Air Compressor Service Hour Tracker
Forecast the next oil & separator service for your rotary screw compressor from hour-meter readings — hours left, days left and a calendar date.
With your numbers: 6,800 − 4,800 = 2,000 h since service; interval 2,000 h leaves 0 h ÷ 14 h/day = 0 days. Follow the OEM service schedule where it differs.
Field notes from maintenance practice
Compressor service economics hide in the differential pressure: a loaded separator or clogged filters add ΔP that the motor pays for around the clock (~7% more energy per extra bar). Tracking hours here, and ΔP gauges on the machine, together tell you whether to service on the hour ladder or pull the service forward because the element loaded early in a dusty summer.
Watch discharge temperature alongside hours: a rising trend at the same ambient means the cooler or the oil is going off before the schedule says so. Convert the forecast date into action: order filters/parts when the tool shows ~2 weeks remaining, and book the technician at one week. Usage-based scheduling beats calendar-based for any machine whose duty varies — a calendar plan over-services the lightly used unit and under-services the busy one.

About Air Compressor Service Hour Tracker
This forecaster turns two hour-meter readings into a service plan for a rotary screw compressor: enter the meter now, the meter at the last oil & separator service, the interval, and average daily use — it returns hours remaining, days remaining and the calendar date to book the work. Rotary screw compressors commonly service oil and filters every 2,000–4,000 h (8,000 h for premium synthetic oils) and the air/oil separator every 4,000–8,000 h — the machine's service manual gives the exact ladder.

Frequently asked questions
What is the right oil & separator service interval for a rotary screw compressor?+
Rotary screw compressors commonly service oil and filters every 2,000–4,000 h (8,000 h for premium synthetic oils) and the air/oil separator every 4,000–8,000 h — the machine's service manual gives the exact ladder. Severe duty — dust, high ambient temperature, heavy loading, short cycles — typically halves the interval, and OEM schedules list separate 'severe service' columns. When in doubt, sample the fluid/condition at the standard interval once and let the result calibrate your real interval.
Premium synthetic compressor oil costs triple — does the 8,000 h interval justify it?+
Usually yes for machines that run: at 6,000+ h/year, synthetic at 8,000 h vs mineral at 2,000 h saves three service events annually (oil, filters, labour, disposal and downtime), typically beating the oil premium severalfold — plus better varnish control protects the airend. For lightly used machines (<1,500 h/yr) the calendar limit dominates anyway and mineral oil is fine. Run your numbers per machine.
My usage varies a lot week to week — does the forecast still work?+
Yes — enter your average daily hours over the last month or two, and refresh the reading every week or two. The forecast date self-corrects as the meter advances. For strongly seasonal equipment, use the season's typical daily hours rather than the annual average.
Hour-meter PM or calendar PM — which should govern?+
Whichever comes first, as most OEM schedules state (e.g. '250 h or 6 months'). Oil oxidises and seals dry out with calendar time even on a parked machine, while wear tracks running hours. This tool handles the hours side; put the calendar limit in your diary as the backstop.
