Knowledge base
Practical answers from the parts trade: why discharge pressure drops, why oil carries over, and how to match part numbers with confidence.
Most complaints about 'wrong parts' are actually part-number mismatches. A short method for cross-referencing compressor spares - what data to send, what to verify, and why supplier answers differ.
Screw compressor services stack at running-hour marks - and in real workshops the calendar matters less than the duty cycle. What to replace at each stop, and how often in practice.
Oil in your compressed air line usually points to the oil separator or the oil return circuit - not to the compressor oil itself. Here are the root causes to check, in order of likelihood.
Low discharge pressure is one of the most common screw compressor faults. Work through these four causes - filter blockage, leaks, intake valve, and sensor signals - before touching the machine.
