Portable Exhaust Extractor for Trucks & Heavy Equipment | DPF & Carbon Filtration System
Product Introduction
The Fengshen Portable Exhaust Extractor is a heavy-duty, mobile filtration unit engineered for the unique challenges of servicing large vehicles with vertical or under-chassis exhaust systems. Designed for trucks, buses, agricultural and construction machinery, fire engines, military vehicles, and more, this system provides a vital solution where fixed infrastructure like an overhead Sliding Rail Trolley is impractical or cannot reach. It is a compact, self-contained unit that captures toxic diesel exhaust at the source, purifying it through an advanced DPF (Diesel Particulate Filter) and Activated Carbon filtration system before release. This makes it indispensable for workshops, depots, and fire stations that maintain large fleets.
Features & Characteristics
-
Heavy-Duty Mobility with Braked Casters: Equipped with four swivel casters (two with brakes), this portable exhaust extractor can be effortlessly maneuvered around the workshop and positioned securely next to large vehicles, offering freedom that a fixed Sliding Rail Trolley system cannot provide for non-standard parking.
-
Advanced DPF & Carbon Filtration: The core purification combines a Diesel Particulate Filter (DPF) to capture over 99% of harmful soot particles, followed by an Activated Carbon bed to adsorb toxic gases and odors. This dual-stage process ensures thorough treatment of diesel emissions.
-
Fully Adjustable Capture Arms for Versatility: Features a telescoping vertical mast (1350-3200mm) and a telescoping, swing-away horizontal arm (950-1350mm). This allows the capture hood to be easily positioned over tall vertical stacks or stretched out to reach under-chassis exhaust pipes, solving the access limitations of a standard Sliding Rail Trolley hose.
-
Self-Contained for Any Location: As a complete, portable exhaust system, it requires no permanent installation or ducting. It is the ideal solution for temporary work areas, field service, or facilities where installing a Sliding Rail Trolley network is cost-prohibitive or structurally impossible.
-
Robust Design for Industrial Environments: Built to withstand the demanding conditions of heavy equipment repair, ensuring reliable performance when capturing high-temperature, high-volume exhaust from large diesel engines.
Why Choose Us?
We specialize in providing targeted air quality solutions for the global heavy vehicle and equipment sector. We understand that a one-size-fits-all approach doesn't work; while a Sliding Rail Trolley is perfect for standardized auto bays, our portable DPF extractor solves the critical problem of servicing oversized and uniquely configured vehicles. Our products are engineered for reliability and performance, serving professionals in the UK, Australia, Canada, the USA, Malta, the Netherlands, Denmark, Norway, Germany, Switzerland, and over 60 countries. We deliver the specialized equipment needed to ensure safety and compliance in any workshop environment.

Frequently Asked Questions (FAQ)
Q: How is this different from a standard workshop Sliding Rail Trolley system?
A: A Sliding Rail Trolley is a fixed, overhead system designed for passenger cars in defined bays. This portable extractor is mobile, has articulating arms to reach high or recessed exhaust pipes, and includes advanced DPF/carbon filtration for heavy diesel exhaust. It is designed for vehicles that a standard Sliding Rail Trolley cannot physically accommodate.
Q: How do I maintain the DPF filter in this unit?
A: The Diesel Particulate Filter (DPF) captures soot and requires periodic regeneration (a high-temperature burn-off cycle) to clean itself. The unit will typically indicate when this process is needed. This is specific to deep particulate filtration and differs from maintaining the fan in a Sliding Rail Trolley system.
Q: Is this unit powerful enough for large diesel fire truck engines?
A: Absolutely. It is specifically engineered for high-capacity diesel applications. The filtration system and motor are sized to handle the substantial exhaust volume from fire apparatus, industrial engines, and other large vehicles during maintenance and testing procedures.
Q: Can it be used outdoors or in field service situations?
A: Yes, its fully self-contained and mobile design makes it perfect for field service, temporary repair sites, or outdoor maintenance yards where a permanent Sliding Rail Trolley is not an option. It provides critical fume control anywhere power is available.
Q: Why is the adjustable arm system so important?
A: The telescoping and swinging arms are crucial for operational flexibility. They allow a single operator to quickly and safely connect the unit to exhaust pipes located at various heights and positions, which is a common challenge when servicing diverse heavy equipment that cannot be serviced under a standard Sliding Rail Trolley.
