Inpro/Seal company now offers two shaft-sealing systems for the containment of powders, abrasives, liquids and toxic vapors: the Air Mizer-PS and the Articulating Air Mizer-PS with upgraded design features.
The Air Mizer product line was developed to use minimal amounts of air pressure to seal shafts where dry particulates, powders and bulk solids are handled, processed, packaged and stored. They can be installed on screw conveyors, mixers, blenders, rotary valves, feeders, gates, clinker grinders, bucket elevators, diverters, scales, bagging machines, dust collectors, discharges, classifiers, screens, extruders, separators, shredders, sifters, gate valves, metal detectors, pulverizers, crushers, coolers, augers, transfer pumps, fillers and similar dry powder and bulk processing equipment.
the Articulated Air Mizer-PS has all the features of the original Air Mizer-PS and adds the ability to handle extreme shaft run-out and deflection, common in these kinds of applications to provide a seal that conventional methods simply cannot attain.
Inpro/Seal modified its compound labyrinth bearing isolator to incorporate air as an extra sealing solution. As with all Inpro/Seal Bearing Isolators, the original Articulating Air Mizer-PS is a non-contact seal that avoids direct egress of the particulate material and assures the highest levels of performance. Its major innovation is the inclusion of a design feature that uses a solid wall of air that functions as a barrier for contamination and works to retain product where it should be — in the equipment, not outside of it.
The improved Articulating Air Mizer-PS offers all the same advantages of its predecessor including the ability to handle extreme shaft misalignment and deflection, common in these kinds of applications and provide a seal that conventional methods simply cannot attain. It was developed as a direct result of direct customer requests, input and feedback, continuous R & D and extensive field-testing. The improved Articulating Air Mizer-PS now utilizes an air barrier directly on the shaft, allowing for unlimited axial movement without placing any stress or strain on the product. Without any rotating parts, the shaft “floats” in the seal attaining zero contact and zero wear.
Working with shaft diameters of ½ inch – 36 inches, end users obtain the latest in non-contacting technology with an air purge that accepts severe radial and angular shaft run out up to ¼ inch. It will help end users boost equipment reliability, reduce costs, extend sealing efficiencies and increase bottom line results, without equipment modifications.
