Petrol Purification Carbon Diesel Exhaust Extraction Systems Automotive DPF Activated

The Fengshen Portable DPF & Activated Carbon Exhaust Extractor is a professional-grade, semi-automatic mobile purification system designed for the safe indoor operation of diesel and petrol engines. This advanced unit directly tackles the two primary components of harmful vehicle exhaust: solid particulate matter (soot) and toxic gases. By integrating a Diesel Particulate Filter (DPF) with an Activated Carbon stage, it captures soot and adsorbs harmful vapors, allowing for engine diagnostics, repairs, and warm-ups in workshops, fire stations, and private garages. It provides a critical mobile solution where a fixed Sliding Rail Trolley extraction system is not applicable or needs to be supplemented for specialized tasks.

• Dual-Stage Advanced Filtration: The core of the system combines a Diesel Particulate Filter (DPF) to physically trap over 99% of hazardous soot particles, followed by a high-capacity Activated Carbon bed to adsorb carbon monoxide (CO), hydrocarbons (HC), and odors, delivering superior air purification.

• Mobile & Maneuverable Design: Mounted on 4 heavy-duty casters (2 with brakes), this portable exhaust extractor offers complete freedom of movement. It can be wheeled directly to any vehicle—whether in a bay or a corner—overcoming the spatial limitations of a fixed Sliding Rail Trolley hose.

• Enables Indoor Engine Operation: This unit is specifically engineered to safely capture and purify exhaust at the tailpipe source, allowing diesel and petrol engines to run indoors for extended periods for maintenance, testing, or cold-weather warm-ups without polluting the workshop air.

• Self-Contained & Hose-Free Operation: Unlike a Sliding Rail Trolley system dependent on overhead ducting and long hoses, this is a compact, all-in-one solution. It eliminates hose management issues and provides instant deployment wherever needed.

• Rugged Industrial Build: Constructed to withstand high exhaust temperatures and the demanding environment of automotive workshops, ensuring long-term durability and reliability.

We are a specialist provider of engineered air quality solutions for the global automotive industry. We understand that a complete workshop requires both fixed infrastructure like a Sliding Rail Trolley for general bay extraction and specialized mobile tools for targeted applications. Our portable DPF extractor fills this niche with cutting-edge filtration technology. We support our clients with certified, high-performance equipment and serve key markets including the UK, Australia, Canada, the USA, Malta, the Netherlands, Denmark, Norway, Germany, Switzerland, and over 60 countries worldwide, ensuring you have the right tool for every air quality challenge.

Q: How does the DPF in this unit work compared to a standard filter?
A: The Diesel Particulate Filter (DPF) is a specialized wall-flow filter that physically traps microscopic soot particles (PM2.5/PM10) from exhaust gas. It is far more effective at capturing particulate matter than a standard dust filter, similar to the technology used in modern diesel vehicles themselves, ensuring cleaner output air.

Q: What is the advantage of having both DPF and Activated Carbon?
A: It provides complete purification. The DPF removes the visible black smoke and harmful particulates, while the Activated Carbon removes the colorless, odorless, and poisonous gases like Carbon Monoxide. This dual-stage approach addresses all major health hazards in engine exhaust, going beyond the simple extraction of a Sliding Rail Trolley.

Q: Can this portable unit handle the exhaust from a large fire truck engine?
A: Yes, it is engineered for heavy-duty applications. The capacity of the DPF and carbon bed is designed to handle high-volume exhaust flows from large diesel engines commonly found in fire apparatus, trucks, and machinery for a considerable period before maintenance is required.

Q: How do I maintain the DPF and Carbon filters?
A: The DPF will require periodic regeneration (burning off trapped soot at high temperature) or replacement based on usage. The activated carbon bed will need replacement once saturated. The unit typically includes indicators or pressure gauges to signal when service is needed. This maintenance is more specialized than servicing a fan in a Sliding Rail Trolley system.

Q: When should I use this instead of my workshop's Sliding Rail Trolley system?
A: Use this portable DPF extractor when you need to run an engine indoors for purposes other than simply moving a vehicle in/out of a bay. This includes engine diagnostics, ECU tuning, emissions checks, or prolonged repairs. For simple exhaust evacuation during quick service, your overhead Sliding Rail Trolley is more convenient. They are complementary tools for different tasks.
