The Yilida SYP series air-conditioning fan, used for fan coil only, is the forward multi-vane centrifugal metallic fan developed and manufactured first by our company in the country. The fan Wheels are made of high-quality hot galvanizing steel sheets by using stamping technology with the advantages of high efficiency, lower noise, and precision construction

Both the flow volume and pressure can meet with wide applications, and the diameter of the Wheel is from 130mm to 250mm. The flow volume ranges from 250m /h to 3000m /h. Our products have reached the advanced level and have replaced those imported ones first in the country. Now the products have a 55% share of the domestic market

SYP series fans mainly consist of housing, Wheel, and hub

• Housing: The housing is made of imported quality galvanizing sheets. Its side plates take the shape according to the aerodynamic profile and are fixed with biting-scroll with tapping screws
• Wheel: Forwards curved radial Wheel is made of high-grade imported hot-galvanizing steel punched with precision mold and curled. The reasonable design of the impeller makes the ventilator work in the optimum condition. The Wheel is fixed on the middle disk plate and on the end ring with riveting grippers. The Wheel has enough rigidity during continuous rotation with
  maximum power. All Wheels have passed by ANSI/AMCA-204 balance test according to the Company Standard which is a higher level than National Standard
• Hub: The connection of the Wheel with the electric motor shaft is guaranteed by the hub which is made of constructional steel door die-cast zinc alloy followed by precision processing. The permissible tolerance of hole diameter, per-perpendicularity, and coaxially are all kept within 0.01 mm

Features

According to the installed position of the hub, the fan can be divided into two types, right type and left type; viewing from the hub side, if the Wheel rotates clockwise, the fan is called the right type; if it rotates anti-clockwise, the fan is called left type

Instructions

1) Matching electric motor power of ventilation denotes internal power plus the safety coefficient of electric motor capacity in special operating conditions, it does denote the power required during the full opening of the air outlet. Therefore no-load running of the fan without any applied resistance is strictly prohibited in order to avoid burning out of the motor caused by its operation at overrated power
2) Special care should be taken during transportation, loading, and unloading. The fan is limited for use in areas where air substances are non-corrosive, non-toxic, and non-erosive
3) Prior to installing the fan, rotate the Wheel by hand or stick to check for tightness or impact. If it is ensured that there is no tightness and impact, then the installation can be carried out
4) After installing, the fan, the scroll of the fan should be inspected, There should not be tools and extra matters remaining in the casing
5) Prior to the official operation of ventilation, it is necessary to check the rotating direction of both motor and fan for their coordination
6) During ordering it is necessary to state the type of fan, speed, air volume, air pressure, the direction of air outlet, rotating direction, type of electric motor, and its specifications
