Frequently Asked Questions
What is the primary function of this Oil Separator Kit?
Its primary function is to separate oil from the compressed air stream efficiently, returning the oil to the system and ensuring clean, dry compressed air output with minimal oil consumption.
How does this filter contribute to safety?
The filter’s electrically connected metallic parts prevent the buildup of static electricity, thereby eliminating electrostatic discharges and reducing the risk of internal fires within the compressor.
What does “outstanding separation efficiency” mean in practice?
It means the filter achieves a very high rate of oil separation, significantly above 99%, resulting in extremely low oil carry-over, which reduces oil consumption and operating costs.
Why is a low pressure drop important?
A low pressure drop means the air flows through the filter with less resistance. This reduces the energy the compressor needs to work, directly lowering your fuel or electricity consumption.
Is this a genuine Atlas Copco part?
Yes, the part number 2901164300 is a genuine Atlas Copco component, ensuring perfect compatibility, reliability, and performance for your oil-injected screw compressor. Seadweer supplies only authentic Atlas Copco parts.
