• Airflow Range (High): 278–295 NL/min
• Airflow Range (Low): 239–248 NL/min
• Air Pressure Range (High): 0.75–0.83 psi
• Air Pressure Range (Low): 0.55–0.61 psi
• Test Date: 2025-04-19

Test Overview

Test Equipment & Setup

Test Procedure

1. Pre-test: Label and inspect each sample unit (7#, 8#, 9#) for physical integrity before testing.
2. Setup: Connect the HB2 hair dryer to the airflow and air pressure measurement instruments.
3. High Speed Test: Set the unit to high speed (高档) and record airflow (NL/min) and air pressure (psi).
4. Low Speed Test: Set the unit to low speed (低档) and record airflow (NL/min) and air pressure (psi).
5. Repeat: Perform the above procedure for all three samples.
6. Post-test: Record all readings in the data table and note any anomalies in the remarks column.
7. Acceptance Criteria: Values should be consistent across samples; no remarks were recorded for any unit.

Test Data & Results

Airflow Test Data (NL/min)

All three samples demonstrated stable airflow output at both speed settings. Sample 7# and 9# recorded the highest airflow at high speed (295 NL/min and 289 NL/min respectively), while sample 8# was slightly lower at 278 NL/min. Low-speed readings were tightly grouped between 239 and 248 NL/min.

Air Pressure Test Data (psi)

Samples 7# and 9# produced identical air pressure readings at both settings (0.83 psi high / 0.61 psi low). Sample 8# measured slightly lower at 0.75 psi high and 0.55 psi low. The spread across all samples is within a narrow range, indicating good unit-to-unit consistency.

Frequently Asked Questions

What airflow does the ETENWOLF HB2 hair dryer produce at high speed?

The HB2 produces between 278 and 295 NL/min at high speed across the three tested samples, with an average of approximately 287 NL/min.

What air pressure does the ETENWOLF HB2 generate at low speed?

At low speed, the HB2 generates between 0.55 and 0.61 psi across tested samples, with two of three units recording 0.61 psi.

How consistent is the ETENWOLF HB2 across different units?

The three tested samples (7#, 8#, 9#) showed strong consistency. Airflow varied by no more than 17 NL/min at high speed and 9 NL/min at low speed. Air pressure varied by no more than 0.08 psi across all measurements, indicating reliable unit-to-unit production quality.

Does the ETENWOLF HB2 have multiple speed settings?

Yes. The HB2 features at least two speed settings — high (高档) and low (低档) — both of which were measured in this test for airflow and air pressure performance.
