Abac Formula I and Abac Formula IE - Variable Speed Compressor

The Abac Formula I and Abac Formula IE compressor is an inverter compressor for industrial use. The rational positioning of components, including air filters , oil filters and belts allows for quick and safe maintenance . The maintenance kit guarantees reliable and efficient operation.

Robust screw compressor , for intensive industrial use. Abac Formula in the Formula I and Formula IE versions differ from fixed speed compressor models due to the presence of an inverter system , which allows the motor speed to be varied based on compressed air consumption .

Abac Formula features efficient cooling for a powerful compressor: with fan and coolers , the cooling of this screw compressor is efficient even in the most difficult working conditions .

Available models

Abac compressors can be selected from the drop-down menu:

• Formula I: basic compressor + inverter
• IE formula: basic compressor + inverter + integrated dryer + in-line filter

Common features

Compact design

This compressor offers quality treated compressed air while taking up the smallest possible space .

Great handling

Liftable from the left and right side, Abac Formula I and Formula IE are easy to move and quick to install. The Abac Formula offer high quality treated compressed air, with minimum space requirements.

Complete control panel

Infologic2 / Airlogic2 controllers provide easy access to menus and all the key performance indicators needed to drive operation. Features control interface to drive operation, with remote control for up to 6 compressors . Scheduled routine maintenance , fault log and other functions.

Powerful cooling system

A radial fan is keyed to the crankshaft to ensure more efficient cooling of the oil and air . An independent engine cooling system ensures ideal temperatures for its operation even in extreme conditions.

New generation screw group

The new generation of these screw units guarantees great efficiency in terms of air output, great solidity and notable reliability .

How an inverter compressor works

In a variable speed compressor like Abac Formula I and Abac Formula IE the variable speed curve is different thanks to the regulation of the screw unit speed based on the air demand and the consequent production of only the quantity necessary for the specific job. This is done thanks to a pressure sensor that reports the pressure value to the controller which, in turn, sends a signal to the inverter with information on the situation. The inverter is used to regulate the motor speed based on the pressure settings .

Variable Speed Compressor Advantages

Gradual start-up

In Abac Formula compressors, the peak current absorption required for start-up is reduced, protecting the motor and reducing energy consumption.

Constant air pressure

By maintaining a constant starting pressure, Abac Formula I and Abac Formula IE avoid machine unloading operations with consequent waste of energy.

High efficiency motor

These compressors have greater energy efficiency with the use of IE3 motors .

Quiet working environment

Abac Formula features excellent insulation that ensures low noise levels and allows the machine to be positioned close to the workplace without disturbing the surrounding environment.
