How do you calculate good cylinder fill capacity?

Multiply cylinders per cycle by available cycles, then multiply by uptime and accepted yield. Here 8 × 42 × 0.88 × 0.97 = 286.8 good cylinders from a 336 gross.

What is the difference between gross and good fill capacity?

Gross capacity is the theoretical maximum if nothing went wrong — 336 cylinders. Good capacity subtracts downtime and rejects, landing at 286.8 ship-ready cylinders, the number you should actually quote.

How much capacity does downtime cost on a fill line?

In the example, 88% uptime erases about 40.3 cylinders of capacity before yield is even considered. That availability loss is usually the biggest and most addressable bucket.

What is a good accepted fill yield for suppression cylinders?

Well-controlled clean agent and CO2 fill stations run 97-99% accepted yield, rejecting on fill weight, leak check, or valve seating. The example's 97% costs about 8.9 cylinders of rework or scrap allowance.

Should I improve uptime or yield first?

Compare the two loss buckets. Here downtime costs 40.3 cylinders versus 8.9 from rejects, so chasing the availability loss — faster scale settling, fewer micro-stops — returns far more good output than a yield project.

Does this account for cylinder size differences?

No. The cylinders-per-cycle figure assumes a consistent size and fill weight. Mixing large and small cylinders in one cycle count distorts capacity, so run the calculation per cylinder family.

Cylinder Fill Capacity Calculator

Cylinder fill capacity is the number of good, ship-ready suppression cylinders a fill station can produce in a period after you account for both downtime and rejects. Operations managers filling clean agent, CO2, or dry-chemical cylinders use it to commit realistic ship dates instead of quoting gross capacity that ignores real-world losses. A fill line that looks like it can do 336 cylinders on paper rarely does, because regulator settling, scale recalibration, and weight or leak rejects eat into the total. This calculator separates gross capacity from the availability loss and the reject allowance so you can see exactly where your good output goes and which loss is worth attacking first.

What this calculator does

Estimate good fire suppression cylinder filling output from cylinders per fill cycle, available cycles, fill station uptime, and accepted fill yield.
Use it when planning clean agent, CO2, dry chemical, nitrogen, or stored-pressure cylinder filling capacity.
It multiplies cylinders per cycle by available cycles for gross capacity, then applies uptime and accepted yield to give good, ship-ready output.

Formula used

Gross cylinder fill capacity = cylinders filled per cycle × available fill cycles
Good capacity = gross capacity × uptime × yield

Inputs explained

Cylinders filled per cycle:
Available fill cycles:
Fill station uptime:
Accepted fill yield:

How to use the result

Use it when committing fill-line ship dates, sizing a shift to a backlog, or quantifying how much capacity downtime and rejects are quietly costing you.
It uses single average figures for uptime and yield; a station with a clogging fill head or a drifting scale produces clustered failures that a flat percentage cannot predict cycle by cycle.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
U.S. housing starts run at 1,177k per year (Census, May 2026), down 8.7% from a year earlier, the demand driver for building products.
