[Leak-proof precision threads – no PTFE tape required]: The threads are precision-machined using CNC technology to strict tolerances. The metal-to-metal seal is sufficient for vacuum applications – no PTFE tape or liquid sealant is required. Faster assembly, with no risk of PTFE tape debris entering the system. [Nozzle diameter 1.5 mm / 2.5 mm – select according to air supply]: The C15HS (1.5 mm nozzle) has an air consumption of 95 L/min, making it suitable for smaller air compressors or multiple devices on a single line. The C25HS (2.5 mm nozzle) provides higher vacuum flow but requires a greater air volume. Select the nozzle size based on your compressed air capacity – not just the vacuum level. [Aluminium alloy body – rust-free in damp environments]: Unlike steel injectors that corrode internally due to damp compressed air, the aluminium alloy body remains clean. No rust particles clog the nozzle or contaminate the process. Suitable for older compressed air systems in workshops or those with poor drying performance. [Simple design – easy to maintain]: When cleaning or inspecting, the connections can be blown out directly. This is particularly important for installations in the food industry or warehouses. [Operating temperature range 0–60°C]: Suitable for indoor use only. Do not install in unheated outbuildings during winter – frozen condensation may block the nozzle. Also, keep away from heat sources exceeding 60°C – internal seals may soften. For outdoor or cold store applications, please select other models with a wider temperature range., Manufacturer: AURVIX
