How We Test

Our measurement philosophy is simple: test compressors against the jobs they power, not just spec sheets. We combine lab instrumentation with task‑based rigs to measure delivered airflow at pressure, recovery, duty cycle, noise, moisture control, and power draw across 120V/240V/gas/battery/12V.

Delivered CFM at Working PSI

We measure mass airflow at regulated tool pressure using calibrated flow meters and orifice standards. For burst tools (nailers), we simulate real shot patterns. For continuous tools (DA sanders, die grinders, HVLP/LVLP), we run sustained loads and log pressure sag to determine true delivered CFM at 40/90 PSI and task‑specific setpoints.

Recovery and Duty‑Cycle Stress

We capture recovery time from cut‑out to cut‑in under load and run extended cycles to thermal limits to verify claimed duty cycles. We log head temperature, motor amperage, and tank pressure to detect heat‑induced drop‑off and automatic shutdown behavior.

Noise at the Operator

We measure A‑weighted decibels at the operator’s ear height, 1 meter from the loudest side, and at 3 meters in a semi‑reverberant space. We note tonal harshness and vibration, and test noise‑reduction accessories (isolation pads, enclosures) when relevant.

Power Draw and Compatibility

We log steady‑state amperage and inrush with power analyzers. For 120V units, we verify 15A vs 20A circuit suitability and soft‑start behavior. For 240V, we confirm breaker sizing and cord requirements. Gas models are tested for fuel consumption and ventilation demands. Battery and 12V rigs are tested for runtime under continuous load and recharge cycles.

Moisture Control

We measure aftercooler temperature drop, water mass captured over time, and the effect of dryers/filters on pressure and flow. Painting workflows are validated for dry‑air delivery to prevent fisheyes and blushing.

System Design and Total Cost of Ownership

Every recommendation is a system recipe: compressor, hose type/length, regulators, manifolds, air treatment, wiring, vibration isolation, and ventilation. We model electricity/fuel costs, maintenance, and expected consumables to estimate total cost of ownership and safe upgrade paths (aux tanks, aftercoolers, auto drains) without oversizing.

Test Conditions and Repeatability

We record ambient temperature, humidity, and elevation. Instruments are calibrated on schedule. Each test is repeatable with documented procedures, and we publish the key settings so you can replicate results.

Pass/Fail and Scoring

We prioritize sustained performance at pressure, stable noise levels, realistic power requirements, and safe duty cycles. Units that can’t maintain task loads or exceed practical noise/power limits are not recommended—regardless of peak specs.
