Test Procedure
- Pre-Test: Inspect all three P400 units for physical defects. Confirm unit power supply is within specification. Prepare large air nozzles (大气嘴) and verify calibration of airflow and pressure measurement instruments.
- Configuration 1 — Both Ports with Nozzles: Fit large air nozzles to both outlet ports. Power on the unit. Record airflow (NL/M) and air pressure (psi) at any outlet port for each of the three samples.
- Configuration 2 — Mixed (Nozzle + Open Port): Fit a large air nozzle to one outlet port; leave the other port open without a nozzle. Power on the unit. Record airflow and air pressure separately at (a) the nozzle port and (b) the open port for each sample.
- Configuration 3 — Both Ports without Nozzles: Remove all nozzles. Power on the unit. Record airflow (NL/M) and air pressure (psi) at any outlet port for each of the three samples.
- Post-Test: Power off all units. Record all measurements in the data sheet. Compare results across samples for consistency. Flag any anomalies in the remarks (备注) column.
- Acceptance Criteria: All three samples must produce consistent airflow and pressure readings across configurations. No remarks were recorded, indicating all samples met expected performance.
Test Data & Results
B7 Airflow Test Data (B7风量测试数据)
| Sample No. (编号) | Both Ports with Large Nozzles — Any Port Airflow (NL/M) | Mixed Config — Nozzle Port Airflow (NL/M) | Mixed Config — Open Port Airflow (NL/M) | Both Ports without Nozzles — Any Port Airflow (NL/M) | Remarks (备注) |
|---|---|---|---|---|---|
| 1# | 245 | 225 | 488 | 450 | |
| 2# | 241 | 217 | 485 | 450 | |
| 3# | 247 | 237 | 487 | 434 |
B7 Air Pressure Test Data (B7风压测试数据)
| Sample No. (编号) | Both Ports with Large Nozzles — Any Port Pressure (psi) | Mixed Config — Nozzle Port Pressure (psi) | Mixed Config — Open Port Pressure (psi) | Both Ports without Nozzles — Any Port Pressure (psi) | Remarks (备注) |
|---|---|---|---|---|---|
| 1# | 2.17 | 1.96 | 2.17 | 1.95 | |
| 2# | 2.09 | 1.95 | 1.97 | 1.97 | |
| 3# | 2.10 | 1.93 | 2.16 | 1.93 |
Observations: Airflow at the open port in the mixed configuration (485–488 NL/M) is approximately double that of the nozzle-fitted port (217–237 NL/M) in the same configuration, consistent with the restriction introduced by the nozzle. When both ports carry nozzles, airflow per port (241–247 NL/M) is reduced relative to the no-nozzle condition (434–450 NL/M), as expected. Air pressure readings remain stable across all configurations and samples, ranging from 1.93 to 2.17 psi, indicating a consistent pump output. No anomalies or remarks were recorded for any sample.

Frequently Asked Questions
What does the airflow reading difference between the nozzle port and the open port mean in the mixed configuration?
When one port has a large nozzle fitted and the other is left open, the nozzle restricts airflow at its port (217–237 NL/M) while the unrestricted open port delivers roughly double the volume (485–488 NL/M). This is expected behavior: the nozzle introduces back-pressure that diverts more air through the free port. It does not indicate a fault in the pump.
Why are two separate metrics — airflow (NL/M) and air pressure (psi) — tested?
Airflow (volume per unit time) and air pressure (force per unit area) measure different aspects of pump performance. High airflow ensures balloons fill quickly; sufficient pressure ensures the pump can overcome the resistance of the balloon material. Testing both confirms the P400 is capable across real-world inflation scenarios, not just under ideal low-resistance conditions.
What nozzle should be used with the P400 for balloon inflation?
The test was conducted using large air nozzles (大气嘴), which are the standard nozzle type supplied with the P400. Using the correct nozzle type is important because nozzle geometry directly affects the airflow and pressure readings at the outlet, as demonstrated by the configuration comparisons in this report.
How many samples are required to validate a production batch for the P400?
This test used three samples (1#, 2#, 3#) as a representative set. The close agreement between all three units across all configurations supports confidence in production consistency. For formal batch qualification, refer to ETENWOLF’s internal sampling plan, which may specify a larger sample size depending on batch volume.
