9.84~49.21inches (250mm~1250mm)
Standard Performance Range
Airflow: min 803 CFM ～max 88,357 CFM ( 1,350 m3/h～148,500 m3/h, 47,674.81 ft³/h~5,244,229 ft³/h)
Static pressure: 0.98~55.17 inches w.g. (250～1,600 pa)
AHU Application
The AHU system (Air Handling Unit) is a set of independent air treatment system composed of air supply system and exhaust system, which is comprised of Make-Up Air Units (MAU), Packaged Units (PU), Rooftop Units (RTU), and Energy Recovery Units (ERU).
The AHU system is based on sending fresh air to the room with special equipment on one side of the closed room, and then discharging it to the outside with special equipment on the other side. The "fresh air flow field" will be formed indoors, so as to meet the needs of indoor fresh air exchange. The implementation scheme is: using high wind pressure, large flow fan, relying on mechanical strength, from one side of the indoor air supply, from the other side with a specially designed exhaust fan to the outside to force the formation of new air flow field in the system. Filter, disinfect, sterilize, oxygenate and preheat the air entering the room while supplying fresh air in winter.
Features
This series use the belt drive mode which can have configuration of rated flow and pressure freely.
Model Definition
Such as LTB300L-4 is centrifugal air conditioning fan, forward curved blade, blade diameter 300mm with large width, motor poles 4.
About Installation
1. The installation of LTB series centrifugal fan has three main types according to the outlet angle (between fan outlet and mounting surface): 0 °, 90 °, 180 °. It can also be customized to other directions according to the needs of users.
2. The rotating direction of centrifugal fan is divided into CW and CCW according to the rotating direction of impeller. To Belt-drive Centrifugal Fans: facing the fan pulley, the clockwise direction of impeller rotation is called CW, and the counter-clockwise direction of impeller rotation is called CCW.
*** The default rotation direction of our centrifugal fans is CW. If users want different rotation directions, must point out clearly at the time of ordering. ***
