Sumitomo F50 Compressor Manual

Typically 200V, 380V, 400V, or 480V AC (model-dependent), 3-phase, 50/60 Hz Static Pressure: ~1.60 to 1.65 MPa (at 20°C)

Must remain between 5°C and 35°C. High ambient temperatures degrade the compressor oil rapidly.

The gas passes through an Adsorber (active charcoal layer) to ensure high purity before being sent back to the cold head via the supply line. 3. Installation & Safety Guidelines

Press the button. The compressor will hum, and the pressure gauges will split into High and Low operating zones within a few seconds. How to Charge Helium Gas sumitomo f50 compressor manual

Before diving into search techniques and PDF downloads, it is vital to understand what makes this specific manual so important. The Sumitomo F50 is a heavy-duty, oil-injected rotary screw compressor, typically operating in the 50 horsepower (37 kW) range. Unlike simpler piston compressors, screw compressors require precise timing, specific lubricants, and calibrated pressure settings.

Ensure a dedicated three-phase circuit breaker is used. Check the phase rotation during installation; reverse rotation can severely damage the internal compressor scroll.

To ensure safe and efficient operation, follow these general guidelines: Typically 200V, 380V, 400V, or 480V AC (model-dependent),

Inspect the heat exchanger for mineral scaling if using hard water. Flush with a mild descaling agent if necessary. Every 30,000 Operating Hours (Major Overhaul)

Check chiller function; verify water flow rate; flush heat exchanger with descaling solution. Helium gas leak; Improperly tightened Aeroquip couplings.

Every 20,000 operating hours or every 2–3 years (whichever comes first). How to Charge Helium Gas Before diving into

Run the compressor for 10 minutes to circulate and mix the gas.

The F-50H/SH requires a steady supply of cooling water (4--28°C) to manage high-pressure helium, as outlined in the technical manual. Electrical Installation
