Maintenance
6.1.3 Use genuine spare parts
It is very important to use genuine spare parts, to ensures that your compressor work as new for its lifetime. Spurious
spares may seem less expensive initially, but they severely compromises on quality. Spurious parts will prove cost-
ineffective in the long run, and may even result in total damage of the machine or cause serious accidents. The table
includes certain critical spurious parts. It is not an exhaustive list, and you are strongly advised to avoid all other spurious
spares that this table does not cover. Be aware of the consequences of using spurious spares including but not limited to the
ones described in the table.
Effect Spurious part Remarks
Air oil separator
Due to dense filtration media, it creates in additional pressure drop and so causes
additional power consumption. Every1 bar (14.5 psi) of pressure drop results in ~7%
additional power consumption.
Higher power
consumption
Lubricant
Spurious oil loses its properties soon and may get solidified causing the rotor to
malfunction.
Reduced
performance
Air oil separator
This imposes 10% additional resistance for air flow and creates more pressure drop
and thus additional load on motor. Inadequate separation deteriorates air quality,
reduce the performance, and damages downstream components. It also results in
huge oil loss (1L / 200hr).
Oil filter
Contaminants are not filtered properly and the contaminated oil affects the critical
parts of airend. Thus it reduces performance and life (33% reduction) of the air end,
air oil separator etc. Contaminated oil also cause clogging and reduces the cooler
performance.
Air filter
Dust carries over to the system and causes the same problems as caused by the
spurious oil filter
Safety hazard Air oil separator
Inadequate earthing can cause a separator to collapse (25% risk). Inadequate
earthing can also cause fire and destroy the entire machine.
Cost
Higher power consumption means a higher operating cost.
Reduced performance leads to extra functioning and operating cost.
Spurious parts will damage the other components and accelerate maintenance
frequency and cost.
Higher consumption of consumables like oil (due to the use of spurious parts) will
result in, increased cost.
