What Air Logic does
Air Logic, a division of Knapp Mfg., Inc., designs and manufactures miniature precision fluid control components for OEM devices. Founded in 1975 when Knapp acquired the Fluidic Division of Johnson Controls, the company operates from Racine, Wisconsin, with a workforce of 51-100 employees. Its product portfolio spans flow restrictors (orifice restrictors, needle valves, directional flow valves), miniature plastic filters, check valves (umbrella, floating disk, spring-loaded ball), tube fittings, relief valves, regulators, and pressure/vacuum switches — sold as standard catalog items or customized through orifice sizing, fitting sizing, factory presets, product combinations, and custom plastic molding across 12+ material chemistries.
The company produces components via 23 in-house injection molding presses (27-240 ton clamping force), a dedicated tool room, and 20kHz/40kHz ultrasonic welding for hermetic assembly. Precision is a core technical attribute: molded orifices deliver +/-4% flow tolerance across a Cv range of 0.00038 to 0.04, and proprietary umbrella check valves crack below 2 psi. The business sells through a dual channel — direct e-commerce for small US orders (under 100 units) and a worldwide distributor network for OEM volume accounts — supplemented by content marketing (flow calculator, technical blog, YouTube) and free sample kits. Custom product work typically requires 5,000+ EAU for custom materials or 20,000+ for tooling, and the company also offers third-party contract manufacturing leveraging its molding and assembly capacity. Vertical customers include medical devices (e.g., Ford Motor Company ventilator components during COVID-19, ~11 parts per unit), microfluidics (Bartels Mikrotechnik, Flow Circuits), analytical instruments, and consumer products; ISO 9001:2015 certification and Assent-mediated compliance monitoring (REACH, RoHS, MDR, PFAS, Conflict Minerals) support regulated end markets. Ownership is concentrated among three employees who bought out the Knapp family in 1993; no external capital or public listing exists.

Air Logic product offering
Product offeringCore offering
Air Logic designs and manufactures miniature fluid control components, including flow restrictors, filters, check valves, tube fittings, relief valves, regulators, and pressure/vacuum switches, for OEM devices in pneumatic, fluidic, and vacuum applications. The company sells both standard catalog components via e-commerce and distributor networks, and offers custom manufacturing services including orifice sizing, fitting sizing, factory presets, product combinations, and custom injection molding. Contract manufacturing and design support are provided through vertical integration with parent Knapp Mfg., Inc.
Product overview
Air Logic is a manufacturer of miniature fluid control components for OEM devices, offering a broad portfolio of precision-engineered pneumatic and vacuum control equipment. The core product line centers on Flow Restrictors (orifice restrictors, filtered orifices, directional flow control valves, threaded orifices, and needle valves), Miniature Plastic Filters (barbed inline, threaded inline, intake), Check Valves (umbrella, floating disk, spring-loaded ball types), Tube Fittings (swivel, bulkhead, static), Relief Valves, Regulators (R-4000, NR-4000, R-7000 series), and Switches (pressure and vacuum). These components are sold as standard catalog items and can be customized through orifice sizing, fitting sizing, factory presets, product combinations, and custom plastic molding services. The company also provides contract manufacturing capabilities including injection molding, assembly, ultrasonic welding, and packaging.

Products and services
- Miniature Flow Restrictors A comprehensive line of flow control components including orifice restrictors, filtered orifice restrictors, directional flow control valves, threaded orifices, and needle valves (both metal and plastic) that control flow rates of gas or liquids through OEM devices.
- Miniature Plastic Filters Compact plastic filters including barbed inline filters, barb-to-thread filtered adaptors, threaded inline filters, and intake filters that protect sensitive components from debris and contamination in fluid systems.
- Miniature Check Valves Miniature plastic check valves including umbrella check valves, floating disk check valves, threaded floating disk check valves, normally closed check valves, and spring-loaded ball check valves that prevent backflow and facilitate forward flow in pneumatic and fluid circuits.
- Tube Fittings Miniature tube fittings including swivel fittings, bulkhead fittings, static fittings, and swivel bulkhead fittings for connecting tubing in fluid systems.
- Relief Valves Adjustable relief valves that open the input port to the exhaust port when a specific pressure differential is achieved, protecting systems from overpressure conditions.
- Regulators Precision pressure regulators including R-4000 Relieving Regulator, NR-4000 Series Non-Relieving Regulator, and R-7000 Series Precision Pressure Regulator for accurate pressure regulation with minimal consumption.
- Switches Subminiature pressure switches and vacuum switches including F-5100 Series Pressure Switch and V-5100 Series Vacuum Switch that change electrical state based on pressure signals.
