Self Cleaning Filters for Dust & Air Purification
Automatic Dust Removal for Continuous Air Purity
Manual cleaning of filters can lead to maintenance downtime, reduced system efficiency, and increased labor costs—especially in industrial air filtration, HVAC systems, or dust-prone environments. That’s why Trueair offers advanced self-cleaning filters that ensure continuous filtration while automatically removing accumulated dust and particles.
Designed with mechanisms like pulse-jet cleaning, mechanical shaking, or reverse airflow, our self-cleaning filters eliminate clogging and maintain peak airflow—without interrupting operations.
How Do Self-Cleaning Filters Work?
| Cleaning Method | Description |
| Reverse Air Flow | Blows air backward through the filter media to dislodge and remove accumulated dust and debris. |
| Pulse-Jet Compressed Air Cleaning | Uses short bursts of compressed air to shake off dust, commonly used in baghouse systems. |
| Rotary Scraper or Mechanical Agitators | Mechanically scrapes the filter surface to clear buildup without removing the filter. |
| Backflushing with Water or Air | Reverses fluid or air flow to wash away collected particles, ideal for liquid/air filtration. |
| Timed/Differential Pressure-Based Cleaning Cycles | Automated cleaning triggered by set time intervals or pressure drop across the filter. |

FAQs – Self Cleaning Filters
What’s the difference between manual and self-cleaning filters?
Manual filters need regular physical removal and cleaning. Self-cleaning filters automatically remove dust using air pulses or agitators, reducing downtime and labor.
Are these suitable for high dust environments like cement plants?
Absolutely. Trueair’s pulse-jet or rotary self-cleaning filters are engineered for dusty zones like cement, steel, and mineral processing.
How is the cleaning initiated?
Cleaning can be triggered via timers or when a pressure differential threshold is crossed, ensuring optimal performance.
Can self-cleaning filters be retrofitted to existing HVAC or duct systems?
Yes. We offer modular units and retrofit kits suitable for most commercial and industrial setups.
Do these require compressed air?
Only pulse-jet systems require compressed air. Other mechanisms use motorized scrapers or reverse airflow.
