Our forward curved centrifugal fan, AC / EC TGZ series, also known as low pressure centrifugal fan, inch blower or housing fan, is developed and manufactured with internationally advanced. It was developed by using high technology and with low noise and compact structure, which was specially designed for the air-conditioning. Single-ended/double-ended extracting AC Centrifugal inch blower fan / EC centrifugal fan in the optimized spiral housing with forwards-curved blades. Energy-optimized for operation in a spiral housing for a high level of efficiency and favorable acoustic characteristics. Available in dimensions of 180 to 500 mm. This allows for volume flow rates of up to 9,000 m³/h and static pressures of up to 800 Pa. Low pressure centrifugal fan is the ideal subsidiary equipment for various cabinet central air conditioning unit, changeable air conditioners, tube unit, VAV system, heating, cleansing and other kind of ventilating system.
Tingertech fan meet the highest quality requirements in any application field. This means that the AC centrifugal fan and EC centrifugal fan in our TGZ series are perfectly suited for applications in air conditioning technology, device and component cooling, or for exhaust systems. Available in a number of dimensions from 180 - 500 mm, the centrifugal fans from our TGZ series in their spiral housing made of galvanized sheet metal can be mounted on the outlet flange or using fixing brackets. Our EC technology with integrated controller is perfectly tailored to the centrifugal fan. Naturally, centrifugal fans with EC motor meet the requirements of all relevant EU energy efficiency directives.
The rotation direction of HVAC Centrifuge Air Blower Fan can be divided into clockwise rotation (R) and counterclockwise rotation (L).
Clockwise rotation (R) of AC Centrifugal Fan Blower: From the sleeve side, the Wheel rotation direction is the same as the clockwise direction of rotation.
Counterclockwise rotation (L) of double inlet centrifugal fan: From the sleeve side, the Wheel rotation direction is opposite to the clockwise direction of rotation.
Shown as below figure, inline rectangular duct fan can be made in four air-outlet directions: 0°, 90°, 180°, and 270°.

TGZ series ventilators consists of housing , Wheel ,base plate and motor.
The housing of centrifugal fan blower is made of hot galvanized steel sheet. The side plates include inlets cones that are designed with the best aerodynamics for inlet condition. The scroll of centrifuge blower 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 air outlet direction needed by the customer.
Forward curved centrifugal fan wheel of industrial centrifugal fan is constructed of high-grade hot galvanized steel sheet with the 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 the continuous operation with maximum power.
Base plates of housing fan are made of high-quality galvanized steel sheet, which can be assembled with the direction by the customer demand.
Centrifugal Fan motors for blower can be single-phase AC motors of 220V/50HZ, 110V/60HZ with 1-3 speeds OR EC motors with 1-3 speeds, which are flexible to change speed and easy to install. Speed can be changed by using provided silicon controlled voltage regulator and frequency converter.
