Yilida SYZ series centrifugal air-conditioning fans are based on the SYT series, which are newly developed and manufactured products internationally advanced by this company. It was developed by using high technology with low noise and a compact structure. It was specially designed for air-conditioning. The flow rate and total pressure range of this series fan are from 800m /h to 5000m /h. It is the ideal equipment for changeable air conditioners, tube-type units, VAV systems, heating, and another kind of fan systems.

Features

1. Rotation direction: The rotation direction of the fan can be divided into clockwise rotation (R) and counterclockwise rotation (L). Clockwise rotation (R): From the sleeve side, the Wheel rotation direction is the same as the clockwise direction of rotation. Counterclockwise rotation (L): From the sleeve side, the Wheel rotation direction is opposite to the clockwise direction of rotation
2. Discharge Direction: According to Fig1, SYZ Series fans can be made in four air-outlet directions:0°, 90°, 180°, and 270°

Construction

SYZ series ventilators consist of a housing, Wheel, baseplate, and motor

1. Housing: The housing is made of a hot galvanized steel sheet. The side plates include inlet cones that are designed with the best aerodynamics for inlet conditions. The scroll is fixed to the side plates by spot welding. On the side of the housing, there are a series of holes drilled in advance for riveting nuts to carry out installation according to the air outlet direction needed by the customer
2. Wheel: Forward curved Wheel is constructed of high-grade hot galvanized steel sheet with an advanced aerodynamics profile to achieve the highest efficiency and the lowest noise level. The wheel is fixed on the center plate and on the end ring with riveting grip pres. The Wheel is constructed with maximum strength that endures continuous operation with maximum power. All Wheels are balanced to the ANSI/AMCA 204 Notional Standard. Yilida’s internal standard is G2.5 or higher for wheel balancing
3. Frame: SYZ series fan baseplates are made of high-quality galvanized steel sheet, which can be assembled with the direction of the customer’s demand
4. Motor: SYZ series fans are equipped with single-phase 220V/50HZ three speeds motors, which are flexible to change speed and easy to install, Speed can be changed by using provided silicon-controlled voltage regulator and frequency converter
5. Flange: The flange is made of galvanized steel. The connections of the flange components to the scroll are made using a TOX non-welding process. This maintains a good flange appearance while also providing sufficient strength and rigidity
