Product catalog summary
Specification Overview
The document is a technical specification for the WM6840-24V radial blower, issued on May 6, 2024, by Zhejiang Weicheng Blower Co., Ltd. It includes details on matching drive models, requests and revision records, technical specifications, curves and characteristics, outline drawings, and PCB control.

Technical Specifications
The blower operates at a rated voltage of 24V with a rated current of 1.5A and power consumption of 36W. It has a free blowing speed of 37,000 rpm, a maximum air pressure of 5.3 kPa, and a maximum air flow of 298 L/min. The BLDC motor parameters include a resistance of 1035 mΩ, inductance of 675 mH, and rotor inertia of 11.9 g/cm². The motor has a winding insulation level of 155°C-F and an IP level of IP50.

Performance and Materials
The blower's performance includes a noise level of 45 dB(A) and an operational life of 30,000 hours. The impeller and casing are made of PC material, and the blower is oxygen compatible at 21% and biocompatible. The operating temperature range is -10°C to 45°C, with a humidity range of 10% to 45% RH.

Curves and Characteristics
The document includes pressure and flow curves, as well as speed and power versus flow characteristics, illustrating the blower's performance under various conditions.

Connector and Wiring Details
The connector picture and wiring details specify a VH3.96-3P model with a wire length of 30cm. The wire colors are white (V), blue (W), and yellow (U), with a rubber shell model VH3.96-Y.

Important Notices
It is advised not to block the air inlet or outlet completely for more than 3 minutes, and the pipeline diameter should not be less than 6mm. An accelerated aging test is conducted at 45°C with continuous operation.
