Two-Stage Filters – Medium / Heavy Dust
Our two-stage dry air cleaners deliver maximum engine protection and long-lasting performance in harsh, dust-laden environments. Designed for compact equipment through to heavy-duty machinery, these filters combine high dust-holding capacity, low restriction, and extended service life — ensuring reliable operation even under the toughest conditions. All filters are tested according to ISO 5011 to ensure consistent and reliable performance.Typical Applications
- Combustion engines
- Construction & mining machinery
- Agricultural vehicles
- On-/off-road trucks and buses
- Marine engines
- Generator sets
- Compressors and pumps
- Industrial/commercial vacuum systems
- Industrial systems (blasting, painting, welding)
- Plastic conveying or processing machinery
Two-Stage Air Cleaners – How They Work
Two-stage air cleaners maintain stable airflow and consistent filtration through a two-step process:- Stage 1 – Pre-Cleaner: Removes up to 85% of coarse dust, debris, and moisture before air reaches the main element. This reduces filter loading and increases service intervals.
- Stage 2 – Main Filter (with optional safety element): Captures fine particles for high-efficiency final filtration. A secondary safety element ensures continued engine protection during filter change or accidental damage.
- Dust Management: Depending on the model, dust is expelled via a discharge valve, collected in a reservoir, or continuously removed via an optional scavenging system. This compact two-stage architecture improves pressure stability and reduces maintenance.
