How do you calculate good paint booth capacity?

Multiply units per cycle by available cycles for gross capacity, then multiply by uptime and yield. Here 4 x 480 = 1,920 gross, x 90% x 97% = 1,676.16 good units.

What is the difference between gross and good capacity?

Gross (1,920 in the example) is the theoretical maximum if the booth never went down and every coat passed. Good capacity (1,676.16) is what you can actually ship after 192 units of uptime loss and 51.84 units of yield loss.

How much capacity am I losing to downtime versus coating defects?

In the example, uptime costs 192 units and yield costs 51.84 units. Downtime is the bigger lever here, so booth availability improvements would return more than chasing recoat yield.

What is a good booth uptime for a finishing line?

Well-run powder or wet booths hold 85-92% scheduled uptime once cleaning, color change, and filter swaps are accounted for. The 90% in the example is solid; below 80% signals a maintenance or changeover problem.

Why isn't yield loss just 3% of gross?

Yield is applied after uptime, so the 3% loss is taken on the already-reduced 1,728 units (1,920 x 90%), giving 51.84 units — not 3% of the full 1,920.

How do I set units per cycle for mixed pump sizes?

Use a rack-weighted average — if small pumps let you hang 6 and large ones only 2, blend by your typical mix. For accuracy on a wide size range, run the calculator separately per part family.

Pump, Compressor & Rotating Equipment Assembly calculator

Paint Booth Capacity Calculator

Paint booth capacity estimates how many good, coated pump or compressor assemblies a booth can actually deliver over a period, after uptime and coating yield losses are taken out of the gross count. Finishing supervisors and capacity planners use it to check whether the paint line can keep pace with assembly and to see where output is being lost. It matters because the booth is often the sole finishing chokepoint on a rotating-equipment line — a flash-off constraint, a cure oven, or a recoat-heavy yield problem there caps the whole plant's shippable rate. Separating gross capacity from uptime and yield losses tells you exactly which lever to pull.

What this calculator does

Paint booth capacity estimates how many good, coated pump or compressor assemblies a booth can actually deliver over a period, after uptime and coating yield losses are taken out of the gross count.
Use it when paint booth capacity in pump, compressor and rotating equipment assembly is being asked to take on more work and you need to know if there is room.
It multiplies units per cycle by available cycles for gross capacity, then discounts by uptime and yield to give good output capacity.

Formula used

Gross paint booth capacity capacity = units per cycle × available cycles
Good capacity = gross capacity × uptime × yield

Inputs explained

Assemblies coated per booth cycle:
Available booth cycles:
Booth uptime:
Coating first-pass yield:

How to use the result

Use it to check whether booth finishing capacity can support the assembly rate and to quantify capacity lost to downtime versus coating defects.
It uses a single average units-per-cycle; mixed part sizes that load the booth differently will make one blended figure less accurate than modeling by part family.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
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).
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
