Operation

The air compressor provides on-demand compressed air to outlet locations in the space for utility use. It is typically left powered on (enabled), all the time. Be aware that it can unexpectedly start at any time. The tank pressure is typically maintained at 125 psig. When the tank pressure falls below a low-pressure set point, the unit's electric motor automatically starts to operate the compressor to rebuild/restore the tank pressure. When the tank pressure reaches a high-pressure set point, the electric motor automatically turns off, stopping the compressor. It remains enabled to automatically re-setart as needed to maintain tank pressure.

How to Turn it On (Enabled) Notice the red selector switch. Turn it from off to on. This will enable the automatic operation based on tank pressure

Safety

  • Realize the enabled air compressor electric motor can and will automatically start at any time. Avoid entangling body parts in the (potentially) rotating machinery.
  • Realize the compressed air in the tank is an energy source, even after electric power is removed. Vent the tank to atmospheric pressure before servicing to release this energy source.
  • Realize the compressed air in the lines and at outlet locations is an energy source. Use caution when making connections and initiating flow to avoid unintended consequences.
  • Compressed air is typically used to blow sawdust, metal chips, and dust from the equipment. Wear PPE (eye and ear protection) to avoid injury from contact with such debris.

Maintenance

The following should be done

Drain waste water condensate from the tank

Atmospheric air contains invisible moisture. The mechanical process of compressing this air causes the air to heat up. Hot air holds more invisible moisture. When this initially hot air (at pressure in the tank) then cools, the invisible moisture will condense from the air as liquid water. Similarly, flow-related pressure changes in the lines will also cause moisture to condense as liquid water in lines and hoses. This liquid water is a contaminate that can accumulate. It can cause rust in the equipment and liquid water droplets may be expelled with the compressed air during use.

It is a simple-enough process to drain waste water condensate from the tank on a periodic basis.

  • Notice the labeled jug and the drain outlet on the tank show in the picture.
  • Position the jug under the drain outlet
  • Slowly rotate the drain outlet fitting to open it. Tank pressure will expel waste water from the tank into the jug.
  • Rotate to close the drain outlet fitting when the flow changes from water to air and/or the jug is full.
  • Dispose of the waste water and hang the empty labeled jug back on the hook, ready for the next use.

Change the oil in the air compressor The oil in the compressor crankcase should be changed on an annual basis.

  • Eye wear
  • Secure
  • Loose
  • Do not
