Fiac New Silver 20/500 - Rotary-screw Air Compressor - 10 bar Max Pressure

The FIAC NEW SILVER 20/500 rotary-screw air compressor comes with a nominal power of 20 Hp, 15 Kw and features a compressed air suction capacity of 1900 L/min.

It features a tank with a capacity of 500 L and it is capable of producing a maximum pressure of 10 bar.

Rotary-screw air compressors are perfect for those who need an continuous production of compressed air on a long term basis.

Models with rotary-screw technology are designed for heavy-duty, continuous use, such as in business or industry.

Thanks to the non-stop productivity, they are suitable for use in machine shops, industries, etc.

Unlike classic piston air compressors, these air compressor models are also extremely silent, as the rotary-screw technology makes it possible to maintain very low noise emissions.

For full productivity of the machine, it will be necessary to bring the air compressor up to temperature when it is switched on. The process will take 7/8 minutes to reach full capacity. In addition, the maintenance operations of this air compressor model has been greatly simplified to allow the user to perform it in a few simple steps.

The operation of the air compressor can be described as follows:

• The gas passes through a suction line created between the two rotors.
• The rotation of the screws stops the input suction and the air is pushed towards the delivery output.
• The screws are made in such a way as to progressively reduce the space between the rotors and the stator and this allows for an increase in pressure.
• The last step of the operation concerns the expulsion of air from the discharge of the pump unit.

The rotary-screw air compressors are particularly suitable for those environments that require a greater air flow rate and longer operating times. Unlike piston models, they do not require a rest period, but only an initial phase during which the air compressor must reach a suitable temperature to be able to deliver the maximum pressure and flow rate.

The new air-end of the NEW SILVER range ensures high efficiency and reliability. These models feature a single-stage compression unit cooled by fluid injection, designed to achieve a greater accessibility during maintenance operations. The components subject to wear have been reduced to allow maintenance to be carried out in total autonomy and avoid unnecessary interventions that could damage the machine.

There is an independent axial electric fan installed on the side of the machine. Together with the circuit board, these components allow the air compressor to work constantly even in non-optimal thermal conditions, thus ensuring a excellent efficiency of the entire cooling system.

The air-end and the electric motor are fixed on an anti-vibration base which eliminates the transmission of vibrations to the air compressor, so as to greatly reduce noise and mechanical stress on the fixed parts of the machine.

The frame is made of reinforced sheet metal with ribs. High density washable sound absorbing panels are installed on the sides.

Noise emissions: 64 dB

The air compressor features a three-phase electric motor. The induction motor is characterised by a very long service life and low maintenance requirements. In fact, this motor is brushless, the brushes being the main component subject to wear in electric motors. The absence of this component grants high durability to the motor. It is a top product in terms of reliability, low noise, durability, energy efficiency and maintenance.

• Model: IE3
• Type: Three-phase electric
• Voltage: 400 V
• Power: 20 Hp
• Frequency: 50 Hz

It is possible to adjust the tensioning of the drive belt thanks to a plate placed under the motor sliding on guides.

The air compressor is equipped with an Easy Control 2 circuit board that manages, optimize and controls all stages of operation. Thanks to an efficient run/stop regulation, fuel consumption is also reduced.

Data readout is simple and straightforward:

• Pressure;
• Temperature;
• Hour meter for load and no-road running time;
• Protection and maintenance alarms;

The maintenance of the NEW SILVER range of air compressors has been simplified and therefore designed to be carried out in complete autonomy without the need for technicians or specialist staff. Maintenance operations can be carried out by purchasing the suitable kit for your air compressor model. The kit includes a filter set along with a specific oil for these models.

It is therefore advisable to use only spare parts designed exclusively for this range. The kit can be be purchased in the product-related "Accessories" section.

Other motor features include:

Porthole for oil level control

Rubber pads

Cooling fans

Manual holder on the back of the machine
