The "Series DH3" differential pressure controller provides a 4–20 mA process output, two single-pole double-throw relays with adjustable dead bands, and a large, bright backlit LCD display. The DH3 offers simplified programming via a menu key that enables the user to select: security level; set point or set point and alarm operation; auto or manual alarm reset; English or metric engineering units; pressure, velocity or flow operation, K-factor for use with various Pitot tubes and flow sensors, circular or rectangular duct size for volumetric flow operation plus many more. The sensing element can detect low differential pressures down to 0.1 in. w.c. Ranges up to 100-in. w.c. as well as bidirectional ranges are also available. These features make the DH3 "Digihelic" differential pressure controller the ideal instrument for monitoring pressures in various rooms, zones, and ducts in factories, laboratories or buildings.

Smith: We will be introducing a new positive pump specifically for the pharmaceutical industry. Our "Johnson Top Wing" pump uses innovative materials, an extremely simple, clean internal design and several gearbox innovations to address industry concerns about efficiency, reliability, and the ability to clean-in-place and steam-in-place.

Water purification and disinfection

For filtration, we are introducing a tangential-flow hollow-fiber filter that can be used in processing various solutions in pharmaceutical manufacturing. The most common use would be to filter fermentation broths in biotech processing. The advantage is faster processing times with higher yields.

For disinfectants, we are introducing a "Mini Fog" device for dry fogging small enclosures such as hoods in laboratories. This will replace a very labor-intensive and inefficient process of manually cleaning these areas with a process that is fast and very effective.

Personal protection equipment

Rowe: In 2008, Bullard will be launching and promoting our sterilized respirators that are FDA-validated to 10^-6 sterility-assurance levels.
