Self-cleaning Filter

Automatic Cleaning for Clear Centrifugal-compressor Intake Airflow

Self-cleaning filters automatically remove surface dust to help maintain airflow where dust loading needs control. Match airflow, dust characteristics and cleaning requirements. Filter media and seals still need regular inspection.

Designed for centrifugal-compressor intake systems, the filter combines dust capture, differential-pressure monitoring and automatic reverse-pulse cleaning to limit dust-related intake resistance. Match the configuration to airflow, connections and site conditions across different compressor makes.

Filtration, Cleaning and Maintenance in One Design

Capture Dust and Protect Core Components

Filter media capture solid particles in intake air, reducing the risk of dust reaching impellers and internal precision components. Select media for particle size and intake requirements; filtration rating and efficiency depend on the confirmed configuration.

Automatic Reverse-pulse Dust Removal

Reverse cleaning airflow releases dust from the filter surface into the collection chamber. During normal filtration, programmed online cleaning reduces frequent manual cleaning. Servicing and element replacement still require safe shutdown and isolation.

Manage Differential Pressure and Maintain Airflow

Monitor differential pressure across the elements and remove accumulated dust to help control intake resistance. Confirm initial pressure drop, cleaning thresholds and maximum allowable resistance for the selected media and airflow.

Robust Enclosure for Site Integration

The enclosure, supports and connections provide a stable installation with service access. Confirm materials, protective finishes and inlet/outlet connections for indoor or outdoor location, humidity and corrosive conditions.

Modular Maintenance and Convenient Inspection

Select self-cleaning filtration around airflow, dust characteristics and cleaning conditions, including installation space and maintenance access. Automatic cleaning helps manage dust buildup, but filter media, seals and cleaning equipment still require checks. Contact sales for configuration and replacement media, with details of site dust and equipment operation.

Five Steps from Filtration to Automatic Cleaning

The diagram illustrates filtration and cleaning. Confirm cleaning-air supply, valves and controls for the supplied configuration.

1. Dust-laden Air Enters

   Air enters the filter and follows the inlet flow arrangement.

2. Particle Pre-separation

   Where a swirl pre-separator is fitted, larger particles fall into the collection chamber first.

3. Filter-element Filtration

   Air passes through the media, particles are retained and filtered air reaches the compressor intake.

4. Automatic Reverse-pulse Cleaning

   As dust raises differential pressure, the controller initiates reverse-pulse cleaning according to its settings.

5. Dust Collection and Discharge

   Released dust collects in the chamber for discharge and routine removal.

Match Intake Demand, Not Just Connection Size

Before matching different centrifugal-compressor makes, check intake airflow, allowable pressure drop and installation conditions. Provide the compressor model, inlet drawing and site dust conditions to determine the elements, enclosure and cleaning controls.

Confirm model, airflow, filtration rating, pressure drop and dimensions in the selection proposal. This intake dust filter does not replace dryers or precision filters in the compressed-air distribution system.
