LTW Series Forward-curved-blade Double-inlet Centrifugal Fan With Outer Rotor Motor
LTW series fans are centrifugal fans with forward-curved-blade, double-inlet, with external rotor motor placed in the air stream, provided with impulse turbines with a large number of narrow, direct-drive blades.
Wheel Diameters
7~19.44 inches (180mm~500mm)
Standard Performance Range
Airflow: min 238 CFM ～max 19,643 CFM ( 400 m3/h～33,000 m3/h, 14,125.87 ft³/h~1,165,384 ft³/h)
Static pressure: 0.36~4 inches w.g. (90～1,000 pa)
Application Model
Our fans can be typically used for all types of buildings, such as homes, offices, airports, malls, applied for air handling unit, restroom exhaust, parking garage exhaust, sidewall supply and exhaust, kitchen exhaust, elevator shaft exhaust.
Features
The external rotor motor is adopted, which is compact in structure, small in size, light in weight and easy to install; Its forward multi wing impeller with high pressure, low noise, high efficiency and environment friendly.
About Installation
The blades are set forwards, tilted in the direction of rotation. The direction of the air outlet can be different directions of 0 °, 90 °, 180 ° or specially customized, and the installation form is flexible and convenient;
( facing the motor’s lead wire, the clockwise direction of impeller rotation is called CW, and the counter-clockwise direction of impeller rotation is called CCW. )
About Mobile Use
Our self-developed matching electric motors have better reliability and service life and support mobile use with battery group or other mobile power supply;
About Power Supply & Speed Mode
Power supplies single-phase, three-phase, DC power supply, voltage and frequency customized;
Speed modes of single-speed, double-speed, three-speed and stepless speed regulation available to meet the needs of users for air volume regulation.
