Mathers pneumatic control systems sequence speed, clutch (and shaft brakes) to ensure the safest, shortest possible timing for each maneuver for high-performance workboats.

Mathers Pneumatic System Options

The current generation AD12 and AD14 systems are the latest evolution of Mathers Pneumatic Controls - the ultimate in pneumatics with decades of control system knowledge built into these systems! Both the AD12 and the AD14 offer options for any configuration you need.

Mathers control stations can command your choice of:

• Mechanical or pneumatic remote control

• Hydraulic or pneumatic clutches

• Mechanically or pneumatically operated governors

NOTE: Mathers Pneumatic Controls are also compact for easy retrofits and easily integrate with existing governors, remote controls and shaft brakes!

Which System is Right For You?

AD12 Pneumatic Propulsion Control System

For high-performance workboats with reverse reduction gears
and diesel engines in the 500 to 10,00 horsepower range. 

With the AD12 in action, these vessels not only perform better, but optimally. The system's reliable sequencing, timing and positioning not only ensure more efficient maneuvering but contribute to reduced clutch and gear load, reduced transmission maintenance and longer engine life.

The AD12 system features include:

• Neutral delay (clutches disengaged and speed at idle) that automatically adjusts its duration according to the vessels speed

• An adjustable speed interrupt following clutch shift

• A speed boost (small increase in idle RPM prior to clutch engagement) if needed to keep the engine from stalling under load

• Timing controlled with fixed orifices

• Timing for proper control of propeller shaft brakes

• Manifold-mounted components

AD14 Pneumatic Propulsion Control System

For vessels with diesel engines in the 700 horsepower, or less range. 

The AD14 shares many of the AD12 features but is specifically intended for vessels with diesel engines in the 700 horsepower or less range. Because these engines are smaller and quicker to respond to load changes, two ADS14 features are different than the AD12: The neutral delay is fixed, not proportional, and there is no speed boost.

A model of simplicity, the AD14 features a compact size and few components, all of which are manifold-mounted. AD14 is an ideal choice for retrofit project; it can be installed directly onto any existing pneumatic system and is an ideal timing mechanism for shaft brakes.

The AD14 system features include:

• Compact design (perfect for retrofits)

• Neutral Delay (fixed duration)

• An adjustable speed interrupt following clutch shift

• Timing controlled with fixed orifices

• Timing for proper control of propeller shaft brakes

• Manifold-mounted components

Here's what people have to say about
Mathers pneumatic controls . . .

"Almost all our boats have Mathers pneumatic propulsion control systems. They're trouble-free and easy to maintain.

We can install whatever operating parameters we need - like speed boost or time delay for shifting. Each one is built so we can maintain and repair it ourselves and Mathers has always been there for us to provide any specialty items we may need."

"I began selling Mathers pneumatic propulsion control systems in 1975. Mathers Controls have consistently been good for our market . . . in fact the best you can get.

Engine and shipyard people here in Singapore rely on us for a good relationship and good products. We provide the first and Mathers provides the second. I'm still in business today because of Mathers Controls."
