Electromechanical products include human-machine interface hardware and software; industrial PCs; single and multi-axis stand-alone and bus-based controllers; rotary and linear servo motors; rotary and linear stepper motors; analog and digital stepper and servo drives; precision gearheads, ballscrew, belt, and linear motor driven positioning tables; electric rod-style and rodless cylinders; and gantry robots. The Seal Group manufactures sealing devices, including o-rings and o-seals; gaskets and packings, which insure leak-proof connections; electromagnetic interference shielding; and thermal management products. The Filtration Group manufactures filters, systems and instruments to monitor and to remove contaminants from fuel, air, oil, water and other fluids and gases, including hydraulic, lubrication and coolant filters; process, chemical and microfiltration filters; compressed air and gas purification filters; lube oil and fuel filters; fuel conditioning filters; fuel filters/water separators; cabin air filters; intake air filters; and nitrogen and hydrogen generators and condition monitoring devices. The Instrumentation Group manufactures high quality critical flow components for process instrumentation and ultra-high-purity applications, including fittings, valves, regulators and PTFE products.

Industrial Segment products include custom units which are engineered and produced to original equipment manufacturers' specifications for application to a particular end product and standard items. Both custom and standard products are also used in the replacement of original motion control system components. Industrial Segment products are marketed primarily through field sales employees and more than 8,600 independent distributors.

Aerospace Segment.

Principal products of the Company's Aerospace Segment are hydraulic, fuel and pneumatic systems and components used on commercial and military airframe and engine programs.

The Aerospace Segment offers complete hydraulic and primary flight control systems that include hydraulic, electrohydraulic and electromechanical components used for precise control of aircraft rudders, elevators, ailerons and other aerodynamic control surfaces and utility hydraulic components such as reservoirs, accumulators, selector valves, electrohydraulic servovalves, thrust-reverser actuators, engine-driven pumps, motor pumps, nosewheel steering systems, electromechanical actuators, engine controls and electronic controllers. The Aerospace Segment also designs and manufactures aircraft wheels and brakes for general aviation and military markets.

The Aerospace fuel product line includes complete fuel systems as well as components such as fuel transfer and pressurization controls; in-flight refueling systems; fuel pumps and valves; fuel measurement and management systems; center of gravity controls; engine fuel injection atomization nozzles, manifolds and augmentor controls; and electronic monitoring computers.

Pneumatic components include bleed air control systems, pressure regulators, low-pressure pneumatic controls, engine starter systems, engine bleed control and anti-ice systems, and electronic control and monitoring computers.

Aerospace Segment products are marketed by the Company's regional sales organization and are sold directly to manufacturers and end users.

Climate & Industrial Controls Segment.

The principal products of the Company's Climate & Industrial Controls Segment are refrigeration and air conditioning systems and components and fluid control process systems and components for use primarily in the mobile and stationary refrigeration and air conditioning industry.

The Climate & Industrial Controls Segment manufactures components and systems for use in industrial, residential, commercial, automotive and mobile air conditioning and refrigeration systems and other applications, including pressure regulators, solenoid valves, expansion valves, filter-dryers, gerotors and hose assemblies. The Climate & Industrial Controls Segment products are marketed primarily through field sales employees and independent distributors and wholesalers.

Other Segment.

The principal products of the Company's Other Segment are custom-engineered buildings which are designed and manufactured by Astron; and automotive chemical products and professional automotive service equipment that are developed by the Wynn's Specialty Chemical Group.

Astron's pre-engineered single and multi-story buildings serve as factories, warehouses, aircraft hangars, indoor athletic facilities, automobile showrooms, offices and supermarkets. Astron's custom-engineered buildings are marketed primarily through builder/dealers and field sales employees.

The Wynn's Specialty Chemical Group's product line includes professional chemical products, programs and equipment for automobile service technicians and automotive chemical products for consumers. Products are marketed primarily to consumers, automobile dealerships and other automotive service facilities and are distributed through a strong network of independent distributors as well as a direct sales force.
