Furon® Valve Box Enclosure is designed for flow-through ventilation and pressure containment applications, due to its 5 psig pressure rating. A Type II PVC material and twin-sheet thermoform design allows for valve and connection inspection. Valve box measures 24 × 24 inches, providing input/output connections on four sides. Leaks are avoided through the molded seamless construction and Viton® seal.

Model 012 is a fractional horsepower oil-less air compressor designed specifically as a component for manufacturers of aerosol nebulizers. In this application, the compressor pushes air through a jar of medication, atomizing the medication into very small particles so that it can be easily inhaled into the lungs of the patient for effective treatment of asthma. Other design features include: reduction in the number of ball bearings from three to one; use of plastic components that are injection molded in house versus die-cast zinc that comes from an outside supplier; and a snap-fit assembly instead of screws.

The X Systems™ is a durable thermoelastomer assembly, eliminating seals and screws for the valve to manifold interface. The design is said to allow for standard and complex pneumatic manifold circuitry, including multiple-operating pressures, vacuum, or partitioned configurations. Advantages over traditional aluminum manifolds reportedly include lower cost, lighter weight, and rapid prototyping.

The Minimatic Air Regulator-1 (MAR-1) features a downward and upward adjustable pressure, with range springs of 0-100 psi. According to the company, pressure is held constant while avoiding downstream pressure creepage. No tools are required to choose pressure from the 40 pitch threads with the knurled micro adjustment knob. Air regulators are designed for panel mounting, particularly in control circuits or on individual jigs or fixtures.
