Having problem with compressor made me very hassle, because compressor is one of important machine. Why I could say that, compressor produce compressed air that used in pneumatic machine. Our mastering machine is using pneumatic system for moving some part, rotating table and sucking the glass.

My problem are unstable pressure, no backup system and compressor always have problem. Unstable pressure it mean Mastering machine needed min 7 bar for normal operation and I don’t know how many consumption for air because name plate in compressor is 29 CFM (cubic feet per minute) its around 13 litter per second.

Actually we have 2 compressors for running normal and backup but our machine not new anymore that’s why pressure can’t reach. If I only running one machine can’t support and reach 7 bar even name plate of compressor can reach 10 bar maximum.

I try to explore deeper, the main problem is I don’t know the air consumption of machine, our compressor are too old, and some leak in pipe installation.

So for backup we need another supply for backup if something happen with both compressors. We try to bypass the neighbor factory compressor, because their compressor have two and big capacity. After calculation of installation we finally can done this one.

I try to calculate air consumption for the machine; we have two compressors with 13 litters per second if we assume both compressors running so total air consumption below 16 liters per second. And with bypass compressor we have 56 litters per second, its mean we have fourth time from each compressor and twice time from machine needed.

After this method I can solve problem, so if our compressors down we still have backup.

For note, 1 CFM is 28.3 litters/minute
