The air filter shall be inspected every day.
Every day, the dust-collecting bag shall be cleared (for heavy duty air filter), and the dust cap or air inlet silencing chamber shall be cleaned. In the dusty environment, the cleaning operations shall be more frequent. If it is very dirty in the environment, it is recommended to arrange the air inlet of compressor to the place with clean air supply in the outdoor.
Every time the vacuum switch of air filter acts, or when the pressure loss reaches 25” water column, or when the indicator is lit, the filter core shall be maintained. When it operates every 500 hours or 3 months, the air filter shall be inspected for the damages and the air inlet system shall be inspected for the sealing; in the normal operating conditions, the element of air filter shall be replaced every 2000 hours or a year. If the environment condition is poor and dusty (such as ceramic, cement and etc), the maintenance and replacement intervals shall be properly shortened. For the heavy duty filter, when the main filter core is replaced, the safety filter core shall be also replaced. The safety filter core requires no maintenance during the operation.
The element has an overall structure and can congeal the oil mist on its surface to become the oil drops which will fall into the bottom of separator and then be recovered by the oil return pipe to return to the compression chamber. The separator has to be carefully handled to avoid the damages. Once the element of separator is hit and deformed, even an indentation will influence the separating efficiency, consequently resulting in the excessive oil content in the discharged air of compressor. Even a tiny hole on the component will lead to very high oil content.
In the normal case, if the air filter and oil filter are maintained in a good condition, then the periodic replacement of filter core in the oil-gas separator will not be required.
If the following conditions occur to the machine, then it will be required to replace the element of oil-gas separator:
The pressure differential switch of separator acts and the pressure differential between the front and rear sides exceeds 1.0kg.
n the case that the oil level, loading and unloading, and the oil return system are identified to be normal, the oil content in compressed air is still too high.
Every other 4,000 hours
After the new machine operates for 600 hours, the element of oil filter shall be replaced. Afterwards, it is required to replace the oil filter when the following conditions occur. For replacing the filter core, the machine shall be shut down. Wipe off the dirt and oil from the outside carefully and prevent the foreign matters from entering into the lubricating system as far as possible.
In the normal operating temperature, the filter (pressure differential) has an alarm. In this point, the pressure differential of filter exceeds 1.7 bars (25 psi).
Every time it operates for 1000 hours.
When the lubricating oil is replaced.
When the oil sample is assayed to be disqualified.
Compressor Oil Filtration
Performance of the compressor can be hampered due to dust and dirt contaminating the compressor oil thus causing damage to the rotors and their housings. Also as the same oil lubricates the compressor element bearings, damage to these vital components could potentially lead to rotor contact and service failure.
