General Description

The Atlas Copco GA90VSDFF is a high performance industrial compressor, designed to meet compressed air needs in industrial applications. This model, equipped with a 90 kW motor and frequency converter for speed regulation, is appreciated for its energy efficiency and ability to adapt to different operating conditions. Being a used machine, you may find signs of wear, but with proper maintenance control, the compressor can continue to function optimally for a long time.

Components and Construction

1. Electric motor : 90 kW, high efficiency, operates at variable speed, allowing precise adaptation to compressed air demand.
2. Air Cooling System : Maintains the compressor at a stable operating temperature, improving efficiency and component life.
3. Built-in dryer : Uses R404a refrigerant to ensure moisture-free compressed air, essential in many industrial applications.
4. Frequency converter : Regulates the speed of the compressor based on demand, reducing energy consumption and extending the useful life of the components.
5. Oil Injection System : For internal lubrication and friction reduction, improving the overall efficiency of the machine.

Technical Characteristics

• Engine power : 90 kW
• Maximum pressure : 12.8 bar
• Volumetric flow rate (FAD) : From 1.09 m³/min to 17.07 m³/min (at 7 bar)
• Cooling type : Air-cooled
• Built-in dryer : Refrigerated dryer with R404a refrigerant

Formulas for the Calculation of Optimal Parameters

1. Power absorbed (P) :
   P=Q×Δp×1ηP = Q \times \Delta p \times \frac{1}{\eta}
   $P$ $=$ $Q$ $\times$ $\Delta$ $p$ $\times$ η 1 ​Where

   • QQ $Q$ = Volumetric flow rate (m³/min)
   • Δp\Delta p $\Delta p$ $=$ Pressure difference (bar)
   • η\eta $\eta$ = Compressor efficiency

2. Calculation of energy consumption :
   E=P×tE = P \times t
   $E$ $=$ $P$ $\times$ $t$ Where:

   • PP $P$ = Power absorbed (kW)
   • tt $t$ = Operation time (h)

Workable Materials

The Atlas Copco GA90VSDFF compressor provides high quality compressed air, essential for processing a wide range of materials in sectors such as:
