  If your air compressor has insufficient pressure, several factors could be the cause. The motor might be running too slow, or there could be a leak in the safety valve or pipe. Other potential issues include a damaged gasket, valve seat, piston ring, or cylinder. Also, check if the regulator is incorrectly adjusted and set it correctly. For the other issues, it is best to use an authorised service centre to check and repair.

  Kelly SullivanAug 9, 2025
  Abnormal noise or vibration in your air compressor can stem from several causes. A part may be loose, or there could be a foreign body inside the main compressor. The piston might be connecting with the valve seat, or moving parts could be excessively worn. If any of these issues occur, use an authorised service centre to check and repair or replace parts as needed. If the piston is connecting with the valve seat, use an authorised service centre to increase the size of the gasket.

  If the main compressor is sticking, it could be due to moving parts damaged by heat. In this case, use authorised service centre to check crankshaft, bearings, con rod, piston rings, etc and replace where necessary. It also could be caused by moving parts damaged or blocked by a foreign particle.
