Here is a
detailed analysis of four guys in Australia who bought a compressor to save money because they were fed up with paying for fills. They appear to have included everything but allocate labor and floor space. Operating costs less than $1 per fill and capital costs currently around $3 per fill, and decreasing.
I would think a LDS system designed for a greater volume should yield a lower cost per fill. If you use the capacity. Of course, if you spend the money to run a system that handles 1000 fills per week and only do 50, your cost per fill will be outrageous.
******************************************************
COSTS
Running Costs
Item Cost per fill
Filter $0.49
Electricity $0.07
Spares/repairs $0.20
TOTAL $0.76
1. NOTES: After way through filter 23 with 1,569 fills completed
2. The nipples and valves purchased have been amortised over a number of filters
3. The oil has been amortised over a number of filters and not all the cost has yet been reflected in the fill cost but the above represents a realistic situation.
4. Repackable cartridge will be amortised over fills 14 to 66 and included in Filter cost.
Fixed Costs
At the same time as above the purchase cost of the compressor is $3.30 per fill.
Total Cost
The total cost as I write this is $4.06 a fill. Therefore, based on $9 a fill (or even $5) we are already ahead and of course this will get even better over the coming years.
