Technical Drawing Request and Model Specifications

On August 10, 2026, LONGWELL opened a project to provide technical engineering drawings for three cross flow fan configurations: LWCA-100720SN-06, LWCE-90800SN-06, and LWCE-100720SN-06. The engineering team reviewed the required parameters and generated standard specification drawings, which completed technical review on August 13, 2026.

Documented Specification Details

The technical drawings outline dimensional and electrical specifications for the cross flow blower models. Model LWCE-100720SN-06 incorporates an EC92 motor operating on a 230V, 50/60 Hz supply, controlled via 0-10 VDC or PWM signals, with a specified rated air volume of 1500 ±10% m³/h at 1500 ±150 r/min. Model LWCE-90800SN-06 utilizes an EC72 motor rated at 230V, 50/60 Hz, with a specified air volume of 1300 m³/h at 1500 ±150 r/min. Both EC models feature ball bearings and integrated control wiring.

Model Motor Type Rated Voltage Frequency Speed Control Rated Speed Air Volume
LWCE-100720SN-06 EC92 230V 50/60 Hz 0-10 VDC / PWM 1500 ±150 r/min 1500 ±10% m³/h
LWCE-90800SN-06 EC72 230V 50/60 Hz 0~10V/PWM 1500 ±150 r/min 1300 m³/h

Engineering drawings for the models define the physical interface dimensions, motor wiring layouts, and blade assembly details for customer fit evaluation.
