Why is my BLACKMER Air Compressor transfer rate so low?
- A
  Alison HarringtonAug 9, 2025
  A low transfer rate in your BLACKMER Air Compressor can stem from several issues. If equipped, the 4-way valve might be leaking; try lubricating it with a compatible stick lubricant. Worn or broken piston rings could also be the cause; check their condition by restricting the discharge line—a slow pressure increase indicates faulty rings. Other potential causes include a plugged strainer (clean the screen), a faulty compressor valve (inspect for damage), compressor drive slippage (tighten belts, check keys and flywheel), or improperly designed piping (use proper pipe sizes).

What to do if my BLACKMER Air Compressor has no oil pressure?

  William WoodsAug 14, 2025
  If your BLACKMER Air Compressor lacks oil pressure, several factors could be responsible. The oil pump relief valve may not be properly set, so adjust it accordingly. Alternatively, the oil pump itself might not be working; inspect the drive tab or stop pin for damage. A low oil level is another possibility; check and replenish as needed. Lastly, a dirty oil inlet strainer can impede oil flow, so clean it thoroughly.

What to do if my BLACKMER HD161C relief valve actuates?

  If the relief valve on your BLACKMER Air Compressor is actuating, it could be due to a valve closed downstream of the compressor; open the valve. Alternatively, there might be a line blockage downstream; locate and correct the blockage.

  Knocking or unusual noises in your BLACKMER Air Compressor can be attributed to a couple of things. Loose valves could be the culprit; tighten the valve hold-down screws. Alternatively, worn internal parts might be to blame; inspect them through the inspection plates and repair as necessary.

  Shake or vibration in your BLACKMER Air Compressor can arise from several sources.

  Gas leaking from the crankcase breather in your BLACKMER Air Compressor can be caused by a faulty or worn packing; replace the packing. Another cause might be a scored piston rod; replace the crosshead assemblies and packing. Finally, an improper seal arrangement could be the issue; refer to the section on seal arrangements.
