SF-A Series Selection Guide & Specs

SF-A Series: Low-Noise Moisture & Oil Proof Axial Fan technical and selection table
Model Voltage / Power Speed (RPM) Airflow (m³/h) Size (Blade Ø) Best For
SF-A-2-2 220V / 0.18kW 2900 (High) 1,350 200mm (8″) Spot Cooling: Best for soldering stations, small bathrooms, or cooling specific machinery.
SF-A-2.5-4 220V / 0.12kW 1450 (Low) 1,000 250mm (10″) Quiet/Small: Ideal for small hobby rooms or pet ventilation where silence is a priority.
SF-A-3-2 220V / 0.37kW 2900 (High) 3,500 300mm (12″) Garage Venting: Perfect for a standard 1-car garage or shed to vent fumes quickly.
SF-A-3.5-4 220V / 0.37kW 1450 (Low) 4,000 350mm (14″) Greenhouse Choice: Moves high volume gently. Great for humidity control without wind-burning plants.
SF-A-4-4 220V / 0.55kW 1450 (Low) 5,870 400mm (16″) Kitchen Hoods: Strong airflow for food trucks or medium kitchens. Handles grease well.
SF-A-5-4 220V / 0.75kW 1450 (Low) 10,000 500mm (20″) Workshops: High volume air exchange for woodworking shops or medium warehouses (approx 100sqm).
SF-A-6-4 220V/380V / 2.2kW 1450 (Low) 18,700 600mm (24″) Industrial: Heavy-duty ventilation for factories or large paint booths.
SF-A-7-4 380V / 3.0kW 1450 (Low) 26,000 700mm (28″) Max Power: For large-scale facilities. Requires 3-Phase Industrial Power.

> Note: “High Speed” (2900 r/min) models are louder and designed for maximum suction. “Low Speed” (1450 r/min) models are quieter and designed for constant ventilation.

Where to Use It? (Scenario-Based)

  • Commercial Kitchens: Ejects heat and cooking grease without the motor seizing up.
  • Greenhouses & Grow Rooms: Handles 90%+ humidity 24/7 without rusting or electrical shorts.
  • Workshops & Garages: Clear welding fumes, sawdust, and summer heat rapidly.
  • Paint Booths: Provide consistent airflow for drying without kicking up dust.

> Note: This product is suitable for environments with high humidity or relatively high temperatures (Ambient temperature must not exceed 60°C).

Where This Series Fits

SF-A Moisture & Oil Proof Axial Fan is positioned for export buyers who need a practical ventilation model range rather than a single generic fan. Use it when the installation environment, airflow target and voltage are already roughly known.

Selection guide

Do not select only by fan diameter. Airflow, pressure, duct resistance, mounting location, voltage/frequency, noise target and ambient conditions all affect the final model.

Frequently Asked Questions

How should I choose a SF-A Moisture & Oil Proof Axial Fan model?

Start with required airflow, pressure or duct resistance, fan size, voltage and the actual installation environment.

Can this fan be used in oily or humid areas?

This series is intended for moisture or oil resistant ventilation conditions, but the exact ambient temperature, exposure level and installation method should be confirmed for final selection.

What information should I send for quotation?

Please send the target airflow, mounting position, voltage/frequency, operating temperature, humidity or oil exposure and any noise requirement.

Quality Assurance & Warranty

Fan orders are checked at the factory before shipping, because published airflow and pressure only hold if the delivered unit matches its table row.

Applied to this model: Voltage / Power 220V / 0.18kW, Speed (RPM) 2900 (High). These checks are run against that specification before the unit ships.

Airflow and pressure checkChecks cover motor start-up, impeller balance, airflow and static pressure verification, noise review and model-to-table parameter matching.
Documented complianceCE, RoHS and related files cover the listed fan families; see the documents section below.
Warranty supportWarranty for fan orders is confirmed with the quotation for your destination market.
Service parts for fansImpellers, motor capacitors, mounting brackets and common service items.
