How do you improve on a great idea? With four significant changes over the FA2A, the FA2B takes a good idea and makes it even better. ■ Four changes for improved performance and reliability • NEW MP150 piston motor maintains the progressive scotch yoke and adds more horsepower (16 hp). Oil free design with fewer parts and reduced vibration means easier and less frequent service. Two other piston motor options are available. • New self-cleaning K5C2 control valve improves flow and performance. It has a primary bushing for reduced maintenance cost, more stainless steel and polymer corrosion resistant parts for smoother, more responsive control and is totally interchangeable with previous designs. 100% natural gas/sour gas compatible. • Modified gearbox design improves efficiency and durability. • Redesigned disc brake lowers required release pressure to 25 psig for smoother performance and no drag when air supplies are borderline. ■ What else is new.... • Lifting lugs • One size fastener on the entire motor. • Slide lift column on throttle prevents accidental movement.
