The Aircraft AIRBOY SILENCE 111 AS OF E portable piston compressor is a compact, quiet and easy-to-transport compressed air solution for professional, technical and maintenance applications. It is designed to operate with an 18V battery, allowing the compressor to be used even where no mains power supply is available, such as during field service, installation work, construction-site finishing, maintenance on systems, vehicle service, agricultural machinery work, window and door installation, plumbing, electrical maintenance, workshop operations and small assembly tasks.

This product is an oil-free piston compressor, so the pumping unit does not require lubrication and routine maintenance is reduced compared with conventional oil-lubricated compressors. This feature makes it particularly practical for users who need a clean, ready-to-use machine for quick operations. The oil-free design also helps provide cleaner air for service work, blowing, inflation, technical cleaning, operation of small pneumatic accessories and pressure checks.

The 120 l/min intake capacity, 8 bar maximum tank pressure and 6-litre horizontal tank make the compressor suitable for many light and medium-duty professional applications, always taking into account the air consumption of the connected accessory. The compact tank provides a useful air reserve for mobile and intermittent work, while the dimensions of 370x355x410 mm and the weight of 14.9 kg make the compressor suitable for service vans, maintenance trolleys, mobile benches and temporary workstations.

The very quiet operation, with a noise level of 60 dB(A), is an important advantage for use in workshops, maintenance departments, technical laboratories, indoor areas, finishing sites, homes, shops and locations where noise must be kept low. The low noise level improves working comfort, especially during repeated operations or in environments where a conventional compressor would be too loud.

The compressor is equipped with an automatic pressure switch, a pressure reducer and two pressure gauges. One gauge displays the pressure inside the tank, while the other shows the working pressure at the outlet during operation. The pressure reducer allows continuous adjustment of the operating pressure, which is useful when different accessories or tasks require different pressure levels. Correct pressure adjustment helps prevent overpressure, protect pneumatic fittings and accessories, improve work quality and adapt the compressor to the specific application.

The compressed air outlet with quick coupling allows fast connection of compatible hoses and accessories, reducing preparation time and making it easier to switch between different tasks. The ball valve for condensate drainage allows the tank to be drained periodically, an important operation for keeping the compressor efficient and helping preserve the tank over time. Rubber anti-vibration feet improve stability during operation and reduce vibration transfer to the support surface.

In practical use, the pressure required by the connected accessory should always be checked, the pressure reducer should be set to the correct value and the gauges should be monitored during work. For applications with continuous or very high air consumption, the required air flow must be carefully assessed, as the 6-litre tank is designed for mobile, quick and intermittent tasks rather than continuous operation of high-consumption pneumatic tools. After use, it is good practice to drain the condensate, disconnect the accessories and store the compressor in a dry, protected place.

This product is not a dimensional measuring instrument and is not used directly to measure heights, transmission clearances, form errors or geometry errors. However, it is a highly useful support tool in technical activities where regulated compressed air must be readily available for cleaning, blowing, component preparation, machine-tool maintenance, pneumatic circuit checks, controlled inflation and service operations. In professional environments it can therefore help improve speed, order and operational accuracy during installation, adjustment, assembly and maintenance work.

The battery is not included in the standard supply. Optional accessories include the Bosch ProCORE 18V 8.0 Ah battery and the Bosch GAL 18V-160 EU battery charger, which complete the compressor configuration and make it fully operational in cordless mode. Compatibility with 18V batteries provides flexible, practical use, especially for travelling technicians, maintenance operators and professionals working in different locations throughout the day.
