Customization & OEM Support
Every OEM machine application presents unique physical envelope constraints and operating pressures. Delco provides end-to-end custom engineering for centrifugal blower designs:
Aerodynamic Tuning
Impealler width, blade angle, and scroll casing radius optimized for target CFM vs static pressure performance curves.
Mechanical Integration
Custom mounting flanges, discharge orientations (0°, 90°, 180°, 270°), and specialized mounting brackets.
Environmental Protection
Anti-corrosive coatings, stainless steel housings for humid/chemical environments, and high-temp shaft extensions.
Motor Drive Options
Integrated AC induction motors, shaded pole drives, or energy-efficient EC (Electronically Commutated) variable speed motors.
Industrial Applications
Delco Centrifugal Blowers are widely installed across mission-critical equipment where air movement accuracy is non-negotiable:
HVAC & Cleanroom Systems
Air handling units (AHU), fan coil units, laminar air flow benches, and cleanroom HEPA filter modules.
Medical & Laboratory Devices
Fume containment hoods, bio-safety cabinets, sterilizers, and medical equipment cooling.
Industrial Enclosure Cooling
Electrical control panel ventilation, drive cabinet heat dissipation, and transformer forced cooling.
Drying & Exhaust Processing
Industrial printing dryers, food dehydration systems, weld fume extraction, and dust collectors.
Quality Control & Verification
Each unit produced at our Thane manufacturing facility undergoes a rigorous quality routine prior to packing:
- Two-plane dynamic balancing of impellers to eliminate radial and axial vibration
- Full electrical safety testing including high-voltage flash test and insulation resistance
- No-load running, current draw, power consumption, and speed verification
- Airflow and static pressure validation on calibrated wind-tunnel test rigs
