Vacuum Product Guide 5 High Vacuum Venturi Generator HighVac Series: NHVP 100, 200, 300 The HighVac Series of air-powered venturi vacuum generators generate vacuum levels up to 29.5" Hg (999mbar) and offer a wide range of vacuum flow rates. Often used to replace expensive, noisy, heat generating, electric generators, HVP generators are quiet and maintenance free, ideal for degassing viscous liquids such as silicone and other mould compounds, vessel evacuation, and process control for small shops, labs and HVAC applications. Cylindrical Venturi Generators Ultra-Mini NJ Series: NJS-40UM The NJS-40UM (Ultra-Mini) cylindrical venturi vacuum generator is the smallest complete venturi vacuum generator that Norgren offers. Incredibly compact and powerful – it measures the size of your finger tip and generates up to 27"Hg (914mbar). Lightweight, quite and cool operating, NJS-40UM generators fit in confined spaces, where they can be mounted in-line near the point of use for rapid response. Ideal for gas sampling and analysis, leak testing, portion/drip control for dispensing liquids, liquid transfer, pick and place for small, non-porous parts, and small vessel evacuation. This generator is used as the vacuum source for Norgren's vacuum pencil kit. Cylindrical Venturi Generators Mini NJ Series: "M" (mini) Version The NJ Series "M" (Mini) version cylindrical venturi vacuum generators feature a high power-to-size ratio, measuring only 3"L x 3/4" OD. Single stage design allows ingested contaminants to pass through the generator without clogging enduring continuous operations. No seals and no moving parts. Rugged and reliable. Ideal for carton erecting, vessel evacuation, medical and pharmaceutical applications, food processing, high temperature and caustic applications. Mid & Max NJ Series NJ100, 150, 200, 250, 300 & 350 The larger NJ Series generators offer higher vacuum flows for rapid evacuation of large vessels and to overcome leakage to sustain high vacuum levels when handling porous materials. The single-stage design allows ingested contaminants to flow through the generator without clogging, ensuring continuous operation. Constructed of a single material, with no seals or moving parts, NJ Series generators are virtually indestructible. NJ Series generators provide a constant vacuum flow, rather than a fluctuating flow typically associated with diaphragm generators. They operate with an instantaneous response in pulsed applications or on a continuous basis. Ideal for carton erecting, vessel evacuation, medical and pharmaceutical applications, food processing, high temperature and caustic applications. Cylindrical Generators Ideal for Specialty Materials The NJ Series generators can be manufactured in a variety of materials, including Teflon®, stainless steel, PVC, PEEK making them ideal for use in adverse operating conditions. With a straight through design, contaminants pass through without clogging. Press fit nozzle, no seals or o-rings. Custom sizes and shapes available. Inline Venturi Vacuum Generator Unlike standard venturi vacuum generators where the vacuum port is 90° from the supply port, Norgren's air-powered NVPI-90H inline venturi vacuum generators feature an air-supply port and vacuum port on the same axis to consolidate space. NVPI-90H generators vertically mount to robotic arms to create single or densely populated arrays of generator/cup to accommodate and lift products of any size, shape, or weight. Internal threads on the vacuum port enable vacuum cups to connect directly to the generator while the external threads attach directly to the end of arm tool. NVPI-90H's feature an additional vacuum port for a vacuum switch/ sensor to ensure accurate part detection or for a connection to an externally supplied blow-off. Variable Vacuum/Variable Flow, Extremely Dirt Tolerant Venturi Vacuum Generators NVDF Series The NVDF Series is a unique Norgren innovation that places the vacuum port and exhaust path inline making a straight-through venturi vacuum generator. These compact generators offer high flow rates up to 120 SCFM (3400 LPM) and high vacuum levels up to 25"Hg (847mbar). Developed for extremely dirty and dusty environments such as foundries, refractory and bagging operations, NVDF generators don't clog, lose suction or require a vacuum filter. NVDF generators are field-adjustable allowing you to regulate the vacuum flow and vacuum level to meet your application requirements. Also available with new factory preset option. Adjustable Air Amplifiers/Blowers NCDF Series Air Amplifier Blower: High Output Flow The NCDF Series air amplifiers generate high output flow using a small volume of compressed air. This efficient use of air makes NCDF air amplifiers a cost-effective alternative to electric blowers or raw compressed air. Ideal for inflation and deflation, drying, cooling, blowing, air, smoke, mist or fume evacuation. Field adjustable for individual applications. No heat generated, no electricity required. Safe operation. CDF Series Air Amplifier Material Handling: High Vacuum Flow CDF Series air amplifiers generate high vacuum flow, overcoming leaks inherent in handling porous objects such as foam or fabric and other materials that many consider too challenging to handle with vacuum. With or without a vacuum cup, CDF air amplifiers safely transfer irregular shaped items. To meet a wide range of applications, air velocity and air flow are field adjustable to compensate for the pressure level supplied. NVDF-37 NCDF-50H NVPI-90H
