Contactless transport system

Vacuum technology

The Aventics non-contact transport system NCT moves workpieces on an air cushion without mechanical contact with the surface. The range includes the NCT-AL series in aluminium (widths 20, 30, 40, 60, 100 mm) and the NCT-PK series in PEEK plastic (widths 20, 30, 40, 60 mm). The air nozzles generate uniform positive pressure beneath the workpiece, which floats and is transported in the conveying direction with low force. Both series are supplied under Aventics part numbers R412010372-R412010640 (aluminium) and R412014866-R412014869 (PEEK).

The NCT system operates with compressed air that exits downward through precisely manufactured nozzle rows, building a load-bearing air cushion. The workpiece floats on this cushion with no contact with guide rails or conveyor belts. For directional conveying, the airflow is angled slightly. The width of the NCT module is matched to the workpiece size; multiple modules can be arranged in parallel. Compressed air consumption depends on the selected width, system pressure, and number of modules.

Typical applications: Non-contact transport of semiconductor wafers and display glass in the semiconductor industry (NCT-PK/PEEK), conveying of double-sided coated PCBs without surface contact in electronics assembly, transport of solar cells and thin-film modules, gentle conveying of freshly printed or lacquered surfaces, and cleanroom transport lines for miniaturized components.

What is the Aventics contactless transport system and which industries use these pneumatic solutions?
The Aventics contactless transport system represents advanced pneumatic vacuum technology that moves materials without physical contact using compressed air flow and vacuum generation. These systems eliminate friction-based wear through non-contact operation, making them essential for semiconductor manufacturing, pharmaceutical production, precision assembly lines, and cleanroom environments where contamination must be avoided. The technology integrates seamlessly with existing pneumatic infrastructure while providing precise material handling for delicate components, wafers, glass substrates, and sensitive electronic parts that cannot tolerate mechanical contact during transport.
What are the key technical selection criteria for Aventics NCT series contactless transport systems?
Selection of Aventics NCT contactless transport systems depends primarily on bore diameter ranging from 20mm to 100mm across the NCT-AL aluminum series and 20mm to 60mm in the NCT-PK PEEK series. Operating pressure requirements typically range from 6 to 8 bar for optimal performance, while payload capacity varies with bore size from lightweight electronic components up to several kilograms for larger assemblies. Material compatibility becomes critical when selecting between aluminum housing for general applications and PEEK construction for chemical resistance, high-temperature environments, or applications requiring FDA compliance in food and pharmaceutical processing.
Which international standards and certifications apply to Aventics contactless transport systems?
Aventics contactless transport systems comply with ISO 8573 compressed air quality standards for contamination control and ISO 4414 pneumatic system safety requirements. The systems meet EN 1012 compressor and compressed air system standards while adhering to ATEX directives for potentially explosive atmospheres when specified. Cleanroom applications benefit from ISO 14644 compliance for particulate contamination control, and the PEEK series variants often carry FDA CFR 21.177 approval for direct food contact applications, ensuring comprehensive regulatory compliance across diverse industrial sectors.
What are the main differences between Aventics NCT-AL aluminum and NCT-PK PEEK contactless transport system variants?
The NCT-AL aluminum series offers bore sizes from 20mm to 100mm with standard industrial durability and cost-effectiveness for general manufacturing applications, while the NCT-PK PEEK series provides bore sizes from 20mm to 60mm with superior chemical resistance and FDA compliance for pharmaceutical and food processing. PEEK variants withstand aggressive cleaning agents, steam sterilization up to 180°C, and maintain dimensional stability in high-temperature applications where aluminum would degrade. The aluminum series delivers higher payload capacity in larger bore sizes but lacks the biocompatibility and chemical inertness required in regulated industries where the PEEK series excels.
What are the installation requirements and system compatibility specifications for Aventics contactless transport systems?
Aventics contactless transport systems require compressed air supply at 6-8 bar with ISO 8573 quality class 1:4:1 for optimal performance and integrate through standard pneumatic fittings compatible with existing infrastructure. Installation demands precise alignment within ±0.1mm tolerance and rigid mounting to prevent vibration-induced performance degradation, while electrical connections utilize standard 24VDC control signals for automation integration. The systems connect via M5 or G1/8 pneumatic ports depending on bore size and require filtered, lubricated air supply with moisture content below 50mg/m³ to maintain consistent vacuum generation and prevent internal component contamination.
What safety ratings and operating parameters define Aventics contactless transport system performance limits?
Aventics contactless transport systems operate safely within 6-8 bar pressure range with IP65 protection rating against dust and water ingress for standard industrial environments. Operating temperature spans -10°C to +60°C for aluminum variants while PEEK series extends to +180°C for high-temperature applications including steam sterilization cycles. Maximum flow rates reach 1000 Nl/min depending on bore diameter, and vacuum levels achieve up to 80% vacuum relative to atmospheric pressure. The systems maintain fail-safe operation through integrated pressure monitoring and automatic shutdown when operating parameters exceed design limits, ensuring personnel safety and equipment protection.
What maintenance intervals and service life expectations apply to Aventics contactless transport systems?
Aventics contactless transport systems require quarterly inspection of pneumatic connections, annual replacement of filter elements, and comprehensive service every 8760 operating hours or 12 months under normal industrial conditions. The contactless design eliminates mechanical wear components, extending service life to 10-15 years with proper compressed air quality maintenance and adherence to ISO 8573 contamination standards. Critical maintenance includes monthly verification of vacuum levels, quarterly calibration of pressure sensors, and annual inspection of PEEK sealing elements which may require replacement every 2-3 years depending on operating temperature and chemical exposure in aggressive environments.
