridges.

DIRECT INDOOR DISCHARGE
Shot Blasting — External Fan with Acoustic Enclosure
The fan is installed separately from the dust collector in a floor-mounted acoustic enclosure to reduce noise. After cartridge and HEPA filtration, the filtered air is discharged directly into the workshop.
External fan with acoustic enclosure — direct indoor discharge.
DIRECT INDOOR DISCHARGE
Shot Blasting — Integrated Fan with Acoustic Lining
The fan is integrated inside the dust collector, with sound-absorbing lining on the enclosure walls to reduce noise. This compact arrangement discharges filtered air directly into the workshop after cartridge and HEPA filtration.
Integrated fan with acoustic lining — compact, direct indoor discharge.
DIRECT INDOOR DISCHARGE
Grinding — Direct Indoor Discharge
Installed inside the workshop, the vertical cartridge collector captures grinding dust. The HEPA stage removes residual fine particles before the filtered air is discharged directly indoors, helping retain heated or cooled workshop air.
Direct indoor discharge helps retain heating and cooling energy.
DIRECT INDOOR DISCHARGE
Electrostatic Powder Coating — Direct Indoor Discharge
Cartridge filtration captures powder overspray from electrostatic powder coating, followed by HEPA final filtration. The collector is installed indoors and discharges filtered air directly into the workshop.
Direct indoor discharge — retain conditioned workshop air.
OUTDOOR EXHAUST · NO AIR RECIRCULATION
Lead-Acid Battery Manufacturing — Lead-Dust Extraction
For lead-dust extraction in lead-acid battery manufacturing, HEPA final filtration further reduces the outlet lead concentration. Test reports for the illustrated application record a lead concentration of ≤0.1 mg/m³. Because lead is toxic, the treated air is exhausted outdoors through a stack; it is not recirculated into the workshop.
Tested outlet lead concentration: ≤0.1 mg/m³.
OUTDOOR EXHAUST · NO AIR RECIRCULATION
Lead-Dust Collection — HEPA Final Filtration
This lead-acid battery installation uses cartridge collection and HEPA final filtration to reduce lead emissions. Application test reports show an outlet lead concentration of ≤0.1 mg/m³. The filtered air continues to discharge outdoors through an exhaust stack, with no indoor air return.
Lower lead emissions with outdoor stack discharge.
Direct indoor discharge is selected for suitable applications according to dust characteristics, other contaminants and applicable requirements. The lead results above describe tested applications; project emission limits depend on the location and process.
Downflow Cartridge Dust Collectors with HEPA
Two top-mounted HEPA arrangements. One compact filtration system.
EHCDT-H Series. Our downflow cartridge dust collectors combine inclined filter cartridges with top-mounted HEPA final filtration. Choose a separate HEPA housing for each collector module or a shared HEPA housing across several modules. Both arrangements use the space above the collector, eliminating the floor space required for a separate HEPA unit.
Airflow & Main Components
The inclined cartridges capture the main dust load. Air then passes through the top-mounted HEPA stage to remove residual fine particles before discharge. Pulse-jet cleaning removes dust from the cartridges into the hopper and collection bin; the HEPA filters are replaced when required.

INDIVIDUAL HEPA HOUSINGS
Two Modules, Each with Its Own HEPA Housing
Each upper HEPA housing and the cartridge collector below form one complete filtration module. The illustrated dust collector combines two of these modules in a single assembly.
One HEPA housing per module — two complete modules combined.
SHARED HEPA HOUSING
Four Modules Beneath One Shared HEPA Housing
The HEPA filters serving four cartridge collector modules are installed in one common housing across the top of the collector. This brings the final filtration stage together in a single upper assembly.
Four collector modules — one shared top-mounted HEPA housing.
Flat Baghouse Dust Collectors with HEPA
Modular bag filtration with an integrated HEPA final stage.
EHFBC-H Series. Top-mounted HEPA housings combine with the flat baghouse modules below to form a compact two-stage dust collector. Modules can be combined to suit the required airflow, while the HEPA stage uses the space above the collector without a separate filter unit on the floor.
Airflow & Main Components
The flat filter bags capture the main dust load. Filtered air then passes through the HEPA stage above each module before entering the common outlet duct. Pulse-jet cleaning serves the bags; the HEPA filters are replaced when required.
