M600 RFOS™

Rotary-Wing Fuel Handling Without the Hassle

Built for Helicopters. Engineered for Speed & Safety.

Refueling and defueling helicopters shouldn’t slow down operations. Towing fuel trucks into tight spaces, relying on outdated bucket-and-hose methods, and dealing with contamination risks all waste time and increase safety hazards.

The M600 RFOS (Rotary Fueling Operations System) eliminates these problems with fast, controlled fuel transfer, integrated filtration, and a compact, mobile design.

Designed for military and civilian rotary-wing aircraft, the M600 RFOS is the smarter way to fuel and defuel UH-60, AH-64, CH-47, and other mission-critical platforms. Used by the U.S. Military, Law Enforcement, Firefighting Agencies, and Helicopter Operators Worldwide.

The Hidden Costs of Standard Helicopter Fuel Handling

If your fueling process involves excess transport, manual handling, or slow transfer rates, here’s what it’s really costing you:

Slow Turnaround: Gravity-fed fueling and manual defueling waste time.
Fuel Contamination: Open-air fuel handling increases the risk of water and particulate contamination.
Safety Risks: Spills, vapor exposure, and static discharge create avoidable hazards.
Unnecessary Wear on Equipment: Repeated towing of helicopters and fuel trucks leads to more maintenance costs.

A major U.S. military base reduced helicopter fuel servicing time by 50% using the M600 RFOS.

That means faster refueling, quicker turnaround, and improved operational readiness.

More Than a Fuel Cart—An Operational Advantage

The M600 RFOS isn’t just a fueling system. It’s an investment in faster operations, safer fuel handling, and greater mission flexibility.

Faster Refueling & Defueling: Reduces downtime and gets aircraft back in the air faster.
Fuel Recovery & Reuse: Integrated filtration prevents fuel waste and ensures clean, aviation-grade fuel.
Safer Ground Operations: Sealed fueling system eliminates spills and vapor exposure.

More efficiency, less waste, and better aircraft availability.

What Our Customers Are Saying

“We went from a fuel sumping taking 14 hours on an Airbus A330, to just two hours once we converted our process to the SealVac bowser”

—

Delta Airlines Maintenance Base DTW (formerly Northwest Airlines), Detroit, MI, USA

“[On RAAF C130 aircraft, the SealVac] significantly reduces the time taken to vent the tanks from three days to just two hours from tank opening”

—

RAAF C130 Base Richmond, Hawkesbury, NSW, Australia

“The messy job of repairing fuel cells and tanks has also been improved with the purchase of a SealVac bowser. No fuel spills equate to more recovered fuel, fewer spill pads, and less hazardous waste. Preventing spills also eliminates the associated health exposure”

—

2007 Secretary of Defense Environmental Award, Fairchild AFB, WA, USA

“[Using the SealVac], we spend 2 hours power pumping a 747. If we did the job manually, it would take about 6 hours”

—

United Airlines Maintenance Base SFO, San Francisco, CA, USA

“We just received our 600 gallon HandiFueler Refueler / Defueler last December. It is an outstanding piece of equipment; very well made and thought out. We couldn’t be happier.”

—

Iowa ANG

“We just received the HandiFueler AGE Service Cart at my base in Southwest Asia; already everyone loves it, especially compared to the patched together carts we were using. Thank you for making our jobs easier.”

—

An Airbase in Southwest Asia

“We’ve had our HandiFueler for a couple of years now. It is absolutely the best investment. My guys save so much time and hassle servicing equipment… it is absolutely the best for our needs.”

—

Joint Base Pearl Harbor – Hickam

“[Using SealVac], the time saved on the [C-130J] external tank drain procedure is 20+ hours”

—

USCG Station Elizabeth City, Elizabeth City, NC, USA

“On average, [by using the SealVac] the company would decrease time spent waiting on fuel to drain by 4 times, allowing the technicians to work on the aircraft much faster”

—

Jet Aviation St Louis, St Louis, MO, USA

“The time necessary to defuel has been cut dramatically using the HeliFueler [M600 RFOS]. We have found it to be exceptionally useful. For defueling and sumping, the HeliFueler is our first choice, by far.”
