ControlAir is a worldwide leading manufacturer of precision pneumatic and electro pneumatic control products essential to automated industrial equipment, process control systems and instrumentation, laboratory research and analysis, energy management, fluid power, robotics, and valve automation applications. An ISO-9001 registered quality system assures tightly controlled specifications and processes, resulting in high performance, dependable pneumatic controls.

The company has an excellent reputation for high performance, quality products. These products include current-to-pressure (I/P) transducers, voltage-to-pressure (E/P)transducers, pneumatic-to-current (P/I) transducers, precision air pressure regulators, filter regulators, volume boosters, motorized regulators, rolling diaphragm air cylinders and custom engineered devices. ControlAir distinguishes itself from competitors in the unique ability to adapt its products to customer-specific applications through joint development projects and strategic design partnerships. 

Founded in 1987, ControlAir is a closely-held, privately owned company whose stockholders include key management personnel. Dedicated effort, in combination with vast knowledge of pneumatic controls technology and its markets, has provided ControlAir with consistant sales growth over the history of the company. Continual investment in research and development has been made in order to produce a steady stream of new products that will fuel future growth. Development of a world wide distribution network has led to an active, international presence on every continent from North and South America to Europe and the Far East. Over 15% of ControlAir's sales are outside the U.S. 

In October of 1997 significant manufacturing capacity was added when ControlAir opened its new headquarters located in a 26,500 square foot engineering and production facility in Amherst, New Hampshire. The new building features a technology/application center; offering ControlAir's customers newly-expanded CAD/CAM product design capabilities for quick response to demands for product customization to fit specific application needs. 

More recently, in December of 2002, ControlAir acquired the Dahl Electronics product line from Purolator Facet, Inc., formerly known as the G.W. Dahl Co., Inc.. Products included in the purchase were P/I Transmitters (pressure to current), I/P Converters (current to pressure), Snap-acting Pneumatic Relay's and Liquid Level Indication Systems. Manufacturing of the product line was transferred to ControlAir's headquarters in Amherst, New Hampshire. ControlAir offers the product line under the Dahl Products Group heading.

In December of 2003, ControlAir successfully completed an ISO 9001-2000 transition audit allowing the Company to maintain registration as an ISO 9001 certified company.

ControlAir's customer-driven, "flat" management structure minimizes corporate overhead and staff, allowing the company to be very price competitive. In addition, its automated inventory control operation minimizes inventory, while assuring customers of in-stock availability and on-time delivery. 

The company's capability to manufacture products to tightly controlled specifications and processes allows ControlAir to offer solutions with higher performance standards, increased dependability and tighter quality standards than might be found elsewhere in the market.
