Pneumatic Feeders
This line of pneumatic feeders is designed to meet the needs of feeding applications up to 8 tn/hr. Engineered for the rugged plant environment, the units feature durable, easy-to-clean, all-stainless-steel construction. This ensures compliance with the tight sanitary regulations specified by the food, chemical, and pharmaceutical industries. Pneumatic drive systems eliminate the hazards of sparks or heat, and run efficiently and quietly at 65 dBa. Less expensive than volumetric feeders, they can be set to deliver a constant feed rate or an exact amount for batch processes. Equipment is offered in a variety of sizes and models, including vibratory trays (VF-series), feeders with bin hoppers (VFBB-series), and feeders with conical hoppers (VFH-series). All units are covered by a three-year guarantee.

Wireless Baghouse Control System
The B-PAC G3 series baghouse diagnostic control system provides wireless communications through Modbus or Ethernet networking options. They can communicate with up to 32 B-PAC dust collector control systems with one base radio. Base radios connect to the company’s FilterWare HMI/SCADA/EPA compliance software and enable obtaining a wealth of process control, maintenance, and EPA MACT compliance information without installing costly network cabling. The wireless communications are ideal for cement, mining, iron, steel, and chemical plants. They can lower emissions, reduce energy use, and cut maintenance costs.

Mixer Extruder
The Model ME 1600 SL mixer extruder features stainless-steel construction, with heating jacket, vacuum cover, and 300-gal capacity. The unit is designed to intensively knead, mix, and disperse powders with liquids to manufacture high-viscosity products. The products are then extruded via the specially designed extrusion screw through a “spaghetti” die, and into a vacuum chamber for further processing. This mixer is used in the production of adhesives, sealants, caulks, putties, ceramics, and any other processes where highly viscous products are manufactured.

Bench Scales
Heavy-duty AFW bench scales are designed to accommodate rough handling of bulky items. The indicator rotates 135° for viewing from all angles, and the large, 1-in.-high backlit LCD display can be easily read from a distance or in difficult lighting conditions. An in-use indicator cover keeps the display safe from spillage. Bases are cast aluminum; platform covers are stainless steel; and pillars are solid rectangular tube steel. They are compact and light enough to lift and move by hand, and they operate on either built-in rechargeable batteries or an included external power adapter.

Thermal Transfer Labeling System
The MarkingGenius is a high-speed desktop thermal printer for industrial labels that is 10 times faster than a regular plotter system and can be quickly installed on your PC via LTP or USB ports. Using thermal transfer technology to produce identification and labeling media for wire marking, terminal blocks, cables, tubing, panel building components, and equipment of all types, the unit prints True Type fonts in black and over 4000 colors. This system is also capable of printing Clipart images, drawings, and bitmaps down to very small dimensions.

Counter-Rotating Sweep Agitator
The Tri-Mix Turbo-Shear agitator combines scrape-surface with high-shear. The counter-rotating, scrape-surface agitator can be designed for up to 2 million CPS products, while the Turbo-Shear head has been modified to accept several disperser designs for 10,000 CPS products alone and up to 50,000 CPS products with the aid of the counter-rotating agitator. This agitator, combined with the vessel’s vacuum and pressure rating, gives the unit versatility through using shear technology to dissolve powders, blend miscible and non-miscible solutions, and disperse pigments.

Bin Discharge System
The Airsweep bin discharge system is designed to provide on-demand flow of even the toughest materials. Each powerful pulse directs high-pressure and high-volume compressed air or gas between the material and the vessel wall to sweep product off the walls and into the flow stream. The patented nozzle design ensures an immediate reseal after each pulse, preventing clogging or material feedback. The average system uses less than 10 scfm of plant air. Installed and serviced from the outside of the vessel, the system easily retrofits to any application. Solid steel construction allows operation in high-heat, caustic, or abrasive applications.

Duct Air-Flow Measuring Probes
The Series DAFM duct air-flow measuring probes accurately measure air flow in ducts. They use evenly distributed total and static pressure measuring points to deliver an accurate measurement of flows in a duct. They can be completely installed from outside the fan, making it ideal for when proper duct locations are unavailable. With their lightweight and durable construction, in addition to their ease of installation, the probes can be used in the HVAC industry. They can be used to fit ducts ranging in diameters from 6 to 96 in.

Stainless-Steel Air Knife
The Type 316 stainless-steel super air knife offers a way to create an air barrier, blowoff, clean, and dry in highly corrosive environments. The high-volume, high-velocity airstream is ideal for blocking harmful vapors and fumes on plating operations, blowing corrosive chemicals off parts, drying pharmaceutical products, and cooling hot materials. It ejects a small amount of compressed air through a thin slotted nozzle. This uniform sheet of high-velocity air immediately pulls in surrounding room air and amplifies it at a ratio of 40:1. Air consumption is one-third that of typical blowoffs, and the noise level is extremely quiet at 69 dBa. It can withstand temperatures up to 800°F and has no moving parts to wear out. Compressed air inlets are located on each end and the bottom for easy hookup.

Wear Protection Systems
Abresist introduces two Keraflex wear protection systems, consisting of Alresist high-alumina ceramics or Kalmetall-W hard overlay welding plates vulcanized to a steel base. These systems are well suited where high abrasion and impact occur in combination. Maximum operating temperature is 176°F. Keraflex reduces noise and is well suited for use in transfer chutes in belt conveyor systems and impact zones in bunkers and silos. These systems are produced in standard panels, up to 20 sq in, with welded studs or countersunk bolting attachments. Keraflex-KRM consists of Alresist high-alumina ceramics with a tile thickness of ½ or 1 in. The thickness of the rubber is determined by the severity of the impact. It consists of Kalmetall-W hard overlay welded plates, rubber, and steel. Keraflex-KR, with 1/8 - to ½-in.-thick Alresist tile and a rubber backing only, provides for a flexible lining that is glued in place.
