Atlas Copco Ga7ff Parts Manual

Here’s what you can do:

OEM vs. aftermarket trap: The manual shows O-rings with standard AS568 dash numbers, but Atlas Copco often specifies a different durometer (hardness) or material (FKM vs. NBR) to withstand high-temperature condensate acidity. Aftermarket equivalents frequently fail within 2000 hours. atlas copco ga7ff parts manual

5. Refrigerant Dryer Components (FF specific)

  • Expansion Valve: Regulates refrigerant flow.
  • Drain Valve (Electronic or Pneumatic): A common failure point. The manual provides wiring diagrams.
  • Filter Dryer (refrigerant circuit): Prevents moisture/acid in the sealed system.
  • Part Number: The unique code for ordering.
  • Description: The name of the part.
  • Quantity: How many are required (vital for service kits).

Gotcha #2: The Drive Belt Part Number The GA7FF uses a specific XPA belt profile. The manual gives the length (e.g., XPA 1032). Do not buy a generic auto parts store belt. The manual specifies the Atlas Copco part number because their belts are anti-static and oil-resistant. A standard belt will crack in 100 hours. Here’s what you can do: OEM vs

  • Air filter element
  • Oil filter element
  • Oil separator element
  • O-ring set for separator cover
  • Oil (quantity specified separately)

2. The Separator Tank & Oil System

This is where the manual saves you from a catastrophic mess. Expansion Valve: Regulates refrigerant flow

The GA 7FF (Fixed Speed, Full Feature) is a 7.5 kW (10 HP) oil-injected rotary screw compressor, capable of delivering up to ~1.2 m³/min at 7.5–10 bar. Its "FF" designation means it includes an integrated refrigerant air dryer—making the parts manual a study in thermal integration, condensate management, and compact packaging.

  • The Oil Separator Element: The manual lists specific part numbers (e.g., 2901-1605-00). Crucially, the exploded view shows you the stacking order of the gaskets. If you put the O-ring below the element instead of above, you will dump oil into your air lines.
  • Minimum Pressure Valve (MPV): Part 2901-1018-00. The manual doesn't just show the valve; it shows the internal spring and seal kit. If your compressor won't build pressure, rebuild this valve using the diagram—don't replace the whole unit.
