01Structure Overview
Inside the EHRBT Round Baghouse
Two 7US project photos show the collector before filter installation and after installation on site. Circular filter mounting openings sit within the modular housing; the completed unit includes a hopper, access ladder and connected ductwork. The arrangement is configured for each project.
02How It Works
How the EHRBT Round Baghouse Works
Follow the airflow and cleaning path through the illustrated collector. Numbered callouts identify the principal components of this configuration.
01 · Dust-Laden Air
Air Enters Through the Inlet
Dust-laden air enters at the lower inlet (7) and moves through the collector toward the round filter bags (5).
02 · Filtration
Dust Stays on the Bags
Air passes through the filter media while dust is retained on the bag surfaces. Filtered air is directed to the clean-air outlet (10).
03 · Pulse Cleaning
Dust Falls to the Hopper
Pulse valves (3) release compressed air from the air header (4) to clean the bags. Dislodged dust falls into the hopper (11) and exits through the discharge valve (8).
04 · Service Access
Access for Inspection
The inspection door (1) provides access to the upper section. The safety railing (2) and access ladder (9) support routine inspection of this illustrated configuration.

03Round Filter Bags & Cages
Bag and Cage Installation
Round filter bags are supported by wire cages and fitted into the openings of the tube sheet. The bag, cage and mounting details are selected to suit the collector and the operating conditions.
01 · Filter Media
Round Filter Bags
Dust is retained on the outside of the filter fabric as air passes through the bags. The media is chosen for the actual dust, operating temperature and process conditions.
02 · Internal Support
Wire Cages
A wire cage supports each bag and helps it maintain its shape during filtration and pulse cleaning. Cage length and diameter must match the selected bag and the collector layout.
03 · Mounting
Tube-Sheet Openings
The photo shows the bag openings arranged across the tube sheet. The bag connection and cage fit are checked against the opening size so the filter assemblies seat correctly.
04 · Site Installation
Placing Bags and Cages
Technicians position each bag and its support cage from the clean-air side. The white fabric bags and the upright cages in the photo show different stages of installation.
05 · Service Planning
Room for Replacement
Round bags and cages need clear access above the tube sheet for installation and later replacement. The required maintenance space depends on the bag length and the project arrangement.
04Standard Module Selection
Select the Filter Area, Then the Module Arrangement
Start with the dust and operating conditions, then choose the filter media and design air-to-cloth ratio. Calculate the required filter area from the project airflow before deciding how many base modules fit the available site space.
01 · Operating ConditionsCharacterize the Dust
Confirm dust properties, loading, temperature and process conditions before selecting the filter media.
02 · Required AreaSize for the Airflow
Use the required airflow and the selected design filtration velocity to establish the required filter area.
03 · ArrangementChoose and Combine Modules
Compare bag length, module count, site dimensions and overhead space for bag replacement.
54-Bag Base Module
Standard bag diameter: Ø155 mm
| Bag size | Bags | Nominal filter area |
|---|---|---|
| Ø155 × 2.0 m | 54 | 52.6 m² |
| Ø155 × 2.2 m | 54 | 57.8 m² |
| Ø155 × 3.0 m | 54 | 78.9 m² |
81-Bag Base Module
Standard bag diameter: Ø155 mm
| Bag size | Bags | Nominal filter area |
|---|---|---|
| Ø155 × 2.0 m | 81 | 78.9 m² |
| Ø155 × 2.2 m | 81 | 86.8 m² |
| Ø155 × 3.0 m | 81 | 118.3 m² |
Nominal area is the cylindrical bag side area: π × bag diameter × bag length × bag count. These values are reference geometry, not a guaranteed effective area or airflow rating; final selection depends on bag construction, media and operating conditions.
Other bag diameters and lengths up to 8 m can be evaluated for project-specific designs. Such sizes are outside the standard table and require confirmation of the collector layout, cleaning system and installation and replacement clearance.
05Quick Selection
Scale Up the 81-Bag Standard Module
For a quick preliminary estimate, use one 81-bag module with Ø155 × 3.0 m bags as the reference building block. Combine modules to increase the nominal filter area while checking the project layout and maintenance clearances.
1 module · 81 bags · 118.3 m²Reference airflow: approximately 10,000 m³/h under the same assumed operating conditions (approximately 1.41 m/min based on nominal bag area).

| 10 | 810 | 1,183.3 m² | 100,000 m³/h |
Airflow figures are proportional reference values for a preliminary comparison, not fixed ratings. Select filter media and design filtration velocity for the actual dust and operating conditions before confirming the effective area, module count, fan and final airflow. The ten rows are examples and do not define a maximum number of modules.

07Applications
Round Baghouse Applications
Modular round baghouses can be configured for a range of industrial dust and process exhaust streams. Filter media, air-to-cloth ratio and equipment details are selected for the actual operating conditions.
Steel and Metallurgy
Collect particulate from selected metal production and material handling points, with inlet conditions reviewed for each process.
Boilers and Biomass
For suitable boiler exhaust streams, specify the filtration system around the measured inlet temperature, fuel ash and moisture.
Industrial Kilns
Filter particulate from suitable kiln-related exhaust after checking temperature peaks, gas composition and upstream treatment.
Calcium Carbonate & Cement
Collect fine dust from calcium carbonate grinding, classifying and conveying, as well as suitable cement and mineral handling points.
Chemical Powders
Match bag media and construction to the powder properties, process gas and any required corrosion or static control.
Woodworking
Collect wood dust at suitable extraction points, with fire and explosion protection assessed for the specific process.
Ore Crushing & Coal Conveying
Collect dust at ore crushing and coal belt conveyor transfer points, with filtration and safety measures selected for each material and process.
Application examples are not fixed equipment ratings. Confirm dust characteristics, temperature range, humidity, gas composition and required safety measures before selecting filter media, filtration velocity and module count.
