Description

DWT-II Type FRP Centrifugal Roof Fan

The DWT-II Type FRP Centrifugal Roof Fan is a high-pressure, corrosion-resistant ventilation unit designed for roof installation. Constructed entirely from fiberglass composite material, it is ideal for applications requiring higher static pressure, such as industrial facilities, warehouses, and commercial buildings.

DWT-II Model Features

Material & Structural Properties

· The base, impeller, and wind cap are all constructed from high-quality fiberglass composite material, offering excellent corrosion resistance against acids, alkalis, and corrosive chemicals.

· Centrifugal design delivers higher static pressure compared to axial roof fans, making it suitable for systems requiring more pressure.

· Compact, aerodynamic design with a durable, weatherproof housing.

· Optimized impeller for high efficiency, low noise, and reliable operation.

Core Advantages

· High Static Pressure: Centrifugal design provides significantly higher pressure than standard axial roof fans, making it ideal for long duct runs or high-resistance systems.

· Full FRP Construction: Corrosion-resistant fiberglass composite material ensures long-term performance in corrosive and outdoor environments.

· Low Noise & Energy Efficient: Optimized impeller design delivers high airflow with minimal noise and power consumption.

· Easy Installation & Maintenance: Roof-mounted design with simple access for inspection and maintenance.

Transport Medium Restrictions

The conveyed gas must not contain sticky substances. The concentration of dust and hard particles must not exceed 150mg/m³. The gas temperature must be ≤60°C, and the relative humidity can be up to 100%.

Model Selection

The series includes models from 3A to 10A, with power ranging from 0.55kW to 18.5kW and speeds from 720r/min to 2900r/min.

Q1: What is the primary application of the DWT-II fan?
A1: It is designed for roof-mounted ventilation in industrial facilities, warehouses, and large commercial buildings requiring higher static pressure.
Q2: How is this fan different from axial roof fans?
A2: The centrifugal design delivers significantly higher static pressure, making it ideal for systems with longer duct runs or higher resistance.
Q3: Why is this fan made of FRP?
A3: The fiberglass composite material provides excellent corrosion resistance against corrosive gases and weather conditions, making it ideal for industrial and outdoor applications.
Q4: Can this fan be installed on any type of roof?
A4: Yes, it is designed for installation on flat or low-slope roofs with standard mounting bases.
Q5: What are the operating limits for temperature and humidity?
A5: The maximum gas temperature is 60°C, and it can operate in high humidity environments up to 100% relative humidity.
Q6: Can the fan handle dust-laden air?
A6: Yes, but the dust and hard particle concentration must not exceed 150mg/m³, and the gas must not contain sticky substances.
Q7: Is this fan suitable for continuous operation?
A7: Yes, it is designed for 24/7 continuous operation with low noise and vibration.
Q8: How do I select the right model for my project?
A8: Select based on your required airflow (m³/h) and static pressure (Pa). Our technical team can help you choose the best model based on your specific application.
Q9: Does the fan require regular maintenance?
A9: It has minimal maintenance requirements, with easy access to the motor and impeller for inspection and cleaning.
Q10: What after-sales support do you provide?
A10: Each unit includes a detailed installation and operation manual, and we offer full after-sales technical support.
