Laminar Flow Cabinets
Air Science, Fort Myers, FL, has released a series of high-efficiency laminar flow cabinets designed to protect equipment and other contents of the work zone from particulates, for applications sensitive to such contamination. The Purair horizontal cabinets are available in 2, 3, 4, 5, 6, and 8 ft widths in standard and extra-tall heights for general applications. The hoods are shipped fully assembled. The rear wall of vertical flow cabinets is perforated to reduce work surface turbulence by removing some of the airflow to the rear. Horizontal flow cabinets are designed with a lip on the rear of the work surface to protect the ULPA filter from spills. The high-capacity air-handling system delivers flow velocity of 0.35–0.45 m/s or 70–90 fpm.

Miniature Servo Motor Drive
Granite Devices, Tampere, Finland, has released a new industrial servo motor drive. A The 700-W IONI provides snap-on installation and built-in SIL2 safety functions in a 70 × 37 × 7 mm form factor. An improved high dynamic range torque control allows the motor drive to connect a range of motor variants to a single drive type. Through trajectory buffering and distributed clock synchronization, it can perform multi-axis synchronous motion control out of a non-real-time host, such as Windows PC with a USB or Ethernet connection. This has been achieved by the means of hardware side. The drive connects directly to the fully open C/C++/C# programmable SimpleMotion bus as well as traditional digital pulse train and analog controllers.

Photo-Etched Screens and Filters
Tech-Etch, Plymouth, MA, photo etches custom screens, filters, and filter supports for medical devices and other uses. Photo etching enables designers to specify a straight hole or a tapered hole, which facilitates liquid filtration and back flow cleaning. Hole sizes range from 0.003 in. up. Unlike stamping, photo etching yields a burr-free product, resulting in cleaner, more efficient screens with greater material integrity. Photo-etched screens feature a tighter tolerance on hole sizes and greater dimensional stability than woven wire mesh, making them ideal in applications requiring frequent cleaning or in devices where there is mechanical contact. Unlike woven wire mesh screens, the fixed photo-etched openings do not change through use. These tight tolerance screens are primarily produced from stainless steel, but other materials, including polyimide, are available.
