Norgren Collateral

6 Vacuum Product Guide NCDF air amplifiers can achieve amplification ratios as high as 40:1 (output to input). The NCDF air amplifier's straight-through design allows dirt and debris to pass through without clogging providing maintenance-free operation. Material Conveying Vacuum Generators NDF Series The NDF Series of high flow material conveying vacuum generators provide a simple, reliable and cost effective method of in-line transfer of bulk materials, complex shapes, individual objects, and selvedge. The NDF generator's unique capability to create instantaneous vacuum flow and high air velocity, combined with its straight-through, smooth bore design allows material to pass directly through the generator at high speeds without interference or clogging. Available in 17 standard models with inside diameters from 1/8" (6mm) to 4" (100mm). Custom Materials and End Configurations For chemical compatibility, heat and environmental requirements, food and medical applications, Norgren's NDF Series offers custom materials (Teflon ® , stainless steel, PVC, PEEK), special coatings, and modified threads including internal and external threaded exhaust and/or vacuum ports with NPT or G port threads. Silencers NAA Series Silencers NAA Series silencers have excellent noise reducing characteristics with minimal resistance to air flow. The large surface of the felt element resists contamination far more than other materials such as sintered bronze, steel mesh or porous polyethylene. NST Series Silencers The NST Series Silencers are designed with a straight through flow path that eliminates clogging by allowing the contaminants to pass directly through the silencer. Even in the most adverse conditions, contaminates pass through the silencer making the NST Series ideal for silencing vacuum generators that are continuously ingesting dirt and debris. NSTAA Series Silencers The NSTAA Series hybrid silencer offers increased noise reduction by combining an NST silencer with an AA silencer. The (closed- end) AA silencer is attached to the end of a modified NST silencer, thus removing the flow through feature of the standard NST Series silencers. NFA-51 Series Silencers The FA-51 Series silencers offer remarkable noise reduction for high volume exhaust applications without causing back pressure. These silencers are ideal for quieting large air valves that must exhaust quickly to maintain high cycle rates. Vacuum Cups Extensive Variety of Profiles & Materials Norgren offers cups in an extensive variety of shapes and materials including dual durometer, FDA Approved silicone, rubber, egg vacuum cups, non-marking vacuum cups and metal detectable cups. Bellows Cups Bellows cups have a pliable outer rim that will conform to curved or uneven surfaces while the bellows sections compensate for inconsistent stack heights. Under vacuum the accordion-style bellows cup will collapse on contact. The collapsing action simulates a short cylinder stroke lifting the product a short distance, possibly saving the need for a separate lifting mechanism. Flat Cups Flat cups without cleats are flexible and work well in applications that do not require lifting heavy loads. Flat cups with cleats are strong with a rigid, low profile that will lift heavy loads. The low profile allows heavy loads to be lifted vertically without the cup "peeling" away from the product surface or deforming the object being lifted. These cups perform well when gripping smooth, flat, heavy objects such as steel, glass (television picture tubes) and coated corrugated. Oval Cups Like cleated cups, oval cups have heavy load capabilities due to their rigid design and large vacuum work area. Oval cups have the largest lifting force because they provide the most surface area for a given footprint. NCDF-37H Single Bellows Multi-Bellows
