Product Description

Product Description

Low-Pressure Drop Self-Cleaning Air Filters for Centrifugal Air Compressors
  
The self-cleaning air filter is a high-efficiency filtration system featuring automatic dust-cleaning functionality. It delivers exceptional filtration efficiency of up to 99.99%, requires minimal footprint, and offers extended filter element lifespan. Equipped with an automatic alarm system, it operates with zero routine maintenance and enables filter element replacement without system downtime. With low operating costs, this filter is widely applicable across industries requiring stringent control of airborne particulate levels, including compressor stations, steel plants, and pollution control systems in the chemical fiber and textile sectors


Application Scope:

1. Multi-unit sharing/Individual installations: Precise description of configuration flexibility

2. Induced draft fans: Technical term for blast furnace ventilation equipment

3. Raw material air compressors: Standard term in ASU (Air Separation Unit) processes

4. Intake ports: Preferred over "air inlets" for turbines/engines

5. Particulate contaminants: Technically accurate beyond "impurities"

6. HVAC air supply systems: Industry-standard terminology

7. Stringent particulate control: Professional phrasing for air quality requirements

8. Deployed: Strategic verb implying purposeful industrial application

Filtration process:
Under the negative pressure of the compressor, the surrounding air is inhaled. When the air passes through the high-efficiency filter cartridge, the dust is retained on the surface of the filter cartridge due to gravity, static electricity and contact, and the purified air enters the clean air chamber and then flows out through the air outlet pipe.

Self-cleaning process: When the computer issues an instruction, the solenoid valve starts and drives the diaphragm valve, instantly releasing a pulse airflow with a pressure of 0.4-0.6MPa, which is rectified and sprayed out through a special nozzle. The Venturi tube rolls, seals, and expands from the inner depth of the filter cartridge to the outside, evenly impacting the dust accumulated on the outer surface of the filter cartridge, and the self-cleaning process is completed.

FAQ

Q: What is the actual filtration efficiency of this filter?
A: Our filters achieve >99.99% efficiency on particles ≥0.5μm (tested per ISO 16890 ePM1 standard), critical for turbine/compressor protection.

Q: Can filter elements be replaced without shutting down equipment?
A: Yes. Zero-downtime cartridge replacement is enabled by our patented modular design, ensuring continuous operation.

Q: What's the typical lifespan of filter elements?
A: Element life ranges 12-36 months depending on environment. Our auto-alarm system triggers when replacement is needed (at 250Pa final resistance).

Q: How much energy does the automatic blowback consume?
A: Pulse-jet cleaning uses <0.8m³/min compressed air at 0.6MPa, with <0.1% total system energy consumption.

Q: Is this filter suitable for hazardous environments?
A: We offer ATEX/IECEx-certified models (Zone 1/21) with explosion-proof housings for chemical/oil & gas applications.

Q: What maintenance is required?
A: True zero routine maintenance. Only annual control cabinet checks and element replacement every 1-3 years.

Q: Can it handle high-humidity or freezing conditions?
A: Yes. Models feature heated drain traps (-40°C to 80°C operating range) and moisture-separation baffles for humid/arctic sites.

Q: How much space does the system require?
A: Compact vertical design with 40% smaller footprint vs. traditional filters (e.g., 2000m³/min unit fits in 2m²).

Q: What industries do you specialize in?
A: We serve O&G compressor stations, steel mill blast furnaces, ASU plants, power generation turbines, and pharma HVAC systems.

Q: How do I calculate cost savings?
A: Our filters reduce energy costs by 15-30% (via low 80-150Pa initial resistance) and eliminate maintenance labor. Request a ROI analysis for your site.
