Engineering Overview

High-Performance Dual-Sided Centrifugal Blowers for Global OEMs

Delco customized AC fractional horsepower (FHP) centrifugal blowers are specifically developed to address demanding airflow and static pressure requirements in space-constrained industrial systems. Featuring a balanced dual-sided impeller configuration, these blowers intake air from both lateral sides to double air volume distribution while maintaining low operating noise and vibration.

Manufactured entirely in-house at our facility in Thane, India, every unit combines precision motor winding, dynamically balanced impellers, and rugged housing construction. Backed by over 50 years of motor and blower manufacturing experience, Delco works directly from OEM drawings and operational profiles to deliver reliable, long-life air movement solutions.

Why Engineers Specify Delco Dual-Sided Blowers

Dual-Sided Impeller Intake

Draws air laterally from both ends of the central FHP motor, maximizing CFM volume output per millimeter of cabinet depth.

Tailored Duty & Airflow

Engineered for continuous-duty operation with tailored speed, static pressure, and thermal insulation classes (Class B or F).

Dynamic Balancing

Precision-balanced impellers ensure minimal rotational vibration, low acoustic emissions, and extended sleeve/ball bearing longevity.

Versatile Voltage Builds

Compatible with international electrical systems (110V-240V, 50Hz/60Hz, single-phase configurations).

Key Industrial & OEM Applications

HVAC & Air Handling Units (AHUs)

Ideal for compact duct boosters, ceiling-concealed fan coil units, and split-system ventilation modules requiring high static delivery.

Industrial Panel & Enclosure Cooling

Maintains safe interior temperatures for electrical control panels, power inverter cabinets, and automation drives.

Dust & Fume Extraction

Draws contaminated air or welding fumes through filtration packs where system static resistance is elevated.

Commercial & Medical Devices

Quiet, reliable air circulation inside laboratory incubators, sterilizing equipment, and commercial food warmers.

Quality Assurance & Manufacturing Discipline

Every Delco centrifugal blower undergoes multi-point quality validation at our plant before shipment to international destinations. Routine testing procedures include:

TEST 01

Electrical & Dielectric Strength

Routine high-voltage insulation tests, current draw analysis, and winding resistance verification.

TEST 02

Dynamic Balance & Vibration

Dual-plane dynamic balancing of impellers to prevent operational noise and bearing wear.

TEST 03

Thermal Rise & Continuous Duty

Full-load thermal rise checks under rated ambient conditions to verify insulation rating.

TEST 04

Airflow & Pressure Validation

Sample performance curve checks against standard test ducting to confirm flow performance.

Frequently Asked Questions

A dual-sided centrifugal blower utilizes an impeller design that draws intake air from both left and right sides of the assembly. Powered by a central AC FHP motor, it discharges high-volume airflow through a central outlet, ideal for applications needing compact installation and uniform air distribution.
Dual-sided blowers deliver higher volume airflow (CFM) without increasing the diameter of the impeller housing. This makes them significantly more space-efficient for shallow cabinetry and equipment frames.
Yes. Delco supplies international buyers with custom motor windings tailored to 110V 60Hz, 220V-240V 50Hz, or dual-voltage requirements, compliant with overseas electrical specifications.
