RAMFAN Wing Tank Vent Cart: The Aircraft MRO Ventilation System That Could Save Your Crew’s Lives

Every year, aviation maintenance workers are hospitalized—or worse—from exposure to toxic fumes inside aircraft fuel tanks. The culprit? Inadequate ventilation during MRO operations. Here’s why the RAMFAN EB7325-WT is changing the game.

Working inside an aircraft fuel tank is one of the most hazardous jobs in aviation maintenance. The confined space. The residual fuel vapors. The toxic fumes from sealants, adhesives, and cleaning chemicals. One mistake with ventilation and you’re dealing with a medical emergency—or an explosion.

Traditional ventilation setups are a nightmare. Cables everywhere. Multiple power sources to manage. Equipment that wasn’t designed for hazardous atmospheres. And every extra piece of equipment on the hangar floor is another tripping hazard, another point of failure, another thing that can go wrong when lives are on the line.

Why the RAMFAN Wing Tank Vent Cart Changes Aircraft Fuel Tank Ventilation

The RAMFAN EB7325-WT Wing Tank Vent Cart isn’t just another piece of equipment. It’s a complete, purpose-built system engineered specifically for aerospace ground crews performing Maintenance, Repair, and Overhaul operations.

Everything you need—ventilation, lighting, power distribution—on a single mobile cart. IECEx-certified for explosive atmospheres. Ready to deploy in minutes instead of hours.

IECEx-Certified Components for Hazardous Aircraft MRO Environments

Here’s what separates professional-grade equipment from everything else: certification for use in explosive atmospheres. The EB7325-WT’s EFi75xx ventilator carries whole-unit IECEx/ATEX certification. That’s not just a sticker—it’s verification that every component has been tested and approved for use where fuel vapors are present.

As detailed in this article about enhancing aircraft safety with the RAMFAN Wing Tank Vent Cart, this certification isn’t optional when working in Class I Division 1 environments. It’s the difference between a safe operation and a potential disaster.

Complete Wing Tank Ventilation System Specifications

The EB7325-WT comes factory-mounted, palletized, and ready for worldwide deployment. Here’s what you’re getting:

Duct System for Aircraft Fuel Tank Ventilation

The included 12″ x 8″ x 8″ wye duct splitter enables simultaneous ventilation of both wings—or single-wing operation when needed. The system includes:

• Four 8″ diameter x 25′ conductive black ducts
• One 12″ diameter x 15′ conductive black duct
• One 12″ diameter x 100′ anti-static disposable duct
• Stainless steel 12″ duct couplers and plastic 8″ couplers
• Two vent-to-wing-tank adapters

Integrated Lighting for Aircraft MRO Inspection

Fuel tank inspection requires proper lighting—but that lighting must also be safe for hazardous atmospheres. The EB7325-WT includes:

All lighting connects through the central power distribution box, eliminating the cable clutter that creates tripping hazards and operational inefficiency.

Safety Features Built Into Every Wing Tank Vent Cart

Beyond explosion-proof certification, the EB7325-WT incorporates multiple safety features:

• Automatic braking system — Prevents rolling when unattended
• Adjustable mounting straps — Secure all equipment during operation and transport
• Integrated tie-down straps — Extra security for the cart itself
• Single AC power source — Minimizes cables and tripping hazards
• Storage boxes — Organized storage for ducting, couplers, and adapters

Aircraft MRO Applications: Where the Wing Tank Vent Cart Excels

The EB7325-WT’s rugged design enables deployment across multiple aviation environments:

Beyond fuel tank ventilation, the system handles multiple maintenance tasks including extraction of toxic dust, fumes, aerosol and vapor contaminants. It can also function as a mobile cabin air filtration or ventilation system.
