3.3″ Diameter Motor Blower by P-Tech HVAC Fan – 135 CFM, 3200 RPM

Description

Product Overview

The P-Tech 3.3″ Diameter Motor Blower is engineered to meet the demanding requirements of modern HVAC systems, material handling equipment, and industrial circulation applications. Constructed from high‑grade steel and precision‑molded polymer components, the blower delivers a steady airflow of 135 cubic feet per minute (CFM) while operating at a robust 3200 revolutions per minute (RPM). The single‑speed motor, rated at 1/25 horsepower and drawing only 1.3 amps at 115 volts, provides a balance of power and energy efficiency that reduces operating costs without sacrificing performance. With a compact footprint of 10 × 9.25 × 9 inches and a lightweight design of 6.39 lb, the unit can be easily mounted in confined spaces, making it an ideal retrofit solution for existing fan assemblies. The blower’s internal bearings are sealed to protect against dust and moisture, extending service life and minimizing maintenance intervals. Additionally, the product includes a one‑year manufacturer warranty, underscoring P-Tech’s confidence in the durability and reliability of the design.

Usage

Designed for versatility, this motor blower excels in a variety of environments ranging from commercial HVAC installations to industrial material handling stations. In commercial buildings, the blower can be integrated into air handling units (AHUs) to improve ventilation efficiency and maintain consistent indoor air quality. Its high airflow capacity makes it suitable for large‑scale cooling towers, where rapid heat exchange is essential. In manufacturing facilities, the blower can be employed to circulate air across workstations, reducing temperature gradients and enhancing worker comfort. The unit’s 115‑volt, 60/50 Hz compatibility ensures seamless operation in both North American and international power grids, while the single‑speed configuration simplifies wiring and reduces the need for complex control systems. Because the blower replaces legacy models such as the Dayton 1TDR6, 4C006, and Fasco B24220, it offers a cost‑effective upgrade path for facilities looking to modernize equipment without extensive redesign. Its quiet operation, measured at less than 55 dB(A), also makes it suitable for noise‑sensitive environments like hospitals, laboratories, and office spaces.

FAQ

What size fan housings are compatible with this blower?

The 3.3″ diameter motor blower is designed to fit standard fan housings that accommodate a 3.3‑inch shaft and a mounting flange of 10 × 9.25 inches. It directly replaces Dayton models 1TDR6 and 4C006 as well as the Fasco B24220, making it a drop‑in solution for many existing installations.

Can this blower be used with variable frequency drives (VFDs)?

While the blower is optimized for single‑speed operation, it can be paired with a VFD for speed control if the application requires variable airflow. However, using a VFD may affect the motor’s efficiency curve and should be evaluated by a qualified engineer to ensure optimal performance.

What is the expected noise level during operation?

Under normal operating conditions, the blower produces sound levels below 55 dB(A), which is comparable to a quiet conversation. This low noise output makes it suitable for environments where acoustic comfort is important, such as offices, clinics, and educational facilities.

How does the warranty process work if the unit fails?

If the blower experiences a failure within the one‑year warranty period, customers should contact P-Tech’s technical support team with the purchase details and a description of the issue. After verification, a replacement unit or repair service will be arranged at no additional cost, ensuring minimal disruption to operations.

Is the blower suitable for outdoor installations?

The blower’s sealed bearing design and corrosion‑resistant coating allow it to operate in outdoor settings, provided it is installed in a protected enclosure that shields it from direct exposure to rain and extreme temperatures. For fully outdoor applications, additional weatherproofing measures are recommended.
