Keruite's sales team in Colombia reports a significant shift in axial fan specifications for laboratory projects over the past 12 months. Higher efficiency requirements, combined with longer lead times for custom configurations, are changing how projects are planned and procured. Here is what we are seeing.
Current Situation
The laboratory sector in Colombia is experiencing increased demand for high-efficiency axial fan systems, driven by rising energy costs and stricter compliance requirements. Projects specifying equipment in the 500 to 5,000 m3/h range at 200 to 800 Pa represent a growing segment, with motor ratings typically between 30 kW and the next size up.
The IE2 motor class is now the minimum specification for most new projects, and ISO 9001 certification is increasingly required for laboratory applications.
For laboratory projects in Colombia, the procurement process for a axial fan should begin at least 12 to 16 weeks before the required on-site date. This allows time for engineering review, factory testing, and shipping. Custom specifications โ such as non-standard materials (stainless steel 316L), special motor ratings (30 kW), or additional certifications โ may extend lead times to 20 weeks. Planning for these timelines early avoids the premium pricing and quality risks associated with rush orders.
Technical Considerations
Several technical factors affect axial fan performance in laboratory applications. The operating temperature range (-10 to 50 C) influences material selection (stainless steel 316L) and motor derating requirements. The noise specification (55 to 75 dB(A)) may require silencers or acoustic enclosures. And the certification requirements (ISO 9001, ISO 9001) affect both the equipment specification and the documentation package.
For projects in Colombia subject to ISO 13349 and ISO 13349, the documentation requirements have become more detailed over the past two years, adding approximately 3 to 5 percent to engineering costs but reducing installation inspection delays.
The choice of stainless steel 316L for a axial fan in a laboratory application involves balancing initial cost against lifecycle performance. In mildly corrosive environments, galvanized steel with an epoxy coating can extend service life by 5 to 8 years compared to uncoated steel. In severely corrosive environments, stainless steel or FRP construction may be required despite the higher initial cost, because the alternative is premature equipment replacement at 3 to 5 years.
Practical Recommendations
For procurement teams specifying axial fan equipment, budget an extra 5 to 10 percent for the IE2 motor upgrade and factor in the energy savings over the equipment life. Compliance with ISO 13349 requirements may also affect the project timeline. Request certified performance data from the manufacturer rather than relying on calculated values.

| Parameter | Specification |
| Airflow Range | 500 to 5,000 m3/h |
| Static Pressure | 200 to 800 Pa |
| Motor Power | 30 kW (IE2) |
| Material | stainless steel 316L |
| Temperature Range | -10 to 50 C |
| Impeller Balance | G6.3 (ISO 1940) |
| Noise Level | 55 to 75 dB(A) |
| Certifications | ISO 9001, ISO 9001 |
| Standards | ISO 13349, ISO 13349 |
Procurement and Lead Time Planning
For laboratory projects specifying axial fan equipment in Colombia, procurement should begin 12 to 16 weeks before the required delivery date for standard configurations (stainless steel 316L construction, ISO 9001 certified). Custom specifications such as special materials or multiple certifications (ISO 9001 and ISO 9001) may extend lead times to 20 weeks.
When requesting quotations, provide the complete specification including airflow (500 to 5,000 m3/h), pressure (200 to 800 Pa), operating temperature (-10 to 50 C), noise requirement (55 to 75 dB(A)), and certification requirements. Incomplete specifications lead to assumptions that may not match actual site conditions.
Documenting System Performance
A axial fan in a laboratory application should have a performance record that starts at commissioning and continues throughout its service life. The initial record includes the certified performance curve, commissioning measurements (airflow, pressure, motor current, vibration), and the design point comparison. Subsequent entries record maintenance activities, performance changes, and any modifications.
This record is essential for warranty claims, ISO 9001 and ISO 9001 compliance audits, and replacement planning. In Colombia, regulatory inspections often request this documentation, and having it organized and current significantly reduces the inspection time.
Common Specification Mistakes
After reviewing hundreds of axial fan specifications for laboratory projects, several recurring mistakes stand out. The most common is specifying only design airflow and pressure without stating the actual system curve. The second is neglecting system effect, which can reduce delivered airflow by up to 20 percent. The third is under-specifying material requirements โ a axial fan in a mildly corrosive environment will develop impeller fouling within 3 to 5 years if stainless steel 316L is used without appropriate protection.
Other frequent issues include forgetting to specify the motor efficiency class (IE2 should be the minimum for new installations), not requiring factory performance test data, and omitting noise requirements (55 to 75 dB(A)).
Conclusion
From specification to long-term operation, a axial fan in a laboratory application performs best when the engineering basics are done right.
