application scenarios
The Anticorrosion Ex Proof Pipeline Fan serves multiple demanding industrial ventilation applications. Primary applications include exhaust of flammable gas and vapor from petroleum processing zones. Additionally suitable for grain silo and flour mill dust-laden air ventilation. Also widely deployed for wastewater treatment plant biogas area ventilation. The carbon steel construction with pure copper coil motor, reinforced safety mesh grille and energy-efficient design ensures reliable continuous-duty performance across these and many other ventilation and air circulation requirements.
Customised processing workflow
OEM and ODM customization follows a proven six-step workflow.
Phase 1: Provide target voltage, color, fan diameter and performance requirements.
Phase 2: Engineering team delivers comprehensive proposal with pricing, MOQ and lead time.
Phase 3: Pilot unit produced for hands-on evaluation and specification confirmation.
Phase 4: Bulk production activated upon sample approval.
Phase 5: Production through CNC machining, winding, assembly and calibrated testing stations.
Phase 6: Final inspection, export-grade packaging and global dispatch.
Packaging and Transportation
Each axial flow fan is individually packed in a reinforced export-grade carton with custom-cut foam cushioning protecting the housing, grille and motor assembly. Multiple units are palletized on fumigated wooden pallets wrapped in moisture-barrier film and secured with industrial strapping. All packaging meets international ISPM-15 phytosanitary standards. Clear product labeling and handling markings are applied to every carton. Custom branded retail packaging is available for distributors and volume OEM partners.
Factory Introduction
Taizhou Yijia Mechanical and Electrical Co., Ltd. is a specialized manufacturer of industrial axial flow fans, high-pressure blowers and comprehensive ventilation accessories. The production facility integrates CNC sheet metal fabrication, precision machining, motor winding, assembly, quality testing and finishing operations under one roof. Each axial fan undergoes individual performance verification - testing airflow, pressure, current draw, noise level and vibration - before receiving its QC certification label. The company serves equipment OEMs, industrial distributors and end users worldwide with consistent product quality, competitive pricing and responsive after-sales support.
FAQ
Q: What is an axial flow fan and how does it work?
A: An axial flow fan moves air parallel to its rotating shaft using angled blades that push air in the axial direction. This produces high air volume at relatively low pressure, making it ideal for general ventilation, cooling and exhaust applications. Unlike centrifugal blowers that change airflow direction 90 degrees, axial fans maintain a straight-through airflow path for efficient high-volume air movement.
Q: What voltage and frequency configurations are available?
A: The SF series duct, pedestal and fixed-mount fans support 220V single-phase and 380V three-phase configurations at both 50Hz and 60Hz. The CBF explosion-proof series operates on 220V/380V. Custom voltage and frequency configurations are available through our OEM service. Please specify your electrical requirements when placing your order.
Q: Can the axial fan run 24 hours a day continuously?
A: Yes, all Yijia axial flow fans are engineered for continuous-duty operation within their rated specifications. The carbon steel housing, aluminum alloy blades, pure copper motor winding and sealed bearings support 24/7 operation. Ensure adequate clearance around the motor for cooling airflow and keep the safety grille unobstructed during operation.
Q: What routine maintenance does an axial flow fan require?
A: Axial flow fans require minimal routine maintenance. Periodically clean the safety grille and fan blades to remove accumulated dust, which can reduce airflow efficiency and cause imbalance. Check mounting bolts and electrical connections every 6 months. The sealed motor bearings require no lubrication under normal operating conditions. Inspect the power cable for damage periodically.
Q: How do I select the correct fan size for my application?
A: Calculate the required air volume by multiplying your room volume by the target air changes per hour (typically 6-12 for general ventilation). Select a fan model whose rated airflow equals or exceeds this requirement. Add a 20 percent safety margin if the fan will be connected to ducting. Our technical team can assist with sizing calculations for complex installations.
Q: Can the fan be installed outdoors or in wet environments?
A: The standard SF series is rated for indoor and sheltered outdoor use - under a roof or canopy away from direct rain. For fully exposed outdoor installations, specify the weather-resistant configuration with sealed motor and additional corrosion protection when ordering. The CBF explosion-proof series is designed for harsh industrial environments but should still be sheltered from direct precipitation.
Q: Do you offer explosion-proof certified models?
A: Yes, the CBF series features Ex d IIB T4 certified explosion-proof motors suitable for Zone 1 and Zone 2 hazardous areas where flammable gases or vapors may be present. Available in 300mm, 400mm, 500mm and 600mm diameters, these fans are ideal for chemical plants, paint spray booths, petroleum facilities, grain silos and pharmaceutical production areas requiring certified safety equipment.
Q: How noisy are these fans during operation?
A: Operating noise varies by model size and pole count. The SF-2 series runs at approximately 55-60 dB(A), while larger SF-6 models reach about 70-75 dB(A) at rated speed. Two-pole high-speed models produce more noise than four-pole low-speed variants of the same diameter. For noise-sensitive installations, select a four-pole model and use flexible duct connections with vibration-isolating mounts to minimize structure-borne sound transmission.
Q: What is the minimum order quantity and typical delivery time?
A: Sample orders of single units are welcome for evaluation before bulk purchasing. Standard stock models ship within 3-7 business days. Custom OEM orders with special voltage, color or branding typically require 15-25 business days depending on volume and customization complexity. Contact our sales team for current stock availability and precise delivery schedules.
Q: What warranty is provided and how is after-sales service handled?
A: All Yijia axial flow fans carry a 12-month manufacturer warranty from the shipment date, covering defects in materials and workmanship under normal operating conditions. Our after-sales team provides support via email, WhatsApp and video call during business hours. For warranty claims, we offer replacement parts shipment or repair guidance within 5 business days of confirmed diagnosis. Extended warranty options are available for OEM partners.
