Oil Filter - For Any Types of Air Screw Compressors

Oil Filter Hitachi

Oil Filters

Nam Do supplies top quality replacement Oil Filters for any types of air compressors that meet and/or exceed the original OEM quality, specifications, and performance. 

An oil filter is a filter to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Oil filters are used in many different types of air compressors. Nam Do offers a full line of oil filters for any make and model air compressors. Nam Do stocks many spin-on filters to fit your machines.

1 Importance of Compressor Oil filtration

For Kobelco Air Screw Compressor

The compressor oil filter’s task is to remove all wear-promoting impurities from the oil without separating any special additives.

In both oil free and oil injected compressors the compressor oil is used for lubrication of the compressor element bearings and drive shaft bearings as well as the gears, any dust or dirt ingression will damage the rollers of these bearings and the gear contact surfaces. Wear of the bearings or damage to the gears will eventually result in rotor contact, this will result in performance loss and reduced compressor element life.

Further damage to the bearing rollers will result in cage-breakage and ultimately complete destruction of the compressor element.
In oil-injected screws where the oil is used for sealing between the rotors and heat removal, the dust and dirt in the compressor oil will end up between the rotors and compressor element housing and result in damage of the rotors and therefore performance loss.

Our compressor oil filters are specifically designed to meet the toughest running conditions of the compressor.

Our Oil Filter Replacements come with a manufacturer's warranty that matches or exceeds the original OEM warranty and specifications.

Valvoline Comp Super 46

It also goes without saying that the quality of the oil being used is equally as important to guarantee good cooling and lubrication. For long service life and trouble-free operation, Valvoline oils are always recommended.

Air/Oil Separator - for any types of Air Screw Compressor

Air/Oil Separator

Definition:

Air/Oil  separators remove compressor lubricant from the compressed air stream. During normal operation the compressor lubricant is returned to the oil sump and the compressed air continues to the air receiver.

For Hitachi 50HP

How it works:

Most rotary screw compressors and rotary vane compressors inject compressor oil right into the compression chamber with the air being compressed. The oil servers as a coolant and a lubricant, which also absorbs the heat of compression. The main benefit of using compressor lubricant as a coolant is to create a steady air compressor operating temperature so that, no matter what duty cycle, you are creating a continuous duty air compressor.  However, injecting the compressor oil into the compression chamber also creates a problem. The compressed air is full of oil when it leaves the compressor air end. The compressor lubricant needs to be removed to protect the airsystem and to return it to the oil sump so the compressor lubricant can be used over and over again. The oil separator is the compnent that separates the compressor lubricant from the compressed air and retunrs it to the main oil sump.
