Low-noise blower
 |
The precision-balanced TCD Blower air-moving package features high performance and smoothness by combining the efficiency of the TEK backward-curved airfoil wheel with high-efficiency NEMA frame motors. According to the manufacturer, the blower meets AMCA 'B' spark-resistant requirements and is suited to applications that require low noise and high efficiency. The BCA impeller is manufactured of glass-reinforced polyamide. The steel scroll housing has an epoxy coating.

Dry chemical filters
 |
The Purafilter-CG and the Purafilter-FFU use a patented dry-chemical media to target specific groups of gases in specific areas of cleanrooms. The Purafilter-CG works in recirculation air applications, and the Purafilter-FFU can be incorporated into most FFUs upstream of HEPA/ULPA filters. Three media types are available for each filter: CPS for hydrogen sulfide, sulfur dioxide, organics and ozone; PSAM for acids, amines, ammonia and NMP; and PSPB for arsine, boron trifluoride, chlorine, hydrogen chloride, hydrogen fluoride, hydrogen sulfide and phosphine. Both filters are available with an integral 95 percent particle filter.

Ionizer controller
The Series 3300 ionizer controller controls either a multi-fan ionizer (two- or three-fan) or multiple single-fan ionizers. The product offers data output as a standard feature to report any alarm condition to the Series 6000 or Series 400 workstation/process equipment monitoring instruments. The product can be powered either by the ionizer to which it is interfaced, or with an optional external power supply.

Disposable filter
Designed with an improved membrane-pleating method, QuickChange ATM reportedly provides 40 percent improvement in membrane surface area compared to QuickChange ATX filters, leading to a higher flow rate that aids in the recirculation and recovery of a bath. The non-dewetting membrane technology delivers retention at 0.03 mm and withstands high-temperature applications (up to 180° C). Shipped water-wet, the products also reduce filter change-out time, minimizing system downtime.

Cartridge, PES filters
 |
The Multilayer Durapore 0.45-µm/0.22-µm cartridge filters are intended for pharmaceutical and biological liquid applications requiring high protein recovery and extended throughput. The multi-membrane construction provides a filter device with an integrated 0.45-µm prefilter membrane ahead of a final 0.22-µm sterilizing grade membrane for increased filtration capacity. The product is suitable for sterile filtration processes requiring high throughput, high product purity and high yield.
The high-flux sterilizing-grade polyethersulfone (PES) filter is used for the filtration of buffers, pH adjusters and other clean aqueous intermediate process solutions.
According to the manufacturer, the Express SHF (Sterilizing-grade High Flux) hydrophilic 0.2-µm filters provide superior flux, high sterility assurance and broad chemical compatibility with a range of buffer chemistries (pH 1-14), including acids and sodium hydroxide.

Modular conveyor
 |
Based on a building-block concept of high-impact, interchangeable plastic modules, accessories, and components, the ISO Class 3-approved DynaCon Modular Conveyor system provides cleanroom and associated controlled environments with flexibility and ease of reconfiguration to improve production flow and rapidly modify production schemes. The system requires no lubrication and includes a maintenance-free, brushless DC motor that produces no motor emissions. Dust-free polypropylene rods are used as the hinge-pins for the conveyor belt.

Piping and fusion package
 |
The PFA FuseBond System features repeatable high-strength PFA welds, low-weld bead profile and documentation of all ..welding parameters. Ideally suited for high-purity chemical and abrasive slurry applications in the semiconductor market, the system is offered with pipe, fittings and a line of manual and pneumatically actuated valves in sizes from 1/4-inch through 2 inches. The system combines George Fischer's IR Plus Joining Technology with Saint-Gobain's Furon brand of PFA piping.
