Diesel particulate filters
for data centers, hospitals, fleets, marine and more
Rypos active DPF systems help you reduce diesel particulate emissions, meet EPA Tier 4, CARB Level 3+ and regional AQMD requirements, and keep critical engines running reliably. They capture up to 95% of diesel particulate matter and regenerate electrically at any load, so operations stay compliant without the downtime, clogging or added cost of passive filters.
Regulatory confidence
New emissions standards are forcing diesel asset owners to act. Rypos Active DPF emission control systems are independently verified to meet EPA Tier 4 levels, CARB Level 3+ standards and the toughest regional mandates, from South Coast to Bay Area AQMD without unnecessary equipment replacement, downtime or operational disruption. Install once and operate without fear of fines, runtime limits or failed inspections.

Why Organizations Choose Rypos
Hundreds of hospitals, data centers, utilities, ports and TRU fleets rely on Rypos active DPFs to keep engines compliant, reliable and cost-efficient. Unlike passive filters, which depend on sustained high exhaust temperatures to burn off trapped soot, Rypos systems use electric self-regeneration that works at any load, including low-load and standby conditions. Each system is engineered for its specific application and backed by a team that has spent over two decades refining diesel emissions control.
Why Rypos DPFs?
- Regulatory compliance: Meets or exceeds EPA Tier 4, CARB Level 3+ and district air-quality requirements.
- Reliable by design: Electric self-regeneration prevents clogging at any load or runtime.
- Low lifecycle cost: Self-cleaning operation minimizes service calls and total cost of ownership.

Integrated Emissions Control for Tier 4 Compliance
Meeting EPA Tier 4 requirements means addressing NOx, PM, and gaseous emissions in concert. Rypos combines active DPF technology with Selective Catalytic Reduction (SCR) in a single engineered solution, available in integrated or separate component housings to fit new installations and retrofit applications alike.
Key Features
- Reduces NOx, PM, CO, VOC, and NO₂
- Integrated diesel oxidation catalyst (DOC)
- Low-profile housing with sound attenuation up to Super Critical Grade
